Recommended Mineral Intake

The following chart shows the recommended minimum daily intake and the recommended “not to exceed” daily maximums (tolerable upper intake levels) for minerals – as recommended for healthy adults by the Food and Nutrition Board of the National Academy’s Institute of Medicine, USA. When there is more than one line for a mineral, the first line is for everyone, ages 14 and older, unless a second or third line specifies an age group.

It’s not necessary for your multi-vitamin-mineral to contain 100% of every nutrient. Even then, however, the recommended daily intake for calcium would not fit into a single pill (or if it did, the pill would be huge).
