amofit S - Discover the Science of Better Sleep and Stress Relief
Why is stimulating the vagus nerve important?
The vagus nerve is a cranial nerve that originates in the brainstem and extends to major organs such as the heart, lungs, stomach, and intestines, playing a key regulatory role in the autonomic nervous system.
Vagus Nerve Stimulation (VNS) plays a crucial role in activating the parasympathetic nervous system and supporting systemic homeostasis.
Restores Autonomic Balance
Chronic stress or inflammation often leads to sympathetic dominance. VNS helps activate the parasympathetic system, restoring autonomic balance.
Anti-inflammatory Effects
VNS modulates the “inflammatory reflex,” reducing excessive immune responses and supporting patients with autoimmune or inflammatory conditions.
Improves Cardiovascular and Mental Health
VNS can enhance Heart Rate Variability (HRV) and positively influence mood disorders such as anxiety and depression.
A Non-Pharmacological Therapeutic Approach
VNS is being used as a non-invasive treatment option for conditions like depression, insomnia, and IBS, especially with the advancement of wearable technologies.
What is different?
Amofit S is an advanced neuromodulation device that stimulates the vagus nerve to help regulate and balance the autonomic nervous system.
Clinical (Scientific) Validation
While many products claim scientific backing, only a rare few have been scientifically validated through clinical trials.
amofit S has been rigorously validated through official clinical trials and peer-reviewed research, with the findings published in international scientific journals.
Innovative Bioelectronic Technology
This is a non-contact neuromodulation technology that has never existed before. Unlike conventional nerve stimulators, amofit S is effective within a 9-inch radius from the heart and maintains its full efficacy even when worn over clothing.
A Trusted User Experience
Over the past two years, more than 15,000 users have turned to amofit S to relieve and improve their symptoms. Clinical observations indicate that the more severe the symptoms, the greater the therapeutic effects experienced. While those with mild conditions may not notice significant changes, most individuals with severe symptoms report substantial improvements—often within just three days of use.
Human Safety
Based on the principle of bioresonance, amofit S gently stimulates the vagus nerve using ultra-low electromagnetic signals, unlike conventional devices that rely on strong electromagnetic or electrical stimulation. This approach is similar to natural nerve stimulation methods such as meditation or yoga, ensuring high levels of human safety without side effects.
Patents and Certifications
Our innovative bioelectronic medicine technology has been patented in 23 countries across the United States, Europe, and Asia, and is certified by major international standards including CE, FCC, KC, and RoHS.
Countries with registered patents include the United States, France, Italy, Sweden, Germany, Denmark, Belgium, Netherlands, Finland, Austria, Portugal, Bulgaria, Romania, Slovenia, Estonia, Lithuania, Luxembourg, Latvia, Malta, South Korea, Japan, China, and Taiwan.
Ease of Use
No more wearing bulky, heavy devices on your head, neck, or chest. Unlike conventional devices, Amofit S uses ultra-low electromagnetic signals, allowing for an ultra-compact design. It is the world’s smallest and lightest sleep enhancement device—conveniently worn as a necklace or clip. (3.9 x 3.9 x 0.8 cm, 14g)
Why to Choose?
01 How long should I use 'amofit S' for each day?
The standard usage time is 1 session (3 hours) for each mode per day. But for a higher effect, CALM Mode can be used for more than 2 sessions per day, while FOCUS Mode should not exceed 1 session per day. The minimum usage time is 30 minutes per day.
02 Who cannot use it? (Contraindications)
[Contraindication]
- Pregnant women
- People who have had an organ transplant
- Patients with epilepsy
- Children under the age of 5
- People with electronic or ferromagnetic implants (implantable devices)
※ Electronic implants: prosthetic heart valves, pacemakers, intrathecal pumps or insulin pumps, implantable defibrillator, etc.
※ ※ People with dental implants, nonmagnetic implants, or implants with weak magnetism (ex. artificial joint replacement, prosthesis, etc.) can use the device.
03 Do I wear 'amofit S' while sleeping?
No. Unlike other sleep-inducing products, 'amofit S' does not need to be worn while sleeping. You can wear it naturally in your daily life using a necklace string to wear around your neck or attach it to your clothes using the clip on the back of the device.
04 How do I change the mode on 'amofit S'?
'amofit S' provides 2 healing modes. After powering on the device, you can switch between CALM mode (for improving sleep and stress) to FOCUS mode (for enhancing memory and creativity) by pressing the touch area. You may attach the device to the collar using the clip on the device's back or use the necklace to wear it around your neck. The electromagnetic signal generated by 'amofit S' is effective within a 9-inch (23 cm) radius from the heart, so it can be worn conveniently over one’s clothing.
