Collagen: Why Is It Essential?
Collagen is the most abundant protein in the human body, representing approximately 30% of all body proteins. This structural protein plays a fundamental role in the cohesion, strength, and elasticity of many tissues: skin, bones, cartilage, tendons, and ligaments.
According to INSERM , from the age of 25 , natural collagen production decreases by about 1% per year. This gradual loss leads to the appearance of wrinkles, a loss of skin firmness, and can contribute to joint pain. By age 40, we have lost about 15% of our collagen, and by age 60, nearly 40%.
This is why collagen supplementation in the form of a food supplement has become an essential beauty and wellness step to maintain the health of the skin, joints, hair and nails.

Our Difference: Two Exceptional Patented Collagens
At Delicure, we have selected two patented active ingredients that are among the most innovative on the collagen market. Each offers clinically proven benefits, with exceptional bioavailability and 100% French origin.
✓ Cartidyss® - Marine Collagen Type II
Origin: Skate cartilage caught in Brittany/Normandy
Type: Marine collagen Type II (rare on the market)
Format: 60 capsules (1-month course)
Dosage: 1g/day (2 capsules)
✓ Reggenerate™ - The Vegetarian Collagen
Origin: French egg membrane
Type: Vegetarian collagen (Types I, V, X)
Format: 60 sugar-free gummies, natural strawberry flavor
Dosage: 300mg/day (2 gummies)

Cartidyss®: Patented Type II Marine Collagen
A Rare and Highly Effective Collagen
Marine collagen type II represents only 10% of the global collagen market. Unlike type I collagen (the majority), type II is naturally concentrated in articular cartilage and offers remarkable effectiveness at low doses.
Our Cartidyss® collagen is extracted from the cartilage of rays caught off the coasts of Brittany and Normandy, guaranteeing complete traceability and locally sourced, eco-responsible fishing. The enzymatic hydrolysis process, without chemical solvents, yields pure and highly bioavailable collagen.
Unique Synergistic Composition
Beyond type II collagen, Cartidyss® naturally provides the following in each dose:
- Glucosamine : an essential precursor of glycosaminoglycans
- Chondroitin : a key molecule in cartilage, improving its strength and elasticity
- Hyaluronic acid : contributes to skin hydration and joint lubrication
This natural synergy makes Cartidyss® an "all-in-one" product that combines in a single capsule what would normally be taken separately.
Exceptional Clinical Results
Our Cartidyss® marine collagen has been the subject of several rigorous clinical studies , demonstrating its effectiveness on both skin AND joints:
On the skin (90-day study, 500mg/day):
- ✓ -25% facial wrinkles
- ✓ +38% dermal density (firmness)
- ✓ +10% dermal thickness
- ✓ Significant improvement in skin hydration
On the joints (90-day study, 1000mg/day):
- ✓ +35% improvement in joint mobility
- ✓ Pain reduction from the 1st month
- ✓ Protection of cartilage against degradation

Reggenerate™: The First Vegetarian Collagen in Gummies
A Unique Innovation in the World
Reggenerate™ is derived from the eggshell membrane, the thin layer located between the shell and the albumen. This natural source is the only one that provides genuine vegetarian collagen, unlike the "vegan collagens" on the market which do not actually contain collagen but only amino acids.
Our formula stands out thanks to its sugar-free gummy format, unique in the vegetarian collagen market. We use maltitol and sorbitol (polyols) which do not affect blood sugar levels and preserve dental health, while maintaining a delicious natural strawberry flavor.
Record Bioavailability of 85%
This is one of the most exceptional characteristics of Reggenerate™: its bioavailability of 85% , which is almost 3 times higher than classic marine or bovine collagens (30-50%).
According to a study published on PubMed , this exceptional bioavailability is explained by the naturally optimal molecular structure of the egg membrane, which does not require intensive hydrolysis. The active ingredients retain their integrity and natural synergy.
In practical terms: when you take 300mg of Reggenerate™, 255mg are actually absorbed by your body. With conventional collagen at 30% bioavailability, you would need to ingest 850mg to achieve the same result.
Naturally Complete Composition
The Reggenerate™ egg membrane naturally contains:
- 22% collagen (types I, V and X)
- 25% elastin : a key protein for skin elasticity
- 4% hyaluronic acid : skin hydration
- Glycosaminoglycans : chondroitin and glucosamine
9 Scientific Studies Validating the Effectiveness
Reggenerate™ is one of the most scientifically studied collagens, with 9 clinical studies including 3 randomized, double-blind, placebo-controlled trials:

- ✓ +66% skin firmness
- ✓ +25% elasticity
- ✓ -43% transepidermal water loss (better hydration)
- ✓ 78% of women noticed firmer skin
On the joints (30-day study, 300mg/day):
- ✓ -52% joint pain in just 30 days
- ✓ Visible results from day 3
- ✓ +48% improvement in joint function
- ✓ -9% cartilage degradation in 1 week
Regarding hair (12-week study, 300mg/day):

