Step-by-step explanation:
The recommended daily calcium intake for women over 19 according to health guidelines is 800 mg per day. Calcium is essential for building and maintaining strong bones, and it's particularly important during adolescence and early adulthood. Good sources of calcium include dairy products like milk, cheese, and yogurt, as well as green, leafy vegetables. It's also beneficial to have a diet rich in vitamin D, as it promotes calcium absorption. For pregnant women in their second and third trimester, and during lactation, the requirement increases to 1.2 grams per day.
