01 / The problem

You've been told your labs are “normal” for years. But you still don't feel right.

02 / The barrier

A full functional medicine workup used to mean long waitlists and out-of-pocket costs most people couldn't afford.

03 / The unlock

SFAI changed that. Your doctor now runs 166+ advanced tests, analyzes them with AI, and delivers your personalized 12-week plan in a fraction of the time and cost.

01 / The problem

"Your labs are normal."

You feel exhausted. Foggy. Bloated. Your weight won't budge. You can't sleep through the night. But every test comes back "within range," and you leave with nothing.

Standard lab ranges are built on averages, including sick people. They catch disease, not dysfunction. Functional medicine uses optimal ranges built on what healthy bodies actually look like. The difference is everything.

Normal vs. Optimal

Your doctor said everything looks "normal" — but is it?

02 / The approach

Your doctor,
with superpowers.

SFAI gives your doctor tools that used to take a functional medicine specialist hours of manual work: comprehensive lab extraction, functional-range analysis across 166+ tests, and personalized 12-week protocol drafts built from your specific results.

Your doctor reviews every finding, adjusts what needs adjusting, and approves your plan before it ever reaches you. The AI does the heavy lifting. The doctor still makes the call.

You get a level of detail that used to be reserved for expensive specialty practices, delivered in minutes instead of hours, at a fraction of the cost.
