The 9 Best Protein Powders for Athletes [2024 Guide]

Rachel Levin


In the world of athletic performance and enhancement, creatine has carved a well-deserved spot in the line-up. It stands out for its ability to boost strength, enhance recovery, and promote muscle growth. And it has a lot of science to back it up.

According to Andy Galpin, Ph.D., scientist, coach, teacher, and Momentous partner, “creatine is one of the most established and well-rounded supplements ever developed. It’s actually absurd how effective creatine is, especially with even more evidence coming out now in regards to cognitive function and neurological disease.”

The key to unlocking these benefits without compromise lies in choosing creatine that is certified clean. Products verified to be free from contaminants and deemed safe for athletes are among the most important criteria that should be respected in the pursuit of choosing the right creatine—and really any other supplement.

Recognizing the importance of purity and safety, third-party certifications like NSF’s Certified for Sport and Informed Sport are invaluable markers of trust. They do the heavy lifting to make the research process easier for you. These certifications ensure that the supplements meet rigorous testing criteria, providing athletes with the peace of mind they need to focus on their performance.

We put together a 2024 guide to creatine for athletes designed to help you navigate the myriad of options available, helping you find the best creatine supplements tailored to your athletic goals. Whether you’re aiming to increase your strength and power, speed up your recovery, or gain lean muscle, we’ve got you covered.

We’ll start the list with our own creatine supplement at Momentous, which is fully NSF and Informed Sport certified. 

While there are endless protein supplement brands out there, there are only a handful that focus on creating a product engineered with athletes in mind.

With a keen eye on products boasting a clean bill of health and awarded third-party certifications like NSF Certified for Sport and Informed Sport, we aim to introduce you to a world where your protein powder is as committed to your performance and safety as you are. From ingredient purity to the source of the protein to the price per serving—this guide has you covered.

We’ll give an overview of everything we look for in a protein powder and tell you everything you need to know to make the right decision. Beyond a list of the best protein powders currently available to athletes, we’ll also recommend the following:

  • What to consider when choosing a protein powder

  • The benefits of incorporating a protein powder into your daily diet

  • And some general FAQs we’ve heard from customers related to protein powder

We’ll start the list off with our own protein powders at Momentous—both the Grass-Fed Whey Protein Isolate and Essential Plant-Based Protein. But keep your options open; we'll explore a variety of standout choices that cater to diverse needs and preferences.

After testing dozens of protein powders in my quest for the perfect post-workout shake, Momentous has emerged as my go-to. Their Grass Fed Whey Protein Isolate in chocolate flavor tastes incredible and has become a highlight of my workout routine. Unlike my past experiences where protein powders were merely a necessity, I genuinely look forward to mixing this chocolate delight with a banana, a scoop of peanut butter, and water after an intense session.

Momentous products are engineered through the collective expertise of registered dietitians and performance experts from leading professional sports teams.

Their goal? To create a product that satisfies the nutritional needs of elite athletes and exceeds them. The choice of whey protein isolate from European dairy farms underscores a commitment to quality and environmental sustainability, with milk sourced from grass-fed cows.

What seals the deal for me is the addition of ProHydrolase. This enzyme ensures that the protein is absorbed more effectively and is gentle on the stomach, a stark contrast to the digestive discomfort I've experienced with other brands. Warm it up with milk or water, and you're in for a cozy, hot cocoa-like treat that's both comforting and nourishing.

While the Grass Fed Whey Protein is my top pick, the Essential Plant-Based Protein in vanilla chai is a close runner-up. Its smooth consistency and easy mixability, whether in water or milk with a banana and some nut butter, make it reminiscent of ice cream - but with the added benefits of a complete amino acid profile thanks to its pea and rice protein blend. This isn't just about muscle building or repair; it's about holistic health, from enzyme production to hormonal balance and immune support, without the dreaded chalky taste common in plant-based options.

It’s worth noting that excellence comes at a price, and Momentous sits at the premium end of the spectrum. For those prioritizing cost, alternatives like Optimum Nutrition might offer a more budget-friendly option. Yet, for me, the quality and experience Momentous delivers are unmatched, making it a staple in my supplementation toolkit.

It's recognized for providing the essential fuel to support muscle gains with a formula that keeps nutritional balance in mind. Taste-wise, it's considered favorable, making it a pleasant addition to any post-workout routine. However, some customers have pointed out an off-putting odor that might detract from the overall experience. It comes in over ten flavors, so you’re guaranteed to find the right one for you.

