What Is Marine Collagen, and Why Is It in Every FLW Drink?

FLW Blog August 12, 2026 4 min read

Marine collagen comes from fish — unlike the more common bovine collagen. Every FLW can contains 1000mg of hydrolyzed marine collagen peptides, and here's what that actually means.

Why "marine" specifically?

Marine collagen is extracted from fish, and it's one of the most common collagen sources in supplements alongside bovine collagen. The core difference between them isn't really "effectiveness" so much as the source — which matters directly to anyone with an allergy or a dietary restriction.

What does "hydrolyzed" mean?

Hydrolysis is a process that breaks large collagen molecules into much smaller peptides. These smaller peptides are easier for the body to absorb compared to the whole, unprocessed collagen molecule — which is why most modern collagen products, FLW included, use the hydrolyzed form.

Why in a drink, not a powder or capsules?

The liquid format means more convenience: no mixing, no powder that dissolves poorly, no pills to swallow. Here, collagen works alongside electrolytes, vitamins and prebiotics as part of one comprehensive hydration formula — not a separate supplement added to your routine.

Important if you have allergies Since it's fish-sourced, FLW contains a known allergen (fish). If you have a fish allergy, we recommend avoiding this product.
