Joint/Skin
Hydrolyzed Collagen Peptides
Also known as: Marine Collagen Peptides, Fish Collagen Hydrolysate, Collagen Hydrolysate, Tilapia Collagen
Hydrolyzed collagen peptides are bioavailable collagen fragments that may support skin elasticity, joint health, and connective tissue integrity. Evidence supports benefits for skin hydration and joint function, though marine sources are less studied than bovine counterparts.
Primary uses
- Skin health and elasticity
- Joint support
- Connective tissue integrity
- Bone health
- Hair and nail support
How it works
- Provides bioavailable amino acids (glycine, proline, hydroxyproline) for collagen synthesis
- May stimulate fibroblast activity and collagen production
- Supports extracellular matrix composition
Dosage
- Typical range
- 5-20 grams daily
- Timing
- Consistent daily intake; timing relative to meals is not critical
- With food
- May be taken with or without food; taking with vitamin C may support collagen synthesis
- Duration
- Benefits typically observed after 4-12 weeks of consistent use
- Special populations
- Safe for most adults; pregnant/nursing women should consult healthcare provider; pescatarians/vegetarians may have concerns with fish sourcing
Forms
- Powder· 70/100
- Capsules· 70/100
- Liquid· 70/100
Safety
Common side effects
- Mild digestive upset (rare)
- Fishy aftertaste (powder form)
- Bloating (uncommon)
Contraindications
- Fish/seafood allergy
- Phenylketonuria (PKU) if containing certain additives

Evidence notes
Good evidence exists for hydrolyzed collagen peptides on skin hydration and elasticity from multiple RCTs; joint support evidence is moderate but promising. Marine-specific sources have less clinical data than bovine collagen, warranting B rather than A grade.
Grade B: Some human trials support key claims; further confirmation needed.
