What sets this marine collagen apart is its tripeptide form. Unlike standard hydrolysates, whose molecular weight often exceeds 3,000 daltons, Naticol® 3XPeptide tripeptides have a molecular weight below 1,500 daltons. This smaller size makes it far easier to cross the intestinal barrier, allowing the peptides to reach the deeper layers of the skin directly.

Glycine-proline-hydroxyproline (GPH) tripeptides make up at least 25% of the formula — the three amino acids that form the basic building blocks of the body’s own collagen. Because they are supplied already in this structured form, the body can use them without an extra breakdown step, which explains the fast results seen from the first weeks of use.

Clinical studies in adult women show that a daily intake of 1 to 2.5 g of tripeptide marine collagen significantly improves skin hydration within the first four weeks; close to 84% of users report softer, better-hydrated skin after one month of use. Fine lines and firmness show more visible improvement after 8-12 weeks of continued use.

Beyond the skin, marine collagen tripeptides also help maintain the structure of cartilage and tendons, offering useful support for joint flexibility for athletes and active people, alongside a balanced diet and regular exercise.

Take 2 to 4 capsules a day (625 mg each), ideally on an empty stomach or between meals. At 2 capsules a day (1 g of collagen), the goal is daily maintenance and hydration; at 4 capsules a day (2.5 g), the focus is a more intensive anti-ageing effect on wrinkles and elasticity. First effects are noticeable from 4 weeks; an 8-12 week course is recommended for optimal results, and can be repeated several times a year. Pairing intake with vitamin C (fruit or a supplement) supports the body’s natural collagen synthesis.

Not recommended for people with a fish allergy. If pregnant or breastfeeding, seek medical advice before use. Suitable for children over 3 (open the capsule and mix the contents into food). Do not exceed the recommended daily dose. Store in a cool, dry place away from light. Keep out of reach of young children. A food supplement is not a substitute for a varied, balanced diet and a healthy lifestyle.

At what age should I start a marine collagen course?

Natural collagen production starts to decline around age 25-30, accelerating after 40. A tripeptide marine collagen course can be considered as soon as the first signs of skin slackening or unusual dryness appear. Between 30 and 40, the goal is mainly preventive (2 capsules a day); after 40, a higher dose (4 capsules a day) is generally recommended.

How long before I see the first results?

The first improvements are usually noticeable after 4 weeks of daily use, particularly better hydration and a more radiant complexion. For more pronounced effects on wrinkles and elasticity, continuing for 8-12 weeks is recommended; results build up the longer the course continues.

Can marine collagen be combined with other supplements?

Pairing it with vitamin C is particularly effective, as it supports the body’s own collagen synthesis. Hyaluronic acid and omega-3s are also good companions for an overall skin-beauty routine. Our team at Herba Barona in Paris 12 can help you find the right combination for your needs.
