M Marine Collagen

An alternative approach with distinct characteristics.

Best For:

  • Better absorption
  • Pescatarian-friendly
  • Smaller molecules

What Is Collagen?

Collagen is the most abundant protein in your body, making up about 30% of your total protein content. It's the primary structural component of your skin, bones, tendons, ligaments, and other connective tissues.

As you age, your body produces less collagen—approximately 1% less each year after your mid-20s. This decline contributes to visible signs of aging like wrinkles, sagging skin, and joint stiffness. Collagen supplements aim to support your body's collagen levels by providing the amino acids (primarily glycine, proline, and hydroxyproline) needed for collagen production.

Research has shown that hydrolyzed collagen peptides can improve skin hydration, elasticity, and reduce the appearance of wrinkles after 8-12 weeks of consistent supplementation.

What Is Marine Collagen?

Marine Collagen refers to a specific type or source of collagen. Different collagen types (I, II, III, etc.) are found in different tissues and may offer targeted benefits.

Understanding these differences can help you choose the right collagen product for your specific health goals.

Key Differences

Can Combine? Yes, they complement each other

When to Choose Collagen

Collagen may be the better choice if your primary goals include:

  • Skin health: Improving skin hydration, elasticity, and reducing fine lines
  • Joint support: Supporting joint comfort and mobility
  • Hair and nails: Strengthening brittle nails and supporting hair health
  • Gut health: Supporting the gut lining and digestive health
  • Overall connective tissue: Supporting tendons, ligaments, and bones

When to Choose Marine Collagen

Marine Collagen may be the better choice if your primary goals include:

  • Better absorption
  • Pescatarian-friendly
  • Smaller molecules

Can You Take Both Together?

Yes! Collagen and marine collagen can be taken together safely.

Note: Yes - they provide complementary collagen types

The Verdict

Both collagen and marine collagen can be valuable additions to your wellness routine, but they serve different purposes.

Choose collagen if you're primarily focused on skin health, joint support, hair and nail strength, or overall connective tissue health. Collagen provides the specific amino acids your body uses to build and maintain these tissues.

Choose marine collagen if your primary goals align more with its key benefits: better absorption and pescatarian-friendly.

Consider taking both if you want to address multiple health goals. Many people successfully combine collagen with marine collagen as part of a comprehensive supplement routine.
