Chrysin
Chrysin is a flavonoid, a type of plant polyphenol, found in honey, propolis and passionflower.
Also listed as Propolis, Honey extract, <em>Passiflora caerulea Linn</em>
Why does absorption matter?
In seven healthy volunteers given 400 mg, very little unchanged chrysin reached the blood. This single-dose experiment helps explain why laboratory concentrations may not be achievable with conventional oral products; it is not a dosing recommendation. 1
What about newer formulations?
A 2025 crossover study in 16 healthy adults found more chrysin reaching the blood with a micellar chrysin-quercetin-rutin blend. Better absorption does not itself show a hormone benefit. Commercial ties and a pending formulation patent were disclosed. 2
