A Popular Supplement

Whey protein is not an alien term, as it resonates with people from the fitness industry and even those who are looking for an easy way to increase their daily protein intake.

What Is Whey Protein?

It is the protein from whey, the liquid left behind after milk curdles when making cheese. It comprises several proteins and contains all nine of the essential amino acids your body needs to perform vital functions. Whey is added to many food products including ice creams, and chocolate bars.

The Types of Whey

Health.com classifies whey into three categories - whey protein concentrate, whey protein isolate, and whey protein hydrolysate.

Benefits

The main benefits of whey protein include increased muscle mass, a reduction in appetite that promotes weight loss, and a possible reduction in heart disease risk factors. Despite these benefits, there has been an ongoing debate over the safety of whey protein, specifically, its components. So what are the side effects?

Side effects

Some whey protein powders might be high in added sugar and calories, and the risk here is weight gain and an unprecedented spike in blood sugar. People with dairy allergies have gastrointestinal discomfort if they use a milk-based protein powder, says registered dietitian Kathy McManus. Whey can also contribute to acne development.
