Hello This is Jinny , the pharmacist .

Did you know that iodine is an essential nutrient that is likely to be deficient worldwide regardless of the health care level of each country Iodine is a mineral that is abundantly contained in seaweeds such as kelp and seaweed, and is a nutrient that is easily deficient depending on eating habits .

Iodine is required to synthesize the thyroid hormone thyroxine, and its deficiency can cause goiter, so it is widely known as an essential nutrient that contributes to thyroid health . Thyroid hormone is involved in energy metabolism by controlling the body's metabolic rate, and is important for the development of the central nervous system by promoting mRNA and protein synthesis .

However, iodine has various benefits besides thyroid health . Today , I would like to introduce the various functions of iodine, an essential nutrient, through a thesis .

1. Antioxidants 

In 2015 Natural Science published a review article summarizing and reporting the results of approximately 50 years of academic research on the role of iodine in defense mechanisms against various diseases and the benefits of iodine in body tissues other than the thyroid .

The most noteworthy benefit of iodine in this paper is its antioxidant properties .

"Iodine has a protective function against free radicals and peroxides. This can be observed in vitro by reducing the depolymerization of hyaluronic acid and increasing the antioxidant status of human serum, increasing the activity of antioxidant enzymes in vivo and reducing malondialdehyde and peroxides. .”

2. Antitumor 

The immune system plays an important factor not only in basic health, but also in tumor progression or regression . Research on the relationship between iodine and immune regulation has been continuously accumulated since the 1980s , and naturally , academic studies have been conducted to determine the relationship between iodine supplementation and anti-tumor immune response .

In 2019 BMC Cancer published a paper reporting the results of in vitro and in vivo observations of the effect of iodine on human breast cancer cell lines with high metastatic potential .

“ Supplementation of iodine reduces the invasive potential of triple-negative basal cancer cells under in vivo and in vitro conditions. Furthermore, oral supplementation of iodine prevents tumorigenic progression by activating antitumor immune responses in both types of breast cancer cells."

(2019). Molecular iodine exerts antineoplastic effects by diminishing proliferation and invasive potential and activating the immune response in mammary cancer xenografts. BMC cancer, 19(1), 1-12.
3. Improve cognitive abilities

Common iodine deficiency disorders are goiter and cretinism While the risks of severe iodine deficiency are well known the effects of mild iodine deficiency are not well known . Finally, let 's look at the effects of mild iodine deficiency and the benefits of iodine supplementation at this time .

In 2009 The American journal of clinical nutrition published  a paper reporting the results of a randomized placebo -controlled , double-blind trial evaluating the effects of iodine supplementation in 184 New Zealand children aged 10 to 13 years .

" Iodine supplementation improved perceptual reasoning in mildly iodine-deficient children, suggesting that mild iodine deficiency may prevent children from achieving their full intellectual potential."
Reference paper: Gordon, RC, Rose, MC, Skeaff, SA, Gray, AR, Morgan, KM, & Ruffman, T. (2009). Iodine supplementation improves cognition in mildly iodine-deficient children. The American journal of clinical nutrition, 90(5), 1264-1271.

Today we looked at the many benefits of iodine that have been validated by the scientific community According to the Korean Dietary Reference Intakes Guidelines, the recommended daily intake of iodine for male and female adults and the elderly in Korea is 150 ㎍ pregnant women 240 ㎍ and lactating women 330 ㎍ .

I hope you have a healthy day in body and mind It was Jinny .
