Tolerable Upper Limit
There is also a tolerable upper limit for iodine - this is the maximum that can be safely taken of this mineral before it produces serious and toxic side effects:
- Infants (0- 12 months) - not established*
- Children (1-3 years) - 200mcg
- Children (4-8 years) - 300mcg
- Children (9-13 years) - 600mcg
- Children (14-18 years) - 900mcg
- Adults (>19 years) - 11000mcg (1.1mg)
- Pregnant and lactating women (<18 years) - 900mcg
- Pregnant and lactating women (19-50 years) - 11000mcg (1.1mg)
* The tolerable upper limit for iodine for infants aged 0-12 months has not yet been determined due to a lack of data about the adverse effects in this age group and a concern about the lack of ability of the body of infants to handle excess amounts. The only source of iodine intake should be from food (breast milk and/or baby formula) to prevent high levels of intake and possible adverse effects.
