Dr. Neiman, a professor at Appalachian State University in Boone, NC has studied quercetin and its effects that are rumored to increase human performance. After testing quercetin on lab mice, the results showed an increase in their performance. After several studies with humans he discovered the quecertin did not increase any human performance alone. What he did discover that adding synergists to quercetin had a positive effect on his results. It is recommended to take quercetin in combination with green tea and/or fish oil.
