NerveZen carries a 60-day money-back guarantee from the date of purchase.
The guarantee runs for 60 days from purchase and covers dissatisfaction with your results or your overall experience. Bottles can be returned even if empty, per the brand's stated policy, which comfortably covers the several weeks nutritional support of this kind typically needs to show an effect.
Contact the official store directly with your order number, within the 60-day window, by email or phone. Full terms are confirmed at checkout on the official order page.
