Blueberry and green tea extract combo shows antiviral potential
A new study found that a combination of blueberry and green tea extracts might prevent illnesses associated with prolonged and intensive exercise, especially the upper respiratory tract infection. Experts looked into long-distance runners and how their blood coped with viral infections, a common risk following hard training. The study found that test subjects who were given a pill containing blueberry and green tea extracts had higher levels of gut-derived polyphenols in their blood, thereby reducing the risk of virus infections following rigorous exercise. The dose used in the study contained the equivalent of 3 cups of blueberries and 1.5 cups of green tea extracts per day.
