Marine Collagen vs Bovine Collagen

Both marine and bovine collagen are widely studied and considered high-quality sources of bioactive peptides that support skin, joints, and connective tissue health. While their origin and collagen type profiles differ, both are effective options depending on the desired benefit.

Source and Composition

• Bovine collagen is extracted from cow skin, bones, and connective tissues. It is rich in Type I and Type III collagen, with small amounts of Type II, making it supportive for skin structure, bone health, and overall connective tissue strength.
• Marine collagen is obtained from fish skin and scales. It is primarily Type I and  III collagen, which plays a major role in skin elasticity, hydration, and wound healing.

Absorption and Bioavailability

• Marine collagen peptides are generally smaller in molecular size, which may allow for faster absorption in the digestive tract.
• Bovine collagen is also highly bioavailable, with studies showing absorption rates of over 90% within hours of ingestion.

Practical Considerations

• Bovine collagen is widely available and often more cost-effective.
• Marine collagen is sometimes preferred by consumers seeking a pescatarian-friendly source or those focusing specifically on skin benefits.
