The founding deal
Free vitamins, for science.
We're building mosif with a small founding group. You get your first AM box and PM box free, 28 days of each. We get your honest data: how you slept, how you felt, what you actually took.
You get
- Your first AM + PM box, free
- A dietitian you can text
- A say in what mosif becomes
You give
- A tap on the box each day
- A quick check-in on day 17
- Your metrics, if you want to share them (wearables, bloodwork, all optional)
Here's what happens.
- 1
Meet Leah.
A Zoom call with your dietitian. Bring your goals, your questions and an honest picture of your routine.
- 2
Open your cabinet.
Show us everything you take today. We'll go through it together: what's working, what's doubling up, and what you can let go of.
- 3
We design your boxes.
A protocol built for you, on your schedule, reviewed by Dr. Zelensky. Often fewer pills than you take now.
- 4
Your boxes arrive.
AM for the kitchen, PM for the bathroom. 28 dated sachets in each.
- 5
We stay with you.
Daily taps, a day-17 check-in, and a real person to text whenever you need one.
the one rule
The cabinet swap.
Gather every vitamin and supplement you take right now. Put them all in a box. Put that box away, out of the kitchen and out of the bathroom. In their place: your mosif AM and PM boxes. Less stuff, often fewer pills, on a schedule made just for you.
Prescriptions stay exactly where they are. This swap is for vitamins and supplements only, and Leah will tell you if anything else should stay.
What's it worth?
We'll let you decide. It's a few hours of a registered dietitian, a physician and a caring friend, building a protocol that's right for you. For founding members, it's on us.
After your first 28 days
Show up, tap your box, share your data, and you'll be invited to keep going with a follow-on subscription, for science.
Your data is scrubbed and never tied to your name. It only helps us design better products.
Your data helps the next person figure out what works. Health, figured out together.

Founder · Customer #1
Shimon's schooling ended in elementary school; his education never did. Self-taught in behavioral psychology and metabolic biology, he spent decades building large-scale operations, then turned that rigor toward longevity, hand-building supplement protocols and accountability systems for the people closest to him. mosif.health turns that architecture into your daily habit.
"Your biology is an operating system. We provide the architecture. You become the operator."
