We know cold and flu season just ended, but it’s never too late to start thinking about how to protect yourself next year. Fortunately, researchers at the University of Florida may have found one of the best defenses yet. The study, which involved 120 healthy subjects with an average age of 26, found that supplementing with 2.5 grams of aged-garlic extract for 90 days or more may help reduce the symptoms of colds or flu by 21 percent and reduce the number of sick days in the workplace by 58 percent. (Mental note: Hide this magazine from the boss). Additionally, aged-garlic extract may help reduce the number of days one suffers from cold and flu symptoms by 61 percent. Researchers credit thiol, a sulfur compound, with causing the benefit.
