Because your body can’t make calcium, the only source is through your diet. An adequate intake stops your body withdrawing calcium from your own stores, which could affect your own bone health. So as well as helping your baby grow and develop normally, a healthy calcium intake in pregnancy is important for your own bone health too2.
Even though your baby requires plenty of calcium, the daily recommended amount for women during pregnancy is the same as it would usually be – 700mg per day1. What can be different is that your body cleverly adapts to help serve your growing baby’s needs, absorbing more of the calcium you eat, and making more available to meet the increased demands2.
Once your baby is born, breast milk takes on the job of providing all the calcium your baby needs. If you decide to breastfeed your baby, you shouldn’t need to make any special dietary changes but it’s a good idea to eat healthily. You can always talk to your midwife or healthcare professional if you’d like more advice.
Because of our moderate dairy intake, most people in the UK get enough calcium without making a special effort. If you’re vegan or follow a plant-based diet, or unable to eat dairy foods for another reason, you may need to top up your daily intake with a calcium supplement during your pregnancy. It’s important to talk to your midwife or other healthcare professional before talking any supplements during pregnancy.
