Magnesium Sulfate
What is Magnesium Sulfate?
Magnesium sulfate is a mineral compound made of magnesium, sulfur, and oxygen typically found as Epsom salt. It is commonly produced by combining magnesium oxide and sulfuric acid.
In personal care products, magnesium sulfate is used for its properties as an exfoliant and to provide relief from muscle aches. Research shows it can have varied effects on health, as it is crucial for many bodily functions, but its topical application has limited absorption.
When you see magnesium sulfate on a product label, it is often used for textural enhancement or therapeutic purposes rather than nutritional supplementation.
Commonly found in: sunscreen, bath salts, lotions, creams, personal care products
Benefits

Magnesium sulfate is approved as safe by the FDA for use in pharmaceutical and cosmetic products.
Research supports its use for muscle relaxation, but the efficacy of absorption through the skin is debated.
Magnesium sulfate is mineral-based and suitable for vegan use.
