Where Can I Buy Epsom Salt?

Pharmacies, grocery stores and dollar stores carry Epsom salt. Do make sure that the only ingredient in the package is magnesium sulfate. Sometimes Epsom salt is packaged as a single use bath additive which also contain essential oils or other ingredients. Epsom salt products with added ingredients should never be used internally.

Epsom Salt Side Effects

Epsom salt is used as a laxative, so naturally, more Epsom salt than your body needs can give you loose stools. Oral doses are more likely to cause loose stools, though in sensitive people, an Epsom salt bath can cause the same effect.

Other side effects from Epsom salt include dizziness, low blood pressure, nausea, and hives.

To reduce your risk of side effects, start with a smaller dose and increase the amount you use slowly if needed. If you do get loose stools, cut back on the amount you take until you are relieving yourself at a comfortable rate.
