1. Best Whey Protein Powders 

Whey protein powders derive their protein from whey, the part of milk that separates from curds during the cheese-making process. It is a complete protein that the body utilizes efficiently. It has a high concentration of branched-chain amino acids (BCAAs) that helps maintain tissues and breaks down for energy during exercise, which is good for people who want to lose weight. 

Some of the top manufacturers of whey protein powders are Optimum Nutrition, Thorne Research, and NAKED Nutrition. These are the best whey protein powders they offer.

  1. Optimum Nutritional Gold Standard – Contains 24 grams of protein, 4 grams of glutamine, and 5.5 grams of BCAAs to help build and maintain muscles.
  2. Thorne Whey Protein Isolate – Contains 21 grams of protein for women and others who aren’t nearly as focused on muscle-building.
  3. Naked Whey – Contains 25 grams of protein and 6 grams of BCAAs. More BCAAs decrease muscle fatigue while building muscle.

2. Best Casein Protein Powders

Like whey protein, casein protein powders come from milk. However, the body can digest casein protein more slowly for a sustained release of amino acids into the bloodstream, sometimes for hours, which can maximize muscle growth after exercise. 

Some of the best manufacturers of casein protein powders include Ascent, CrazyBulk, and Transparent Labs. These are the best casein protein powders they offer. 

  1. Ascent Native Fuel Micellar Casein – Each scoop contains 25 grams of protein, which take 6-8 hours to digest to help prevent muscle loss post-exercise.

4. Best Pea Protein Powders 

Protein from peas has gained popularity as a vegan alternative. However, The body tends to absorb less of the protein and utilize fewer of the amino acids in plant proteins. Peas are also missing at least one essential acid, so they are not a complete protein.
