Vitamin C with Flavonoids is a popular combination of ascorbic acid and citrus flavonoids. Vitamin C contributes to a number of functions within the body including normal function of the immune system, support against oxidative stress, increases iron absorption and aids the reduction of fatigue.
Additional Warnings: Vitamin C can cause diarrhoea in some individuals in large doses, which can vary from person to person. This resolves when the dosage is reduced.
