Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Whey protein is scientifically studied as a supportive nutritional intervention for cancer patients, particularly to help reduce the side effects of cancer treatments such as chemotherapy and radiation. Cancer therapies often lead to muscle wasting, malnutrition, weight loss, and compromised immune function. Whey protein, being a high-quality, easily digestible protein source rich in essential amino acids (notably leucine), has shown potential in addressing these issues. Several clinical studies and reviews have indicated that whey protein supplementation can help maintain or improve muscle mass, support immune function, and enhance overall nutritional status in cancer patients.

Some evidence suggests that whey protein may also help improve patients’ quality of life by reducing treatment-related fatigue and supporting faster recovery from tissue damage. Additionally, the high cysteine content in whey protein can boost glutathione production, an important antioxidant that may help combat oxidative stress related to cancer and its treatment.

However, while there is moderate scientific support (hence a rating of 3), it is important to note that whey protein is considered an adjunct—meaning it is supportive, not curative, and should be used under medical supervision, particularly because individual nutritional needs can vary greatly among cancer patients. More high-quality, large-scale randomized controlled trials are needed to further clarify the extent of benefit and best practices for supplementation.
