Ingredients According to the official website, Airborne contains zinc, ginger, Echinacea and up to 13 other vitamins, minerals and herbs. Each Airborne product has a different formulation and ingredient list. The ingredients in most Airborne products include: Vitamin A as retinyl palmitate Vitamin C (ascorbic acid) Vitamin E (as delta-tocopheryl acetate) Riboflavin (vitamin B2) Magnesium (as oxide and sulfate) Zinc (as sulfate) Selenium (as amino acid chelate) Manganese (as gluconate) Sodium Potassium Yeast Herbal extract blend containing: Lonicera (flower), Forsythia (fruit), Schizonepeta (aboveground parts), ginger (dried rhizome), Chinese Vitex (fruit), Isatis (root) and Echinacea (aboveground parts) Amino acids: glutamine (as L-glutamine) and lysine (as L-lysine HCl) Other ingredients: maltodextrin, sorbitol, citric acid, sodium bicarbonate, potassium bicarbonate, orange flavor, mineral oil, acesulfame potassium, and sucralose Side effects The official website does not list any side effects that one might experience after taking Airborne, aside from "some sensitivity to any of the vitamins or herbal extracts", but people who might be allergic to one of the ingredients of the product are advised to avoid using it or to consult a doctor. Also, people who are taking another type of medication at the same time or who suffer different medical conditions should consult a physician before taking Airborne. Side effects from vitamin overdoses may occur, especially in patients with kidney failure. In very large doses, vitamin C in kidney-failure patients can cause severe side effects such as oxalate deposits in bone and soft tissues and may interfere with the absorption and metabolism of vitamin B12. The product contains 1 g of vitamin C per serving and a recommendation to take up to three servings per day. However, the Institute of Medicine states in the Dietary Reference Intakes that vitamin C consumption should not exceed 2 g/day.
