Infants and children need good sources of calcium in their diets on a daily basis. Calcium absorption in the gut is variable and ranges from 25-50%, increasing when intake is low and reducing when intake is high. Plenty of foods rich in calcium are especially important throughout infancy to support the rapid bone growth and bone mineralisation that occurs at this time. The uptake of calcium by bones is then regulated by Vitamin D, with Vitamin D deficiency limiting bone mineralisation even in the presence of adequate calcium.  Growth spurts during infancy and childhood, from a surge in growth hormone provides a boost to calcium absorption, which further strengthens bone mineralisation. Absorption of calcium from breast milk is very efficient at around 66% and from formula milk around 40%.   For all infants and young children offer them calcium rich foods every day.

  • Dairy products like milk, cheese and yoghurt are the UK’s best sources of calcium for infants and young children

  • Water in areas of hard water like Cambridge contains 120mg calcium per litre
  • For all children with cow’s milk allergy, take care to offer calcium enriched products, checking sources of other valuable nutrients such as protein, iodine, Vitamin D as well as overall calories
  • Prolonged poor calcium intake will lead to brittle bones that break more easily, both in childhood and in later adulthood
  • Exercise and weight bearing activity will also strengthen bone
  • Have a quick check on recommended intakes to check if your child is getting enough calcium
  • Download the portions of calcium rich foods below
  • Infants and young children need a Vitamin D supplement containing a minimum of 10ug daily until 5 years and thereafter for a minimum of the 6 Winter/Spring months to maintain good levels

Recommended Intakes
