What Should Athletes Look For In A Protein Powder?
There are a number of third-party organizations that regularly test supplements to ensure that they don’t contain any banned ingredients and that ingredient label claims are met.
All of the products in this article are certified by at least one of the following:
- Informed Sport
- Informed Choice
- NSF Certified for Sport
Informed Sport Certification

When it comes to choosing the best supplements, athletes should mainly look at products with an Informed Sport Certification.
Informed Sport basically requires more frequent testing than the Informed Choice Certification, as a way of ensuring that every batch of the product is of the highest standard. This involves rigorous testing which provides an extra layer of assurance, verifying that the protein powder is safe, high-quality, and free of any substances that could potentially harm an athlete’s performance or health.
NSF Certified Sport

Another certification to look out for is the NSF Certified Sport. This certification acts as confirmation that the product doesn’t contain any banned substances, ensuring athletes’ safety and eligibility. Also, it verifies that the product’s content is legitimate and free from unsafe levels of contaminants.
Lastly, the NSF Certified Sport certification guarantees that the product is manufactured in line with Good Manufacturing Practices (GMP) and in a certified facility. This pretty much means that the protein powder has been produced under strict quality control standards, which further ensures that it’s safe for consumption.
Informed Choice Certification

And the last indicator to look out for is the Informed Choice Certification. It’s another reliable way of verifying the quality of a protein powder. It follows the same strict guidelines as Informed Sport, ensuring that the product is free from banned substances and meets high-quality standards.
But, unlike Informed Sport, Informed Choice doesn’t test every batch of the product. This may seem like a bit of a drawback, but it’s still a reliable certification that guarantees that the product will be safe and actually work. Athletes can comfortably use products with the Informed Choice certification.
What Are The Benefits Of Protein Powder For Athletes?
Muscle Repair and Growth
Protein powders play a key role in helping muscle repair and growth, especially for athletes. Training and physical activity cause muscle proteins to break down. Consuming ample protein helps repair the damaged fibers while promoting the growth of new ones, this process is known as protein synthesis.
This is where protein powders come in handy. They’re a concentrated source of high-quality protein that can support muscle repair and growth, so athletes can build stronger, more resilient muscles. Protein powders are especially beneficial after hard workouts when the body needs protein to kickstart the recovery process.
Recovery
Most pro athletes will constantly stress the importance of recovery in any training regimen. Protein powders can make the recovery process much smoother. Having enough protein after a workout can reduce muscle soreness, improve strength, and speed up recovery. This is because protein gives you the essential amino acids needed to repair and rebuild the muscle tissues damaged during exercise.
If you add a protein shake to your post-workout routine, you’ll be giving your body the nutrients it needs to recover effectively. This can lead to improved performance in your next workouts and a lower risk of injury.
Performance
Whatever your discipline, having a regular protein intake is important for supporting athletic performance. Protein helps with improving muscle strength and body composition, both of which are important for athletes. Consuming enough protein can help maintain muscle mass during periods of intense training or when your calorie intake is restricted.
It can also support muscle growth when you’re doing strength training. This is why many athletes go for protein powders that are made from whey protein, as they provide a quick source of amino acids that can stimulate muscle protein synthesis and promote performance.
Convenience
In the fast-paced life of an athlete, convenience is key. Protein powders give a quick and easy way to increase your protein intake, especially when you don’t have immediate access to whole-food protein sources or when they’re not practical.
Whether you’re rushing off to work after a morning workout or need a quick recovery shake after training, protein powders can be easily mixed with water or milk for a high-protein drink that tastes nice and gets the job done. They’re also portable, easy to prepare, and can be consumed pretty much anywhere, making them a convenient solution for athletes trying to meet their protein needs.
Meeting Increased Protein Needs
Athletes typically need more protein than inactive people to support their higher levels of physical activity.
Protein powders can help athletes meet these increased needs in a convenient and measurable way. They’re a concentrated source of protein that can be easily added to an athlete’s diet in many different ways. This ensures they get the necessary amount to support their training and recovery.
