What the AI looks for in Collagen Supplements
- Hydrolyzed form
- Labelled as hydrolyzed collagen or collagen peptides. Peptides dissolve easily and are the form used in most skin and joint research.
- Daily amount
- Studies on skin generally use roughly 2.5 to 10 g of peptides per day. Capsules often deliver far less than a scoop of powder.
- Type matches goal
- Types I/III for skin; undenatured type II (very small doses) is a separate product for joints. Undenatured type II works differently and is not a substitute for peptide powder.
- Contaminant testing
- Prefer brands with third-party heavy-metal testing. Animal-derived powders can carry heavy metals.
Brands that matter
- Vital Proteins: Most widely available peptide powder.
- Sports Research: Value peptides.
- Ancient Nutrition: Multi-source blends.
- Orgain: Collagen peptides in mainstream retail.
What to avoid
- "Vegan collagen" products, which contain no collagen
- Gummies with small doses and lots of sugar
- Counting collagen toward protein goals; it lacks tryptophan
