What magnesium oil actually is
01
Magnesium chloride you spray on
"Magnesium oil" isn't really an oil — it's a concentrated magnesium chloride solution that feels silky. You spray or rub it onto your skin rather than swallow it.
02
A topical, gut-friendly ritual
People like it because there are no tablets and no laxative effect — just a quick spray on the legs after exercise or before bed, often as part of a wind-down.
03
The honest bit
How much magnesium your skin actually absorbs is genuinely debated. We'll walk you through what the research says so you can decide with your eyes open.
