Choose gammaCore Sapphire CV

Choose gammaCore Sapphire CV if you have a diagnosed migraine or cluster-headache condition and a prescriber willing to write for it — the only FDA-cleared non-invasive VNS device.

Choose Truvaga 350

Choose Truvaga 350 if you want the gammaCore hardware platform without the prescription gate — same 5 kHz cervical waveform, sold over-the-counter as a wellness device.

Choose Pulsetto

Choose Pulsetto if you want the most accessible consumer cervical tVNS — neck collar with four guided programmes (sleep, stress, anxiety, pain) at the lowest price.

The short version

Three regulatory tiers on the same vagal-trunk target. gammaCore for clinical headache patients; Truvaga for consumers wanting the gammaCore platform without prescription; Pulsetto for the most accessible consumer cervical tVNS at the lowest price.

When is gammaCore Sapphire CV the right pick?

If you have a diagnosed migraine or cluster-headache condition and a prescriber willing to write for it, gammaCore is the right tool. The FDA clearance and 30+ randomised trials are the regulatory value. Wrong shape for general wellness.

When is Truvaga 350 the right pick?

If you want the gammaCore hardware platform — same 5 kHz cervical waveform, same manufacturing pedigree — without going through a clinician, Truvaga is the right shape. The wellness indication is consumer-direct; the clinical evidence is for the platform, not Truvaga’s labelling.

When is Pulsetto the right pick?

If you want a daily-use cervical tVNS collar with four guided programmes and no clinical commitment, Pulsetto is the right shape. The lowest price, the broadest protocol library, and the no-cap session lifetime are the differentiators. Most consumer users land here.

Common questions

Which cervical tVNS device is best — gammaCore, Truvaga or Pulsetto?

Depends on what you want. gammaCore for clinically-indicated headache treatment with prescriber support. Truvaga for the gammaCore platform without the prescription gate. Pulsetto for the most accessible consumer cervical tVNS at the lowest price with the broadest protocol library.

Are Truvaga and gammaCore really the same hardware?

Same platform — both made by electroCore, both using the 5 kHz cervical burst waveform. The clinical labelling differs: gammaCore is FDA-cleared for migraine (prevention and acute treatment, age 12+), cluster headache, paroxysmal hemicrania and hemicrania continua, Truvaga is sold over-the-counter as a wellness device.

Is Pulsetto FDA-cleared?

No. Pulsetto is CE-marked in Europe as a consumer wellness device and sold OTC in the US. The only FDA-cleared non-invasive cervical VNS device is gammaCore, which is prescription-only.

Which has the strongest acute effect?

No study compares the three head to head — all target the cervical vagal trunk. gammaCore and Truvaga deliver focused 2-minute high-intensity sessions; Pulsetto delivers longer, gentler 4–20 minute sessions. Different temporal shapes; no published data compare their total dose or acute effect.

Can Truvaga replace gammaCore for migraines?

Not clinically — Truvaga is not FDA-cleared for any indication. Users with a clinical migraine or cluster diagnosis should use gammaCore under medical guidance. Truvaga is sold as a general wellness device, not a headache treatment.
