Whey protein is a mixture of some of the proteins naturally found in milk. The major proteins found in whey protein include beta-lactoglobulin and alpha-lactalbumin. Whey protein has one of the highest protein digestibility-corrected amino acid scores (PDCAAS; a measure of protein bioavailability) and is more rapidly digested than other proteins, such as casein (another milk protein). 1

How to Use It

Some benefits of whey protein have been demonstrated with as little as 20 grams per day. For athletes in training a commonly used amount is 25 grams of whey protein per day, and shouldn’t exceed 1.2 grams per 2.2 pounds body weight. Most clinical research has used similar amounts of whey protein.

Where to Find It

During the process of making milk into cheese, whey protein is separated from the milk. This whey protein is then incorporated into ice cream, bread, canned soup, infant formulas, and other food products. Supplements containing whey protein are also available.

Possible Deficiencies

People who do not include dairy foods in their diets do not consume whey protein. However, the amino acids in whey protein are available from other sources, and a deficiency of these amino acids is unlikely.

Interactions with Supplements, Foods, & Other Compounds

At the time of writing, there were no well-known supplement or food interactions with this supplement.

Interactions with Medicines

As of the last update, no reported interactions between this supplement and medicines. It is possible that unknown interactions exist. If you take medication, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.

Side Effects

People who are allergic to dairy products could react to whey protein and should, therefore, avoid it.2 As with protein in general, long-term, excessive intake may be associated with deteriorating kidney function and possibly osteoporosis. However, neither kidney nor bone problems have been directly associated with consumption of whey protein, and the other dietary sources of protein typically contribute more protein to the diet than does whey protein. The possibility that certain proteins in milk may contribute to the development of diabetes in children is controversial. But since whey proteins include some of the same milk proteins, people who are avoiding milk because of concerns about the risk of diabetes should not consume whey protein either.
