Why no height/weight input? Unlike per-kg supplements (creatine, protein), Fisetin has no published bodyweight-adjusted dosing in the research behind it. This calculator doesn't fabricate a per-kg formula that doesn't exist in the literature.

It’s worth being direct about something unusual here: unlike every other supplement on our network, published senolytic research on fisetin actually does use a bodyweight-scaled dose — roughly 20 mg per kg of body weight, taken for two consecutive days, then repeated after a month or more off. That protocol has been used across several registered clinical trials (sepsis, COVID-19, osteoarthritis, carpal tunnel syndrome), but as of this writing none of those trials has published peer-reviewed human efficacy results — only trial protocols and safety data exist so far. Because that protocol is a fundamentally different use pattern (pulsed, weight-based, unproven in humans) rather than a simple daily amount, we’re not building it into this calculator as if it were an established dosing standard. If you’re considering that kind of protocol, that’s a conversation to have with a doctor, not a calculator output.
