Magnesium deficiency is associated with poor physical performance, but no trials are available on how magnesium supplementation affects elderly people’s physical performance. The aim of our study was to investigate whether 12 wk of oral magnesium supplementation can improve physical performance in healthy elderly women.
Daily magnesium oxide supplementation for 12 wk seems to improve physical performance in healthy elderly women. These findings suggest a role for magnesium supplementation in preventing or delaying the age-related decline in physical performance. This trial was registered at clinicaltrials.gov as NCT01971424.
