Interaction Details
There were no interactions found between Pembrolizumab and Whey Protein. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Whey Protein Overview
Whey protein is a type of protein derived from cow's milk. Specifically, whey comes from the cheesemaking process. Enzymes are added to milk, which separates the milk into cheese curds and liquid whey. Whey is a complete protein, meaning that it contains all nine essential amino acids that the body needs but cannot produce on its own. Whey protein is often used as a supplement to help build and repair muscle tissue, and it is popular among athletes and bodybuilders.
There are three main types of whey protein: concentrate, isolate, and hydrolysate. The concentrate contains a higher amount of lactose (milk sugar) and fat, while isolate is a purer form of protein that contains less lactose and fat. Hydrolysate is a predigested form of whey protein that is easier for the body to absorb.
Whey protein is often consumed in the form of powders, shakes, and bars, and it can be mixed with water, milk, or other beverages.
Drug interactions with whey protein typically result due to the calcium content of whey, which can decrease absorption of some drugs, including many classes of antibiotics.
