Performance / muscle
Research status · Dietary supplement
Dietary supplement (a food product, practically speaking).
A convenient way to close the gap to a daily protein target — especially useful when appetite is suppressed and whole-food volume is hard. Whey, casein, and plant blends all work; total daily protein matters most.
How it works
Supplies complete (or complementary) amino acids for muscle protein synthesis, like any protein food.
Commonly discussed use cases
- Hitting protein targets
- Muscle retention during weight loss
- Post-workout convenience
Supposed / potential benefits
- Makes daily protein targets much easier to hit
Common side effects
- Bloating with whey for the lactose-sensitive (isolate is gentler)
Warnings & contraindications
- It's a food-first gap-filler, not a requirement — quality varies between brands
Typical timing considerations
Whenever it helps you hit your target; post-workout or as a snack are common.
Administration route
Oral (shake)
Questions to ask your clinician
- What daily protein target do you recommend for me?
