And sorry if this was asked before, in this thread (search engine doesn't seem to work) but what are your thoughts on the bio-fisetin or senolytic activator (the new one with added bio-fisetin) from Life Extension? I generally respect their cutting edge original supplements and they seem to know what they're doing but has anyone tried these? Other than some unpublished pre-clinical human data to show much higher biovailability (vs the plain high dose unformulated fisetin as in the mayo trials), there's nothing else to go on. Might be worth a try though based on a hunch or just continue with plain 'ol fisetin. The senolytic activator looks interesting. Any chance, at least in theory, that this formulated "bio-fisetin" would work well? LE from their site quote "But during digestion, much of fisetin is rapidly converted into other compounds by a process called conjugation. That’s why we protected fisetin by combining it with galactomannans, a type of fiber derived from fenugreek seed. Doing so makes it up to 25 times more readily available than standard fisetin."
Furthermore, I found this from another website:
"LE's Bio-Fisetin page references their Curcumin Elite page (which uses the same bio-boost trick), which in turn gives journal references. Chasing these references down two levels in the Journal of Functional Foods yields the following description of how they combined Curcumin with Fenugreek Powder to boost bioavailability:
'Various percentage CGM were prepared by ultrasound mediated gel-phase dispersion of curcuminoids in fibre matrix. Briefly, 1 g curcumin powder was uniformly suspended in 100 ml of water containing 0.1% weight of hydroxypropylmethyl cellulose and 10% (w/v) glycerine under sonication for 20 min, at 60 C. Soluble dietary fibre powder (2.5 g) was separately dissolved in 100 ml water with sonication to a homogeneous viscous solution. Curcumin solution was then slowly added to the fibre solution. Care was taken to keep the temperature below 50 C during ultrasound-mediated mixing. Cloudy yellow aqueous solution thus obtained was dried under vacuum at 60 C and the resulting yellow flakes were
milled and sifted to produce uniform microgranulates of 150 ± 20 lm in size. The procedure was repeated to produce CGM containing various percentages of curcumin, ca. 20, 40 and 60.' "
So, could this also work with their bio-fisetin?
