Questions about manganese
What is the FDA Daily Value for manganese?
The FDA Daily Value for manganese is 2.3 mg for adults and children 4 years and older. On a Nutrition Facts label, a serving's %DV for manganese is its amount divided by 2.3 mg, times 100.
How do I work out the %DV for manganese?
Divide the amount in one serving by 2.3 mg and multiply by 100. Then round to the nearest 2% up to 10%, to the nearest 5% above 10% and up to 50%, and to the nearest 10% above 50%. For example, 0.46 mg ÷ 2.3 mg × 100 = 20%.
How are vitamin and mineral %DV values rounded?
The percentages for vitamins and minerals shall be expressed to the nearest 2-percent increment up to and including the 10-percent level, the nearest 5-percent increment above 10 percent and up to and including the 50-percent level, and the nearest 10-percent increment above the 50-percent level.
Manganese rounding rules
Amount
Manganese is declared to the nearest 0.01mg. Measuring finer than that changes nothing on the label.
| Amount range | Rounding rule |
|---|---|
| ≥0 | nearest 0.01 mg |
These mg increments come from FDA guidance, banded by this group's Daily Value.
% Daily Value
| %DV range | Rounding rule |
|---|---|
| 0 to 10% DV | Nearest 2% |
| >10 to 50% DV | Nearest 5% |
| >50% DV | Nearest 10% |
Every %DV a label can show
What a serving has to contain for a label to print each figure. The %DV is worked out from the actual amount, before that amount is rounded.

The rules are FDA's; the inversion is ours. Ranges are inclusive at the low end and exclusive at the high end, because an exact half rounds up.
Does the manganese Daily Value change for children or pregnancy?
Yes. It is 1.2 mg for children 1 to 3 years, is 2.6 mg during pregnancy and lactation and is 0.6 mg for infants through 12 months.
How do I find out how much manganese is in a food?
A Daily Value is a reference target, not a measurement of any particular food. To find the manganese content of a specific ingredient or product, look it up in USDA FoodData Central, then use that amount here to see what a label would declare and what %DV it carries.
Where do these numbers come from?
