What it does
Benefits
- Convenient way to hit daily protein targets (0.7–1 g/lb bodyweight for active people)
- High leucine content triggers muscle protein synthesis
- Faster digestion than whole-food protein post-workout
- Supports satiety and body composition
The science
How it works
Dietary protein provides amino acids — the building blocks for muscle, enzymes, and hormones. Leucine in particular signals mTOR to initiate muscle protein synthesis. Whey is ~25% branched-chain amino acids and digests quickly.
Getting it right
Dose & timing
Dose guidance
20–40 g per serving, 1–2x per day. It's a protein supplement, not a meal replacement — prioritize whole-food protein.
Best time to take
Any time you need protein — post-workout, between meals, or as breakfast. Total daily protein matters most.

Common questions
FAQ
Do I need to drink it right after working out?
No — the anabolic window is 4+ hours wide. Daily total protein matters most.
Is whey safe for women?
Yes — whey is just filtered milk protein. No hormones, no masculinizing effects.
Concentrate or isolate?
Isolate if you're lactose-sensitive or cutting calories tightly. Otherwise concentrate is fine and cheaper.
