Health Benefits of Iodine
Iodine is found in food, and the body stores it in the thyroid gland. It helps the thyroid gland produce hormones that are essential for regulating metabolism. It is necessary for the proper development and functioning of the brain and nervous system. Iodine deficiency can lead to goiter, a condition in which the thyroid gland enlarges. Its deficiency can also cause intellectual disability and developmental delays in children.
Fortunately, iodine deficiency is easily preventable by consuming iodine-rich foods or taking a supplement. It is important for many reasons, including:
Used for gargles
Iodine gargles are a common home remedy for sore throats. Gargling with iodine can help to kill bacteria and reduce inflammation. Iodine gargles are generally safe, but they can cause side effects such as staining of the teeth or irritation of the throat. You can also gargle with iodine solution to soothe inflamed tonsils. (3)
Good for thyroid
The thyroid gland is responsible for producing hormones that regulate metabolism, and iodine is essential for its proper function. Without enough iodine, the thyroid cannot make enough hormones, leading to a condition called hypothyroidism. Symptoms of hypothyroidism can include fatigue, weight gain, constipation, and depression. (2)
Iodine deficiency is the most common cause of hypothyroidism worldwide, and it can be easily prevented with iodine supplementation. Most people in developed countries get enough iodine from iodized salt, but those who don’t eat much salt or who have certain medical conditions may need to take an iodine supplement.
If you think you might have hypothyroidism, it’s important to see a doctor for a diagnosis and treatment. In most cases, hypothyroidism can be easily managed with medication.
