Most bodybuilders would agree that supplementing with whey protein is an important element in achieving serious muscle gains. This article will examine the facts relating to whey protein as a supplement and help you decide whether you need to follow this particular strategy. Whey protein is produced during the process that sees milk turned into cheese. It is also found naturally in dairy products, eggs, soy and vegetable proteins but none of these compares in quality to whey protein powder. It also scores highly in providing the branched chain amino acids (BCAA's) that are important in the building and retention of muscle. Whey protein is highly favored by bodybuilders because it provides the necessary building blocks to produce the amino acids that the body uses to build lean muscle tissue. Many studies have shown that whey protein contains the perfect combination of amino acids, in just the right concentration for optimal performance in the body. It is also thought that whey protein has a role as an anti-oxidant and immune system builder. It is best taken in powder form mixed in juice or milk, spread throughout the day to maintain a positive nitrogen balance. Serious bodybuilders often consume up to 150 grams each day but as a rule of thumb, daily protein intake for active trainers can be calculated by taking your weight in pounds and multiplying by 1 or 1.5. But remember, you need to work out how much protein is taken from food and other sources, and then spread the remaining whey protein balance over the day. Whey protein is a relatively safe supplement but no more than 30 grams of protein should be taken at one sitting as excessive single doses could overload the liver. The safety of whey protein has been well documented in many scientific studies and there is clear proof that taken consistently, coupled with regular exercise, it will result in meaningful muscle gain.
