Overview
Seven Minerals' Pure Magnesium Oil is a topical spray of USP-grade magnesium chloride, sold in a 12 oz bottle with about 33,000 mg of magnesium, mined in the US and marketed for muscle, sleep and restless-leg use.
This is a topical spray applied to skin, most commonly feet or sore muscles, not an oral supplement, which is a meaningful difference from tablet or capsule magnesium products in the same category. The USP-grade and pharmaceutical-grade labeling refers to the magnesium chloride's purity standard rather than a certified drug status. It's marketed toward sleep, cramps and restless legs, common uses for topical magnesium, and is gluten free, vegan and vegetarian.
