Best Protein Powders for Muscle Gain | Fortune Recommends Health (2024)

Before protein became the “it” nutrient for everyone, it was primarily recognized as essential for athletes and bodybuilders who rely on it to build muscle. While consuming large quantities of egg whites and chicken may be an option for some people, protein powders offer a simple and more convenient way to increase protein intake.

Best overall protein powder for muscle gain: Nutricost Grass-Fed Whey Protein Isolate

Why we like Transparent Labs Whey Protein Isolate as best for men

With 28 grams of grass-fed whey protein isolate per serving, Transparent Labs Whey Protein Isolate was an easy choice for the best protein powder for men who want to gain muscle. ( 7 ) While males have a larger body size and more muscle mass than females, they also have an easier time accumulating muscle mass. ( 8 )

And yet, body size and body composition influence nutrition needs. ( 1 ) Men working out to gain muscle have higher protein needs, and protein powders are a convenient way to meet those elevated needs and achieve fitness goals. ( 9 )

This protein powder also has a good protein-to-calorie ratio for building lean muscle, with 86% of calories coming from protein. And with only 1-3 grams of carbohydrates, it’s nearly lactose-free and may be easier to digest, and less likely to cause gas or bloating. This was pointed out by one of our product testers who said that the Transparent Labs supplement didn’t upset his stomach like other protein powders.

We also like Transparent Labs Whey Protein Isolate because it has very few ingredients and no artificial flavors, colors, or sweeteners. The protein powder uses stevia to add sweetness without adding carbs or calories.

Low carbs and low calories can be good when you want to improve muscle tone and physique, but if you want to bulk up you may need a higher-calorie protein powder, or mass gainer. In this case, Transparent Labs may not make the best choice.

“There are so many options available. It’s important to find the product that best suits your goals to meet your needs,” says Chris Mohr, Ph.D., RD.

Transparent Labs Whey Protein Isolate is third-party tested and gluten-free. Though not the least expensive muscle-building protein powder on our list, at $2.00 per serving we think it’s a good value for such a high-quality supplement.

One of our product testers said this was the best protein powder they’ve ever had, but not everyone agreed. One of our testers said it was chalky, and another said the powder didn’t dissolve well in the shaker cup or hand mixer.

What customers are saying

Customers who purchased Transparent Labs Whey Protein Isolate on Amazon like the ingredients, taste, and results. However, some customers experienced stomach problems from the drink, despite claims that it’s easier to digest.

Jason is an Amazon customer who likes the shake and the company’s customer service. “I like this protein. It tastes good and they reach out to you after you purchase to make sure you are 100% satisfied. What else could you ask for when buying something. This is unheard of now days,” he wrote.

TRC is a verified Amazon customer who thought the supplement was too pricey and didn’t like the flavor. “Not good at all when using water. It’s a little pricey, but probably provides the Protein needed,” they wrote.

Best vegan protein powder for muscle gain: Ka’Chava

Why we like Ka’Chava as best vegan

Ka’Chava is a complete nutrition shake higher in calories and carbs than the other protein powders on our list, making it our choice for the best vegan protein powder for muscle gain.

More and more people are eating plant-based diets to improve their nutrition and health, including athletes and bodybuilders. ( 10 ) Plant foods are nutrient-dense, but typically low in calories and filling because of their higher volume. Athletes and bodybuilders following a vegan diet may have a harder time getting enough calories and protein from whole foods.

A nutritionally complete, vegan protein shake like Ka’Chava fills in the gaps and helps meet nutrition needs and fitness goals. One serving (2 scoops or 60-62 grams) has 240 calories, 25 grams of protein, 21-25 grams of carbohydrates, and 7-8 grams of fat.

Though protein is king when it comes to muscle gain, you need to eat enough calories from carbohydrates for energy, especially for weight lifting. If you skimp on carbs, you may not have enough stamina to maintain exercise intensity, and your body may turn to muscle for energy. ( 11 )

The protein in Ka’Chava is made up of a plant-protein blend that includes yellow pea protein, whole grain brown rice protein, sacha inchi, amaranth, and quinoa. Varying the plants in a protein supplement creates a more balanced amino acid profile, ensuring you get enough of all the essential amino acids you need to build muscle. In general, plant proteins digest slower than whey protein isolate.

