What is the Recommended Dietary Allowance (RDA) of calcium for adults?

The Recommended Dietary Allowance (RDA) for calcium in adults is set at 1000 mg per day for most adults, which is critical for maintaining bone health and supporting various physiological functions. Calcium plays an essential role in the development and maintenance of bone density, helping to prevent conditions such as osteoporosis.

This RDA is tailored to cover the needs of the majority of healthy individuals in a given age and gender group, ensuring adequate calcium intake to support these vital processes. For women over the age of 50 and men over the age of 70, the RDA increases to 1200 mg per day to account for increased needs as bone density naturally declines with age.

While other figures might represent different life stages or conditions, the specific requirement for adult men and women is indeed 1000 mg/day. Thus, this answer reflects the standard nutritional guideline and ensures that adults maintain optimal health related to calcium intake.