Optimum Nutrition’s plant-based option is a hit among customers for its natural muscle development capabilities. It offers a balanced nutritional profile that manages carbohydrates and fats efficiently, appealing to those seeking to build muscle on a lactose-free or vegan diet. However, similar to its Whey counterpart, the Vegan blend receives some criticism for its distinct smell.

What Are The Benefits of Protein Powder for Athletes?

Understanding the science-backed benefits of protein supplementation can help you leverage this powerful nutritional ally to your advantage. Here are the top benefits, each supported by research and relevant to various training scenarios:

1. Enhances muscle growth

For athletes looking to build muscle, protein powder is a cornerstone. It provides the essential amino acids needed for muscle protein synthesis, the process responsible for muscle growth and repair.

A study published in the Journal of the International Society of Sports Nutrition highlights the role of protein supplementation in increasing muscle mass and strength in individuals engaged in resistance training regimes.

Specific scenario: After a rigorous session of weightlifting, consuming a protein shake can significantly aid in muscle repair and growth, making your efforts even more worth your while.

2. Accelerates recovery times

Recovery is critical to an athlete's training regimen. Protein powder can speed up recovery from muscle soreness and injury, allowing athletes to return to training sooner.

According to research in the American Journal of Clinical Nutrition, protein supplementation helps reduce muscle damage and improve muscle performance and protein synthesis after exhaustive exercise.

Specific scenario: For runners, consuming a protein shake after a long-distance run can help reduce leg muscle soreness and accelerate recovery, ensuring they're ready for their next session without delay.

3. Increases strength and power

Athletes seeking to improve their strength and power can benefit significantly from protein powder.

A systematic review in the British Journal of Sports Medicine found that protein supplementation could enhance strength and power outcomes in resistance-trained individuals, particularly when consumed post-exercise.

Specific scenario: For cyclists or sprinters, integrating protein powder into their post-workout recovery routine can contribute to noticeable gains in leg power and endurance over time.

4. Convenient source of protein on the go

With demanding schedules, athletes often struggle to consume sufficient protein through whole foods alone. Protein powders offer a convenient, portable solution, ensuring athletes meet their daily protein requirements. This convenience supports continuous muscle repair, growth, and overall body function, which is critical for athletes constantly on the move.

Specific scenario: For busy athletes, a protein shake can be a lifesaver on hectic days, providing a quick and easy way to fuel the body between training sessions or competitions without the need for meal prep or cooking.

5. Supports immune system function

Intense training can sometimes suppress the immune system, making athletes more susceptible to illness.

Protein, particularly from high-quality sources like whey, plays a crucial role in supporting the immune system. It aids in the production of antibodies and supports gut health, a major hub for immune activity. Research findings indicate that whey protein, in particular, has immune-supporting properties, including enhancing antioxidant production.

Specific scenario: During periods of rigorous training, increasing the intake of protein can help strengthen the body's defenses, keeping athletes healthy and competitive with minimal interruptions from sickness.

6 Things Athletes Should Consider When Choosing Protein Powder

Beyond just picking any protein off the shelf, consider these crucial factors to find your perfect match:

1. Protein source

Different protein sources cater to different needs.

Whey and casein are popular for their fast and slow-digesting properties, respectively, making them great for post-workout and overall recovery. Plant-based options, like pea and rice protein, offer a complete amino acid profile essential for muscle repair and growth.

Momentous specifically blends pea and rice proteins for the plant-based blend to achieve this balance, ensuring their formula is not only effective but also mindful of dietary preferences and concerns about sugar and heavy metal content.

2. Third-party certification

For athletes, the purity of a supplement is non-negotiable. Third-party certifications such as NSF Certified for Sport and Informed Sport guarantee that a product is free from banned substances and contaminants.

This assurance allows athletes to use their chosen protein powder with confidence, knowing they are not at risk of failing doping tests and that the product meets stringent safety standards.

3. Free from artificial ingredients

The presence of artificial ingredients can be a concern for health-conscious athletes. Choosing protein powders free from artificial sweeteners, colors, and flavors ensures that you're fueling your body with high-quality, natural ingredients.

This approach aligns with a holistic view of nutrition, focusing on clean, minimal processing. Choosing an optionthat has third-party certifications can certainly help with this aspect, but taking a deep dive in the ingredient list is crucial.

Take a good look at the type of sweeteners used — that can be a real make or break depending if you’re partial to stevia, monk fruit extract, cane sugar, or another sweetener.

4. Absorption and digestion

Efficient absorption and easy digestion are key to the maximum benefit of your protein powder. Ingredients like ProHydrolase in the Momentous whey protein enhance the breakdown and assimilation of protein, making it more accessible for muscle repair and growth.

