Calcium and Vitamin D: What Does Recommended Dietary Allowance Mean?
by Cal-EZ Team
When people are taking supplements, there comes a time when they wonder if they’re taking enough or not enough of their supplement. In future blog posts, we’ll cover the symptoms of too little and too much calcium and vitamin D.
The US and Canadian governments asked the National Academy of Medicine (formerly the Institute of Medicine) to review and update the dietary intakes of nutrients. The National Academy of Medicine set the Recommended Dietary Allowance (RDA) of calcium, vitamin D, and other dietary supplements. Their recommendations are based on the needs of healthy individuals. These guidelines are widely used by the US and Canadian governments and many healthcare providers to determine how much calcium and vitamin D we need. Below is a table of RDAs for calcium and vitamin D. In the absence of any disease or condition, these RDAs for calcium and vitamin D should be sufficient. However, if you have certain medical conditions, you and your doctor may decide to increase the amount of calcium and/or vitamin D you take to keep you healthy. To learn more about calcium, see our previous posts about the four most common forms of calcium, taking calcium with other medications, and calcium and constipation.
