Airborne can help prevent or shorten duration of colds.
Airborne is a dietary supplement used for prevention and treatment of colds and flu. It's the one that was "developed by a school teacher who was sick of catching colds in class." Airborne contains several vitamins, minerals and herbs. The manufacturer suggests taking one tablet every 3 hours at the first sign of a cold.
It is important to note that one tablet contains vitamin C 1,000 mg...vitamin A 5,000 IU...vitamin E 30 IU. These amounts meet or exceed the RDA.
Vitamin C taken prophylactically in doses of at least 1 gram per day seems to reduce the duration of cold symptoms by a half-day. Tell patients the slight reduction in duration of cold symptoms may not be worth large doses of vitamin C on a daily basis.
