Doctor at Appalachian State University did a study on endurance athletes and found remarkable benefits to the nutritional supplement quercetin. Giving 40male cyclists either a placebo or 1 gram of quercetin daily, they found that the ones given the placebo had nine chest infections after two weeks of rigorous training and the quercitin group only had 1. This is a major improvement and should be studied in bigger groups.

In lab studies, quercetin, a flavonoid found in fruits, berries and tea, bound itself to bacteria and viruses, stopping them from duplicating. This may be why quercetin supplementation may be beneficial this winter when you’re trying to avoid catching a cold. I would suggest combining it with about 1,200 IUs of vitamin D and 1,000 mgs of vitamin C each day. I know I will.
