Fact Checked by Kelly Uhler
For this review, we tested every protein supplement from Legion Athletics, assessing key factors like calorie and macronutrient profiles, ingredient quality, and taste across multiple flavor options. We also compared each product’s cost to the competition, verified third-party testing for quality assurance, and evaluated the overall customer experience, including purchasing and customer service interactions with the company.
We asked Chris Mohr, PhD, RD and Victoria Burgess, PhD, CSCS, CISSN, two renowned sports nutritionists, for their insights on what makes protein products effective. Lily Moe and Jessica Coulon, two seasoned nutrition editors, also provided their review. Lastly, Kelly Uhler conducted fact checking to ensure total accuracy.
When it comes to choosing the right protein powder or supplement to support your health and fitness goals, factors like ingredient quality, taste, and nutritional value are a top priority. However, with so many different products on the market, it can be challenging to find a brand you trust that consistently delivers on all fronts. That’s where Legion Athletics comes in—a company that has earned a reputation for its all-natural ingredients and science-backed formulas.
In this review, our team of health and fitness experts takes a comprehensive look at Legion Athletics’ entire protein supplement lineup, from their highly rated Whey+ and Plant+ protein powders to their protein bars and cookies. Whether you’re aiming to build muscle, enhance recovery, or simply boost your daily protein intake, Legion Athletics offers a range of products that may meet your specific needs.
Legion Whey+ is a premium grass-fed whey protein isolate powder that steers clear of artificial sweeteners, flavors, and colors. With only 100 to 130 calories per serving, it delivers 22 grams of protein and is available in over 18 flavors, catering to a wide range of taste preferences.
Legion Athletics Whey+ is a grass-fed whey protein isolate powder that caters to a wide range of individuals, from athletes aiming to enhance their performance to individuals pursuing weight loss goals. One of the standout features of this product is its impressive nutritional profile. Each serving is low in calories, varying between 100 to 130 calories depending on the flavor, while still packing in 22 grams of high-quality protein. This makes Whey+ an excellent choice for those who want to maximize protein intake without adding unnecessary calories to their diet.
“For those who don’t mind any extra calories but want to stay away from artificial sweeteners, this lower calorie powder allows users to add fruits or other sugar sources to sweeten up the blend,” notes Victoria Burgess, PhD, CSCS, CISSN.
For athletes, especially those engaged in resistance training, protein is essential for muscle repair and growth. ( 1 ) The 22 grams of protein per serving in Legion Whey+ provides a significant amount of the amino acid building blocks needed to support muscle growth and recovery. “This 22g of protein is the ideal amount post workout for muscle protein synthesis,” adds Burgess.
Additionally, the low calorie content allows athletes to increase their protein intake without compromising their overall caloric balance, making it easier to maintain or build lean muscle mass while managing body fat. Based on this lean macronutrient profile, Legion Whey+ is one of the best protein powders for anyone looking to increase their protein intake without unwanted weight gain.
For individuals with weight loss goals, Legion Whey+ is an equally valuable tool. Protein is known for its satiating effects, helping to curb hunger and reduce overall calorie intake. ( 2 ) “It also has a high thermogenic effect,” notes Burgess, “which means you burn lots of calories by just simply digesting protein.” By incorporating a low-calorie, high-protein supplement like Whey+ into their diet, individuals can feel fuller for longer, making it easier to adhere to a calorie deficit necessary for weight loss. ( 3 ) The low calorie content ensures that users can enjoy the benefits of a protein supplement without derailing their progress.
Alongside the protein, Whey+ also includes natural flavors, xanthan gum, sunflower lecithin, salt, and stevia leaf extract. The natural flavors, stevia, and salt enhance the taste, while xanthan gum and sunflower lecithin act as emulsifiers, helping the protein powder mix seamlessly into liquids for a smooth, consistent texture. Whey+ is also third-party tested for quality and safety.
Legion Whey+ is one of my go-to protein powders. I’ve tried the Dutch chocolate, peanut butter fudge, and cinnamon cereal flavors, and each one has been delicious without being overly sweet. The powder also mixes effortlessly in a traditional blender bottle, making it convenient for any time of day.
