Liquid Magnesium Supplements

Why choose liquid

Liquid magnesium skips the pills — you mix it into water or juice, or take it straight from a spoon, and you can fine-tune the amount to suit you. That makes it a good fit for anyone who finds capsules hard to swallow, and for children who can't take pills at all.

The forms

Liquid magnesium comes in several forms: glycinate and bisglycinate are gentle on the stomach; citrate is well absorbed (though at higher doses it can loosen the stools); ionic liquids are highly dilute and mix cleanly; and L-threonate is the form most studied for the brain. You'll also find calcium-magnesium blends that pair the two minerals together.

Magnesium oil and sprays

"Magnesium oil" isn't actually an oil — it's a concentrated magnesium chloride solution that feels oily on the skin. It's applied topically as a spray or rubbed in, a transdermal alternative to swallowing magnesium. For the cream and lotion versions, see our magnesium lotion page.

Liquid magnesium for kids

Liquids and drops suit children who can't manage capsules, which is why parents often choose this format. Children's magnesium needs are much lower than adults', so look for a product made for kids and follow its age-based dosing rather than splitting an adult dose. See our magnesium for kids page, and keep all supplements well out of reach.

Magnesium can interact with some medications — if you take any, check with your pharmacist, and space magnesium a few hours apart from your other pills.
