Calcium is vital for the development of the baby's bones and teeth. Pregnant women should aim for about 1,000 mg of calcium per day, increasing to 1,300 mg if under 19 years old. If dietary intake is insufficient from sources like dairy products, leafy greens, and fortified foods, calcium supplements may be necessary. Adequate calcium intake helps prevent maternal bone loss and supports fetal skeletal development. It's essential to take calcium supplements as directed, preferably in divided doses for better absorption. Consulting with a healthcare provider can help determine the need for supplements and appropriate dosages.
