You may remember iodine from chemistry lessons, but it's also an essential mineral your body genuinely can't do without. It's best known for its role in producing thyroid hormones, which regulate your metabolism, growth and energy levels, and it also contributes to normal cognitive function, the normal functioning of the nervous system, and the maintenance of normal skin.
Your body can't produce iodine, so it all has to come from your diet or supplements. In the UK, most of our intake comes from milk, dairy, eggs and fish – which means anyone following a vegan diet, or avoiding dairy and seafood, can find it harder to get enough of this essential mineral.
