Description
"Iodine" is a trace mineral primarily sourced from seafood, seaweed, and iodized salt, essential for thyroid function. It facilitates the synthesis of thyroxine (T4) and triiodothyronine (T3), enabling the regulation of metabolism, growth, and neurological processes. By strengthening mucosal barriers, iodine helps sustain immune function in the respiratory and digestive systems. Its involvement in enzymatic activity allows for metabolic adaptation and physiological regulation. A critical factor in endocrine balance, iodine remains vital for energy metabolism and overall health maintenance.
Functions in the Body

Deficiency Symptoms
Iodine deficiency can cause puffy skin, a hoarse voice, impaired mental function, dry and scaly skin, sparse and coarse hair, intolerance to cold, weight gain, and goiter.
Synergists & Antagonists
Iodine supports thyroid health alongside selenium, zinc, iron, vitamin B12, and tyrosine. However, its absorption may be inhibited by fluoride, bromine, chlorine, excessive calcium, and goitrogenic foods like flaxseed flour and peanuts.

Warnings
People with Hashimoto's disease should use iodine with caution, as excess iodine can decrease thyroid function. It interacts with lithium, amiodarone, and medications for overactive thyroid conditions.
Food Sources
Iodine can be found in foods like cod, tuna, seaweed, shrimp, milk, yogurt, and cheese.
Time Frame
Iodine can be taken anytime, though consistent intake is key to maintaining thyroid function.
Depleted By
Iodine can be depleted by medications for hypothyroidism, bronchodilators, and certain other medications.
