Best vagus nerve stimulator
For a best vagus nerve stimulator recommendation, Pulsetto leads our tests for comfort and ease of daily use — though free techniques in our Vagus Nerve Hub work well for most people without any device at all.
Nervous system supplements worth considering
Among nervous system supplements, magnesium glycinate has the strongest evidence base for calm and sleep support — read magnesium glycinate benefits for the full research breakdown. Ashwagandha is another well-studied option: several trials support ashwagandha benefits for lowering perceived stress and cortisol.
Magnesium for anxiety
Magnesium for anxiety support works best in glycinate form, which is gentler on digestion than magnesium oxide or citrate. It’s not a fast-acting sedative — expect gradual support over 2–4 weeks of consistent use, not instant results.
