Current Research

I am currently researching the effects of urolithin isoforms (metabolites of polyphenols) in metabolic models of oxidative stress. Ellagitannins and ellagic acid are polyphenolic compounds derived from various plants. Fruits and nuts that are rich in ellagitannins include: pomegranates, blackberries, raspberries, strawberries, muscadine grapes, and walnuts. However, these polyphenols exhibit low bioavailability following metabolism. Upon entering the gut, colonic microbiota catabolize these ellagitannins to a metabolite called urolithin, which has high bioavailability and can be better absorbed. Both in-vivo and in-vitro studies have shown that consumption of ellagitannin-rich sources have yielded protective health benefits in metabolic, inflammatory, cardiovascular, and neurological disorders, but more research is needed to elucidate the bio-protective effects associated with these compounds.
