Key Benefits
- Relaxes muscles and eases tension.
- Supports detox and cleansing.
- Calms the nervous system.
- Softens and nourishes the skin.
Serotonin Soak Jar combines pure Zechstein magnesium flakes with apple cider vinegar and skin-softening algae to transform an ordinary bath into a restorative ritual. It has magnesium to relax sore muscles and support detoxification, while apple cider vinegar helps balance and refresh the skin. Infused with natural algae, it nourishes and remineralises, leaving the skin soft and revitalised after every soak.
It features pure essential oils that elevate the bathing experience, creating a calming, spa-like atmosphere that helps ease the nervous system and promote restorative sleep. With 100% natural ingredients and no artificial fragrances or chemical additives, Serotonin Soak Jar offers a clean, gentle option suitable even for sensitive skin.
Why HigherDOSE is Healf
Serotonin Soak Jar uses Zechstein magnesium, a natural and responsibly sourced mineral drawn from the ancient Zechstein seabed. Unlike Epsom salts, which are often manufactured and may contain fragrances or allergens, Zechstein magnesium remains pollutant-free and safe for those sensitive to sulphur. Its higher bioavailability allows the body to absorb it more effectively, making it a cleaner and more beneficial choice for relaxation, detoxification, and skin nourishment.

Wow
Omg I don’t think I can put into words how amazing this made me feel, I’ve never felt more relaxed after a bath than I have using these flakes. I actually felt high when I went to my bed I was that chilled n I fell straight asleep n woke up feeling like I’d just had a massage. All the tension I had been feeling in my muscles was gone. I was having quite an anxious week n felt on edge n all my worries n nerves drifted away as soon as I lay in the bath, I had a deep thought bathing experience n everything just felt amazing. I couldn’t recommend this product enough.

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!
Janet
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.
