Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Vitamin D is scientifically validated as a nutrient important for muscle health. Numerous studies have established that vitamin D receptors are present in muscle tissue, and vitamin D plays a direct role in muscle cell growth and function. Deficiency in vitamin D has been associated with muscle weakness, increased risk of falls, and impaired muscle performance, especially in older adults. Randomized controlled trials have shown that vitamin D supplementation can improve muscle strength and balance in individuals who are deficient, thereby reducing fall risk. However, the effect of supplementation in people with sufficient levels of vitamin D is less clear, and some studies report little benefit in these populations. Meta-analyses generally support the benefit of vitamin D for muscle function in the context of deficiency, but not necessarily for the general population. Overall, the evidence strongly supports the use of vitamin D to support muscle health in individuals at risk for or with documented low vitamin D status, although routine supplementation for muscle support in the general population is less well established.
