Does ZenoWell Have Side Effects?

Based on the latest meta-analysis involving data from nearly 500 healthy participants, taVNS has been shown to be generally safe. Only a small proportion of users (less than 5%) experienced mild and short-lived side effects, such as headaches, dizziness, or skin irritation — all of which typically resolved after discontinuing stimulation. Importantly, no known long-term risks have been identified.
