Whey protein isolate and concentrate supplements have been safely used in doses up to 50 grams per day in studies. However, high doses may cause side effects like nausea, cramps, increased bowel movements, reduced appetite, fatigue and headaches in some individuals. People with lactose intolerance may also experience adverse effects.
Q: What are the side effects of whey protein?
A: The most common side effects of whey protein supplements include nausea, cramps, reduced appetite, diarrhea, fatigue and headaches. These side effects are usually mild and affect only a small percentage of users. High doses or using whey protein on an empty stomach may increase risk of side effects. Those with lactose intolerance are more prone to side effects.
Q: Is too much whey protein bad for your kidneys?
