Most caffeine guidelines are a "flat 400mg," but pharmacologically, that makes no sense. A 100kg engineer and a 50kg engineer shouldn't have the same safety ceiling.
I built this tool to move beyond the "one-size-fits-all" FDA recommendation. It calculates your personalized limit using a weight-based pharmacokinetic safe-dose formula (standard 3-6 mg/kg) while factoring in physiological states like age and pregnancy that alter metabolic clearance rates.
Technical Logic: > - Uses a weight-based scalar for personalized limits.
Implements strict conditional logic for pregnancy/adolescent safety thresholds (capping at 200mg/100mg respectively).
Aiming to bridge the gap between "standard wellness" and actual biological data-points.

Interesting. I could benefit from this, although it would be nice to have the option to use pounds instead of kg.
Great point. I stuck with kg for the initial build since the pharmacokinetic formulas in the medical literature are almost universally SI-based, but I definitely see the friction for US-based users.
I’ll add a lbs/kg toggle to the roadmap and push an update later today. Thanks for the feedback!