This not only improves athletic performance but also minimizes digestive discomfort often associated with protein supplementation.

5. Mixability and taste

The practical aspects of protein powder, such as how well it mixes with liquids and its taste, significantly impact its usability.

A protein that blends smoothly with water or milk without clumping and comes in a variety of palatable flavors encourages consistent use, which is essential for reaping the long-term benefits of protein supplementation. Consider how you like to consume your protein, whether it’s a smoothie, a shake, oatmeal, or a baked good like pancakes or muffins.

6. Price

Finally, consider the price and overall value. High-quality protein powders may come with a higher price tag, but the cost per serving can provide a more accurate measure of value. Look for options that balance quality and cost fairly, including potential savings through subscriptions or bulk purchases.

To help you tackle this aspect, refer back to our chart breaking down the price per serving and price per gram of protein of each powder listed above.

Are There Any Side Effects of Protein Powder Supplementation?

Digestive issues are among the most common concerns, with some individuals experiencing gas, bloating, or diarrhea. This discomfort is often due to the body's reaction to certain ingredients or the sheer amount of protein being introduced.

Some protein powders include digestive enzymes like ProHydrolase, which enhance the breakdown and absorption of protein, thereby easing the digestive process. Choosing a protein powder that supports digestive health can make your protein supplementation both effective and comfortable.

Kidney issues represent another area of concern, particularly when protein intake exceeds the body's needs over a long period. High protein consumption can put additional strain on the kidneys, which are responsible for filtering waste products from the blood.

It's essential for individuals, especially those with preexisting kidney conditions, to consult with healthcare professionals before significantly increasing protein intake. Moderation and medical guidance are key in leveraging the benefits of protein powders while safeguarding against potential renal stress.

What The Experts Say: Real Athlete Experiences with Protein Supplementation

Juliet Starrett, life-long athlete and co-founder of San Francisco CrossFit: “Every time I work out, regardless of whether it's a long mountain bike ride, or a short CrossFit workout, or a stand-up paddle, or whatever, within 30 minutes of finishing, I have a scoop of protein. It’s a simple habit that makes a huge difference for me.”

Brandon McDaniel, LA Dodgers VP of Player Performance: "For those of you who can have dairy and prefer it, Momentous Grass-Fed Whey Protein is for you. Whey protein has been around for a long time, but with Momentous it's the highest quality of protein that you can get. It is formulated to expedite recovery—it's like a freight train running to your muscles.

"I needed to make sure that protein was getting to my athlete's muscles so they could recover after their workout, after their game, and come back the next day and perform at a high level. The plant based protein has pea protein and rice protein to help with that full amino acid profile. It has a lot of nutrients in there that are going to help rush the protein to the cells."

Dr. Andy Galpin, PhD, Professor of Kinesiology: "Momentous is also driven by science and not cheap marketing or quick thrills. They aren’t scamming you by turning high-profit stimulants, low-quality protein powders, or questionable ‘ingredient stacks’. Rather, they focus on science-based single ingredients so you can include, remove, or adjust your protocols based on your unique physiology and changing circumstances. I get asked daily for supplement recommendations, and for the first time in my 20-year career, I finally have an answer!” 

Protein Powder FAQs for Athletes

Is a specific type of protein best for cardio?

For cardio-focused athletes, a protein that's easily digestible and quick to absorb, such as whey protein, is often recommended. It supports muscle recovery after prolonged endurance activities without weighing you down before your workouts.

Is it better to supplement with protein before or after a workout?

Supplementing with protein after a workout is generally considered more beneficial for muscle recovery and growth, as it helps repair muscle tissue damaged during exercise. However, consuming protein before a workout can also support sustained energy and performance, especially in longer training sessions.

Should I supplement with protein on rest days?

Yes, supplementing with protein on rest days is important for continuous muscle repair and growth. Your muscles grow and recover on rest days, and protein supports this process, ensuring you're ready for your next workout.

Can I have a protein shake on an empty stomach?

Yes, you can have a protein shake on an empty stomach, especially if you prefer working out in the morning or if it's been a while since your last meal. Many find it a convenient and quick-digesting option to fuel their bodies and support their workouts.

Is creatine or protein powder better for athletes?

Creatine and protein powder serve different purposes, making them both valuable for athletes. Creatine is primarily used to improve strength and increase muscle mass, while protein powder supports muscle repair and growth. Depending on your fitness goals, you might benefit from incorporating both into your nutrition plan.
