At the first sign of trouble, just mix one with hot water for a throat-calming treat. The citrus-flavored formula contains echinacea and zinc, both proven immune supporters, while elderberry provides an added antioxidant boost, and elm bark soothes sore throats. An easy way to support your health during the holidays, these are also terrific for protecting yourself from airplane colds or the after-effects of late nights. About $6 for a six-pack box; many online drugstores offer a healthy discount. Check out Nutrition Now’s whole line of natural cold support and other herbal supplements at www.nutritionnow.com.
