Topical Mag provides magnesium sulfate—also known as Epsom salts. It has been used for years in bath salts to soothe sore feet and muscles.* Research into the use of transdermal magnesium sulfate is in the early stages but studies suggest regular application can raise magnesium levels and help restore magnesium status. Magnesium sulfate also has many clinical uses via oral application, including treating magnesium deficiency, pre-eclampsia in pregnant women, arrhythmias, and asthma.
