How do I choose a protein product — and what should it actually do?
Shelf order follows evidence and leucine density together: NOW's whey isolate leads as the gold standard (the trial form, the fast absorption, the 2.7 g leucine per scoop that triggers in one serving), Truvani's plant blend is the honest vegan route (complete via the blend strategy, leucine-checked), and collagen closes as the structural adjunct with its not-an-MPS-trigger caveat built into the tag. All three sit behind the food-first pattern they supplement. The products below are educational examples — not medical recommendations.

by NOW Sports · Whey Protein Isolate
The form with the strongest MPS evidence: whey isolate — fast-absorbing, ~11% leucine by weight (the trigger amino acid), lactose-reduced (isolate vs. concentrate), and the trial material for most of the muscle-protein-synthesis literature. 25 g per scoop with ~2.7 g leucine clears the MPS threshold in one serving. Well tolerated; mild GI in the lactose-sensitive is rare with isolate. Not for CKD patients without nephrologist-set targets.
