Notes

- The above-stated values are not meant for diagnosis, these are mainly reference values for informational purposes.

- Most of these values are based on a 2000 calorie intake for people of 4 or more years of age. This reference is applied because it approximates the caloric requirements for postmenopausal women. This group has the highest risk for excessive intake of calories and fat.

- Values on labels are stated Daily Reference values (DRV) of Recommended Daily Intake (RDI). The RDI is a renewed value referring to the old Recommended Dietary Allowance (RDA). All values in this table are new RDI values.

- Maximum values are based on Food and Drug Administration (FDA) values, the World Health Organization (WHO), BBC Health values, the European Union Directive (based on FDA values) and values from various other governmental and private agencies in the USA and the UK.

- Values from the World Health Organization (WHO) may be somewhat lower than those of the FDA for various vitamins and minerals. Examples of differences (WHO values to FDA values): Mg: -60 mg, Vitamin B6: -0,5 mg, Vitamin B12: -4 µg, vitamin C: -15 mg, Vitamin K: -35 mg, folate: -220 µg.

- Elements that have a recommended daily intake within µg range are sometimes referred to as trace elements (e.g. copper, chromium, selenium).
