"Nadovim can be purchased as a one-time purchase for $89/bottle, or as a monthly subscription for $80/bottle a month. Simply change the buying option on the purchase page while placing your order. With the monthly subscription, we will send you the number of bottles selected at checkout each month so you do not forget to reorder. The monthly subscription option will renew each month until canceled. Each bottle of Nadovim consists of a one-month supply, and the best results are achieved after at least 2-3 months of use. Many doctors recommend continuous use to replenish levels of NAD+ and other key metabolites and nutrients in the brain that are consistently being depleted (either due to aging or environmental factors). Subscriptions can be managed through the account page after purchase, where you can easily cancel the subscription, change the payment method, or change the shipping address. There is no cancellation fee, and you may cancel at any time. If you wish to quicken, delay, pause or indefinitely suspend your delivery, please contact us at firstname.lastname@example.org and we'd be happy to help."
