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.
Why Ancient Minerals is Healf
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.

Ingredients
Approximately 15g elemental magnesium and 3g elemental sulfur (from OptiMSM®) per cup.
Suggested use
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.

The best wellbeing website…
The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.

Amazing!
Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!

Great products, service, and customer support
Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf
It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
