IMMUNE SYSTEM SUPPORT.
A randomized, double-blind, placebo-controlled clinical study of forty test subjects. Subjects were subjected to extreme physical stress during a five-week period. Half were given 1,000 mg of quercetin daily and half were given a placebo. While markers of immunity did not differ significantly between the quercetin and placebo groups, in the quercetin group, the incidence of upper respiratory tract infection was significantly reduced.
40% fewer athletes in the quercetin group experienced upper respiratory tract infection
* 9 of 20 placebo group athletes experienced infection. 1 of 20 quercetin group athletes experienced infection.
