Neuro Duo 4 + Vagus (2 devices)
USD$3,098.00
When used in combination, the Neuro Duo 4 and the Vagus create a powerful photobiomodulation system that stimulates both the brain and vagal nerve. This enhances brain and systemic performance while improving brain-body connectivity.
Vielight technology quality is guaranteed by medical-grade certification.
We can provide free consultation both before and after your purchase.
Description
The Neuro Duo 4 helps you improve your cognition, memory and functional connectivity. Its Alpha mode induces a more relaxed mental state, while its Gamma mode induces a more focused mental state.
The Vagus was engineered to enhance brain-body connectivity and improve the brain-gut connection. Vagus nerve stimulation also promotes changes in the brain’s structure and function.
Using both devices together helps you with:
- 20 minutes per session
- Results in 4 to 8 weeks
- Adjustable and comfortable

The Neuro offers a nasal gateway to the brain
The Vielight Neuro also offers patented intranasal photobiomodulation technology.
This is the best way to deliver near-infrared energy through the nose to the underside of the brain.
- The olfactory bulb is directly connected to the brain regions responsible for keeping long-term memories.
- The ventromedial prefrontal cortex is vital for cognitive processes
Using both devices together helps you with:
- Focus
- Systemic fitness
- Memory
- Anxiety & Stress
- Sleep quality
- Mental clarity
- Brain energy
- Creativity
- Immunity
These products come with…
- Medical-grade technology
- Used by everyday people, researchers and elite athletes
- 2-year warranty and 6-month return policy

How it Works
The Neuro Duo 4 has 5 Vie-LED modules that emit pulsed 810nm near-infrared light to stimulate the brain cells without generating heat. Our design efficiently produces the highest amount of power in the market (~300 mW/cm2 irradiance, 1000 mW per transcranial LED, 5000-6000 mW total). See 3rd-party testing report.
The Vagus comes with an intranasal applicator that is inserted in the nasal cavity. It also comes with 2 bilateral neck modules that sit on the left and right sides of the neck. Its flexible steel band accommodates different neck sizes.
