best protein powder for men 2020

Whey can be digested by your liver quickly, and it contains all the essential amino acids that your body can’t produce on its own. If you’re looking to lose weight and build muscles at the same time, whey can help with that by suppressing your appetite [1]. 

If you’re someone who works out regularly or participate in high-intensity training, whey protein can also help your muscles recover faster and decrease muscle loss [2]. 

Many brands produce whey protein, but it’s rare to find one developed by a team of scientists and doctors like Dymatize. It has over 3000 reviews on Amazon, of which the majority are positive feedback.

A lot of long-time users have appreciated the quality of the protein powder and its taste. You’ll also notice positive comments about its ability to boost muscle growth and performance.

  • Doctor developed protein powder
  • Available in multiple flavors
  • More lactose-intolerance friendly than whey concentrate
  • Quality tested and certified

Best Protein Powder for Before Bed

Optimum Nutrition Casein

casein for men

Casein protein is often ignored because it’s not as effective as whey when it comes to muscle building. However, combining both casein and whey can be an excellent strategy to grow and protect your muscles. 

Casein is a slow-digesting protein, which means if you take it before bed, it will digest slowly and help with the overnight muscle protein synthesis and recovery [3]. 

Optimum Nutrition is one of the top-rated brands in the protein powder category, and they’re also one of the largest sports nutrition companies. Their gold standard casein powder is produced with Micellar Casein, which is one of the best. 

The raw ingredients used in their protein powders go through rigorous quality checking process to the point they can even reject huge loads that if they fail to meet their criteria. 

A lot of muscle-building men have commented that combining casein with whey helps them feel and perform better. 

  • One of the best and largest sports nutrition companies
  • High-quality premium ingredients
  • Great for night time muscle recovery and synthesis
  • Available in multiple flavors
  • Not the best choice as a pre or after workout protein
  • Not the best choice for muscle building if used alone

Best Protein Powder For Men FAQ

Answers to some common questions you may have about protein powders for men. 

What is the Best Protein Powder for Athletes?

If you don’t have milk allergies, and if you’re not a vegan, whey protein powder is the first best choice for athletes. The main reason is that it has more research to back it up compared to other types of protein.

Whey is considered a complete protein because it contains the growth and development nutrients of bovine milk. It provides your body with all the essential amino acids that it can’t produce on its own.

It’s also a fast-digesting protein, which is one of the reasons why it’s considered the best pre and post-workout protein powder. 

Whey isolate, such as the one we’ve discussed in this article, is one of the purest forms of whey protein because it has more protein and less of other nutrients (fat and lactose). As a result, it’s more suitable for those who have a sensitive stomach [8].

A recent meta-analysis study investigated the effect of whey protein on performance in athletes. They found that the whey protein supplement was safe and significantly enhanced performance, muscle strength, and recovery in athletes [9]. 

You might also want to take casein before bed because it’s a slow-digesting protein that helps with muscle synthesis and recovery during the night. 

What is the Best Protein Powder for Men’s Weight Gain?

Whey concentrate and whey isolate are the first best for men’s weight gain, and the second-best would be beef protein isolate. Both whey and beef protein isolate are complete protein sources and have the best effect when it comes to muscle growth and strength. 

An 8-week resistance training study compared the effect of beef, chicken, and whey proteins in forty-one men and women. The participants were divided into four groups, one for each protein source and one control. 

They were given 46 grams of protein powder supplement after a workout and at the same time on non-workout days. Results showed that those who consumed whey protein had the highest increase in muscle mass, followed by beef protein, and then chicken.

There was not a big difference between the three groups of protein, and all three also had a greater fat loss and better body composition [10].

So our first recommendation would be whey and beef protein isolate for weight gain. However, if you can’t have them for some reason, soy and pea proteins are good alternatives. 

What is the Best Protein Powder for Weight Loss?

All five of the protein powders discussed in this article can be used for weight loss. The primary reason is that protein powder on its own is not going to help you lose weight. You’d still have to follow a healthy diet and cut down some calories to speed up weight loss. 

E.g., a 12-week study conducted in obese participants found that those who took the whey protein supplement lost significantly more fat and less lean body mass compared to the control group [11]. 

Soy protein is an excellent alternative if you have a dairy allergy, or you’re a vegan. One study conducted on seventy-one overweight and obese participants found that soy protein enhanced weight loss and body composition [12]. 


  1. Whey protein isolate and animal protein such as beef protein isolate are the first best for men who wish to build muscles, improve strength, body composition, and performance. 
  2. If you’re allergic to milk, soy, and pea protein powders are great alternatives. 
  3. Taking casein protein powder right before heading off to sleep can help with nighttime muscle growth and recovery.
