Introduction

Components:

ellagitannins, proanthocyanidins, anthocyanins, & other flavonoids in berrys are poorly absorbed & highly metabolized
parent compounds, metabolites & conjugates detectable in human tissue

12% improvement in memory over 2 year period in subjects age 50-84 consuming 1 cup of frozen blueberries/day; No study controls^[2]
lowers serum triglycerides (40%) & LDL cholesterol (20%)^[3]
100 grams of blueberries for 4 weeks, twice a day is associated with lower systolic blood pressure^[4]
