Protein Powder Side Effects: Acne, Bloating, and Kidney Myths
Dr. Circuit|

The Short Answer
No, protein does not kill your kidneys (unless you have pre-existing disease). Yes, Whey can cause acne in some individuals due to IGF-1 spikes.
Q: Why do I get bloated?
Bloating usually comes from Lactose Intolerance or cheap artificial sweeteners (Maltitol). Switch to a Whey Protein Isolate (which removes lactose) or a high-quality Vegan blend.
Q: Does protein cause acne?
Dairy-based protein (Whey/Casein) increases insulin-like growth factor-1 (IGF-1), which can trigger sebum production. If you break out, try Beef Isolate or Pea Protein.
