How does Nurosym Work
The Mechanisms of Nurosym Neuromodulation
Nurosym sends patented electrical impulses to the brain via the Vagus Nerve, with clinical trial results showing:
61% increase in Vagus Nerve Activity & improved Heart Rate Variability
- Stress
- Depression, Anxiety
- Insomnia
- Athletic recovery
- Ageing & Longevity
The parasympathetic nervous system is the body’s internal relaxation & rest mechanism. HRV is an indicator of Vagus Nerve activity. Improving these parameters of HRV indicates targeted stimulation of the vagus nerve and activation of specific self-repair mechanisms of body & mind.
In a clinical trial, a one-hour session of Nurosym favourably altered all three parameters of Heart Rate Variability (HRV), when compared to a placebo.
Figure (a) shows High Frequency HRV is significantly increased ('p=0.001). Figure (b) shows Low-Frequency HRV is significantly decreased ('P=0.001). Figure (c) shows the ratio of LF to HF is significantly decreased (*p=0.002).

In a study of patients experiencing chronic fatigue symptoms after Covid-19 infection, approximately 40% of the participants showed positive responses to treatment involving Nurosym neuromodulation, as evidenced by improvements in fatigue, brain fog, and widespread pain. Improvement in long COVID symptoms, such as persistent fatigue, brain fog, and respiratory issues, can enhance quality of life and reduced disability.

- Muscle Pain
- Chronic Pain
- Cardiac Conditions (AF, HF, Hypertension)
- Mental Health
- Autoimmune Disorders
- IBS & Other GI Symptoms
Inflammation throughout the body and brain contributes to disease development, progression, ageing, and mental health problems. In a randomised controlled trial of Nurosym neuromodulation, inflammatory cytokines were significantly lower in the group that received Auricular Vagal Neuromodulation Therapy (AVNT) compared to the placebo group at the end of 3 months.

40% reduction in POTS symptoms
- Decreased inflammation
- Improved heart rate & rythm regulation
- Recuded risk of cardiovascular complications
- Post-trauma recovery
- Arrhythmias mitigation
- Oxygen level increase
After two months of using Nurosym therapy, the active group experienced a significant reduction in postural tachycardia syndrome (POTS) compared to the sham group, as observed through heart rate variability analyses. Additionally, the active group showed lower levels of anti-autonomic autoantibodies (specifically α1-AR and β1-AR), indicating a potential improvement in autonomic function and a reduction in inflammation.

50% improvement in blood vessel flexibility & improved circulation
- Oxygen and nutrient delivery to tissues
- Organ function
- Blood clots risk reduction
- Varicose veins
- Vascular disease risk reduction
- Fatigue
Nurosym has demonstrated the ability to enhance blood circulation compared to a placebo.
This improvement in blood circulation, or perfusion rate, is crucial for efficiently supplying oxygen and nutrients to tissues while removing waste products.
Such enhancements contribute to overall health and longevity by optimizing blood supply to various organs.

61% increase in Vagus Nerve Activity & improved Heart Rate Variability
Heart Rate Variability (HRV) is a biomarker of Parasympathetic “rest and digest” system activation, indicating a balanced nervous system often associated with increased vagus nerve activity. In clinical trials, a one-hour session of Nurosym favourably altered three key parameters of Heart Rate Variability (HRV), when compared to placebo. These findings indicate an activation of the parasympathetic 'rest and digest' system, coupled with a decrease in the 'fight or flight' response.
Health implications:
- Stress
- Anxiety
- Exercise recovery
- Longevity
- Dysautonomia

Figure (A) shows High Frequency HRV is significantly increased (*p=0.001). Figure (B) shows Low Frequency HRV is significantly decreased (*P=0.001). Figure (C) shows the ratio of LF to HF is significantly decreased (*p=0.002). It suggests a greater shift towards the parasympathetic side during Nurosym neuromodulation, indicating a more pronounced relaxation response.
(Figure A, B, C, D) The autonomic function response, Nurosym Neuromodulation favourably altered all HRV parameters (A: HF, B: RMSSD, C: pRR50, D: SDRR). Better effects were observed in people with a poorer baseline HRV ratio. Memory effect was observed, meaning HRV remains elevated after neuromodulation was stopped.
