  • Low evidence4 studies

    Across 4 studies, 1 reported a beneficial small-sized effect of Vitamin D on handgrip strength, while 3 found neutral effects. The beneficial finding came from a small 8-week RCT in postmenopausal women with low vitamin D levels, but larger and longer studies (median duration 576 days) in broader populations (sarcopenia patients, athletes, elderly) consistently showed no significant improvement. The evidence primarily draws from trials using vitamin D3, with doses up to 2000 IU/day in the longest study, but no clear effective dose range emerged.
