Why generic vitamins fail you.

Three reasons your CVS multivitamin is a placebo with extra steps.

The Biological Flaw

Taking energy and sleep vitamins together ruins absorption. Calcium blocks iron. Magnesium dampens B-vitamins.

The Wasted Money

Multivitamins cram 30+ ingredients you don't need at sub-clinical doses. You're paying for filler.

The Blind Guessing

No clinical validation. No data-driven dosing. No way to know if it's actually working for your body.

The Process

One protocol. Built only for you.

From AI quiz to a dietitian-validated daily ritual — designed around your biology, not a generic label.
