Overview
•Whey Protein Concentrate is generally low-risk for healthy adults when used to help meet, not greatly exceed, daily protein needs.
•Contains milk and may cause bloating, gas, cramps, or diarrhea in people with lactose intolerance or sensitivity to dairy proteins.
•Some flavor and market variants contain soy lecithin, wheat, or are processed where eggs and gluten are handled; check the exact tub if allergic.
•People with kidney disease, severe liver disease, or medically restricted protein intake should use whey protein only with clinician guidance.
•Protein supplements can interfere with levodopa absorption in some people, and high-protein timing may matter for Parkinson’s medication plans.
