gammacore

How It Works

The vagus nerve is the longest cranial nerve in the body. It travels from the brainstem through the neck and into the chest and abdomen, playing a key role in regulating:

• Nervous system balance

• Inflammatory response

• Digestive signaling

• Heart rate variability

• Stress adaptation

During treatment, gammaCore® is placed on either side of the neck where the vagus nerve is accessible. The device delivers proprietary, controlled electrical stimulation through the skin, activating vagal pathways and signaling the brain.

This process supports communication between the brain and body — without surgery, implants, or medication.

FDA Clearance (United States)

gammaCore® is FDA-cleared in the U.S. for the treatment of certain headache disorders, including migraines and cluster headaches.

Additional approvals for other indications exist in Europe and other regions.

Any other uses discussed within a functional medicine setting are considered off-label and should be guided by a qualified healthcare provider.

Vagus nerve tone plays a foundational role in regulating:

• Stress response

• Digestive function

• Mood balance

• Inflammatory signaling

• Autonomic nervous system resilience

In clinical settings, vagus nerve stimulation may be incorporated into comprehensive wellness plans to support nervous system regulation.

Patients commonly explore vagus nerve support in contexts such as:

• Stress-related symptoms

• Digestive discomfort

• Autonomic imbalance

• Mood regulation support

• Relaxation practices

• Meditation enhancement

Use should always be guided by a healthcare professional.

Non-Invasive & Drug-Free

gammaCore® offers:

• Non-invasive stimulation

• No surgical implantation

• No systemic medication

• At-home usability (with provider guidance)

It provides a structured, measurable way to engage the vagus nerve as part of a personalized care plan.

Who May Benefit from Vagus Nerve Support?

The vagus nerve plays a central role in the parasympathetic nervous system — often referred to as the “rest and restore” pathway. Supporting vagal tone may be considered in individuals experiencing nervous system imbalance or stress dysregulation.

Your provider can determine whether gammaCore® is appropriate for your care plan.

Support Your Nervous System at the Source

The vagus nerve influences many systems in the body — including neurological, digestive, and stress-response pathways. gammaCore® offers a clinically studied, FDA-cleared option for non-invasive stimulation as part of an integrative approach to care.
