Magnesium Sulfate (Epsom Salt)
Also known as: Magnesium Sulfate Cream, Magnesium Sulfate Heptahydrate
You’ve probably heard of this type of magnesium before, but by a different name. If you’ve heard of Epsom salt—that’s magnesium sulfate! It’s very similar in appearance and usage to magnesium chloride. Simply dissolve a cup or two of Epsom salt in a warm bath and soak. Bioavailability is lower with magnesium sulfate than with magnesium chloride. But that just means more bath time, right? Magnesium sulfate also provides sulfur, which may help soothe tired muscles. That makes Epsom salt popular among athletes looking to pamper sore or tired muscles from exercising.
