Description:
Kayyali discusses Muir et al's study determining the effects of vitamin D on muscle strength, balance, and gait, as well as the optimal vitamin D dosage, in the older adult population. The studies analyzed were published between 1980 and 2019. All six trials evaluating vitamin D supplementation at 800 IU or more per day showed statistically significant positive changes in balance and muscle strength. Only one study showed a positive effect on balance when a single large dose (600,000 IU) of vitamin D was administered. No significant effects on gait were found in any of the studies. The meta-analysis focused on the physical performance outcomes body sway and the Timed Up and Go test, both measures of balance, and the knee-extension test, which relates to leg strength.