Whey+ has an average rating of 4.3 out of 5 stars on Amazon, from over 5,300 reviews. Amazon customers appreciate the variety of flavors available with Whey+, often praising both the taste and smooth consistency of the product.
“So I am trying the Legion brand for the first time based on a friend’s recommendation and I really like this whey protein. Mixes really well in a shaker bottle, isn’t gritty and actually tastes like the Cinnamon Toast Crunch cereal! I mix with almond milk and it is perfect for breakfast or an afternoon snack.”
Despite purchasing on Amazon, Liz J. had a great experience with Legion’s customer service team. “I contacted Legion since Amazon won’t handle refunds/returns for this item. Legion responded immediately and offered to send me a different flavor. I am extremely impressed with their customer service, so I updated the stars from 3 to 4. Just stay away from the banana bread flavor unless you like banana Laffy Taffy + cinnamon.”
Sheryl S. says she uses Legion Whey+ to make delicious ice cream using her Ninja CREAMi. “No funny after taste. Works great for ice cream in Ninja. Love the flavor, keeps calories low and protein high.”
Legion Plant+ is a vegan protein powder that provides approximately 25 grams of plant-based protein sourced from a mix of pea protein isolate and rice protein concentrate. Staying true to their quality standards, Legion Athletics uses all-natural, non-GMO ingredients, sweetening their product with a blend of stevia leaf extract and monk fruit.
For those adhering to a vegan or dairy-free diet, Legion Plant+ offers an excellent alternative to whey-based protein powders.
Many plant-based protein powders fall short because they lack a complete amino acid profile, meaning they don’t provide all nine of the essential amino acids needed to build and maintain lean muscle mass. ( 4 ) However, Legion Plant+ addresses this issue by combining pea protein isolate with brown rice protein concentrate. This protein blend ensures a full spectrum of essential amino acids, mirroring the benefits of whey protein as a viable alternative. ( 5 )
Furthermore, Legion’s commitment to using all-natural, non-GMO ingredients further enhances the appeal of Plant+. The company intentionally avoids refined sugars and non-nutritive sweeteners like sucrose, dextrose, sucralose, or acesulfame potassium, opting instead for natural sweeteners like stevia leaf and monk fruit extract. This approach aligns with the brand’s health-conscious ethos, ensuring Plant+ remains free from artificial additives.
When it comes to flavors, Plant+ offers six options, including classics like Dutch chocolate and French vanilla, along with more adventurous choices like cinnamon cereal, salted caramel, and apple pie. I’ve personally tried the Dutch chocolate and apple pie flavors, and found they tasted far better than other plant-based protein powders I’ve sampled in the past. They lacked the typical chalky or earthy taste and avoided the overly thick consistency that’s often associated with plant-based protein powders. The mixability is also top-notch, which is nice for when you don’t have a blender on hand.
“This can be really useful post workout, as consuming protein within the first hour after working out is ideal for muscle protein synthesis. Therefore, shaking with milk or even just water is a quick way to get down a post workout drink that tastes good.”
Victoria Burgess, PhD ,CSCS, CISSN, Fortune Recommends Advisor
The one drawback of this Legion supplement is that it offers just 20 servings per container, compared to the 30 servings provided in Legion’s Whey+ and Casein+. This bumps up the price to $2.50 per serving, making it a bit more of an investment for those committed to a plant-based protein powder. However, you can save 10% by subscribing. For the quality, taste, and mixability it delivers, you may find it worth the price.
Legion’s Plant+ holds a 4 out of 5 star average rating on Amazon from 474 reviews, with customers commenting favorably on the taste, mixability, and protein content on the product.
“Okay—I can’t even begin to compare the quality and taste of Legion’s Plant Protein! I have tried many, many I mean manyyyyy vegan protein powders and have found one of two things: 1. Great flavor but filled with so much junk, of course it tastes good 2. Incredibly chalky and just nasty flavor and not enough protein. Legion Plant Protein has blown me away! My top two flavors are chocolate, mocha and okay actually, cinnamon too! The ingredients are definitely quality and have never upset my stomach and I suffer GI issues.”