You may even get a boost in absorption when you combine the protein with other health-promoting additives like probiotics and digestive enzymes. ( 4 ) Ka’Chava contains 50 milligrams of prebiotics and probiotics, a proprietary blend consisting of inulin, Lactobacillus rhamnosus , and Lactobacillus acidophilus , plus 50 milligrams of a proprietary blend of digestive enzymes that includes amylase, protease, cellulase, lactase, and lipase.

Nutritionally, Ka’Chava is a superstar, meeting more than 20% of the daily value for many essential nutrients often lacking in a vegan diet, like iron, calcium, and vitamin B12. ( 12 )

However, the ingredients in the vegan shake are proprietary blends, a type of secret recipe that tells us what’s in the powder but not the amounts. Not having all the information about ingredients in a supplement makes it harder to evaluate potency and safety. ( 13 ) Ka’Chava is third-party tested for quality and potency, though.

At $4.66 per serving, Ka’Chava costs more than the standard price of protein powders. But, it’s more nutritionally dense than other protein powders and may replace a whole food meal or snack, saving time and money.

Our product tester reviews were mixed. Some of our testers liked the taste, unique flavor options, and ease of mixing. However, one of our product testers said she’d have a hard time drinking the shake every day.

What customers are saying

Amazon customer reviews for Ka’Chava are mixed. But most people like the quality and flavor of the plant-based protein powder. However, some customers said the supplement was too expensive and didn’t live up to the hype.

Verified Amazon buyer who goes by TulipMadness really enjoyed the Ka’Chava shake. “On first sip it was very forward tasting vanilla. Like drinking vanilla cake batter. Not artificial tasting, not overly sweet. Just good….I’m sitting here afterwards feeling completely satisfied.”

Thomas W. is a verified buyer who bought the coconut acai flavor and writes, “It is filling and occasionally I might add a little blue agave nectar. The only con I have is the pricing of the product. It really is a little pricey.”

Best protein powder for muscle gain for women: Legion Athletics Whey+

Why we like Legion Athletics Whey+ as best for women

Legion Athletics Whey+ has 21–23 grams of protein, 2–6 grams of carbohydrates, 100–130 calories, and 0-3 grams of fat, making it our pick for the best women’s protein powder for muscle gain. Often, women who want to gain muscle to improve muscle tone and definition don’t have to consume as many calories as men.

Research shows that women who want to build muscle and lose fat when working out need to consume at least 20 grams of protein at regular intervals throughout the day, and up to 40 grams. ( 7 ) It’s not just about meeting your daily protein needs, but spacing out your protein so your muscles have a constant supply of amino acids.

In each serving, Legion Whey+ contains 21–23 grams of protein, which is within the recommended amount of protein (20-50 grams) for muscle protein synthesis.

Eating a high-protein diet that supplies enough calories is key for women who want to improve their body composition. If you don’t eat enough protein-rich calories and resistance train, your body may hold on to more fat and you could lose muscle. ( 7 ) Legion Athletics Whey+ is a lower calorie protein supplement, so make sure you’re getting enough calories throughout the day to meet your nutrition needs and goals.

The whey protein isolate powder is all natural without any artificial sweeteners, colors, or flavors, and has no added sugar. It’s also third-party tested for safety and purity.

Legion Athletics Whey+ is a convenient pre-workout protein supplement, and because it’s low in carbs and has very little lactose, it’s easier to digest.

However, Legion’s protein powder is made in a facility that may process common allergens like milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soy. If you have severe food allergies, you may want to consider a different protein powder.

Our product testers tried the dutch chocolate and cinnamon cereal flavors, preferring the chocolate over the cinnamon. Some customers also say Legion’s whey protein powder is too sweet.

At $2.00 a serving, Legion Athletics Whey+ is priced about average for the market. Legion has a subscribe and save program that reduces the retail price by 10%, so you pay $1.80 per serving.

What customers are saying

Shoppers on Amazon give Legion Athletics Whey+ positive reviews. They like the quality, taste, and solubility. However, some buyers find the protein powder too sweet and pricey.

