Whey protein is a milk-derived protein that contains amino acids, lactose, minerals and immunoglobulins, along with small amounts of fat. It is found in a variety of foods, including yogurt and cheese, and as an ingredient or powder in supplement products. There are three main types of whey protein: concentrate, isolate and hydrolysate, and they vary in how easy or difficult they are to digest.

The best whey proteins are low in carbohydrates, making them a good choice for people with diabetes or who want to lose weight. They may also help reduce heart disease risk factors, such as blood pressure and cholesterol levels.

Adding whey protein to your diet can boost glutathione levels. Glutathione is a powerful antioxidant that protects against stress, environmental toxins, and radiation. It also helps reduce inflammation, a condition linked to a wide range of health problems, including cardiovascular disease and chronic pain.

Whey protein is popular among bodybuilders, as it provides the amino acids needed to build muscle. However, it can benefit anyone who wants to add lean muscle mass or improve their workout recovery. It is also a safe option for most people, except those with pre-existing kidney or liver damage, who might experience dehydration and other problems when taking high doses of protein supplements without consulting their doctor.