In another review from verified buyer Johnny B., he shares that his wife was thrilled with the Apple Pie flavor. “I bought Plant+ for my wife, and she said it’s the best plant-based protein she’s ever had. The flavor is incredible—just like a slice of apple pie. It’s smooth, mixes well, and doesn’t have that gritty texture you often find in plant-based proteins.”
A review from Amazon user Meg mentions the flavors can be hit or miss. “I love Legions plant based protein powder salted caramel but I tried mocha cappuccino. Don’t get it waste of money not a good flavor something is off…”
Casein+ is a slow-digesting protein powder designed to deliver a sustained release of amino acids during extended periods without food, making it well suited for long work shifts or overnight recovery.
Casein, which is the protein found in Legion Athletics Casein+, is renowned for its unique slow-digesting qualities, making it an ideal choice for supporting muscle growth and recovery during extended periods without food, such as overnight. ( 9 ) While not everyone may require a casein protein powder , athletes and bodybuilders in particular can benefit from its potential advantages.
Casein is an animal-based protein supplement and the primary protein found in milk. In fact, casein makes up around 80% of the protein in cow’s milk, with the remaining 20% coming from whey. ( 6 ) While both casein and whey proteins share similar macronutrient profiles, they differ significantly in their rates of digestion. This is due to casein’s unique property of forming a gel-like substance in the stomach, which gradually releases amino acids to be absorbed by the body inside the small intestine. ( 7 )
This slow breakdown process allows casein to provide a continuous supply of amino acids into the bloodstream, supporting prolonged muscle protein synthesis, which is the process by which muscle tissue is built and repaired. ( 8 ) For athletes and bodybuilders, who often engage in rigorous strength training and heavy weightlifting, this continuous supply is crucial for maximizing muscle development and recovery, and is often consumed prior to sleep. The one thing to make note of, is that protein can sometimes increase body temperature during digestion, which can affect sleep quality in some.
In addition to its effective slow-digesting properties, Casein+ is appreciated for its high-quality ingredients and excellent taste. The cinnamon cereal flavor has become a staple in my nightly routine and easily satisfies my sweet tooth cravings before bed.
Each serving provides approximately 25 grams of protein with a creamy texture (especially when using milk) that mixes well, although I would suggest using a blender for this supplement as it is much thicker than a traditional whey. While the thicker consistency may take some getting used to, it does contribute to a more satisfying and substantial shake that helps support muscle recovery throughout the night.
Casein+ costs the same as Legion’s Whey+, at $2.00 per serving. It offers great value considering that casein protein powders are typically more expensive than whey.
Rated 4.1 out of 5 stars from over 1,000 reviews, Amazon customers like the overall quality and satiation Casein+ provides.
“Minor quibbles: this powder is really fine and can easily go *poof* and make a mess while you’re scooping. The flavor is rather light and I wish it had a little more oomph of banana-ness. Other than that, it’s tasty, has a really nice smooth & creamy texture, mixes well, and has a great protein for calories ratio. On the pricier side, but I find this to be of an excellent quality, and it justifies the price for me.”
Richard B. leaves another helpful tip, noting you should avoid premixing your casein protein shakes. “Just a tip. Don’t premix your shakes and leave them in the fridge for later. It will become so thick and foamy that you literally can’t drink it. The way to use this casein is to mix the shake and drink it right away. At that point, it is still a liquid and actually tastes pretty good. Leave it for a few hours and it turns into almost a solid.”
Monique S. tried the Dutch chocolate flavor, saying, “I like the regular Legion protein better, this one has a different taste and leaves a film in your mouth. The macros are great just not the taste.”
While marketed as a “protein” bar, this product also packs in 250 calories per serving—roughly double the calories in a Legion Whey+ protein shake. This higher calorie count positions Legion Protein Bars more as a meal replacement option than a typical protein bar supplement.
