If you are interested in better health and improved physical fitness, you may have heard that bodybuilders and other athletes are turning to a simple, natural supplement called whey protein.

What is whey protein?

Whey protein is a pure, natural, high quality protein from cow's milk. It is a rich source of the essential amino acids that are needed by our bodies daily and are the building blocks for healthy muscles, nails, skin, and other body tissue. Whey is the by-product of making cheese and was usually thrown away as a waste product. Whey protein is an excellent choice of protein for people of all ages. Researchers now know that whey protein provides numerous benefits in areas that include sports, weight control, immune support, bone health, and general well-being. It is naturally found in mother's milk and also used in baby formula. Whey protein isolate is the purest form available. Whey protein is being considered for use as a fortifier of grain products because of its considerable health benefits and bland flavor. In addition, whey protein is easily digestible, lactose-free and is a rich source of branched chain amino acids or BCAAs. It also contains the highest known levels of BCAAs in any natural food source and these are of particular benefit to athletes and anyone who exercises hard. Although protein is also found in other foods such as meat, soy and vegetables, whey protein is proven to have the highest absorption rate (digestion) in comparison to all other foods.

Why do athletes use whey protein?

Protein levels are depleted through exercise. Muscles require the amino acid leucine. Leucine is important as it plays a key role in promoting muscle protein synthesis and muscle growth to prevent deterioration, give endurance and build mass. Proteins supply these amino acids to the muscles, which is why athletes use whey protein.

Who should consider using whey protein?

Because amino acids are 'building blocks' for the human body, it is sometimes used by patients to speed up the healing of wounds or burns.

The high quality protein that comes from whey makes it a recommended choice for those who need optimal benefits from restricted diets including diabetics, those on weight management diets and even ill patients not able to consume enough protein in their diet to assist with healing.

Can whey protein be dangerous?

Whey protein is a food and therefore does not have the risks associated with other supplements. Nevertheless, too much of anything carries risks. Extremely high use of whey protein can overload the liver, which can cause serious problems. Moderation is always recommended.

Should you be lactose intolerant you might want to try whey protein isolate, which has less than 1% lactose and is generally tolerable for most users.

Whey protein is a great natural and healthy way to bring protein into your diet and increase your general well-being.
