Vin picks. A partner ships.
Personalized supplement packs, delivered monthly. Vin picks each supplement against your real data — low ferritin, high homocysteine, protein-heavy diet, sub-optimal magnesium — and a trusted partner ships the pack pre-portioned by day. No shopping, no guessing, no forty bottles on the counter.

The current supplement experience
Everyone's guessing.
- A quiz on a website picks your stack based on age + a checkbox.
- Or a Reddit thread, or an influencer's Amazon list.
- Or you read a book, buy forty bottles, and end up taking three.
- Nobody knows if it's actually doing anything.
With Shantivita stacks
Picked from your data.
- Vin picks each supplement against your labs, meals, sleep.
- Pre-portioned monthly packs — one packet per day.
- Reformulated as your data changes — new labs, new pack.
- Interaction warnings from Vin before anything gets added.
- Fulfilled by a supplement partner known for third-party testing.
How the pack gets picked
Four signals in, one pack out.
Vin reads your existing data every month before the next pack ships. The pack changes when the data changes.
Labs
What's actually low.
Ferritin under 40? Iron. Vitamin D under 30? D3. Homocysteine elevated? B-complex. Objective, not aspirational.
Meals
What your food isn't giving you.
Low omega-3 intake this month? Fish oil. Vegetarian and light on B12? Methylcobalamin. Data-driven, not one-size.
Sleep + stress
What your patterns say.
Rough sleep + elevated HRV drops? Magnesium glycinate or L-theanine. Only when the data supports it.
Your goals
What you're actually working on.
Post-menopause? Bone-support stack. Endurance athlete? Recovery-forward. The pack knows what you're solving for.
