Frequently Asked Questions

Vagus nerve stimulation activates your vagus nerve, the longest cranial nerve in the body, to support a balanced nervous system. Truvaga vagus nerve stimulators access the vagus nerve via the neck, just 1.5cm beneath the surface of the skin. Learn more about the science behind Truvaga and vagus nerve stimulation here.

Truvaga 350 is drug-free and has no known interactions with with any other prescribed or over-the-counter medication. You should always consult with your physician before starting vagus nerve stimulation.

The duration of each session is two-minutes. For optimal results, we recommend performing 1 session in the morning and another before bed. However, if needed, it’s safe to use up to 24 sessions per day.

You should feel a gentle tingling sensation on the neck where your Truvaga device is being held. You may also feel a downward pulling on your lip; this is the most common muscle contraction seen with use and indicates you’re in the correct position. You control the intensity level up or down at any time. Sessions should never be painful.

While many experience a downward lip pull, it’s not necessary in order to receive the full benefit from vagus nerve stimulation.

Vagus nerve stimulation results will vary by individual. For optimal results, consistent use is essential.  Some people may experience noticeable effects relatively quickly, while others may require 2-3 weeks of consistent use.

It is safe to travel with all Truvaga devices. Because the product contains lithium batteries, we recommend storing it in your carry-on luggage to ensure it is not exposed to extreme conditions. One container of conductive gel or spray is within the TSA liquid carry-on regulation.

Truvaga differs from a TENS unit in several key aspects. First, Truvaga is built on patented technology, setting it apart. One significant distinction in the technology lies in the waveform used—Truvaga technology employs smooth sine waves instead of block waves, providing a gentler experience for users. Truvaga devices also eliminate the need for electrode pads, offering a more convenient and user-friendly application compared to TENS units.

No, Truvaga devices are intended for use on the neck, where the vagus nerve is located and can be properly reached. We have not performed clinical testing on any other part of the body.

Anyone with an active implantable medical device, such as a pacemaker, hearing aid implant, or any implanted electronic device. For complete warnings and precautions, check out the product user manuals on our support page.

Truvaga 350 provides safe and well-tolerated non-drug therapy. The technology is backed by robust scientific and clinical research, supporting its effectiveness and safety. Most side effects are mild, occur only while using the device, and disappear shortly after each session.

In clinical studies, less than 5% of participants experienced mild side effects, including but not limited to:

-Application site discomfort, irritation, or redness
-Muscle twitching and/or contractions
-Localized pain in the face, head, or neck (including toothache)
-Mild headache
-Mild dizziness
