Every lifter has come across this statement– ‘Whey protein causes kidney stones’. Does this actually stand true or is it just bro-science? Well, to start with, you need to understand what whey protein is. Whey proteins are categorized as 1st class protein by the scientist as it contains 70-90% proteins with all essential amino acids. These stimulate protein synthesis. They work like normal proteins but in a more effective and accelerated manner.
Bro-Science 1: Whey Protein Causes Kidney Stones
Let’s be logical, if whey protein was the reason for kidney stones, stone treatment centers would get influx of patients who are bodybuilders. That’s exactly not the case. The logic is simple: if you already have unhealthy kidneys, something most people aren’t even aware of, in that case, excess protein can harm. This is the reason why supplement brands ask users to consult a physician before consuming anything. So, it’s basically your existing issue that is creating the problem and not the supplement!
Our body is smart enough to identify the macro and micro nutrients. Protein, be it from the supplements or food, is treated the same way. As a matter of fact, our body needs protein more than any other macro-nutrient. It helps regulate metabolism, support the bodily systems, bolsters the immune system and helps form blood cells. If you work out regularly, you need additional protein to repair the damaged tissues and to retain muscle mass. Supplementing with whey protein not only helps cover up the protein deficiency, but it also fulfills the immediate protein requirement after your workout.
Bro-Science 2: Whey Protein Hikes Uric Acid

Now this is another misconception ruling most of the brains out there. This is true that the end product of protein is urea, which determines the uric acid level. However, there is no concrete evidence that shows that whey protein leads to increase in the uric acid. The only protein sources that you need to avoid in the case of uric acid excess is red meat and leafy vegetables as they contain purine, which is a compound that leads to uric acid formation.
Therefore, follow the real science and train smart, because bro-science only leads to misconceptions.
Have a great training day!
