Clinical Trial Summary

Micellar encapsulation will be tested to increase the oral bioavailability in humans of 6-prenylnaringenin (6-PN) from hops (Humulus lupulus). The study follows a single dose (250 mg 6-PN), placebo controlled, randomized, double-blind, three armed crossover study design with ≥2-week washout periods. Plasma, urine and PBMC samples will be collected at intervals up to 24 h after intake of the native compound, the micellar formulation or placebo. The safety, pharmacokinetics and impact of oral prenylflavonoids on PBMC survival will be investigated.
