Can whey protein cause headaches?

There is limited research on the relationship between whey protein and headaches, but some individuals may experience headaches as a side effect of consuming whey protein. This can be due to various factors such as sensitivity to the ingredients in the protein powder, dehydration, or a rapid increase in protein intake.

One study published in the Journal of the International Society of Sports Nutrition found that individuals who consumed whey protein in conjunction with resistance training reported no adverse effects, including headaches, compared to those who consumed a carbohydrate-based placebo. However, this study only included a small number of participants, and more research is needed to establish a clear link between whey protein and headaches.

It's important to consult with a healthcare professional if you are experiencing frequent or severe headaches after consuming whey protein, especially if you have any underlying health conditions. Additionally, it's always best to drink plenty of water and monitor your overall protein intake to avoid any potential negative effects.
