Marine Collagen — What It Is, Why It Works and How to Choose the Right One
Marine collagen — what it is, why it works and how to choose the right one
Marine collagen has become one of the most talked-about supplements in beauty and wellness — and for good reason. As we age, our natural collagen production declines, leading to visible changes in our skin, hair, nails and joints. The right supplement can help replenish what our bodies stop producing. But not all marine collagen is created equal. Here is exactly what to look for — and why Naticol® makes the difference.
What is collagen and why does it matter?
Collagen is the most abundant protein in the human body. It is a structural building block found throughout your skin, bones, muscles, joints, blood vessels and gut lining. It is what keeps skin firm and elastic, joints cushioned and comfortable, and hair and nails strong and resilient.
The challenge is that our bodies start producing less collagen from our mid-20s, with the decline accelerating dramatically through our 40s and 50s. The result:
- Sagging skin and visible wrinkles
- Thinning hair and brittle nails
- Stiff, aching joints
- Loss of bone density
While diet and lifestyle play a role, we cannot eat our way back to youthful collagen levels. The collagen molecules in whole food sources are too large for the body to absorb effectively. That is where hydrolysed collagen peptide supplementation comes in — and why the form of collagen matters so much. Read more in our complete guide to liquid marine collagen.
Why supplement with marine collagen?
A high-quality marine collagen supplement gives your body the specific amino acids it needs to support natural collagen production. Marine collagen has several key advantages over other sources:
- Smaller peptide size — easier for your body to absorb and use
- Type I collagen-rich — the most abundant type in skin, hair and nails
- Cleaner source — free from mammalian proteins
- More sustainable — when responsibly sourced from fishing by-products
Studies have shown marine collagen is absorbed up to 1.5 times faster than bovine alternatives, making it the preferred choice for visible results. Read our full marine vs bovine collagen comparison for a detailed breakdown.
What is Naticol® marine collagen?
Naticol® is a premium, clinical-grade marine collagen developed by French ingredient specialists Weishardt. It is the marine collagen used in every Kollo product — and there is a reason we will not compromise on it.
Sustainably sourced
Naticol® comes from the skins and scales of aquaculture-farmed fish — by-products of the food industry that would otherwise go to waste. No fish is caught specifically for collagen production.
Pure and clean
Unlike collagen from cattle or chicken, Naticol® is free from common contaminants, hormones and growth additives. It is also free from GMOs, fat, carbohydrates, preservatives and purine.
Backed by human clinical studies
This is what sets Naticol® apart. It has been the subject of multiple human clinical studies — not test-tube experiments, but real research on real people. Those studies were conducted at a 10,000mg daily dose, which is exactly what you get in every Kollo serving. Most cheaper brands dose at a fraction of that.
Highly bioavailable
Naticol® is enzymatically hydrolysed — broken down into ultra-small peptides — so it is effectively pre-digested. Your body can absorb and use it immediately, without putting strain on your digestive system.
What makes Kollo different?

- 10,000mg of Naticol® marine collagen — the exact dose used in clinical studies
- 100% RDA of Vitamin C, B1, B5, B6 and B12 — to support natural collagen synthesis
- L-Lysine — an amino acid that promotes collagen growth and supports the immune system
Our products are made in the UK, Informed Choice certified for purity, quality and banned and illegal substances, and tested for heavy metals and allergens. We are the UK's most awarded liquid collagen brand, trusted by over 7,000 five-star reviewers.

How to get the most from your collagen
Supplementation works best alongside healthy habits. To support your body's natural collagen production:
- Wear sunscreen daily — UV exposure is one of the fastest drivers of collagen breakdown
- Eat a nutrient-rich diet — antioxidants help protect existing collagen from degradation
- Avoid smoking — it dramatically accelerates collagen loss through oxidative stress
- Move regularly — exercise supports circulation and reduces cortisol
- Sleep 7 to 9 hours a night — collagen synthesis ramps up while you rest
Most people see visible improvements in skin hydration, hair strength and nail growth within 4 to 8 weeks of consistent daily use. Joint benefits typically follow at 8 to 12 weeks. Read the full clinical timeline in our guide to how long marine collagen takes to work.
