How we run the store

These are the rules we run Cellovi by. Each one is a promise we keep, and each links to the full terms. Last updated: October 28, 2026.

Orders and delivery

We prepare and ship your order within 2 to 5 business days, Monday to Friday, excluding US holidays.
Delivery by USPS then takes 1 to 4 business days, so most orders arrive within 3 to 9 business days of ordering. These are estimates, not guarantees.
You get a tracking link by email the day your order ships.
If your parcel is lost in transit, we send you a free replacement.

A person reads every message. We reply within 24 to 48 hours, Monday to Friday.
Orders, refunds and subscriptions: support@cellovi.com. Everything else: hello@cellovi.com. To report a reaction to a product: safety@cellovi.com.

Your first order with Cellovi comes with our 60-day first-order guarantee.
If anything arrives damaged, defective or wrong, write to us within 21 days and we replace it or refund it, shipping included.

Only NMN, NAD+, Probiotic 40 Billion and Colostrum Powder come as a subscription. Everything else is a one-time purchase, with nothing to cancel.
We email you before every renewal.
Skip, pause, change the date or cancel online from your account, any time before your renewal date. No minimum term, no fee and no phone call.
A renewal that has been charged but not yet shipped is cancelled and refunded if you email us.
If a subscription price changes, we tell you at least 7 days before it applies.

Every ingredient and every amount is on the label and on the product page, as text you can read and search.
Every claim carries an evidence grade, Established, Growing or Frontier, with the key studies linked on the product page.
If a formula, a dose or a count changes, we update the product page and note the change with its date.
