- Protein powder is a dietary supplement that promotes increased muscle mass when used with exercise. It can be made from whey, eggs, soy or rice. The source materials are processed for their protein content and turned into powder. Whey protein is the most commonly used although there are a number of alternatives. Egg white protein contains no dairy or lactose, and soy protein is a viable alternative for vegetarians who wish to take a protein supplement.
- The protein powder is used with milk or fruit juice to make a protein shake. Protein can also be sprinkled on cereal. Eating the protein powder begins the chemical reactions during digestion, so that the protein can be put to use. Most people who take protein powders do so immediately before an exercise regimen, so as the protein breaks down, it is immediately put to work reinforcing and building muscle tissue.
- Protein is broken down during digestion by dietary enzymes called proteases. Once broken down, the proteins are converted to amino acids. High levels of amino acids in the body (the building blocks of protein) promote the efficient growth and repair of muscle tissue. It can also improve immune health. However, not everyone responds to protein powders the same, and you should check with a nutritionist before starting a diet using protein powder.
