Soy protein concentrate is produced by filtering liquified soy, a process which is used to isolate soy protein while allowing some carbohydrates and fiber remain. This concentrate is used as the primary protein in many vegetarian and vegan muscle-building protein powders.
Soy protein is a complete protein in that it contains all of the essential amino acids required in one’s diet. Soy protein concentrate supplements can be used as a gluten-free, vegan source of protein. See: Soy
