Iodine is a mineral that’s found in soil, sea water as well as plants and animal products.
What is iodine used for?
Iodine is needed by the thyroid gland to produce the hormones used all over the body. These hormones help produce energy from fat, control cholesterol levels and keep weight stable, as well as nerves and bone health, and keeping skin, hair, nails and teeth in good condition.
What’s the best way to take iodine?
As your body doesn’t make iodine you need to get it through your diet. You can get iodine by eating fish, eggs, nuts, meat, bread, dairy products, seaweed and iodized table salt.
You can also take a supplement – look for one containing potassium as this helps your body absorb the iodine.
Is iodine essential?
Yes, it is. If you have an iodine deficiency it can impact your thyroid gland. It swells up trying to extract more iodine from the blood (known as goitre) and you may suffer side effects such as constipation, fatigue, thinning hair, weakness, mental slowing, obesity.
Adults need 150mcg per day. And while iodine deficiency isn’t common in the western world, it can occur if you lack an adequate diet. Vegans and vegetarians are slightly more at risk.