Depending on what you’re looking for, Legion Protein Bars may or may not be the right fit for you. The key consideration with these bars is that they function more as a meal replacement option than a traditional protein bar, given their balanced macronutrient profile and higher calorie count.
With around 250 calories per bar, Legion’s Protein Bars contain more carbohydrates than protein, making them a better fit for those who need sustained energy rather than a low-calorie protein supplement. While this isn’t necessarily a drawback depending on your goals, these bars might not be the best choice if you’re following a weight loss program or cutting after a bulk. However, if you’re looking for a convenient snack between meals that can help sustain you, or some on-the-go post-workout recovery, these bars can be an excellent fit, giving you a great mix of protein, fat and carbs.
One of my favorite features of the Legion Protein Bars is their higher dietary fiber content, which isn’t common in a conventional protein bar. Each bar contains six to nine grams of prebiotic fiber from chicory root, which is not only beneficial for gut health but also supports digestion. ( 11 ) Fiber also plays a crucial role in maintaining steady energy levels and promoting a feeling of fullness, making it a potential tool for those managing their weight or trying to control cravings and hunger levels throughout the day. ( 10 ) In a time when many people fall short of their daily fiber intake, this addition is a welcome benefit.
“Fiber is really an unsung hero in the nutrition world, with data suggesting most get way less than is recommended. While fruits, vegetables, legumes and a wide variety of different grains could provide the recommended 25-38 grams daily for women and men, respectively, most don’t eat the variety of those foods needed. And that’s where the complement of a fiber rich bar or similar product can be useful.
Chris Mohr, PhD, RD, Fortune Recommends Advisor
Regarding the flavors, I’ve tried both the chocolate chip cookie dough and chocolate peanut butter varieties. While they don’t taste exactly like real cookie dough or a chocolate peanut butter candy bar, they’re not meant to, and they’re still quite tasty for protein bars.
The texture, however, is hard to miss. These bars are incredibly dense and can be pretty firm. I recommend keeping them at room temperature, and if you find them too hard, try microwaving them for a few seconds (after you take them out of the wrapper). This softens the texture significantly, making them much more enjoyable to eat.
These bars are on the pricier side compared to Legion’s protein powders, at $3.33 per bar. However, you may find the convenience and macronutrient profile worth the price.
Amazon customers have rated Legion Protein Bars a solid 4 out of 5 stars from over 320 reviews, noting the taste, texture, and protein content as key reasons for their reviews.
“As a fitness coach I’m always looking for high quality protein bars for myself and for my clients. Not only do these taste amazing they also have high quality ingredients which I can’t say about many of the others I’ve tried! They are a bit harder to chew compared to others however I keep mine in the trunk of my car for clients and for when I’m on the go so the heat makes them much softer and easier to chew. They also don’t make a mess which is super nice! Highly recommend you give these a try!”
An Amazon customer with the username “Seeyouinthetrees” tried the chocolate peanut butter flavor and commented on the dense texture of the Legion Protein Bars.
“It’s true—as so many others report—the bars have not expired, yet they are so hard it is difficult to bite through them. The maker should do something about this and they should pull the bars that are already made this hard and try to re-formulate. Otherwise—it is a GOOD QUALITY line of protein bars—just wish they would listen to their consumers and do the right thing. As far as the ‘Chocolate Peanut Butter’ flavor, as in most cases with this flavor of protein bars, you taste ONLY chocolate and not peanut butter.”
Verified buyer Caroline shares her experience with the chocolate chip cookie dough flavor. “I never reach for protein bars because so many of them are full of ingredients I don’t like/trust. But when I saw Legion was now carrying bars I HAD to check them out! And just as I suspected, a reason I LOVE this company, it doesn’t rely on trash ingredients to make a good product. They’re so yummy too! I’m a chocolate chip cookie girlie so that’s what I ordered and I’m not disappointed in the slightest. Thanks for continuing to be a company we can reach for and know every ingredient is backed by science!”
Legion Chocolate Chip High Protein Cookies offer a tasty way to satisfy your sweet tooth while packing in a substantial amount of protein, 15 grams. In addition to their protein content, these cookies also help boost your fiber intake, offering nine grams of dietary fiber from chicory root in each cookie.
