Vitamin D Disappoints in Knee Pain

A small randomized, double-blind clinical trial exploring the effects of Vitamin D supplements on pain in adults with knee osteoarthritis (OA) has yielded disappointing results. After two years, the supplement group and placebo group showed no difference in knee pain, function, or loss of cartilage volume. Maybe two years was not long enough, but more research is needed.

PositiveTip: Save your money. Daily moderate physical activity is probably more helpful in preventing knee OA pain than Vitamin D supplements.
