Key Benefits
amofit S uses advanced bioelectronic technology to stimulate the vagus nerve and promote balance within the autonomic nervous system. It delivers low-frequency electromagnetic signals that help the body manage stress, improve sleep quality, and enhance mental clarity. The device operates through AMO Lab’s proprietary cVES (cervicothoracic vagus electromagnetic stimulation) technology, which targets the vagus nerve in the chest using gentle electromagnetic waves similar to the body’s own natural signals.
The device features two modes—CALM and FOCUS—designed to regulate vagal tone and support specific needs. CALM mode helps ease stress and supports restful sleep by activating the parasympathetic nervous system. FOCUS mode promotes creativity and concentration by encouraging alpha brainwave activity.
Lightweight and compact, amofit S measures just 3.9 x 3.9 x 0.8 cm and weighs 14 g. Its necklace-style design allows easy, comfortable use throughout the day, providing an accessible way to maintain nervous system balance and mental wellbeing.

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.
