Protein Powders

proteinProteins are large organic compounds made of amino acids. Protein has all kinds of uses in the body, not just muscle building. It is used as structural material for cells and tissues, keratin of skin and elastin of connective tissue to name a few. Protein supplementation plays a big role in providing essential building blocks that help regulate the body in an incredible number of ways.

How much protein should you consume? The RDA is 0.8 grams per kg (.36 grams per lb). Depending on your goal and which diet plan you follow, this number may seem a bit low. In fact, many experts have recommended consuming as much as 1 to 2 grams per pound of body weight per day.

You can obtain the best selling protein supplements from A1Supplements.com at the lowest prices!

Find the protein supplement you are looking for in just a few clicks with iProtein.
