The Nutritional Health Benefits of Iodine
By John Gibb

Iodine is a trace mineral that converts to iodide in the body. There are a number of sources of iodine available. It is found in food plants, kelp, seafood, iodized salt, sea vegetables, dairy products, and regular type vegetables.. It is an important component of Thyroxin.

The benefits of Iodine are many in that it can help goiters, hypothyroidism (under-active thyroid), fibrocystic diseases, and exposure to radiation. 
The condition of hair, skin, nails and teeth can be improved with the proper amount of iodine.

Iodine is necessary for the production of thyroid hormones which are necessary for normal metabolism.

Side Effects and Deficiency

Side effects of iodine would be indicated by thyroid dysfunction, itching, rashes, and lesions on the skin. Gastro-intestinal problems and hypothyroidism are also side effects. Thyroid problems can be indicated by such things as fatigue, weight gain or loss, dry skin and goiter.

Iodine deficiency occurs with individuals who avoid seafood, dairy products, processed foods, and/or iodized salt. Children who have a deficiency may have iodine deficient anemia. This could interfere with any kind of supplementation.

While it can be consumed from food sources it can be taken in a supplement.

Precautions on using Iodine Tablets

Pregnant or nursing women should always consult with a physician before beginning taking supplements of any kind.

If you suffer from a certain health condition, please speak to your doctor about any supplements you wish to take. This is to ensure there is no dangerous interaction with any medications you may be on.
