A Transformative Method to Boost Your HRV

Numerous studies found HRV to be a sensitive predictor of a higher risk of adverse cardiovascular events and all-cause mortality. By uncovering the complex relationships between the nervous system and heart rhythm, HRV reveals key characteristics of our cardiovascular resilience. 

Vagus nerve stimulation is an FDA-approved somatic treatment for various pathologies. In clinical studies, neuromodulation was confirmed to be an effective approach for rebalancing the nervous system, improving HRV, and improving overall cardiovascular health.

Clinical Data & Patient Results

Nurosym improved all HRV parameters of the autonomic function response by 61%.

Results that make a difference.

In a placebo-controlled trial, Nurosym has demonstrated a significant increase in heart rate variability over placebo across all three parameters of HRV. 

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). 

HRV is an indicator of Vagus Nerve activity. Improving these parameters of HRV indicates targeted stimulation of the vagus nerve and activation of specific mechanisms that reverse chronic fatigue, improve cardiovascular function, and improve overall quality of life.

With 30+ clinical trials, Nurosym has proven to be an effective solution for boosting HRV.

I have been using Nurosym to improve my low HRV. I am seeing the first sign of improvements after two weeks of use. It has been very easy to implement the device into my daily routine as it is both easy to navigate and well-designed. Customer service has been very responsive to solve any issues I had. Can recommend!

I used the Nurosym for several months now once a day. This led to a dramatic increase in HRV from the mid-40s back to the mid-80s to mid-90s where I was before my burnout.


It's an amazing product. Honestly, I've seen such a huge difference. I don't have as many days when I'm so exhausted I can barely move. I feel like I have more of my weekends back and feel better overall.

After a couple of weeks I suddenly realized, "I feel like me again." The depression has lifted and I have the get up and go. Thank you folks :)

Nurosym FAQs

How long should I use Nurosym each day for optimal HRV results?

Based on research findings and patient feedback, we recommend 30-60 mins once to twice a day to increase HRV, but longer stimulations are possible if someone feels comfortable with it.

For accurate tracking of progress, we recommend using a real-time HRV tracker (Ultrahuman, HeartMath). Then sit or lie down without movement for 15 mins and breathe in a stable, consistent way. Turn Nurosym on and find your energy level. Try to focus on the breath and let go of your thoughts. Continue for 15-30 mins. Repeat the experiment at least 10-20 times with Nurosym and 10-20 times without Nurosym. Note down the time you started and finished. Note down HRV values in 1-minute increments. Take an average from the session and your max values. Repeat for each experiment. Then take an average of averages from Nurosym vs non-Nurosym experiments to see the difference. 

Do I need a prescription to purchase Nurosym?

No. However, we recommend that you consult with your doctor if you’re unsure whether Nurosym is right for you.

Is Nurosym safe?

Yes, neuromodulation via Nurosym is considered safe when used as intended. Be sure to read the important safety information before use.

Heart Rate Variability (HRV) is a Key Biomarker for Overall Health.

HRV is a measure of the variation in time intervals between consecutive heartbeats. It provides vital insights into the balance of the autonomic nervous system and indicates how well your body responds to stress and recovers from it. 

HRV tracking offers invaluable insights into your body’s stress response, recovery, and overall health. By monitoring your HRV, you can optimize your fitness routine, manage stress effectively, and stay ahead of chronic diseases. 

Wearable health trackers like Whoop, Oura, Fitbit, Garmin––or the more accurate Heart Math device––can help you track and understand your HRV levels. However, the complexity of HRV means you can’t rely 100% on the reported statistics from these wearables.

How Vagus Nerve Function Impacts HRV.

The vagus nerve is the main communication pathway between the brain and major bodily organs. It activates the "rest and digest" response through the parasympathetic nervous system, aiding in efficient energy conservation. However, this balance can be disrupted by excessive stress and inflammatory responses, potentially lowering your HRV and decreasing your body’s ability to handle stress over time. 

Vagus nerve function plays a crucial role in regulating HRV through its parasympathetic influence on the heart and cardiovascular function. 

Additionally, the vagus nerve is also involved in regulating emotions. Since emotional states dynamically impact HRV levels, promoting a state of calmness in the nervous system has a positive impact on HRV. 

Understanding this mechanism is a breakthrough in understanding the complex impact of HRV on well-being, providing new possibilities for people looking to enhance their HRV and optimize their overall health. 

The good news?

It’s now possible to reliably boost your HRV right from your own home.

Neuromodulation is a proven method to boost HRV.

As supported by numerous doctors and research groups, Neuromodulation is a groundbreaking technology that presents a new era of health optimization.

By sending targeted signals to specific neural circuits through the vagus nerve, it’s possible to change your body’s physical and mental state and improve your overall quality of life. In addition, vagus nerve stimulation has been shown to trigger the body’s natural “rest-and-digest” response, which increases HRV, slows the heart rate, and promotes relaxation.  

Similar to how cardiac pacemakers regulate heart rhythms, neuromodulation works by restoring the normal functioning of the nervous system.

After spending years in development alongside the world’s leading clinical research centers, we’ve created the breakthrough product that’s been missing – a safe, easy, cost-effective home therapy device that allows you to optimize your HRV and bring your body back to balance.

Autonomic Tone and Heart Rate Variability are Important Indicators of Your Health – Here is Why

The results speak for themselves.

We are constantly upgrading our mobile phones, computers, and cars to better versions. But what about new and different ways to support well-being? Vagus nerve stimulation offers an interesting new opportunity here. In preliminary N=1 experiments with Nurosym for vagal neuromodulation, I have seen possible beneficial effects on parasympathetic activation during stimulation, which can be seen as the main switch on recovery.


For me, it is a groundbreaking tool for both wellness and performance enhancement.

The benefits I've experienced include a measurable reduction in stress, improved recovery metrics as measured by my WHOOP device, and an increased ability to focus or train for long periods of time.