Amazon shopper J. R. purchased the chocolate flavored whey protein powder and wrote, “Superior ingredients make for quick assimilation; good flavor; easy to prepare with shaker bottle; otherwise gets a bit lumpy if it’s only stirred.”

Verified Amazon buyer Carlos was more critical of the protein powder and writes, “Super expensive and doesn’t taste that great. Also only has 22 grams of protein.”

Best muscle gain protein powder for weight loss: Gainful Build Muscle Customized Protein Powder

Why we like Gainful Customized Protein Powder as best for weight loss

When you want to gain muscle and shed some weight, you need to strike the right balance of calories and protein. Gainful Build Muscle Customized Protein Powder may help you strike that balance by creating a personalized powder set to your goals, making it our pick for the best protein powder for both weight loss and muscle gain.

To get your customized protein supplement you take the Gainful quiz on the website, answering a set of questions about goals, fitness routine, and diet preferences. The website uses this information to create your personalized muscle-building, weight-loss protein powder.

Your protein base depends on your diet preferences and options include whey, plant, low lactose, or keto. It’s further customized based on health goals. In our case, build muscle and lose weight.

Nutrition profile for the protein powder varies, ranging from 19–26 grams of protein, 1–3 grams of carbohydrates, 0–6 grams of fat, and 110–140 calories. Again, Gainful works with you to design a protein powder that aligns with your goals and preferences.

A high-protein, energy-restricted diet, when combined with resistance training, promotes fat loss and limits loss of lean muscle. ( 14 )

With a subscription to Gainful, you get access to a registered dietitian who can provide more personalized guidance on macro needs for weight loss and muscle gain.

Another benefit of Gainful is that your customized protein powder includes single-serve flavor boosters. Our product testers liked this feature, giving them an opportunity to try new flavors and even mix flavors.

The customization is a great feature and a major win for Gainful, but it’s costly at $3.21 per serving, which is about $1.00 more than the average price for protein powders. Further, each bag of protein powder has 14 servings, so you need to purchase at least two bags a month for consistency. Another downside of Gainful Customized Protein Powder is that it’s not third-party tested.

What customers are saying

Customers on Trustpilot have mixed reviews for Gainful Customized Protein Powder. Some liked the personalized approach and the quality of the ingredients, while others were disappointed with the customer service.

A Trustpilot customer and verified buyer who goes by the name Gainful Fan liked the results from the protein powder. “I went from being a D-1 athlete (6+ hrs of physical activity a day) to starting veterinary school this year (15+ hours of studying a day, only really having 1.5 hrs to workout). This change made it a struggle to meet my strength goals AND have the mental energy to stay focused all day, UNTIL I started using this brand. My energy levels and recovery are the best they’ve ever been!”

Kristina P. was disappointed with the subscription program and customer service, writing, “I clearly remember looking to try it and selecting one time option. I just got charged for my second order (apparently I chose subscription), no way to reach them to stop the order (phone is constantly busy, chat is not active).”

Best whey protein powder for muscle gain: Sports Research Whey Protein

Why we like Sports Research Whey Protein as best whey

Whey is the main source of protein in many of the supplements on our list. However, with the addition of L-leucine, Sports Research Whey Protein is one of the best whey protein powders for muscle building.

Whey protein is a popular choice for muscle gain because it’s rich in essential amino acids and the branched-chain amino acids (BCAA) that support the muscle-building process. L-leucine is one of the BCAAs, and the amino acid that kicks off and prolongs muscle protein synthesis. ( 1 ) The International Society of Sports Nutrition (ISSN) recommends getting 1–3 grams of L-leucine at every meal when building muscle to stimulate the protein making process. ( 1 )

One serving (1 scoop or 36-41 grams) of Sports Research Whey Protein has 25 grams of high-quality protein and an additional gram of L-leucine. It also contains 2-4 grams of carbs and 4 grams of fat for energy.

The formula uses medium chain triglycerides (MCT) as a source of fat. It’s a popular additive in supplements like protein powders because it digests and absorbs quickly, purportedly to serve as a quick source of energy. However, not everyone tolerates MCT oil, and it may cause gas, bloating, and stomach upset. It may also not provide the energy-boosting benefits as claimed. ( 16 )

The whey protein supplement is an excellent source of vitamin D, meeting 100% of daily needs, and is rich in iron (chocolate flavor) and calcium.

