What are the non-dairy sources of iodine?
Plant-based drinks
Plant-based drinks are a useful source of iodine in a dairy-free diet, but be careful to check the nutrition labels. Not all brands are regularly fortified with vitamins and minerals and organic brands rarely do. You will need to look even harder for brands with iodine fortification.
Remember, only children over the age of 12-18 months can be switched from formula to a plant-based drink as their main drink, so do work with a registered paediatric dietitian who will guide you with this important decision.
According to product labels, M&S plant-based drinks are a good match to cow’s milk, however, more research is needed as to how plant-based drinks are fortified with iodine. Potassium iodide is the usual choice added to plant drinks.
Note that taking high doses of iodine for long periods of time can affect the way your thyroid works so please always consult with a registered medical professional before starting any type of iodine supplement for you or your child.
Contrary to popular claims, note that sea salt/Himalayan salt are not a good source of iodine. You can buy iodised salt, but do use this sparingly to abide by the national recommendations for salt.
Some countries like Australia and New Zealand have an iodised salt policy with flours iodised salt used in bakery. This is currently not in place in the UK.