Legion Athletics Protein Cookies offer a nutritious way to satisfy your sweet tooth while also meeting your dietary goals. What sets these cookies apart is their combination of great taste and significant nutritional benefits. Each cookie delivers 15 grams of protein, making it an excellent choice for anyone looking to increase their protein intake while enjoying a treat.
Remember that these protein cookies aren’t just a tasty dessert alternative, they also serve as a practical option for fueling your workout or aiding in post-workout recovery. With a balanced macronutrient profile of 8 grams of fat, 15 grams of protein, and 32 grams of carbohydrates per cookie, they provide a well-rounded energy boost. The combination of protein and carbs supports muscle repair and helps replenish glycogen stores, making them an excellent choice for active individuals needing a convenient and nutritious snack. ( 13 ) With their high fiber content, these cookies wouldn’t be the best pre workout, but fit the bill for after a workout or maybe for an evening conscious indulgence if you want a little protein boost and also a sweet treat.
Similar to Legion Protein Bars, Legion Cookies also contain a significant amount of dietary fiber. With nine grams of fiber per cookie, they make a substantial contribution toward meeting your recommended daily fiber intake. For context, the recommended amount of daily fiber is 38 grams for men and 25 grams for women. ( 12 ) By enjoying one of these cookies and pairing it with a piece of fruit, such as an apple or banana, you’re well on your way to reaching your daily fiber goal.
The consistency of these cookies is also worth noting—they’re soft, chewy, and full of flavor. Unlike many protein bars and cookies that can be dense and hard, these cookies offer a pleasant contrast and can be a great way to enjoy a snack that doesn’t compromise on nutrition.
Like Legion’s protein bars, these cookies also cost $3.33 each. Currently, Legion only has the chocolate chip flavor available, but we hope they expand their offerings in the future. Additional flavors could make this product more accessible, especially for those who are unable to enjoy it due to its inclusion of tree nuts in the form of almonds, a common allergen.
Amazon customers appreciate Legion’s Protein Cookies for their appealing taste and well-balanced macronutrient profile, giving them an average rating of 4.1 stars from 77 ratings. Reviews also highlight the cookies chewy texture and satisfying consistency, noting they serve as an excellent choice for meal prep or a healthy dessert to curb cravings.
“ These cookies are incredible.15 grams of protein, 9g of fiber, and a perfect on-the-go snack before/after workouts, or just to hit your daily macros. Love the flavor, can’t say enough about these cookies.”
Johnny B. also praises the consistency, saying, “The texture is spot on—soft and chewy—and the taste is better than any other protein cookie I’ve tried. Even better after a few seconds in the microwave! A delicious way to hit your protein goals without feeling guilty.”
Adam P. also left a review and said, “I really like Legion’s protein cookies because they’re quick protein and easy to eat on the go. I love chocolate chip cookies, so to be able to eat a cookie for part of my breakfast or as a snack in the afternoon is amazing! The texture is a little more bread or cake-like than a soft chocolate chip cookie, but remember, it’s a protein cookie. There’s only so much that can be done to make it similar to a regular cookie, so I’m happy with it!”
Whey protein is one of the most popular, widely-used forms of protein in dietary supplements. It’s recognized as a high-quality, complete protein that’s supported by multiple clinical trials. However, with various types of whey protein available, each offering unique benefits and applications, choosing the right one can be a challenge.
To identify the top whey protein products on the market, our team developed a comprehensive testing methodology and scoring algorithm to pinpoint the best of the best.
Our evaluation covers six primary categories: protein source, macronutrient calories per serving, protein per serving, price per gram of protein, sweeteners, and third-party testing. Products can also earn bonus credits that enhance their overall rating. These categories were meticulously developed in collaboration with registered dietitian and doctor of exercise physiology, Chris Mohr .
Our whey protein powder scoring methodology is an extension of our broader nutrition product and supplement methodology . Each product receives a score out of five for each category we test. These scores are then weighted by importance and averaged to produce a cumulative score out of five for each product, with one being the lowest rating and five being the highest.
