Tech founder turned health innovator Kirk Ouimet of Phi explains how his team is translating decades of pharma-grade delivery tech into supplements that actually absorb, and pairing it with an AI health assistant designed to keep your data private while spotting issues earlier.
We dig into magnesium timing, iron + vitamin C synergy, menstrual-cycle-aware dosing, and how subjective check-ins plus wearables can guide smarter tweaks over time.
If you want supplements that respect your biology and your budget, this conversation lays out a clear, science-backed path forward.
