The particles in Epsom salt are supposed to absorb in your skin providing the body with magnesium and sulfates. But the truth is there is no scientific evidence that reveals that magnesium or sulfates actually absorb into your body through the skin.
The magnesium that is used in Epsom salt is used to manage constipation. Magnesium is mostly taken by mouth for constipation relief and how this happens is it pulls water into your colon while promoting bowel movements.
There is anecdotal evidence that shows that Epsom salt baths can reduce muscle soreness from exercise performance and recovery. Relaxing in a hot bath with Epsom salt can help you soothe and relieve aching muscles based on anecdotal evidence.
There is no validated research that shows when you take an Epsom bath that the magnesium in it absorbs in your skin. Many people have reported via anecdotal evidence that Epsom baths can improve symptoms of fibromyalgia and arthritis.
How to create an Epsom salt bath is the following:
- Add two cups of Epsom salt in water in a normal size bathtub and then soak your body for about 15 minutes.
- Epsom salt can also be taken by mouth in a laxative.
- Many brands recommend you take 2 to 6 teaspoons dissolved in water which is the maximum for adults or 1 to 2 teaspoons for children.
The Bottom Line is Epsom salt, a compound made up of magnesium, sulfur, and oxygen. It’s a compound similar to table salt that is dissolved in a standard size bath to help with aches and soreness as a recovery technique from exercise performance.
