FAQ

What is "daily function"?

It's our name for the everyday things that shape how a day feels — energy, mental clarity, mood, digestion, and joint mobility. We build formulas around these instead of around clinical symptom language.

How does Build Your Function work?

Pick two or more pillar formulas and get a tiered discount automatically — 10% off for two, 20% off for three or more. Mix and match based on what your days actually need.

How does the subscription work?

Subscriptions include 20% off and free shipping, with delivery every 30, 45, 60, or 90 days. Change your cadence or pause anytime from your account.

Is there a loyalty program?

The Periodica Circle is launching after our founding season — you'll be able to earn points toward future formulas with every order.

Are these formulas third-party tested?

Formulation and testing details will be published here as manufacturing is finalized.
