Cartilage in joints serves as a padding to prevent bones from constantly rubbing against each other. Cartilage does not contain blood vessels and nutrition is supplied via the synovial fluid. As a consequence it only receives limited oxygen and regenerates very slowly, if at all.

Researchers from the University of Freiburg (Germany) showed that NADH works like a vacuum cleaner sucking oxygen into the tissue twice as fast as under normal circumstances. Hence NADH increases the oxygen supply in the tissue and improves the regeneration of defective cartilage cells.

NADH in combination with the cartilage-regenerating substances glucosamine and chondroitin helps repair cartilage. Chondroitin protects cartilage from drying out and makes it more elastic. Glucosamine is needed for building and repairing cartilage. NADH increases the oxygen supply.
