Scientific Opinion on the safety and efficacy of vitamin C (ascorbic acid and sodium calcium ascorbyl phosphate) as a feed additive for all animal species based on a dossier submitted by VITAC EEIG
EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP)
Vitamin C (formerly known as antiscorbutic vitamin) is essential for primates, guinea pigs and fish. Vitamin C, in the form of ascorbic acid and sodium calcium ascorbyl phosphate, is safe for all animal species. Setting a maximum content in feed and water for drinking is not considered necessary. Data on the vitamin C consumption of consumers are based on the levels of vitamin C in foodstuffs, including food of animal origin, produced in accordance with current EU legislation on the supplementation of feed with vitamin C. The exposure is far below the guidance level. Any potential contribution of the use of vitamin C in feed is therefore already considered in the above data. Consequently, the use of vitamin C in animal nutrition is not of concern for consumer safety. In the absence of inhalation toxicity studies it would be prudent to assume that inhalation of dust from the additives presents a health hazard to workers and measures should be taken to minimise inhalation exposure. In the absence of data, ascorbic acid and sodium calcium ascorbyl phosphate should be considered as irritant to skin and eyes and as dermal sensitisers. The supplementation of feed with vitamin C does not pose a risk to the environment. Ascorbic acid and sodium calcium ascorbyl phosphate are regarded as effective sources of vitamin C when added to feed or water for drinking.
