⚠ Collagen-led protein

Collagen is the #1 protein ingredient. Collagen is an incomplete protein (no tryptophan, very low leucine) — a large share of the headline grams isn't doing muscle-building work. Legal and disclosed on the label; just know what you're paying for.

We check ingredient lists against known filler proteins — collagen, gelatin, and added free aminos like glycine or taurine. Collagen is legal and usually disclosed; this flag is about protein quality, not fraud.
