Curated, not stocked.
Oral magnesium is well established, but transdermal delivery offers a genuinely useful alternative for those who experience gastrointestinal sensitivity at therapeutic doses. Ancient Minerals has earned a strong reputation in this category through the quality of its Zechstein-sourced magnesium chloride and a formulation philosophy that avoids unnecessary additives. We stock it because it is one of the cleaner, better-sourced options in a market that is otherwise inconsistent.
About this product
Magnesium Oil Original - Spray Bottle
Ancient Minerals Magnesium Oil Original is a topical magnesium chloride spray designed to deliver magnesium directly through the skin. Despite the name, it contains no oil — the term refers to the slick, oily texture that a concentrated magnesium chloride solution produces on contact with skin. Transdermal application bypasses the digestive tract entirely, which may suit people who find oral magnesium supplements cause loose stools at the doses they need.
Magnesium is involved in hundreds of enzymatic processes: muscle contraction and relaxation, nerve signalling, and normal energy metabolism. Applying it topically to areas of tension — calves, shoulders, the soles of the feet — is a practical way to incorporate magnesium into a recovery or wind-down routine.
This spray is well suited to athletes managing muscle fatigue, people who struggle with oral supplementation, or anyone looking to support relaxation before sleep. It fits easily into an evening routine applied after a shower, when the skin is warm and pores are open.
Ancient Minerals sources its magnesium chloride from the ancient Zechstein seabed in the Netherlands, a deposit formed over 250 million years ago and considered exceptionally pure due to its geological isolation. The formulation contains no synthetic additives beyond the active ingredient, keeping it straightforward for those with sensitive skin or a preference for minimal ingredient lists.

How to use
Spray directly onto clean skin — common sites include the legs, arms, abdomen, and soles of the feet. Leave on for at least 20 minutes before rinsing if desired. A mild tingling sensation is normal, particularly on freshly washed or sensitive skin; diluting with water or applying after moisturiser can reduce this.

Common questions
Frequently asked
What does 'magnesium oil' actually mean — is there oil in it?
No. The product contains no oil. Magnesium chloride in a concentrated solution has a slick, oily feel on the skin, which is where the name comes from. The formula is simply magnesium chloride and water.
Why might I choose a topical spray over an oral supplement?
Oral magnesium, particularly at higher doses, can cause loose stools in some people. Applying magnesium transdermally bypasses the gut entirely, which may allow you to achieve your target intake without that side effect. It is also easy to apply directly to areas of muscular tension.
Is the tingling sensation normal?
Yes, a mild stinging or tingling is common, especially on freshly washed or sensitive skin. It typically fades with regular use. Diluting the spray with a little water, or applying it over a light moisturiser, can reduce the sensation.
When is the best time to apply it?
Many people apply it in the evening after a shower, when skin is warm and circulation is good. Applying to the legs and feet before bed fits naturally into a wind-down routine and may support relaxation and sleep quality.
Who might want to avoid this product?
Those with broken, irritated, or very sensitive skin should patch-test first, as the concentrated solution can cause discomfort. If you have a kidney condition that affects magnesium excretion, speak to your GP before adding any magnesium supplement — topical or oral.
