Marine Collagen Peptides
Type I collagen from fish with smaller peptide size for superior absorption — proven benefits for skin hydration and wrinkle reduction.
Marine Collagen is derived from fish skin and scales, providing Type I collagen - the same type found in human skin. Due to its smaller peptide size, it has superior bioavailability compared to bovine collagen. Studies show significant benefits for skin hydration, elasticity, wrinkle reduction, and joint comfort. It's also a sustainable option from fish processing byproducts.
Signals fibroblasts to produce more collagen
Provides building blocks for collagen
Smaller peptides absorb better

5-10g daily
Loading: Not required; consistent daily use is key
Can be taken without food
| Form | Type |
|---|---|
| 🧪Hydrolyzed marine collagen powder | Recommended |
| 💊Capsules (need many for effective dose) | Alternative |
| 💧Liquid | Alternative |
Powder is most practical for the 5-10g needed. Look for sustainably sourced. Some have mild fishy taste.
Minimum: 8 weeks
Optimal: 24 weeks
Cycling: Not required
Note: Dissolves easily in hot or cold liquids. Timing doesn't matter much - consistency is key.
Firmer, more elastic skin
Visible reduction in fine lines and wrinkles
More hydrated, plump skin
Improved nail and hair quality
Avoid; use bovine collagen instead
Generally well-tolerated with medications; inform healthcare provider of all supplements
Tip: Mix with flavored beverages; choose quality products
Tip: Start with lower dose
