Understanding Collagen Types: Differences Between Marine, Bovine, and Fish Collagen

Collagen is the most abundant protein in our body and contributes to the normal function of skin, cartilage, bones, and connective tissue. When choosing a collagen supplement, there are important differences to understand between the various sources.

MARINE COLLAGEN

Marine collagen is derived from fish and marine organisms and is known for its small molecular size (low molecular weight). This can be important for bioavailability. Marine collagen primarily contains Type I collagen, which is concentrated in the skin, hair, and nails.

BOVINE COLLAGEN

Bovine collagen is extracted from bovine bones and cartilage. It mainly contains Type I and Type III collagen and offers a broad spectrum of amino acid profiles. Bovine collagen is a traditional source with a long history in nutrition.

FISH COLLAGEN

Fish collagen is similar to marine collagen in its composition and bioavailability. It is often obtained from fish by-products and is a sustainable option.

SCIENTIFIC BASIS

Studies suggest that collagen peptides (hydrolyzed collagen) are better absorbed than non-hydrolyzed collagen. The peptides are broken down into smaller amino acids, which can support absorption in the gastrointestinal tract.

CHOOSING THE RIGHT FORM

The best collagen form for you depends on your personal goals and preferences:

• Marine collagen: For those who prefer a light, fast-absorbing option
• - Bovine collagen: For a complete amino acid profile
• - Hydrolyzed collagen: Regardless of the source, for optimal bioavailability

QUALITY AND SUSTAINABILITY

When making your choice, look for high-quality sources that offer purity and transparency of origin. Many modern collagen products adhere to strict quality standards and can be verified through test reports and certifications.
