Can too much protein cause gas?

Yes, consuming excessive protein can indeed lead to gas or "protein farts." This issue arises not necessarily from the protein itself but from digestive problems that can occur when one's digestion is not handling the protein consumption well. Factors such as intolerance to certain types of protein (like whey), consuming protein in excessive amounts, or poor digestion can contribute to this problem 1 2 3.

It's suggested to examine the source of the protein—whether it's from supplements like protein powders or certain food items that might not be digested well—and to consider adjusting intake or switching to different sources that are easier on the digestion. For some, using proteins that are easier to digest, like collagen from bone broth, might be beneficial, particularly for those with sensitive digestion 4.

Additionally, consuming protein from whole foods rather than large amounts of supplements and ensuring a balanced intake with other nutrients like fibers can help mitigate digestive issues related to high protein consumption 5.
