Whey Protein Side Effects:

There are a few, but very limited, side effects to using whey protein powders. The most important is that whey protein is derived from dairy, so if you are lactose intolerant, you may want to stay away. Whey protein isolate often filters out the lactose, so you can try a pure whey protein isolate, but we can't guarantee any results.


As mentioned in the protein side effects page, one common misconception is that excessive protein intake is harmful for the kidneys. However, this protein safety study on male bodybuilders showed that kidney function and excrement were within normal ranges. Nitrogen levels began to rise, however, so it is recommended to drink plenty of water with a high-protein diet. On the other hand, high-protein diets in women have been shown to increase calcium excrement. Calcium supplements are very important for women to take, as shown by this high-protein, high-calcium diet study, in which bone tissue loss was minimized.

Is Whey Protein safe?

Yes, whey protein is safe for bodybuilders and competitive athletes who are not lactose-intolerant. As mentioned above, women should use extra calcium with high-protein diets, and all protein users should drink enough water. It's important to note that before agricultural innovation, our ancestors had high-protein, high-fat diets. Whey protein is very safe.
