Have you heard about iodine supplements, and are wondering if you should be taking them? This article aims to be a basic guide to iodine, but the decision about whether to take iodine should be based on a discussion with your healthcare professional.
What is iodine?
Iodine is a mineral essential to the health and development of thyroid hormones, which help with metabolism. They also ensure proper bone and brain development during pregnancy and infancy.
How much iodine do I need?
You don't need a whole lot of iodine to function, but iodine deficiency can be a concern – especially in pregnant women – as it can cause significant and permanent damage to the unborn baby.
How much iodine you need depends on your age and life stage. For instance, babies younger than 6 months need 110 micrograms a day. Teenagers need 150 micrograms a day, while pregnant women need 220 mcg (and 290 mcg when breastfeeding). In the United States, research has found that many pregnant women aren't getting enough iodine; they need around 50 percent more than non-pregnant women.
There are concerns that iodine deficiency is on the rise, thanks to a modern diet of processed foods that don't contain iodised salt.
How can I get iodine?
Iodine is available in many foods including vegetables, fruits, dairy and fish. Interestingly, the amount of iodine we get from fresh foods depends on the soil in which they are grown. And unless you grow produce at home, this can be hard to ascertain.
During times of widespread iodine deficiency, governments will often intervene. Back in the 1920s, for instance, the New Zealand government iodised table salt to boost Kiwis' iodine intake. So an easy way to get an extra boost of iodine is by adding iodised salt to your food.
Should I take iodine supplements?
You can also use iodine supplements (either singularly, or as part of a multi-mineral supplement).
You might need to take iodine supplements if you live in an area with iodine-deficient soil. A diet high in processed foods may also leave your iodine levels low.
If you're concerned about your iodine levels, consult a healthcare professional such as a GP, naturopath, or nutritionist. As well as testing your levels, they can suggest ways to boost your iodine levels.