Whether it’s whey protein, casein protein, or plant-based protein powders, athletes can choose the one that best fits their dietary preferences and nutritional needs.
Weight Management
Protein is known for giving people feelings of fullness, which can help manage appetite and support weight management or weight loss. This is particularly important for many athletes in sports with weight categories or sports that emphasize having a certain body composition.
By incorporating protein powders into your diet, you can control your calorie intake while ensuring you get enough protein to maintain muscle mass and support recovery. They can be a valuable tool in achieving the desired body without compromising performance or health.
Protein Consumption Tips For Athletes
Timing
There’s a common belief that protein has to be consumed within an hour before or after working out, but don’t stress too much about this. Studies have found no significant impact on strength or hypertrophy between groups that consumed protein within this timeframe and those that didn’t.
Ignore everything, just focus on consuming enough protein throughout the day. This will effectively support muscle repair, growth, and overall athletic performance.
Use a macro tracker
Using a macro tracker can be a game-changer for athletes. It allows you to track your calorie intake and weight, helping you dial in your Total Daily Energy Expenditure (TDEE).
By having a clear idea of your energy intake and expenditure, you can make better decisions about your diet and ensure you’re meeting your protein needs.
Calculate your TDEE
If you want to manage your diet effectively, then knowing your TDEE is an important step. Once you’ve calculated your TDEE, aim to eat above it by about 300 and 500 calories per day, if you’re looking to gain weight at a steady rate. This will give your body the extra energy it needs to build muscle and recover from workouts, without resulting in excessive fat gain.
Aim for about 0.7 grams of protein per pound of lean body mass
When it comes to getting in enough protein, a good rule of thumb is to aim for about 0.7 grams of protein per pound of lean body mass. This means your body weight minus fat.
For example, a person who weighs 100 pounds and has 15% body fat has 85 pounds of lean body mass. This approach ensures you’re getting enough protein to support muscle growth and recovery, without overdoing it.
Extra bulking tip
If you’re looking to bulk up, there are some simple ways to add extra calories to your protein shake. Try adding ingredients like coconut oil, raw honey, or nut butter (peanut or almond butter).
Besides boosting the caloric content of your shake they can also enhance its flavor. But, if you’re mainly focused on building lean muscle without weight gain, just skip these additions.
Be sure to check our review of the best bulking supplements on the market.
Use whole milk
Here’s another simple yet effective bulking tip: consider mixing your protein powder with 16 oz of whole milk. This simple switch can add an extra 300 calories and 16 grams of protein per serving to your shake, supporting your weight gain goals while giving your shake a nice, creamy texture.
Use skim milk
Increasing your protein intake without adding a ton of extra calories isn’t rocket science. We’d recommend skim milk, as it’s a great choice for a protein powder mixer. It provides additional protein and nutrients without the extra fat and calories found in whole milk, making it a perfect option for those aiming for lean muscle gain or weight management.
FAQs
Yes, protein powder is completely safe for most teenage athletes. It’s an easy way to ensure they’re getting enough protein to support their growth, development, and athletic performance. But, it’s important to remember that protein powders should supplement a balanced diet and not replace whole foods. Always consult with a healthcare professional or a dietitian before starting any new supplement regimen.
Check out our review of the best protein powders for teens for a look at some well-trusted supplements.
Although protein powders rarely contain substances banned in sports, it’s vital for athletes to be cautious about which protein powder they choose. Some pre-workout supplements, for example, may contain stimulants prohibited in athletic competitions, particularly if they have a “proprietary blend” of sorts.
To avoid any risks of accidentally consuming banned substances, we’d recommend athletes go for protein powders that are certified by Informed Sport, Informed Choice, or NSF Certified Sport. These certifications ensure the products have been tested and are free of banned substances.
Protein powder offers athletes several benefits. They aid muscle repair and growth, which is very important after long workouts. They also support overall recovery by replenishing the body’s protein stores, so athletes can bounce back faster. Lastly, they can improve performance by providing you with the essential amino acids which play a big role in muscle protein synthesis.
Conclusion
Look, all the protein powders we’ve mentioned have their benefits, but we can’t deny that 100% Grass Fed Whey Protein Isolate by Transparent Labs is a top choice. It gives you everything you need and more in terms of a protein blend while serving as a clean and trusted product.
