Iodine is vital for thyroid hormone synthesis, regulating metabolism, growth, and development.
Iodine is an indispensable trace mineral required for the synthesis of thyroid hormones that govern metabolism, growth, and neurological development. Crucial for preventing goiter and supporting cognitive function, especially during pregnancy and infancy, adequate intake is vital. However, excessive iodine consumption can trigger adverse effects like iodism, thyroid dysfunction, and allergic reactions, particularly in vulnerable individuals. Dosage recommendations should be strictly followed to ensure benefits while mitigating risks.
Key Information
Inside Body Harmful Score
Common Dosage
150 mcg daily (adults); higher during pregnancy and lactation (220-290 mcg daily)
Source Type
natural
Production Process
Iodine is typically extracted from natural sources such as seawater, seaweed (kelp), and caliche ore deposits. Extraction methods include chemical oxidation and reduction processes.

Inside BodyPotential Benefits
Enhances mental processes involved in thinking, learning, and remembering, including memory, attention, focus, and processing speed. Benefits range from improved mental clarity to significant enhancements in cognitive abilities, especially in those with cognitive decline.
Supports healthy thyroid function by providing nutrients for hormone synthesis and conversion, reducing inflammation, and protecting against oxidative stress. May improve energy levels, mood, weight management, and cognitive function.
Metabolism enhancement improves the body's chemical processes, leading to increased energy, better weight management, and improved overall health. This is achieved through optimized energy production, nutrient breakdown, and waste elimination.
Iodine is vital for synthesizing thyroid hormones T4 and T3, which regulate metabolism, growth, and development. Sufficient iodine intake supports healthy thyroid function and prevents hypothyroidism.
Adequate iodine intake is crucial for thyroid hormone synthesis. This prevents the thyroid gland from enlarging (goiter) due to overstimulation from the pituitary gland when iodine is deficient.
Sufficient iodine intake during pregnancy is critical for fetal brain development and prevents neurological deficits. Iodine supports the production of thyroid hormones which are essential for healthy neurological development.
Biotin is essential for fetal development during pregnancy due to its role in metabolic processes and cell growth. Adequate biotin intake supports the healthy development of the fetus's organs and tissues.
Possible Side Effects
Thyroid dysfunction involves impaired thyroid hormone production leading to conditions like hypothyroidism or hyperthyroidism. Symptoms vary and can include fatigue, weight changes, and heart rate irregularities; long-term consequences may include cardiovascular or neurological problems.
Allergic reactions are hypersensitivity responses to allergens, ranging from mild skin irritation to life-threatening anaphylaxis. Symptoms vary widely and are caused by an immune response.
Iodism results from excessive iodine intake, causing symptoms like metallic taste, increased salivation, burning sensation, and stomach upset. In severe cases, it can lead to thyroid dysfunction or airway obstruction.
Excessive iodine intake can trigger or worsen hyperthyroidism or hypothyroidism, particularly in those with pre-existing thyroid issues. This disruption stems from iodine's impact on thyroid hormone production.
Excessive iodine intake may trigger or worsen autoimmune thyroid diseases like Hashimoto's thyroiditis or Graves' disease in susceptible individuals, leading to hypothyroidism or hyperthyroidism, respectively.
Excessive seaweed consumption can impact thyroid function due to its high iodine content, potentially leading to hyperthyroidism or hypothyroidism, especially in individuals with pre-existing thyroid conditions.
Scientific Evidence
Scientific sources include the World Health Organization (WHO), the National Institutes of Health (NIH), and various studies published in journals such as 'The Lancet', 'New England Journal of Medicine', and 'Thyroid'. Key studies investigate the effects of iodine deficiency and excess on thyroid function and cognitive development. Specific studies on iodine supplementation during pregnancy and its impact on fetal neurodevelopment are also significant.
