Magnesium deficiency is associated also in the elderly with low physical performance; nevertheless trials about the effect of supplementation of magnesium on physical performance are not available in old people. The aim of our study is to investigate whether 12-weeks of oral magnesium supplementation improves physical performance in healthy elderly women