You can read our full whey protein testing methodology here .
The primary source of protein in a whey protein powder formula impacts its digestibility, absorption, and the ratio of protein to other macronutrients, so this makes up the bulk of our evaluation of whey protein powders. We evaluate four different whey protein sources: whey concentrate, whey isolate, whey hydrolysate, and whey blends.
Based on research suggesting an optimal intake of 25–30 grams of protein per serving .
The majority of calories in whey protein powders should come from protein. Depending on the ingredients, calories may also come from carbohydrates and fats.
Sweeteners can enhance the taste of whey protein, but they don’t add any nutritional value. We prefer minimal sweeteners and rate them according to their nutritional profile.
Price often reflects quality, but not always. We rate whey protein powders based on their price per gram of protein
Testing certifications show whether a dietary supplement contains what the brand says it contains in the doses advertised (potency). Certifications provide a small boost to the product’s overall score and are equally weighted.
Here are the certifications that stand out:
To recognize innovation and encourage healthy competition, we incorporate bonus credits into our scores. Bonus points provide a small boost to the product’s overall score and are equally weighted.
Plant protein is an increasingly popular alternative to whey protein in dietary supplements. It’s made from plant-based sources such as peas, soy, brown rice, and seeds. While not all plant protein sources are complete proteins (containing all nine essential amino acids), most plant protein blends include at least one complete protein source.
To determine which plant protein products stand above the rest, our team developed a custom testing methodology and scoring algorithm. We evaluate plant protein powders across six categories: protein source, completeness of the protein, macronutrient calories per serving, protein per serving, price per gram of protein, and sweeteners.
These categories were developed in collaboration with registered dietitian and doctor of exercise physiology Chris Mohr , Ph.D., RD.
Our plant protein powder scoring methodology is an extension of our broader nutrition product and supplement evaluation criteria. Each product is assigned a score out of 5 for each category we test. These scores are then weighted based on importance and averaged to produce a cumulative score out of 5 for each product, with 1 being the lowest rating and 5 being the highest.
You can read our full plant-based protein testing methodology here .
The protein sources in a plant protein powder determine whether it’s a complete protein source. Some plant sources are missing or limited in one or another amino acid, making them incomplete. The source(s)n also determine the calories from protein versus carbohydrates or fats. We evaluate eight plant protein sources: soy, pea, hemp, brown rice, lentil, chia, pumpkin seed, and blends.
To be considered complete proteins, protein supplements have to consistently provide all nine essential amino acids, which are necessary for supporting muscle growth and overall development. Therefore, complete proteins receive the highest marks.
Ideally, most of the calories consumed through plant protein powder should come from protein. However, depending on the protein source and other ingredients, calories can also come from carbohydrates and fats.
Research suggests aiming for approximately 25-30 grams of protein per serving to optimize muscle protein synthesis, which can help with gaining or maintaining muscle mass as we age. While daily protein needs vary by individual, based on age, gender, training, goals and the other parts of the diet, 25-30 grams per meal meets the needs of most people. Most plant protein supplements contain around 15-30 grams of protein per serving. However, the quality, types, and combination of plant proteins may determine the ideal quantity, meaning sometimes higher amounts may be beneficial, given the source.
Price is an important factor for consumers and often (though not always) reflects the quality of a product. There are high-quality plant proteins that cost below average and relatively low-quality plant protein products that cost more than average. Because of this potential discrepancy, this category carries less weight in the overall score.
Since protein content is the best measure of value for a plant protein powder, we rate each product based on the price per gram of protein.
Sweeteners may improve the taste profile of a plant-based protein supplement, but they don’t add nutritional value beyond sometimes being a fast-burning energy source. We prefer to see minimal sweeteners in plant protein formulas, and we prefer some over others.
Nearly all reputable supplement companies conduct in-house testing for safety and label accuracy. However, many brands also opt for additional certifications to further ensure quality and safety. We award bonus credits to brands that undertake this additional step. Recognizing that smaller, newer supplement companies may not afford high-profile, third-party testing labs, we weigh certifications lower than other categories in our algorithm.
