Prolab Nutrition Amino Gel-Caps supply the body with a steady flow of indispensable compounds. They are formulated without fillers or binders in a gel-cap that readily dissolves to deliver high quality nutrients. Although amino acids are obtained from whole foods, the higher nutritional demands of an athlete may require increased support. Amino acids are the building blocks of muscle and are not only essential to build, protect, and maintain lean muscle tissue, they also help to regulate hormones, create antibodies, and even DNA itself.