Sports Research Whey Protein is third-party tested and Informed Sport certified, and is free of banned substances, which is particularly important for those who may be drug tested like collegiate or professional athletes.

The protein powder uses non-calorie sweeteners sucralose and acesulfame potassium (Ace-K) to add flavor without carbs. Though generally recognized as safe, some people may experience side effects from the sweeteners, like stomach upset or headaches. ( 17 ) Limiting your intake of artificial ingredients like these sweeteners is recommended for overall health.

Sports Research Whey Protein is one of the most affordable protein powders on our list at $1.03 per serving, priced about $0.80 less than average.

What customers are saying

Shoppers on Amazon like the nutrition, taste, and value of Sports Research Whey Protein Powder. However, some customers report stomach issues after drinking the shake.

Cole is an Amazon customer who purchased the chocolate flavor whey protein powder. “Best value for protein powder i’ve found and great quality/taste!”

Zulema F. is a verified Amazon shopper who didn’t tolerate the protein shake. “I was very excited to try this product, I actually ordered the creamy vanilla and chocolate and they are both great tasting, but there is something in them that makes me sick, I get a really bad upset stomach, nausea and it does make me sleepy and tired.”

Best organic protein powder for muscle gain: Nutricost Organic Whey Protein

Why we like Nutricost Organic Whey Protein Powder as best organic

Nutricost Organic Whey Protein Powder contains USDA-certified 100% organic whey concentrate and is our pick for the best organic protein powder for muscle gain. The one scoop serving size (25-36 grams) has 20 grams of protein, less than 1-10 grams of carbohydrates, 2-3 grams of fat, and 100-150 calories.

In addition to organic certifications, we like Nutricost’s protein powder because of its short ingredient list, which includes organic whey protein concentrate that consists of organic whey protein with organic sunflower lecithin, an emulsifier to help with mixability. ( 18 )

The nutrition profile of Nutricost Organic Whey Protein Powder makes it a good choice for anyone in need of more protein to maintain body weight or build muscle.

The organic whey protein powder is third-party tested for quality and potency and made in a good manufacturing practice (GMP) compliant facility, one of the Food and Drug Administration’s safety protocols for supplements. ( 19 )

Nutricost Organic Whey Protein Powder is gluten-free and vegetarian-friendly, but it isn’t vegan or dairy-free. With 1-10 grams of carbohydrates per serving, this whey protein has very little lactose, making it easier to digest and less likely to cause unwanted side effects like gas and bloating.

At $1.32 per serving, Nutricost Organic Whey Protein Powder is a good value, priced a lot lower than the standard market price. It’s a clean, high-quality protein powder that provides the nutrition you need to gain muscle, without added ingredients.

One of the drawbacks of the protein powder is that you only have three options for flavor: chocolate, vanilla, and unflavored.

Directions suggest mixing the powder with water, but any liquid works. You can use milk or a plant milk as your liquid and create your own flavor with fruit, sweet spices like cinnamon, or a nut butter. Or, mix the chocolate-flavored powder with milk to create a high-protein chocolate milk for post-workout recovery.

Despite its many positive qualities, the protein powder isn’t a good fit if you don’t like the taste or texture, which is the case for some of the critical customer reviews. Difficulty mixing is another common complaint.

What customers are saying

Reviews for Nutricost Organic Whey Protein powder are mixed from customers on Amazon. Some like the simplicity and quality of the protein powder, while others have a hard time mixing the powder.

Mohammed T. is a verified Amazon customer who writes, “Great tasting organic whey protein. When blending in a vitamix to make a smoothie, the organic whey will stick to the side of the blender and it needs to be scraped back into the mixture… The powder blends well with liquids and there’s no clumps when using a blender. Tastes great and lots of protein.”

Another verified Amazon Mayra writes, “Does not dissolve in cold water at all as stated on the container.”

Best protein powder for weight gain: Transparent Labs Mass Gainer

Why we like Transparent Labs Mass Gainer as best for weight gain

Transparent Labs Mass Gainer is a solid supplement for individuals wanting to gain weight without consuming unnecessary substances and artificial ingredients. With a clean macronutrient profile, disclosure of exact dosages of each ingredient, and a pleasant taste, it was an easy pick for the best protein powder for weight gain.

