Whey Protein Concentrate, Unflavored
What this means
Elite efficiency — 40%+ of calories from protein. Lean meat, whey isolate, low-fat dairy. 73.8% density puts this in the Platinum tier.
Complete protein, high leucine, DIAAS > 1 — the muscle-protein reference.
Note: At 2.47g leucine per single scoop, this product sits below the 2.5g threshold needed to maximally trigger muscle protein synthesis in one serving. Common workarounds: use 1.5 scoops, or combine with another protein source in the same meal (e.g., Greek yogurt, eggs). More on the leucine threshold.

Notes
Informed-Sport certified. The direct concentrate counterpart to NOW's own whey isolate — same brand, same certification, same protein source, differing only in filtration format, which makes the pair the cleanest available isolate-vs-concentrate control. Leucine 2,472 mg per labeled 'typical amino acid profile (per serving)'.
