Whey protein is the protein contained in whey, the watery portion of milk that separates from the curds when making cheese.
It is used for improving athletic performance, as a food supplement, as an alternative to milk for people with lactose intolerance, for replacing or supplementing milk-based infant formulas, and for reversing weight loss and increasing glutathione (GSH) in people with HIV disease.
Whey protein is also used for protein allergy, asthma, high cholesterol, obesity and weight loss, preventing allergies in infants, late-stage cancer, and colon cancer.

Whey protein is generally regarded as a safe supplement when used appropriately, but you’ll still want to take steps to make sure that you aren’t getting carried away with it. Overconsumption of protein, when coupled with a low carbohydrate intake, can lead to problems
Side effects May include:
- Gain Fats: If you’re using whey protein to build lean muscle you probably don’t want to gain weight in the form of fat. But many times whey protein will come with added sugars and therefore added carbohydrates, and some can contain added fat as well.
- Could Form Kidney Stones : Excessive amounts of protein causes kidney stones. While there is no conclusive evidence that it causes them, whey protein doesn’t seem to help prevent them, and can worsen the condition if it’s already present. One way to make sure that you don’t get kidney stones from using whey protein is to get enough fiber in your diet. Adequate amounts of fiber and water will help your body maintain itself and prevent the buildup of deposits that can lead to a kidney stone.
- Digestive Trouble: Because it is sourced from dairy, whey protein contains lactose, which could end up giving you digestive problems if you are sensitive to it.
- Could Develop Gout: It’s not likely that you’d get gout from drinking protein shakes unless you were already showing signs of it, and unless you consume far more than is recommended. But it is something to be aware of if you have a family history of gout.Along with the protein in whey protein, there is also a large amount of amino acids. If your body can’t process these effectively they’ll build up in your system and cause problems with your liver and other organs designed to filter these substances and put them to use.