Each Transparent Labs Mass Gainer serving includes 51-53 grams of protein, 106-110 grams of carbohydrates, 13-14 grams of fat, and 730-750 calories. Therefore, if you’re a hard gainer finding it challenging to meet your caloric needs using food alone or an athlete wanting to aid the post-workout recovery process, this should help.

Research suggests you should double the RDA for protein, which is 1.4-2.0 g/kg of body weight, if you hope to gain muscle. ( 1 ) Even during the off-season, some male bodybuilders consume up to 4.3 g/kg of protein per day, and females up to 2.8 g/kg. ( 20 ) The aim is to take in 25% to 30% of their energy from protein, so most athletes should strive for about 2.2 g/kg to achieve an optimized response. ( 20 )

The Transparent Labs Mass Gainer provides a hefty amount of complete protein sourced from grass-fed whey concentrate, which may help individuals achieve their weight and muscle gain goals.

Most mass gainers have a 2:1 ratio of carbs to protein, and that’s the case here too. The carbs in this formula primarily come from organic tapioca maltodextrin. Since this ingredient isn’t sourced from corn or wheat and is naturally gluten-free, many athletes prefer it. Oat flour and sweet potato powder are included as well. It’s claimed that all of these ingredients are easier to digest.

However, if you have diabetes or any form of insulin resistance, this might not be the best product for you. Maltodextrin has a higher glycemic index than sugar and may increase one’s blood glucose shortly after consumption.

There are also 4-6 grams of fiber, and a good amount of it is prebiotic. Prebiotics and probiotics may help maintain a strong microbiome and support healthy digestion. ( 21 )

Carbs, in general, are said to improve strength and body composition. ( 11 ) Research also states that carbohydrates may decrease muscle damage brought on by endurance exercises. ( 22 )

The fats are sourced from MCT oil and coconut milk, which are considered healthy fats. MCT oil digests quickly, but it can cause undesirable gastrointestinal issues, like gas and bloating, in some people ( 16 ). Also, because this has a high saturated fat count, those with heart issues may want to consider another product.

The Mass Gainer formula contains a significant amount of calories, so it should help you achieve a caloric surplus.

You’ll also find 3 grams of creatine on the ingredient list, which is an evidence-based dose. ( 23 ) Many who exercise often like to supplement creatine as it’s shown to help enhance muscle mass, recovery, and performance. ( 24 )

Overall, there’s much to like about Transparent Labs Mass Gainer. It’s third-party tested, and the company even shows their Certificate of Analysis from Dyad Labs. It also boasts the Informed Choice quality mark, meaning it’s been evaluated for banned substances and should be suitable for athletes.

This product only comes in two flavors, which is very limited, but at least they’re good. One of our product testers tried the chocolate glazed donut flavor and said it was delicious and really tasted like a donut.

To use, mix two scoops in 16 ounces of water or milk. You can also add it to a shake. Our product tester said it has excellent solubility, as it dissolved well, provided a good consistency, and didn’t have any clumps.

This is considered a higher-end supplement, and the price reflects that. One serving of Transparent Labs Mass Gainer is $5.33, and only 15 servings are available in the box. Therefore, if you plan to use this product daily, purchase two containers monthly and factor in the cost.

Best natural protein powder for muscle gain: Promix Unflavored Vegan Protein Powder

Why we like Promix Unflavored Vegan Protein Powder as best natural

Those looking for a supplement free of artificial ingredients, with a completely all-natural formula, should consider Promix Unflavored Vegan Protein Powder. We believe this is the best natural protein powder for muscle gain because it contains top-quality ingredients sourced primarily from North America that undergo traceable testing.

A glance at the supplement facts label will show you that Promix Unflavored Vegan Protein Powder contains 25 grams of protein, 2 grams of carbs, 0 grams of fat, and 115 calories per serving. It’s ideal for individuals trying to build muscle who want a supplement to aid the recovery process.

The ingredients list is short, containing only Canadian yellow pea protein isolate and vitamin B12. The yellow peas are sourced from Canadian farms and are an excellent choice for those who want a plant-based option without allergens.

