Protein itself is responsible for hundreds of functions in the body. It helps with muscle preservation, weight maintenance, cell regeneration, hair growth, immunity and healthy skin just to name a few things.

According to RDA guidelines, the recommended amount of protein a day is .8 grams per kilogram of body weight. Another thing to take into consideration is overdosing on whey protein. The body can only process and digest so much at a time. If an overabundance is taken, it will be excreted from the body, stored as fat or ultimately used for energy. But processing these high amounts of protein can really tax the liver and kidneys which can lead to problems down the road.

High amounts shouldn’t be taken by people with pre-existing kidney problems. In either case, proper hydration is of utmost importance when supplementing with whey protein as it takes the body a lot of water to metabolize. An easy rule of thumb is drink eight, 8 oz. glasses of water a day.
