Whey protein comes in three forms: isolate, concentrate, and hydrolyzate. Hydrolyzed whey protein is popular among bodybuilders due to its high-quality protein and easy absorption. It can also be used to reduce muscle wasting in HIV patients and has other potential health benefits. However, caution is advised for those with milk allergies or taking certain medications.
Whey protein is a byproduct of cheese production. It is available in three forms: isolate, concentrate, and hydrolyzate, and each has somewhat different properties. Whey protein hydrolyzate, also known as hydrolyzed whey protein, is a popular nutritional supplement, particularly among bodybuilders.
As with all three forms, whey protein hydrolyzate contains high-quality protein and therefore includes all eight essential amino acids required by adult humans. Whey protein hydrolyzate is more processed than other forms, pre-digested, and provides the highest quality protein. Due to its predigested state, hydrolyzed whey protein is more easily absorbed than isolate or concentrated versions. Additional processing can increase the cost of the hydrolyzate form compared to the cost of isolating or concentrating. In addition to being an excellent source of protein, whey protein can help strengthen the immune system.
Whey protein is used as a bodybuilding supplement because it provides a large amount of branched-chain amino acids (BCAAs). BCAAs, particularly leucine, trigger protein synthesis and provide energy to muscles as they are exercised. When taken during exercise, whey protein increases blood flow and therefore nutrients to the muscles. After exercise, the use of whey protein can help increase muscle mass.
Some medical professionals have also found the whey protein supplement to be effective when used by HIV patients in reducing muscle wasting. Although more evidence is needed to verify effectiveness, other uses include reducing the incidence of allergies in infants, nutritionally supporting those with lactose intolerance, and treating patients with obesity, high cholesterol, asthma, and late-stage cancer.
Whey protein hydrolyzate can be found in forms that make supplementation simple and convenient. It is available as a protein powder to make shakes or added to other foods. Whey protein nutritional supplement is also used as an ingredient in some commercially manufactured protein bars.
Although the hydrolyzate version may be less allergenic than the isolated or concentrated forms, caution is still advised for people who are allergic to milk and considering taking this protein supplement. Although hydrolyzed whey protein is generally safe for healthy, non-allergic adults, high doses can cause headache, nausea, cramps, fatigue, or other side effects. Some medications can interact with whey protein, and patients should consult a healthcare professional before supplementing with hydrolyzed whey protein. Women should avoid the use of whey protein hydrolyzate if they are pregnant or nursing.
