What Is Iodine?

Iodine is a vital mineral that plays a crucial role in various bodily functions.

It is an essential component of thyroid hormones, which regulate metabolism and contribute to hair growth.

Our bodies do not naturally produce iodine, so we need to obtain it through our diet or supplements.(1)


What is Iodine

Why Is Iodine Important?

Iodine is essential for maintaining healthy hair growth.

It helps to regulate the functioning of the thyroid gland, which produces hormones that influence the growth and development of hair follicles.

Insufficient iodine levels may lead to hair loss or thinning hair.(2)


How Does Iodine Work?

Iodine supports hair growth by ensuring optimal thyroid function.

The thyroid gland produces hormones that control the metabolic rate of cells, including those in hair follicles.

These hormones help regulate the hair growth cycle, promoting the growth of strong and healthy hair.

How Is Iodine Extracted From Natural Sources?

Iodine can be extracted from different natural sources, primarily from seawater and underground brines.

Here's a general overview of the extraction process:


Seawater Extraction

Seawater contains trace amounts of iodine.

It is first collected and concentrated in large pools called evaporation ponds.


  • Seawater is pumped into these ponds and exposed to sunlight and wind, promoting evaporation.
  • As water evaporates, the iodine concentration increases.
  • Once the concentration is sufficient, the remaining solution is treated with chemicals to precipitate iodine crystals.
  • The crystals are then collected, washed, and purified to obtain pure iodine.


Underground Brine Extraction

Certain underground deposits, such as those found in salt domes or wells, contain brines rich in iodine.


  • Brine is pumped to the surface and undergoes a series of filtration and purification steps.
  • The brine is treated with oxidizing agents to convert iodide ions into iodine.
  • The resulting iodine is further processed to remove impurities and obtain the final iodine product.

Can Excessive Iodine Intake Be Harmful?

Yes, excessive iodine intake can have adverse effects on health.

It is important to maintain a balance and avoid exceeding the recommended daily intake.

Here are some potential risks of excessive iodine consumption:


Thyroid Dysfunction

High levels of iodine can disrupt thyroid function, leading to hyperthyroidism or hypothyroidism.

Autoimmune Thyroiditis

Excessive iodine intake may trigger or worsen autoimmune thyroid diseases, such as Hashimoto's thyroiditis or Graves' disease.

Goiter Formation

In some cases, excessive iodine can cause the thyroid gland to enlarge, resulting in a condition known as goiter.

Thyroid Cancer

Prolonged exposure to high iodine levels may increase the risk of thyroid cancer, although this risk is relatively low.


Can Iodine Have An Impact On Pregnancy And Fetal Development?

Yes, iodine plays a crucial role in pregnancy and fetal development.

Adequate iodine levels are essential for the healthy growth and development of the baby.

Here are some key points to consider:


Thyroid Hormone Production

Iodine is necessary for the production of thyroid hormones, which are crucial for the developing baby's brain development and overall growth.

Maternal Health

During pregnancy, the demand for iodine increases.

Insufficient iodine intake can lead to maternal thyroid dysfunction and may have adverse effects on both the mother and the baby.

Neurological Development

Iodine deficiency during pregnancy can result in intellectual and developmental disabilities in the child, known as congenital hypothyroidism.

Miscarriage And Stillbirth

Severe iodine deficiency increases the risk of miscarriage, stillbirth, and other pregnancy complications.
