Supplements are gaining popularity. Even professionals recommend people should take dietary supplements on a regular basis. Nevertheless, iodine is one of the elements that should be taken with caution. Use it only after talking to your doctor. Iodine influences how the thyroid gland operates and is responsible for the hormone production and balance in your body. Make sure you need iodine since too much or too little of the mineral in your body may lead to hypothyroidism. Your iodine levels can be measured. Take tests and let specialists examine you.
