Antenatal clinics - Vitamin supplements
During pregnancy, the nutritional requirement increases. In most instances, there may be no need for supplementation. It is recommended that in the first three months of pregnancy folic acid is taken to reduce the risk of the baby having abnormalities of the brain and spinal cord. This is best started way before the pregnancy occurs.
Iron supplementation is usually advised if your blood level is low or you are carrying twins.
For those women who are overweight, it is desirable to take vitamin D supplements during pregnancy. This has tremendous benefits for the pregnancy. Taking calcium supplements and other substances like omega 3 does not seem to confer much benefit. It is therefore not recommended.
