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. 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-vitaminmineral 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).
NK = means “not known”
Mg = milligrams
Mcg = micrograms (1,000 mcg = 1 mg)
