A plain, unformulated fisetin at 250 mg per capsule with nothing else in the bottle, which makes it the simplest option to dose against a specific research protocol. Two capsules reach the 500 mg figure most daily-use discussions settle on, and the pulse protocols scale up from there.
Uses the fenugreek galactomannan delivery approach that appears in the only published human pharmacokinetic study of fisetin, where an encapsulated form reached a peak plasma concentration more than twenty times higher than plain powder. If poor absorption is your main objection to fisetin, this is the format with human PK data behind the concept.
Pairs fisetin with quercetin, the combination most senolytic stacking discussions arrive at, in a liposomal format. Note that the 1200 mg on the label covers the full blend rather than fisetin alone, so read the supplement facts panel before assuming that is your fisetin dose.
States a 98 percent or higher purity spec on a 500 mg capsule, which matters because fisetin extract purity varies widely between suppliers and the label percentage determines how much fisetin you actually swallow. Single-capsule 500 mg dosing also means fewer pills on the higher-dose protocols.
Sold on an enhanced-absorption claim rather than on raw milligrams, which is arguably the more relevant axis for a compound with fisetin’s oral bioavailability problem. Absorption multiples printed on supplement labels are manufacturer figures rather than independent ones, so read the number as a formulation signal rather than a measured result.
A liposomal 500 mg option for anyone who wants the higher per-capsule dose and a lipid delivery format in the same product. Liposomal encapsulation is the most common commercial answer to fisetin’s solubility problem, though head-to-head human comparisons against plain powder remain scarce.
