Collagen (Hydrolyzed) for Wound Healing
Collagen peptides supply useful amino acids but do not beat adequate protein.
Overview
Verdict
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- No oral dose established; studied at 10-15 g/day with inconsistent results
- Expected timeframe
- Not established
Protocol
- dose
- 10-15 g/day used in small pressure-ulcer and post-surgical studies
- form
- Hydrolysed collagen peptides or collagen-containing oral nutrition supplements
- steps
- The evidence here is insufficient. Small trials of 10-15 g/day of collagen peptides in pressure ulcers and surgical wounds report faster closure, but they are few, small, often industry-funded, and usually give collagen inside a mixed nutrition supplement containing protein, arginine, zinc and vitamin C — so the collagen contribution cannot be isolated.,The nutrients with real wound-healing evidence are total protein intake (1.2-1.5 g/kg/day), zinc if deficient, and vitamin C if deficient. Address those first.,Topical collagen dressings are a separate, better-evidenced product and are not the same as swallowing collagen.,Any non-healing or infected wound needs clinical assessment, not a supplement.,If you still want to try oral collagen, 10-15 g/day is the studied range, but treat it as unproven adjunct only.

Evidence
What the studies say
No studies are yet linked to both Collagen (Hydrolyzed) and Wound Healing.
Safety
Caveats
Do not delay medical care for a non-healing, infected or diabetic foot wound. Collagen is an incomplete protein and cannot meet the protein demand of healing on its own. Fish allergy risk with marine sources. Not studied in pregnancy.
