Calcium

Calcium is crucial for preconception, pregnancy, and postpartum due to its fundamental role in supporting foetal development, maintaining maternal bone health, and facilitating various physiological processes. 

Calcium and Pregnancy

Adequate calcium levels are essential for the formation of the foetal skeleton and teeth. It also contributes to proper cellular functioning, supporting the intricate processes involved early embryonic development.

Calcium is also critical for the development of the baby's heart, and nervous system. The baby draws on maternal calcium stores for its growth, which emphasises the need for sufficient calcium intake to prevent maternal bone depletion. Calcium also plays a role in blood clotting, muscle function, and nerve transmission, which are vital for both the mother and the developing baby.

Calcium and Postpartum

Postpartum, calcium continues to be essential for maternal bone health, especially if there was a depletion during pregnancy. Adequate calcium intake supports postnatal recovery and contributes to overall well-being.
