What Is Marine Collagen and Why Take It Orally?

Marine collagen, derived from fish skin and scales, is a type I collagen known for its high bioavailability compared to bovine or porcine sources. Unlike topical creams that sit on the skin's surface, oral intake allows marine collagen to be absorbed into the bloodstream, delivering amino acids like glycine and proline directly to cells for repair and regeneration. This process supports skin elasticity, joint health, and hair strength as natural collagen production drops by 1% annually after age 20, per British Skin Foundation 2025 data. In the UK, where beauty and wellness trends drive demand, oral marine collagen is preferred for its systemic benefits, making it a top choice for anti-aging and recovery.

Why Oral Marine Collagen Outshines Other Methods

Superior Bioavailability

Oral marine collagen is broken into small peptides during digestion, enhancing absorption (up to 90% bioavailability) compared to topical collagen (minimal penetration) or bovine collagen (larger molecules, lower uptake). A 2019 study showed 2.5g daily of hydrolysed marine collagen improved skin elasticity by 7% over 8 weeks, a result unattainable with creams.

Targeted Cellular Benefits

When taken orally, marine collagen peptides stimulate fibroblasts and chondrocytes, promoting collagen synthesis in skin, joints, and connective tissues. Topical applications lack this systemic reach, while oral intake supports deeper tissue repair, including hair and nails. SellHealth UK's REJUVE BIO-X combines this with NAD+ to enhance cellular energy.

Proven Efficacy

Clinical evidence supports oral marine collagen's effectiveness. A 2020 trial found 2.5g daily increased hair thickness by 15% and reduced nail brittleness by 42% over 3 months, outcomes tied to oral absorption. Topical or other sources lack similar data, reinforcing oral marine collagen's superiority.

Why Avoid Non-Oral Marine Collagen?

• Topical Limitations: Creams and serums offer surface hydration but don't penetrate to stimulate collagen production, with studies showing minimal impact on aging.
• Injections Risks: Collagen injections, though effective for wrinkles, carry risks like allergic reactions or lumps, and aren't practical for daily use.
• Other Sources: Bovine or porcine collagen, often in non-oral forms, has lower bioavailability and may contain hormones or allergens, unlike marine's purity.

Oral marine collagen, like SellHealth UK's REJUVE BIO-X, avoids these pitfalls with safe, effective delivery.

Benefits of Oral Marine Collagen

Research and user feedback highlight:

• Skin Elasticity: 7% improvement in 8 weeks with 2.5g daily.

SellHealth UK's REJUVE BIO-X maximises these with hydrolysed marine collagen.
