At a glance
Insufficient
evidence for magnesium on the skin (oils, sprays, flakes, lotions)
Our honest take
Magnesium chloride bath flakes, sold for soaking after exercise. A warm bath can feel good after training, but there is little good evidence that a useful amount of magnesium passes through the skin, and claims about muscle recovery from bath flakes are not authorised. Think of this as a pleasant bath product rather than a way to raise your magnesium; if you want more magnesium, food or an oral supplement is the route with evidence behind it.
- You enjoy a long, warm bath after training and want something to add to it
- You understand it is a bath product, not a proven supplement
- You want to raise your magnesium intake: an oral supplement is the proven route
- You have broken or irritated skin
- You have a heart condition or are pregnant: check with your GP or midwife before long hot baths
The science
Magnesium on the skin (oils, sprays, flakes, lotions)· evidence: Insufficient
Magnesium sprays, oils, lotions and bath flakes are usually magnesium chloride (or sulfate) in water. They are sold on the idea that magnesium soaks in through the skin. Reviews of the research have found very little good evidence that a meaningful amount does: the skin is a strong barrier, and the few small studies are poor quality and inconsistent.
A warm bath or a massage may feel good in its own right, but if you want to raise your magnesium intake, magnesium from food or an oral supplement is the route with evidence behind it. Claims about sleep, muscles, joints or stress for these products are not authorised.
Typical dose: No established dose. Use as directed on the pack.
Safety: Magnesium chloride sprays often tingle or sting, especially on freshly shaved or broken skin; rinse off if irritation persists. Do not swallow. Keep away from eyes.
