All infants should receive a daily vitamin D supplement of 8.5-10 mcg from birth until one year old, unless they are consuming more than 500 mL of formula milk a day, as infant formula is fortified with vitamin D.
Children aged between one and four years should receive a daily vitamin D supplement of 10 mcg. Parents should consider giving the same dose to children over four years, particularly through the winter months.

- advice on supplementation
- how vitamin D status should be assessed and who should be tested
