11 Best Iodine Supplements
Iodine deficiency develops when you do not obtain enough iodine from your food or supplements.

Iodine is an important mineral that your body requires to function correctly. You cannot produce it on your own and must obtain it from your food or as a supplement.

Iodine is required for thyroid function. The thyroid is a butterfly-shaped gland in the neck that generates hormones to control metabolism (including the conversion of food to energy).

  • Iodine is found in foods, but the levels might be difficult to determine.
  • In the United States, the principal source of this mineral is iodized salt.
  • To get adequate iodine in the diet, people should use iodized salt daily.

What is the daily recommendation for iodine?

Iodine deficiency can develop when a person does not get enough iodine from their food or supplements.

The quantity of iodine you require fluctuates with time. The requirement of iodine for most healthy people is 150 mcg per day. However, the iodine dietary allowance for people varies with age.

Table. Recommended Dietary Allowances (RDAs) of iodine according to age
Age Recommended Dietary Allowances (RDAs) of iodine
Infant to six months 110 mcg
Baby 7 to 12 months 130 mcg
1 to 8 years 90 mcg
9 to 13 years 120 mcg
14 years and older 150 mcg
Pregnant women 220 mcg
Lactating women 290 mcg

7 signs and symptoms of iodine deficiency

  1. Cold intolerance
    • Low thyroid hormone levels can impair metabolism and cause reduced heat generation, making you more vulnerable to cold.
    • Furthermore, a low metabolic rate and body temperature might make you more susceptible to feeling chilly.
    • Cold intolerance is observed in about 84 percent of people with low thyroid hormone levels.
  2. Unexplained weight gain
    • Thyroid hormones regulate metabolism.
    • Thus, iodine deficiency results in low amounts of thyroid hormones, which impact the rate at which the body burns calories.
    • Burning fewer calories implies increased stores of fat in the body, which eventually leads to weight gain.
    • Low thyroid hormone levels may make you prone to fluid retention in the body (swelling or edema) that may contribute to weight gain.
  3. Hair loss
    • Low thyroid levels can result in hair loss because thyroid hormones promote hair follicle development.
    • Iodine deficiency and subsequent low thyroid hormone levels can affect the hair follicles, resulting in considerable hair loss over time.
  4. Neck swelling
    • The most prevalent sign of iodine deficiency is swelling of the neck or goiter.
    • When the body is deficient in iodine, the thyroid gland fails to produce enough thyroid hormones to fulfill demand.
    • To fulfill the demand, the gland works harder, forcing the thyroid cells to expand and multiply, causing the gland to enlarge in size and resulting in neck swelling.
  5. Weakness
    • Thyroid hormones maintain energy levels in the body.
    • Thus, with iodine deficiency and low thyroid hormones, you constantly feel fatigued.
  6. Impaired memory
    • It is believed that iodine deficiency in children can induce brain damage.
    • This leads to learning disabilities and psychomotor impairment, including:
      • Trouble remembering (memory)
      • Speaking
      • Talking
      • Thinking
    • A lack of iodine can result in cognitive impairment because brain growth and development are impaired.
    • Furthermore, a lack of thyroid hormones in the developing brain might result in mental retardation.
    • Brain damage and permanent mental retardation of the growing fetus are two of the most common side effects caused by iodine deficiency in pregnant women.
  7. Dry skin
    • Studies suggest that people with low thyroid hormone levels may have dry and rough skin.
    • Thyroid hormones help regenerate skin cells, but they help keep the skin moist by regulating the sweat mechanism.
    • Thus, those with low thyroid levels sweat less, making them more prone to dry skin.