Why Take Collagen as a Dietary Supplement?
The Effectiveness of Hydrolyzed Collagen
When you consume collagen, it is broken down into peptides and amino acids by your digestive system. These elements are then absorbed and distributed throughout the body via the bloodstream.
Unlike cosmetic creams where collagen molecules are too large to penetrate the dermis, oral administration allows for systemic action throughout the body. Collagen peptides stimulate fibroblasts (collagen-producing cells) in the skin, as well as in the joints, tendons, and bones.
According to ANSES (National Agency for Food, Environmental and Occupational Health Safety), food supplements based on hydrolyzed collagen have a good safety profile at the recommended doses.
When to Start a Collagen Treatment?
Experts recommend starting collagen supplementation at age 25 , when natural production begins to decline. However, the benefits are noticeable at any age.
- 25-35 years : Prevention, maintenance of radiance and firmness
- 35-45 years old : First signs of aging, emerging wrinkles, joint comfort
- Ages 45-60 : Established wrinkles, loss of firmness, joint pain
- 60+ years : Maintaining mobility, preventing osteoarthritis
How long before I see the results?
Consistency is essential to achieving visible results:
- From 3 days : First effects on joint pain (Reggenerate™)
- After 1 month : Improved skin hydration, joint mobility
- After 2-3 months : Visible reduction in wrinkles, improved firmness
- After 3 months : Optimal results on skin, joints and hair
It is recommended to do treatments of at least 3 months , renewable 2 to 3 times a year to maintain the benefits.

Made in France: Our Quality Commitment
Our two collagens are 100% of French origin and manufactured in our laboratory in Toulon, guaranteeing total traceability and rigorous quality control.
Cartidyss®: Eco-Responsible Breton Fishing
The skate cartilage used is a by-product of local fishing in Brittany and Normandy. No fish are caught specifically for collagen; we simply utilize resources that would otherwise be wasted. This approach is part of an environmentally responsible circular economy.
Reggenerate™: French Hen Eggs
The egg membrane comes exclusively from French eggs , sourced from farms that adhere to strict hygiene and animal welfare standards. As with Cartidyss®, it is a by-product of the agri-food industry, valued within a circular economy framework.
Distributed in Over 800 Pharmacies
Our food supplements are available in over 800 pharmacies in France , a guarantee of quality and trust. We are also registered with the DGCCRF (French Directorate General for Competition Policy, Consumer Affairs and Fraud Control), making us one of the few CBD and food supplement brands to comply with all French regulations.
Collagen FAQ
This is generally not necessary as both products target the same benefits (skin + joints + hair). We recommend choosing one or the other based on your preferences (size, origin). However, there is no contraindication to using them together if you wish.
No, Reggenerate™ is vegetarian but not vegan, as it is derived from eggshell membrane. It is suitable for ovo-vegetarians. There is no such thing as true vegan collagen, as collagen is by nature an animal protein. Products sold as "vegan collagen" are actually collagen boosters (plant-based amino acids) that do not contain real collagen.
Yes, absolutely! Efficacy depends not on the format but on the quality of the collagen and its bioavailability. Our Reggenerate™ gummies have an exceptional bioavailability of 85% and are clinically proven (9 studies). The gummy format even offers advantages: better adherence (more pleasant to take), no aftertaste, and pre-measured dosage.
Type I collagen is the most abundant in the body, with a high concentration in skin, bones, and tendons. It therefore plays a major role in skin structure and firmness.
On the other hand, type II collagen — here presented via the patented Cartidyss® formula — stands out for its triple action: it supports joint health (mobility, comfort, cartilage), and thanks to optimized bioavailability and a synergistic supply (chondroitin, glucosamine, hyaluronic acid), it also acts on skin density, hydration and firmness.
In other words, in this version, you no longer choose "skin or joints", but a global "beauty + mobility" supplement.
Collagen is very well tolerated. Cartidyss® and Reggenerate™ have shown no adverse side effects in clinical studies. As a precaution, these supplements are not recommended for those under 18, pregnant or breastfeeding women (except on medical advice), or people allergic to fish (Cartidyss®) or eggs (Reggenerate™).
Collagen can be taken continuously at the recommended doses, as its natural production steadily declines with age. However, we recommend three-month courses, which can be repeated two to three times a year to maintain the effects. Results last for a few weeks after stopping, but gradually diminish if supplementation is not resumed.
Yes, it's even recommended! Vitamin C contributes to the body's normal collagen synthesis (claim validated by the EFSA ). Our collagen gummies are also enriched with vitamin C.
Hydrolyzed collagen (broken down into small peptides) is much more easily absorbed than native (non-hydrolyzed) collagen. Peptides with a low molecular weight (2000 daltons or less) cross the intestinal barrier more readily. This is why both of our collagens use hydrolyzed or naturally bioavailable forms.
