F06 / AI health chat

Twenty-eight specialised tools. One conversation.

The model can look up interactions, cross-reference biomarker trends, simulate protocol changes, and evaluate supplements — within a single conversation. Tool calls are visible inline; nothing is opaque.

am I taking the right form of folate?
⚙ genetics_lookup⚙ stack_inspect
No — switch folic acid → methylfolate (5-MTHF). You're MTHFR C677T heterozygous; ~40% conversion deficit. Recommended dose: 400–800 mcg/day. Pair with B12 methylcobalamin.
simulate adding NAC 600mg twice daily
⚙ simulate_protocol
Projected: GSH ↑ 18%, ALT ↓ 12%, no interaction conflicts. Compatible with your APOE3/4 cardiovascular protocol. Recommend morning + evening with food.
F09 / Composite bio age

Nine systems. One composite.

PhenoAge, GrimAge, DunedinPACE, and six more. Weighted composite for accuracy, with per-system attribution so you can see which intervention is moving which clock.

Per-system breakdown
Cardiovascular age, immune age, telomere length, epigenetic clock, more.

Year-over-year deltas. Stagnation flagged.

Variant Implication Status
MTHFR C677T heterozygous — switch folic acid to methylfolate (5-MTHF), 400–800 mcg/day. action
APOE 3/4 heterozygous — elevated CV risk; LDL target 70 mg/dL; consider statin. action
VDR BsmI bb — favourable response to vitamin D3; standard dose appropriate. ok
SOD2 rs4880 AG — moderately elevated oxidative stress; ubiquinol over ubiquinone. action
