NOW® Air Defense® is a blend of ingredients that support healthy immune function and respiratory health during seasonal changes and year-round. Air Defense® contains PARACTIN®, a patented extract of Andrographis paniculata. Studies have shown that PARACTIN® helps to support a healthy and balanced immune response. ImmunEnhancer™, Elderberry, Echinacea, and Astragalus herbal extracts have also been included for their healthy immune supporting properties. Olive Leaf Extract has been added to help to maintain healthy respiratory function.*

7-KETO® is a naturally occurring metabolite of DHEA, providing the same benefits as DHEA without its associated side effects.  Because the body's production of DHEA declines with age, so does the production of 7-KETO.  Weight gain is a common sign of aging that often accompanies the decreased production of DHEA and its metabolites.  7-KETO® has been patented for its ability to safely promote thermogenesis as well as for the maintenance of healthy body weight.*

This NOW product has been improved to provide higher potencies and a more balanced spectrum of beneficial bacteria found in human intestinal tracts. Regular intake of beneficial probiotics can aid in maintaining healthy intestinal flora.*
