Wow - good for you. My source was a sports psychologist that teaches at the University where I live. One time I was on this years ago and he told me. To confirm, I took a Science of Nutrition. You could ask almost anyone who is into physical fitness and they will confirm this. The body takes what it needs from you. I am glad you are doing so well. I didn't mean to trip people out, but rather give a heads up. The spirulina is sea weed that is loaded with protein. With this capsule, you can alleviate the need for your body to take what it needs to carry on. Hope this helps. peace out, Marcie