Since the supplement industry—especially protein supplements—is constantly evolving, we pay attention to products and brands going above and beyond to stand out. That’s why we incorporate bonus credits into our plant-based protein supplement scores to recognize innovation and encourage healthy competition among all brands. All bonus points are equally weighted and cumulatively provide a slight boost to the product’s overall score.
Plant protein formulas are awarded bonus credits for:
Using a protein powder from Legion Athletics is simple and versatile, making it easy to incorporate into your daily routine.
Whey protein powders, like Legion’s Whey+, are fast-digesting and ideal for post-workout recovery, but they can also be consumed at any time of day when you need a quick protein boost. ( 14 ) For example, as a sports nutrition coach, I recommend athletes consume a high-quality protein shake within 30 minutes of waking up to support muscle protein synthesis and transition from the catabolic state your body enters while fasting overnight. ( 15 , 16 ) Simply mix one to two scoops of protein powder with water, milk, or blend it into your favorite smoothie to fuel your muscles and support your fitness goals.
If you prefer a plant-based option, Legion’s Plant+ is an excellent alternative, offering high-quality protein powder derived from pea and rice proteins, with a full amino acid profile. Whether you’re vegan, lactose intolerant, or simply seeking a different protein source than whey, Plant+ provides similar flexibility and effectiveness. ( 5 ) It’s an ideal choice any time of day to meet your protein needs while aligning with your dietary preferences.
“ For those who follow plant-based diets, supplementation is even more important, as it can be difficult to reach protein goals with whole foods alone.”
Victoria Burgess, PhD, CSCS, CISSN
On the other hand, Legion Casein+ protein powder is particularly popular as a nighttime option due to its slow-digesting nature. Unlike whey or plant-based proteins, casein is absorbed more gradually by the body, providing a steady release of amino acids over several hours. ( 8 ) This makes it an excellent choice to consume before bed, as it helps to sustain muscle repair and growth throughout the night. By taking Legion Casein+ in the evening, you can ensure that your muscles receive the necessary nutrients to recover and grow while you sleep, optimizing your results.
Protein supplements from Legion Athletics are generally well-tolerated by most people. However, like any supplement, they can cause side effects depending on personal sensitivities, health conditions, or how you use the products.
The most common side effect experienced by individuals using a protein powder is digestive discomfort, such as bloating or gas, particularly when using a whey protein powder. ( 17 ) This is often the result of a lactose intolerance or sensitivity. Since Legion’s Whey+ is an isolate containing two to six grams of carbohydrates (depending on flavor), it’s very low in lactose, reducing the likelihood of such issues compared to a standard whey concentrate. If you do experience any negative side effects or have severe lactose intolerance, you may prefer a plant-based option such as Legion’s Plant+.
Another consideration is the impact of excessive protein intake on kidney health. High protein consumption can strain the kidneys, particularly in individuals with pre-existing kidney conditions. ( 17 ) Moderation is key, and we recommend consulting with a healthcare provider if you have pre-existing kidney issues or other health concerns. Additionally, while protein powders can be beneficial, remember that it is possible to meet your protein needs through a balanced diet. Research indicates that daily protein intake in the range of 1.4 to 2.0 grams per kilogram of body weight is sufficient for most exercising individuals, meaning you may not need additional supplementation. ( 18 )
The term “clean” is a marketing term and impossible to define and can vary in meaning based on your interpretation, but Legion Athletics is committed to providing products that adhere to high standards in terms of purity and quality. Legion supplements are free from artificial ingredients, fillers, and unnecessary additives, aligning with a cleaner, more natural approach to supplements.
Yes, all of the Legion’s products, including their protein supplements are third-party tested. Legion uses independent laboratories to test for heavy metals, microbes, allergens, and other contaminants, ensuring compliance with FDA guidelines. This testing also verifies that Legion’s protein supplements include the specified ingredients and quantities listed on the label, offering consumers added confidence in the reliability of Legion’s products.
