Higher magnesium intake linked to lower muscle loss risk in older adults, study finds

Older adults who consume sufficient magnesium face a lower risk of sarcopenia, the age-related loss of muscle mass and strength, according to a study published in the journal Frontiers in Nutrition. The study found that participants with the highest magnesium intake had a 53 percent lower risk of muscle loss compared with those in the lowest intake group. Researchers said the link between magnesium and muscle health held even after accounting for factors such as age, physical activity level, body mass index, and protein and calorie intake. The researchers suggested that lower levels of C-reactive protein, a marker of chronic inflammation, among those with higher magnesium intake may help explain the effect. Magnesium, a mineral that supports muscle and nerve function, has also been associated with reduced muscle cramps and improved sleep quality, the study said. Experts warned, however, that taking magnesium supplements without medical supervision could cause side effects. The findings underscore the role of a balanced diet that includes natural sources of magnesium and regular exercise in preserving muscle strength in older age.
