Onion extracts may boost uptake of berry polyphenols
A new study from Canada says onion extracts may boost uptake of berry polyphenols. Polyphenols are abundant micronutrients in our diet and berries have a high concentration of them. Researchers from the Institute of Nutrition and Functional Foods (INAF) at Laval University highlighted a possible synergistic activity of phenolic compounds for improving bioavailability. This work allowed the characterization of actual phenolic metabolites generated in vivo following a phenolic intake. Blood levels of the three select polyphenolic compounds from Nutra Canada’s GlucoPhenol blend of strawberry and cranberry were increased by between 118% and 252% when consumed in combination with the onion extract.
