Marine Collagen vs Bovine Collagen: Which Is Better in 2026?

If you're choosing a collagen supplement, you've likely come across two main types: marine collagen and bovine collagen. But which one is actually better?

In this guide, we break down the key differences, benefits, and which type of collagen is best for your goals.

What Is Collagen?

Collagen is the most abundant protein in your body. It supports:

Skin elasticity

Joint health

Hair and nail growth

Gut health

As we age, collagen production declines — which is why many people turn to collagen supplements.

What Is Marine Collagen?

Marine collagen is sourced from fish and contains primarily Type I collagen, the most abundant collagen type in the human body.

Key benefits of marine collagen:

High absorption rate

Supports skin hydration and elasticity

Ideal for anti-aging

Because of its smaller peptide size, marine collagen peptides are easier for your body to absorb.

What Is Bovine Collagen?

Bovine collagen is derived from cows and contains Type I and Type III collagen.

Key benefits of bovine collagen:

Supports joints and bones

More affordable

Widely available

Marine Collagen vs Bovine Collagen: Key Differences

Feature | Marine Collagen | Bovine Collagen
Source | Fish | Cow
Collagen Type | Type I | Type I & III
Absorption | Higher | Moderate
Best For | Skin, anti-aging | Joints, overall health

Which Collagen Is Better?

Choose marine collagen if you want:

Better skin results

Faster absorption

Anti-aging benefits

Choose bovine collagen if you want:

Joint support

General health benefits

Lower cost

Why Absorption Matters

The effectiveness of collagen depends on how well your body absorbs it.
Hydrolysed collagen peptides, especially from marine sources, are broken down into smaller molecules, making them easier to use.

Final Verdict

Both types of collagen have benefits, but marine collagen is often considered superior for skin health and absorption, while bovine collagen is better for joint support.
