A MARINE FORMULA TO NOURISH YOUR JOINTS
As we age, cartilage renewal slows down, leading to stiffness and discomfort. CARTILAGE DE REQUIN has been formulated to bring the essential "bricks" for joint maintenance directly to the joints.
Unlike synthetic assemblies, we use a complete shark cartilage powder, naturally rich in Glucosamine and Chondroitin, guaranteeing optimal assimilation by the body.

FOCUS ON ACTIVE INGREDIENTS: A COMPLETE SYNERGY
Each ingredient has been selected for its precise role in the joint sphere:
🦈Shark (Dogfish) cartilage:
This is the "noble" raw material of this formula. It naturally contains Glycosaminoglycans (including Chondroitin and Glucosamine), major constituents of the cartilage matrix, essential for its suppleness.
🍈 SOD de Melon (Antioxidant):
Derived from a variety of French melon, this active ingredient provides Superoxide Dismutase (SOD), a powerful enzyme that helps protect joint cells against oxidative stress.
🍊 Vitamin C:
Indispensable for collagen synthesis, it ensures the normal functioning of bones and cartilage.
🦴 Vitamin D:
Helps maintain normal bone structure.
Composition for 3 capsules (Daily dose)
| Shark cartilage | 1200 mg |
| Melon extract (SOD) | 20 mg Melon extract |
| Vitamin C | 40 mg (50% AR*) |
| Vitamin D | 3 µg (60% RA*) |
