R(h)ein Nutrition®
Joint food

The joint food capsules from R(h)ein Nutrition® contain collagen, glucosamine sulphate, chondroitin sulphate and hyaluron as well as vitamin C, vitamin K2 and vitamin D3. They are combined in a well-balanced ratio in order to optimally supplement the diet. Human joints consist of bones, cartilage and connective tissue.

It is also ideal for people on a vegan diet. Taking the capsules is very easy. 2×4 capsules per day are sufficient to supply the body with vital nutrients. R(h)ein Nutrition, based in Cologne on the Rhine, produces high-quality food supplements. The ease of use makes it a convenient choice. The product is vegan and free from unnecessary additives.
