If you are trying to gain muscle you will need protein. Unfortunately, a lot of the protein found in our foods is also accompanied by fats and carbohydrates. In addition, proteins vary in how quickly the body can absorb the amino acids, which is known as their Biological Value (BV). Whey protein is a high BV bodybuilding supplement that has little to no fat or cholesterol. Furthermore, the whey protein isolate available from IronScience contains 80% to 90% protein, which makes them some of the most efficient and easily absorbed protein supplements on the market.
Whey comes from cow's milk. However, unlike regular dairy products, which have high levels of fat, cholesterol and lactose, whey protein contains just the protein. Because it has a rich source of amino acids, which are essential for repairing and building muscle tissue, whey protein makes the perfect bodybuilding supplement. The reason whey protein is so effective is because it contains mainly branched-chained amino acids. These are required by the body during exercise. The amino acids in whey protein repair and replace muscle tissue, aiding growth, speeding up recovery and preventing catabolism, which is when muscle tissue depletes.
