- Bovine Hydrolysed Peptides
- 2,000–5,000 Da
- 95%
- High. Pro-Hyp and Hyp-Gly detected in plasma 30–60 min post-ingestion
- 10–15g
- Highest bioavailability for dermal collagen synthesis. Most clinical trials use bovine peptides
- Marine Hydrolysed Peptides
- 90%
- High. Similar plasma dipeptide profile to bovine
- Equivalent efficacy to bovine but often 40–60% more expensive per gram
- Porcine Hydrolysed Peptides
- 92%
- High. Bioavailability comparable to bovine
- Less common in supplements but mechanistically equivalent
- Bone Broth (Intact Protein)
- >10,000 Da
- 60–70%
- Low. Peptides too large for intact absorption
- Not applicable
- Nutritionally valuable but does not deliver bioactive dipeptides to dermal tissue
- Gelatin (Partially Hydrolysed)
- 5,000–100,000 Da
- 85%
- Low to moderate. Requires further enzymatic digestion
- 15–20g
- Less efficient than fully hydrolysed peptides. Requires higher dose
- Collagen Builders (Amino Acids)
- N/A
- None. No Pro-Hyp dipeptides
- Individual amino acids do not replicate the signaling function of collagen-specific dipeptides
