Seven Minerals Magnesium Oil Spray

The Pure Magnesium Oil formula is a water-based magnesium chloride solution, despite the word 'oil', and the brand lists USP-grade magnesium chloride as its only ingredient. The 12-ounce product page also identifies the spray as an external-use product, not an oral magnesium drink.

Spray a small amount on clean, dry skin, commonly on legs or other areas of muscle tension, and let it dry before rinsing if desired. The brand advises avoiding eyes, cuts, and freshly shaved skin, and starting with a small amount if your skin is sensitive.

No reliable answer should assume that it will, because evidence for raising whole-body magnesium through intact skin remains limited. Seven Minerals itself notes that topical use is not a proven substitute for oral supplementation, so people correcting a deficiency should ask a clinician about an appropriate oral form.

A concentrated magnesium chloride solution can feel salty, prickly, or irritating, especially on freshly shaved or damaged skin. Rinse it off and stop if irritation persists, and ask a clinician before use if you have kidney disease or another condition affected by magnesium.
