    six months

Study Arms (2)

Quercetin

ACTIVE COMPARATOR

Quercetin 2000 mg/day Quercetin is provided as orange flavored soft chews and each chew will have 250 mg of quercetin Quercetin will be administered orally twice daily, one half dose (4 chews) in the morning after breakfast and one half dose (4 chews) in the evening after dinner for six months.

Drug: Quercetin

Placebo

PLACEBO COMPARATOR

Placebo is also provided as soft chews that is similar to quercetin in color, taste and texture and will contain all the stabilizers and the inactive ingredients that is present in the quercetin chews. Placebo will be administered orally twice daily, one half dose (4 chews) in the morning after breakfast and one half dose (4 chews) in the evening after dinner for six months.

Drug: Quercetin
