Hydrolyzed Collagen Peptides

Also known as: Marine Collagen Peptides, Fish Collagen Hydrolysate, Collagen Hydrolysate, Tilapia Collagen

B
Evidence

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.
