Curated, not stocked.
We recommend this for patients who need magnesium support but find oral forms hard on the digestive system. The combination of magnesium chloride with OptiMSM — a distillation-purified form of MSM — reflects a deliberate formulation choice rather than a marketing one. Ancient Minerals has a credible reputation for purity in the topical magnesium category, and this product earns its place on that basis.
About this product
Magnesium Oil Ultra w/ OptiMSM®
Ancient Minerals Magnesium Oil Ultra is a topical magnesium spray combining magnesium chloride with OptiMSM, a highly refined grade of methylsulfonylmethane. Applied directly to the skin, it delivers magnesium transdermally — bypassing the digestive tract, which can limit absorption from oral supplements and cause loose stools at higher doses. MSM is a naturally occurring sulphur compound that is studied for its role in supporting connective tissue, joint comfort, and post-exercise recovery.
This formula suits people who struggle to tolerate oral magnesium, those looking to support muscle recovery after training, and anyone wanting a targeted, direct application to specific areas of tension or discomfort. It fits neatly into an evening wind-down routine or a post-exercise protocol.
Magnesium chloride is one of the more bioavailable forms of magnesium used in topical applications, and Ancient Minerals is a brand with a long-standing focus on sourcing high-purity magnesium from ancient geological deposits. OptiMSM is a specific branded form of MSM manufactured via a proprietary distillation process, which is why it warrants the name — not all MSM is produced the same way. Together, these two ingredients make a considered pairing for musculoskeletal and recovery support.

Common questions
Frequently asked
How does topical magnesium compare to taking an oral supplement?
Oral magnesium can cause loose stools at higher doses, which limits how much some people can take. Applying magnesium chloride to the skin bypasses the digestive tract entirely. The extent of transdermal absorption is still an active area of research, but many people find topical application a practical and well-tolerated alternative or complement to oral forms.
What is OptiMSM and why does it matter?
OptiMSM is a branded, distillation-purified form of methylsulfonylmethane (MSM). MSM is a sulphur-containing compound studied for its role in supporting joint comfort and connective tissue. The distillation process used for OptiMSM is intended to produce a purer end product compared to standard crystallisation methods.
Will it leave a sticky or white residue on the skin?
Some people notice a light residue or tingling sensation after applying magnesium oil, which is normal. Rinsing the skin 20–30 minutes after application can reduce any stickiness while still allowing absorption time — though check the packaging for the brand's specific guidance.
Is this suitable for sensitive skin?
Magnesium chloride can cause a mild tingling or temporary redness in some individuals, particularly on sensitive or freshly shaved skin. It is worth patch-testing on a small area first. If irritation persists, avoid broken or inflamed skin and consult a pharmacist or clinician.
Can I use this alongside oral magnesium supplements?
Many people use topical magnesium alongside an oral supplement without issue. If you are managing a specific health condition or taking prescribed medication, it is worth checking with your GP or pharmacist before combining the two.
