What is the recommended daily allowance (RDA) for calcium?

The recommended daily allowance (RDA) for calcium varies by age and gender, but for most adults, it is set at around 1000 mg per day, increasing to 1200 mg for women over 50 and men over 70. Calcium is essential for maintaining strong bones and teeth, as well as supporting muscle function, nerve transmission, and vascular contraction. The higher recommendation of 1200 mg for older adults takes into account the decreased absorption and increased need for bone health as one ages, which helps prevent osteoporosis and fractures.

Therefore, for adults, while the general guideline is often 1000 mg, the recommendation of 1200 mg is aimed at specific populations that are more at risk of calcium deficiency and related health issues. This highlights the importance of tailoring nutritional recommendations based on demographic and health factors.
