What is iodine and what does it do?
Iodine is an essential trace mineral required for the production of thyroid hormones. These hormones contribute to normal metabolism, growth and development. Iodine must come from the diet or other external sources because the body does not produce it.
What are the benefits of iodine supplements?
The recommended benefits depend on the individual product. Licensed Canadian iodine supplements may be authorized to help support normal thyroid gland function and help prevent iodine deficiency. Check the specific product’s NPN for its authorized use.
How much iodine do adults need per day?
The recommended dietary allowance for most adults is approximately 150 mcg per day from food, beverages and supplements combined. Pregnancy and breastfeeding increase iodine requirements. This does not mean everyone needs a 150 mcg supplement.
Does iodine help the thyroid?
Iodine is required for normal thyroid hormone production and normal thyroid function. However, taking additional iodine does not automatically improve thyroid function, and too much iodine can also cause thyroid problems. People with diagnosed thyroid conditions should seek professional guidance before supplementing.
Can iodine help hypothyroidism?
Iodine deficiency can contribute to impaired thyroid function, but iodine supplementation is not a general treatment for hypothyroidism. Many cases of hypothyroidism have causes unrelated to iodine deficiency, and excess iodine may worsen certain thyroid conditions. Speak with your healthcare professional before using iodine specifically for a thyroid disorder.
What is the difference between iodine and kelp supplements?
Iodine is the mineral itself, while kelp is a seaweed that naturally contains iodine. Kelp supplements may provide iodine along with other naturally occurring components. Compare the labelled amount of iodine per serving rather than choosing only by the amount of kelp.
Are liquid iodine drops better than tablets?
Neither format is automatically better. Liquid iodine drops offer a convenient format, while tablets provide a fixed serving. The more important factors are the amount of iodine, iodine source, serving directions, ingredients and product licence.
What is potassium iodide?
Potassium iodide is a compound that provides iodine and is used in some nutritional iodine supplements. High-dose potassium iodide products used during certain nuclear emergencies are very different from everyday nutritional iodine supplements and should only be used when instructed by public-health authorities.
Can too much iodine be harmful?
Yes. Excessive iodine intake can interfere with thyroid function, just as iodine deficiency can. The adult tolerable upper intake level is 1,100 mcg per day from all dietary sources, although some people with thyroid conditions may be sensitive to lower amounts.
