Key Benefits
Ancient Minerals Magnesium Bath Flakes Ultra combine pure Zechstein magnesium chloride with OptiMSM®, a premium source of organic sulphur. This blend is designed for easy absorption, offering a convenient way to top up your magnesium levels while you relax in the bath.
Magnesium is an essential mineral that contributes to a reduction of tiredness and fatigue, supports normal muscle function, and helps maintain healthy bones and teeth. It also plays a role in the normal functioning of the nervous system and supports normal psychological function.
Whether you’re easing into your evening or looking to support your muscles after activity, adding magnesium to your bath can help you feel more at ease and ready for what’s next.
Inspired by ancient bathing traditions, these bath flakes offer a modern way to enjoy the benefits of topical magnesium. Simply dissolve in warm water and let your body soak up the goodness—no pills or fuss required.
Ancient Minerals centres around one of the most essential—and most commonly deficient—minerals in the modern world: magnesium. Built on the research of Dr. Mark Sircus and a foundation of transdermal science, the brand has become a trusted name for therapeutic-grade magnesium care.
Sourced from the ancient Zechstein seabed, their products deliver high-purity magnesium through the skin, bypassing the digestive tract for faster absorption. Whether in oil, flakes, or lotion form, each application offers a gentle but potent way to restore mineral balance and support everything from sleep to muscle recovery.
With our Healf Curation Process, we do the work for you. Shop with confidence knowing that every item has been tried, tested, and curated for you.

Genuine Zechstein magnesium chloride flakes (and trace minerals), methylsulfonylmethane (MSM), vegetable glycerin
Approximately 15g elemental magnesium and 3g elemental sulfur (from OptiMSM®) per cup.
Dissolve 1-3 cups of magnesium flakes into a warm foot bath or full tub bath and soak for 30 minutes or more.
Dissolve up to 8 lbs of magnesium flakes in a full tub bath for intense applications.
The temperature of the water should be warm, but not hot. Hot water causes the skin to eliminate rather than absorb.
Following the bath, rinse skin with cool running water, then pat skin dry with a towel and apply a natural moisturiser.
