Whose reference values?
Daily total by nutrient
When vitamin or mineral amounts are found in your supplements, the daily totals appear here.
Totals include supplements only. You also get vitamins and minerals from food, so your real intake is higher. (The upper levels for magnesium and folic acid apply to supplements and fortified foods.)
Same ingredient in more than one product
No ingredient is in two or more products.
