Put vitamin D in your patients' hands without stocking a thing.

Roughly 70% of Americans are running low on vitamin D, and only about 3% of US healthcare spending goes toward prevention. D3X is a single liquid formula built around that one gap. Nothing else.

The practitioner program is free, takes about five minutes to set up, and your office never touches inventory, ordering, or fulfillment.


How it works

  1. We send you a bottle

    Free, no commitment. Read the label, try it yourself, and decide whether it belongs in front of your patients before you recommend anything.

  2. You get a code, a link, and printed cards

    Your patients get 20% off their first order. We mail you a stack of cards with your code on them, so a patient can walk out of an appointment holding it.

  3. They order direct, you get paid monthly

    Bottles ship to the patient's door on a subscription they control. You earn 15% of every order they place, including every refill, for as long as they stay on it.


Before you recommend it

The formulation, the sourcing, the testing, and the research it rests on are all on the site. Read whichever matters to you.


Request your bottle and cards

Free, no commitment, and we set up your code the same day so you are ready before it arrives.

We review each request by hand. If it is a fit, you will get your code, your link, and a tracking login within one business day. We do not share practitioner information with anyone.
