About
We built the nutrition platform we wished existed.
Cellfie is a small team of dietitians, doctors, behavioral scientists and product designers. We were tired of nutrition being either watered-down or weaponized.

Our principles
Measure first, prescribe second. Every protocol begins with data — labs, history, lifestyle, taste. We refuse to template.
Coach, don't lecture. Our coaches are dietitians who learned how to listen. They reply in hours, not weeks.
Design like adults. Streaks and quests work because they respect your time. We build software you'd actually open.
Honesty over hype. If a protocol isn't right for you, we'll say so. If a supplement doesn't have evidence, we won't sell it.
