Iodine is an essential nutrient that is important for thyroid function and metabolism. It is needed to produce thyroid hormones, which help regulate body temperature and metabolic rate. Nearly 20-30 mg of iodine is found in the adult human body, primarily in the thyroid gland. Important dietary sources of iodine include seaweed, seafood, dairy products, and iodized salt. Iodine deficiency can lead to thyroid disorders, cognitive issues, goiter and irreversible effects on growth and development. The recommended daily intake of iodine varies from 110-150 mcg depending on age.

3. INTRODUCTION
 Defination :- it is an essential component of the thyroid hormone which are vital
regulator of basal metabolic rate and physical and mental development.
 Nearly 20-30 mg of iodine present in adult humans body.
 It can mostly be found within our thyroid gland and during our body synthesis of
thyroid hormones.

4. IMPORTANCE OF IODINE
 Iodine is an important for our body because it is a component of thyroid hormone
 These hormone help to regulate our body temperature and our metabolic rate.
 It is support various bodily functions.
 Iodine deficiency can lead to thyroid disorders , cognitive issues and even goiter
 To prevent these health problems, it’s important to ensure an adequate intake of
iodine through diet or supplementation.

5. • SOURCES OF IODINE
 Food :-
 Seaweed (such as kelp) seafood, dairy products
 Iodine is primarily sourced from natureal sources like seawater and underground

7. FUNCTIONS OF IODINE
 Needed to produce the thyroid hormone which is
 support our thyroid function
 Support our health growth and development
 regulate our overall metabolism
 mainten our energy levels
 regulate our body temperature 🌡🦐🦐

8. IODINE DEFICIENCY
 Iodine deficiency has Multiple adverse effects on growth and development and is
the most common cause of preventable mental retardation in the world 🌍🌎
 Resultedmainly from inadequate thyroid hormone production during pregnancy
and early infancy,
 Iodine deficiency can cause irreversible effects
 Under normal conditions the body tightly control 🛂 thyroid hormone
concentration via TSH
 If Iodine intake falls below approximately 10-20 mcg /day is called hypothyroidism
occurs
 GOITER is the earliest clinical sign of iodine deficiency.