This pea protein contains all nine essential amino acids and 5.2 grams of branched-chain amino acids. However, one flaw of plant-based protein is that it contains significantly less methionine than whey protein. ( 25 ) Methionine is an essential amino acid that your body cannot make on its own, and is thought to aid with digestive functioning and modulating metabolism. ( 26 ) Therefore, in order to get enough of it, you may need to get it from other foods in your diet, such as sunflower seeds, quinoa, and oats.

Nonetheless, pea protein is a solid sourse of arginine, leucine, and other amino acids. Evidence suggests that arginine supports heart health and leucine aids with the muscle-building process by triggering and prolonging muscle protein synthesis. ( 27 ) ( 1 )

The micronutrients found in this protein powder are calcium, iron, potassium, and B12. Vegan diets are often associated with calcium, potassium, and vitamin B12 deficiencies, so it’s nice to see those included here, though some are in small amounts. ( 12 ) Calcium makes up 10% of the daily value in this formula, and potassium only 3%. But B12 shines here, providing 200% of the daily value—which exceeds the daily requirement but is still considered safe since it’s a water-soluble vitamin.

Those trying to limit sugar will appreciate that there are 0 grams here. The sodium content isn’t excessive, either, with 110 milligrams per serving at only 5% of the daily value.

We like that each product batch undergoes traceable testing and that Promix keeps formulation and design in-house. Their Unflavored Vegan Protein Powder is made in facilities using GMP (Good Manufacturing Practice) standards, and the packaging reportedly contains 67% less carbon than similarly sized products.

There are various ways to consume this protein powder. Some people add it to shakes and smoothie bowls, but you can also bake with it or add it to oatmeal. For shakes and smoothie bowls, add two scoops to 12-16 ounces of cold water, milk, or juice.

You can purchase either a 2.5-pound or 5-pound package. The larger one contains 78 servings and is priced at $0.88 per serving, which is very affordable. Even the 2.5-pound container with 38 servings is priced well at $1.16 per serving. You can’t go wrong either way.

If you’re looking for a protein powder free of soy, gum, hormones, antibiotics, gluten, fillers, GMOs, and all artificial ingredients, this is one of the best.

What customers are saying

Promix Unflavored Vegan Protein receives mostly positive reviews on Amazon, but a few people don’t like the taste and/or texture.

One Amazon customer, tidalwayfarers, said this was the best vegan protein powder available. They went on to say, “The taste is very mild, the texture is nice and creamy, mixes easier than any other I have tried, no bitter aftertaste, no graininess, not cloyingly sweet, or unnecessarily salty, no sugar, gives you plenty of iron, and 72 servings is a good value.” However, their one critique was the packaging, which they thought was subpar.

However, another Amazon customer, Mountainheart Endurance, found the powder clumpy when used in shakes. “I loved the flavor—not too sweet and clean. For the quality of ingredients, I even felt like the price was fair. I did not love the consistency. In the blender, it was fine, kind of foamy, but in a shaker jar, rather clumpy. Would I buy it again, with no soy or gluten? Probably yes!”

Best protein powder for diabetics to gain muscle: Cymbiotika Plant Protein

Why we like Cymbiotika Plant Protein as best for diabetics to gain muscle

If you have diabetes, there are certain precautions you want to take when using protein powder. High glycemic sugars and carbohydrates can spike your insulin levels, which isn’t what you want to do along your fitness journey. Fortunately, dietary supplements like Cymbiotika Plant Protein have ingredients that may align with this group’s health needs, which is why we consider it the best option for diabetics to gain muscle.

This green powder is gluten- and soy-free, keto-friendly, and made in GMP-certified facilities.

Cymbiotika Plant Protein only contains 10 grams of carbs per serving. As a result, this supplement should be satisfactory for those with diabetes as long as they don’t exceed the recommended amount of carbs. If you’re following a low-carb diet, you should consume less than 130 grams of carbs daily. ( 29 ) Some evidence shows that ketogenic (very low-carb) diets may improve HbA1c levels in just three weeks in type 2 diabetics. ( 28 ) That’s because the lower intake of carbohydrates may help decrease significant fluctuations in blood sugar.

