Do you need gel with a vagus nerve stimulator?
Not with Vagal Buddy or Vagal Oh!. Gel or paste is optional and only changes comfort. A tube comes in the box and softens the tingle under the clip. A drop of water gives more sensation, and if your skin is naturally moist you may use nothing at all once you are used to the feeling.
Three ways to use it
Gel or paste
A small dab on the contacts spreads the sensation, so the tingle under the clip feels gentler. Good for your first sessions or if your skin is sensitive. A tube is in the box with Buddy and Oh!.
A drop of water
Water gives a clearer, more local tingle than gel. Some people prefer it because they like to feel the stimulation working.
Nothing at all
If your skin is naturally moist, you can use nothing at all once you are used to the sensation.
Why it changes the feel, not the dose
Buddy and Oh! are current-controlled. They measure the contact with your skin continuously and hold the current you set, so gel, water or nothing changes how the stimulation feels, not how much current reaches the tragus. On a voltage-controlled device the delivered current moves with skin moisture, so what you put on the skin can change the dose as well as the feel. Voltage vs current control, explained.
