Supplements cannot purport to cure, treat, mitigate, or prevent disease. The NutraJoint Pitch. NutraJoint is being marketed to people whose joints are stressed by vigorous exercise or excess weight and to those who are experiencing joint wear due to age. The assumption is that if you supplement your diet with gelatin, you will consume more of these amino acids, and this will help rejuvenate your joints. Vitamin C is a free radical fighting antioxidant.
Free radicals are destructive molecules produced in the body by a chemical process called oxidation.
The idea here it that NutraJoint will reduce the free radicals in your body and thus lessen cartilage damage. As cartilage deteriorates, the underlying bone can break down. Taking more calcium by consuming NutraJoint will slow the progression of this bone loss. The NutraJoint web site refers to several laboratory studies, some animal research, and a few small human clinical trials from Europe to support the product claims. There is apparently no hard scientific evidence, from replicated, double blind human studies, showing that NutraJoint works.
