Pharma Nord Iodine 400IU - 120 TabletsIodine is an essential trace element needed for various processes in the body. We can find it in foods such as meats, dairy & cereals - though UK agricultural soils (and therefore our locally produced foods), may not contain enough.How Does it Work?Optimum iodine status is essential for our metabolism, which governs many processes in the body, including energy-producing metabolism. Iodine also contributes to cognitive functions, nervous function and skin.Iodine is used primarily by the thyroid, which is a small gland located in the neck. The thyroid gland's main role in the body is to regulate our metabolic rate. Specifically, the thyroid uses iodine to produce thyroid gland hormones known as T3 ( triiodothyronine) and T4 (thyroxine). If the body doesn't have enough iodine, the production of these hormones can be adversely affected.The Importance of Form: Potassium IodatePure iodine wouldn't absorb well in the body. Instead, iodine supplements come in different forms (such as salts) that allow them to absorb better.Iodine 400 µg from Pharma Nord uses the potassium iodate form, rather than the more commonly used potassium iodide. Potassium iodate effectively delivers iodine to the body but is considered more stable with a longer shelf life.
