Dose & timing

Why it’s in the stack

Activates AMPK, inhibits mTORC1 indirectly, improves insulin sensitivity. The TAME trial (Targeting Aging with Metformin) is the marquee longevity rationale; Bryan uses extended-release to flatten the GI side-effects.

Lower second dose. Splitting 1.5 g/day across AM + PM smooths the lactate curve and improves GI tolerance vs. one bolus. Same TAME-trial longevity rationale as the morning dose.
