The needs amount to 2.4mg per day with an increase in case of high energy expenditures in athletes. Needs are sufficiently covered by foods and deficiencies are exceptional. Moreover, the hepatic reserve avoids any risk of deficiency, except in case of important dietary imbalance or in vegans since it is only supplied by products of animal origin. Vegetarians can avoid vitamin B12 deficiency by eating eggs.
