Top picks by evidence
- Low evidence4 studies
Across 4 studies, 2 reported moderate beneficial effects of whey protein on handgrip strength, while 2 found no significant benefit (small neutral effects). The evidence is mixed, primarily in older adults and clinical populations. No consistent dose or duration was reported.
- 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.
