Patient One ViraCare™ supplies a synergistic botanical blend to stimulate immune system response. Combined with a foundation of standardized andrographis are standardized extracts of echinacea, astragalus and elderberry that supply additional immune-supportive polysaccharides, flavonoids and alkaloids. The immune boosting agents in ViraCare are recommended for rapid natural support when the body is challenged by stress and seasonal respiratory issues. Key Ingredients Andrographis and elderberry are associated with reducing discomfort from acute respiratory complaints when taken at the onset of distress. Echinacea and astragalus provide antioxidant defense and contribute adaptogenic actions in helping to protect against and resist the effects of occasional stress, including defense for upper respiratory challenges. Our formula includes Echinacea purpurea paired with Echinacea angustifolia extracts for complementary effects from the variation in presence and concentration of their key active compounds.
