Effects of the flavonoids quercetin and apigenin on hemostasis in healthy volunteers: results from an in vitro and a dietary supplement study

K Janssen et al. · The American journal of clinical nutrition · 1998 · 67(2):255-62

Randomized dietary crossover study with supporting platelet experiments. Neither food intervention changed measured hemostatic outcomes, although high concentrations inhibited platelets in vitro. Direct human intervention or pharmacokinetic evidence. This is an individual study, not replicated highest-tier clinical proof; sample size, controls and the measured endpoint limit its interpretation.