The supplement facts label lists 5 grams of fiber sourced from the Baobab tree (a.k.a. “Tree of Life”). This type of carb aids with blood sugar regulation and weight management . Plus, it breaks down slowly, which not only helps you feel full longer but also gives your body more time to absorb the macronutrients provided. Research even suggests that high dietary fiber intake is associated with increased skeletal muscle mass, so this protein powder, along with fiber-rich foods, may help you achieve that. ( 30 )

The Cymbiotika Plant Protein formula contains 20 grams per serving of three complete proteins: hemp, spirulina, and peas. Spirulina, specifically, has been observed to aid fasting blood glucose and blood lipid levels. ( 31 ) Therefore, researchers believe that it could prove helpful when combined with conventional medicine for those with type 2 diabetes. One study showed that spirulina supplementation may stave off exercise-induced lipid peroxidation, inflammation, and skeletal muscle damage. ( 32 )

This unique protein blend provides several essential nutrients and contains 100% of the daily value for vitamins E and K. It also contains prebiotics and probiotics, raw greens, digestive enzymes, and adaptogenic mushrooms.

With organic ingredients and an impressive amino acid profile that may enhance muscle and total-body protein synthesis, Cymbiotika Plant Protein is a respectable choice. ( 33 ) It’s said to be free of preservatives, chemicals, additives, and alcohols. However, we could not identify whether it has undergone third-party testing for banned substances, which impacts our rating.

A single scoop equals one serving, and there are 24 in the $88 package. Therefore, it’s one of the higher-priced options on the market, costing $3.67 per serving. This supplement can be taken any time of day, but some may prefer to consume it post-workout for improved muscle recovery. Just add a scoop to 8-10 ounces of cold water, a smoothie, or milk.

What customers are saying

Most of the reviews for the Cymbiotika Plant Protein powder on Amazon were positive. For instance, Amazon customer Manfred Moore divulged that they loved the ingredients but felt like the price was hefty.

One verified purchaser, who didn’t disclose their name, indicated that this is an amazing product with great taste.

Julia Redin is an Amazon customer who felt it wasn’t worth the price: “I wanted to like this, but I believe that it isn’t worth the price point. For that price, I would hope for USDA organic certification and also more than just 200mg of greens. The taste could be improved with perhaps more vanilla or monk fruit instead of stevia.”

Best protein powder for muscle gain for beginners: Jacked Factory Authentic Iso

Why we like Jacked Factory Authentic Iso as best for beginners

If you’re new to using protein powder, you’re probably still trying to figure out what you like and don’t want to spend too much money in the process. Maybe your focus is simply on boosting protein intake so you can hopefully achieve muscle gains and support post-workout recovery. If such is the case, we consider the Jacked Factory Authentic Iso protein supplement to be a solid choice.

It was easy to give the Jacked Factory Authentic Iso a 5 out of 5 for formulation because it has a good ratio of protein to carbohydrates and fats. For example, the vanilla flavor provides 25 grams of protein, 1 gram of carbohydrates, 0.5 grams of fat, and just 110 calories per serving. Therefore, this is a good option if you’re on a low-calorie diet and want to increase your protein intake but avoid added sugars.

Jacked Factory uses grass-fed whey protein isolate, which tends to be easier to mix and digest. The “isolate” means it’s undergone extra processing to remove additional cholesterol, lactose, and fat, to create a purer source of protein.

Whey protein is also considered a complete protein, meaning it includes all nine essential amino acids that the body needs but can’t produce on its own. It’s also rich in BCAAs, which help with muscle recovery and growth.

In addition to whey protein, this product contains Himalayan rock salt, sucralose, and 10 milligrams of stevia. Both stevia and sucralose are calorie-free sweeteners, but sucralose may cause unwanted side effects in some, like headaches and gastrointestinal concerns. ( 17 ) Stevia may have a bitter, metallic flavor that some people find unpleasant.

If you’re getting most of your micronutrients from meals, then the lack of them here shouldn’t be a big deal. It contains just 94 milligrams of calcium and 98 milligrams of potassium, which both make up less than 10% of the recommended daily value.

According to their claim, this supplement is manufactured using state-of-the-art filtration processes, producing a very pure protein source. However, as good as that and their transparent labeling are, we don’t like the lack of third-party testing for banned substances.

