What are the side effects of whey protein powder?

Whey protein powder is generally considered safe when consumed in moderate amounts, but like all dietary supplements, it can cause side effects in some people. Some of the most common side effects of whey protein powder include:

  • Digestive issues: Bloating, gas, and diarrhea can occur in some people who consume whey protein powder, especially if they have a lactose intolerance.
  • Allergic reactions: Some people are allergic to the proteins found in whey, and may experience symptoms like hives, itching, and shortness of breath.
  • Kidney problems: Consuming large amounts of protein, including whey, can put a strain on the kidneys, particularly in people with pre-existing kidney conditions.

It's important to note that these side effects are not common and typically only occur in people who consume excessive amounts of whey protein powder or who have pre-existing health conditions. To minimize the risk of side effects, it's recommended to follow recommended daily protein intake guidelines and to consult with a healthcare professional or registered dietitian before starting to use whey protein powder.
