Quick answer
Iodine is an essential mineral. In Australia, iodised salt has been required in most commercial bread since 2009, and iodine is also found in seafood, seaweed, dairy and eggs. Iodine supplements, such as MAYN Iodine Liquid Drops (150mcg per serve), are measured in micrograms.

Why is iodine added to bread in Australia?
Since October 2009, bakers in Australia have been required to use iodised salt in most bread (organic bread is an exception). The rule was introduced because many Australians weren't getting enough iodine from food alone.
Iodine-rich foods
| Food | Iodine |
|---|---|
| Seaweed | Very high (varies widely) |
| Seafood and fish | High |
| Dairy | Moderate |
| Eggs | Moderate |
| Bread made with iodised salt | Moderate |
| Iodised table salt | Contains added iodine |
Iodine drops: how they're measured
Iodine is needed in tiny amounts, so it's measured in micrograms (mcg). One microgram is a thousandth of a milligram. MAYN Iodine Liquid Drops provide 150mcg per serve.
More iodine isn't better. Too much iodine can be harmful, so follow the label directions and talk to your doctor, especially if you have a thyroid condition or are pregnant or breastfeeding.
Frequently asked questions
Is sea salt iodised?
Not usually. Unless the label says iodised, sea salt and rock salt generally don't contain added iodine.
Is all bread in Australia fortified with iodine?
Most commercial bread must be made with iodised salt. Organic bread is exempt.
What's the difference between mcg and mg?
1mg equals 1000mcg. Iodine is measured in mcg because only tiny amounts are needed.