Jacked Factory Authentic Iso comes in nine flavors, including unflavored, cookies and cream, and vanilla oatmeal cookie. Our product tester tried the vanilla flavor and said it was decent but a bit too sweet. In terms of solubility, we found that it mixed well and had very few clumps after shaking it up.

Overall, Jacked Factory Authentic Iso is a suitable choice for beginners who want to primarily boost their protein intake and have different flavors to try in the process. Plus, it’s affordable at $1.33 per serving, especially compared to other protein powders on the market.

What customers are saying

Customers on Amazon have mainly positive reviews on Jacked Factory Authentic Iso, especially regarding mixing, taste, and value. However, some mentioned having digestive issues.

Amazon purchaser Nick G stated, “I have been looking for a new protein powder, specifically whey isolate (concentrate upsets my stomach). I love peanut butter, so I gave this one a try. The taste is very good (almost like a peanut butter caramel). It is absorbed/digested. It mixes well. Good/fair price.” Besides being a little too sweet due to the sucralose, they said it will be their go-to for a while.

Craig Mankiewicz felt like this would be a great product for him, but experienced GI symptoms after consuming it. “I was using another brand of whey protein isolate, but they were out of stock, so I thought I would try Jacked Factory. The product mixes fine, tastes great, and is priced right. However, ever since I started using it, I have experienced major gas and bloating symptoms. I stopped taking it for a few days, and now I feel fine, so it’s definitely the product.”

How to choose the best protein powder for muscle gain

Choosing the best protein powder for muscle gain depends on multiple factors, like your goals, exercise routine, and personal preferences. Consider the following when looking for a protein powder to support muscle growth:

Protein source

One of the first things to consider is whether you want an animal-based or plant-based protein. Both types provide the complete protein you need for muscle gain and the one best suited for you depends on your food preferences as well as food allergies and sensitivities.

Animal-based proteins include whey and casein, while plant-based proteins include pea, soy, brown rice, and plant blends (pea and brown rice), among others.

Health needs and fitness goals

Your personal health needs and fitness goals also determine the best protein powder for you. A protein supplement that provides all the essential amino acids, especially leucine, necessary for muscle protein synthesis is key. But the makeup of your supplement choice may depend on whether you want to lose or maintain body weight or gain muscle.

Nutrition profile

Nutrition profile ties into your health needs and fitness goals. Carefully examine the supplements nutrition facts label. A good protein powder for muscle gain should provide 20 to 40 grams of high-quality protein per serving. ( 1 )

Protein powders usually have some carbs and fat. The amount of carbs, fat, and protein in the supplement affects total calories. Choose protein powder that supplies the nutrition you need to meet your goals.

List of ingredients

Protein powders may contain additional ingredients beyond your preferred protein. It’s important to look at this list to check for sweeteners like stevia and sucralose, additives such as fiber and digestive enzymes, and other ingredients like glutamine and creatine.

The added ingredients may affect taste, tolerance,and effectiveness.

The list of ingredients may also include fillers, preservatives, or artificial flavors. It’s always best to choose protein powders with fewer ingredients to reduce risk of unwanted side effects like stomach upset or allergic reactions.

Safety

Look for protein powders that are third-party tested, meaning the supplement was evaluated by an independent lab for quality and purity. Supplements may display testing information on their website or the label.

Cost

Protein powders come in a range for prices. When selecting the best protein powder for muscle gain, you want one that fits your budget and supports your goals.

Taste

Consistency is the key to meeting health goals. If protein powder provides the nutrition boost you need to build muscle, then you need to consistently use it. If you don’t like the taste or texture of your protein shake, you won’t get the benefits.

How much protein do I need a day to build muscle?

The amount of protein you need a day to build muscle depends on your physique, workout routine, and ultimate goals. The ISSN says you need to eat enough protein to create a positive nitrogen balance. ( 1 ) This means you have an adequate supply of essential amino acids to meet general needs and then a little more to build muscle.

Body weight is used to estimate individual protein needs, and for those who are trying to build or maintain muscle the recommendation is about double the RDA, or 1.2-2.0 g/kg of body weight. ( 1 )

If you need help figuring out your daily protein needs, schedule a consultation with a registered dietitian for personalized guidance.
