Morning, with food

Common questions

Do I need iodine if I use iodised salt?

Usually not. Salt is the main source for most people.

Is kelp a good source?

Kelp iodine varies wildly and can be far too high.

Does pregnancy change the need?

Yes. Needs rise, so prenatal vitamins usually include it.
