* The tolerable upper limit for vitamin C for infants aged 0-12 months has not yet been determined due to a lack of data about the adverse effects in this age group and a concern about the lack of ability of the body of infants to handle excess amounts. The only source of vitamin C intake should be from food (breast milk and/or baby formula) to prevent high levels of intake and possible adverse effects.
