Best Soy Protein Powder

Soy protein has been unfairly criticized in the bodybuilding world because it was once believed to promote estrogenic effects (which can lead to a decrease in muscle mass and greater amounts of fat gain). New research has proven that this is not the case and that there are no negative effects on hormone levels by consuming soy protein.

The truth is soy protein is great for lowering cholesterol levels, it contains more glutamine than any other type of protein and it is a fully complete protein that contains all the essential amino acids!
