Built for your body, not the average one.

Thirteen short questions on goals, life stage, sleep, stress, diet and symptoms. We build the daily pack of individual pills that actually fits you — not a generic multi dosed for nobody.

Our standard

We say no a lot. That's the whole product.

Studied form, studied dose, or it's out.

If the human RCT used 400 mg of magnesium glycinate, we use 400 mg of magnesium glycinate — not 50 mg of oxide because it's cheap. Then we tune that dose to your assessment.

Individual pills. Not one big blend.

Your pack is the specific pills your assessment surfaced — packed into a daily sachet. We don't blend everything into one capsule, because that forces compromises on dose and form.

No proprietary blends. Ever.

"Proprietary blend" means "we won't tell you the dose." If we put it in your pack, we tell you exactly how much. If we can't justify the dose, we don't put it in.

How is this actually personalised?

−

Your 2-minute, 13-question assessment drives a daily pack of up to 6 individually selected pills — built around your sleep, stress, diet, life stage and goals. No two Capsi packs are identical, and your formula evolves as you re-take the assessment each season.

Is this one pill or several?

Several — and that's the point. We send you the specific pills you need, packed into a single daily sachet. We don't blend everything into one capsule, because that would force compromises on dose and form. Each pill is dosed independently, so we can dial each one to you.

Is this a subscription?

Your first order ships once. After that, you choose: every 30, 45, or 60 days. Skip, swap, or cancel from your dashboard. No phone trees.

Where do you source ingredients?

Every batch is third-party tested by Eurofins. We publish the full Certificate of Analysis on each product page. Sourcing notes live next to every ingredient.

How is Capsi different from a pharmacy multi?

Most pharmacy multis use floor doses and the cheapest forms (oxide magnesium, cyanocobalamin), all crammed into one tablet. We use studied forms at studied doses, kept as separate pills, then dialled to you. It costs more. It also works.

Vegan? Gluten-free?

All Capsi capsules are vegan and gluten-free. Daily Foundation and Skin & Hair are also soy-free. See the allergen panel on each product.

Can I take this with medication?

Always bring your stack to your doctor before starting any supplement. We'll send a labeled regimen card you can hand them.
