What the brand says

High potency vitamin C with bioflavonoids.Antioxidant vitamin C is required for at least 300 metabolic functions including tissue growth and repair, adrenal function and gum health.Bioflavonoids support vitamin C absorption. Taken together, both nutrients are more effective than either when taken alone. Since neither of these important nutrients can be produced by the human body, they must be supplied through the diet or in supplement form.
