insights Analysis
Life Extension's Sea-Iodine delivers a potent 1000mcg of iodine, approaching the tolerable upper intake level, making it primarily suited for individuals with confirmed deficiencies or specific medical requirements under professional guidance rather than routine supplementation. Life Extension is renowned for its scientifically-backed and rigorously tested formulations, which is crucial for such a high-dose product. However, the relatively low serving count of 60 and a high price per serving (10) makes it less cost-effective for general daily use compared to lower-dose alternatives, emphasizing its specialized nature.
- Offers a high 1000mcg dose for individuals with significant iodine deficiencies or specific medical needs.
- Produced by Life Extension, a brand highly regarded for its research-backed formulations and quality control.
- Precise dosing, likely from a consistent source like potassium iodide, offering reliability for targeted supplementation.
- The 1000mcg dose is very high and can be excessive for general daily use, potentially leading to adverse effects for some individuals.
- High price per serving (10) makes it less economical for long-term, continuous supplementation compared to moderate-dose alternatives.
- Limited servings (60) mean more frequent repurchases for daily users.

bolt Effectiveness for goals
Iodine is an essential trace element primarily recognized for its critical role in the production of thyroid hormones. These hormones are fundamental for regulating metabolism, growth, and development throughout the body. Adequate iodine intake is necessary to support these vital functions.
Iodine is an essential trace element crucial for the synthesis of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). These hormones regulate numerous metabolic processes, growth, and development throughout the body. Adequate iodine intake is therefore critical for proper thyroid function.
Yes, iodine is a key component required for the thyroid gland to synthesize thyroid hormones effectively. Proper iodine levels are crucial for maintaining normal thyroid function. Both insufficient and excessive iodine intake can potentially affect thyroid health.
Yes, iodine supplementation is highly effective in correcting iodine deficiency, which can lead to conditions like goiter and hypothyroidism. In populations with insufficient dietary intake, fortified salt and supplements are primary strategies to ensure adequate iodine levels. This helps restore normal thyroid function and prevent associated health issues.
Iodine supplementation is highly effective in preventing and correcting iodine deficiency, especially in populations with low dietary intake. Public health initiatives, such as universal salt iodization, have significantly reduced the prevalence of iodine deficiency globally. Regular, adequate intake ensures the body has enough iodine.
schedule Dosage, timing & forms
The Recommended Dietary Allowance (RDA) for iodine for most adult men and non-pregnant, non-lactating women is 150 micrograms (mcg) per day. For pregnant women, the RDA is 220 mcg per day, and for lactating women, it is 290 mcg per day. These recommendations are designed to meet the nutritional needs of most healthy individuals.
The recommended daily intake for iodine in adult men and women is generally 150 micrograms (mcg). This amount is considered sufficient to meet the nutritional needs of most healthy individuals. Adequate iodine intake is crucial for normal thyroid function.
The Tolerable Upper Intake Level (UL) for iodine for adults, including pregnant and lactating women, is 1,100 micrograms (mcg) per day. This UL is established to help prevent potential adverse effects from excessive intake. Consuming amounts above this level may carry risks, particularly for individuals with pre-existing thyroid conditions.
During pregnancy, the recommended daily iodine intake increases to 220 mcg, and during lactation, it is 290 mcg per day. These higher amounts support the increased demands of the mother and the developing fetus or nursing infant. Adequate iodine is vital for proper neurological development.
Iodine supplements can potentially interact with certain medications, particularly antithyroid medications, ACE inhibitors, and potassium-sparing diuretics. Individuals taking any prescription medications, especially those for thyroid conditions, should consult a healthcare professional before starting iodine supplementation. This is to ensure safe and appropriate use.
health_and_safety Safety & interactions
Individuals with pre-existing thyroid conditions, such as an overactive or underactive thyroid, should exercise caution with iodine supplements. Excessive iodine can worsen hyperthyroidism or induce hypothyroidism in susceptible individuals. It is crucial to consult a healthcare professional before starting iodine supplementation to avoid adverse effects.
In individuals with pre-existing thyroid conditions, particularly autoimmune thyroid diseases, iodine supplementation can potentially exacerbate the condition. It may induce hyperthyroidism or hypothyroidism, depending on the individual's sensitivity and the dose. Consulting a healthcare professional is crucial for individuals with thyroid issues.
Excessive iodine intake can disrupt thyroid function, potentially leading to both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), as well as goiter. Symptoms may include a metallic taste, nausea, diarrhea, and abdominal pain. The tolerable upper intake level (UL) for adults is generally set at 1,100 micrograms (mcg) per day.
For individuals with autoimmune thyroid diseases, iodine intake requires careful consideration. High iodine intake may trigger or exacerbate autoimmune thyroiditis in susceptible individuals, particularly those with Hashimoto's. While iodine is essential, supplementation should only be undertaken under strict medical supervision due to the potential for adverse effects on thyroid function.
Individuals with pre-existing thyroid disorders, kidney disease, or iodine sensitivity should exercise caution. Pregnant and breastfeeding women should consult a healthcare professional regarding appropriate iodine intake. Individuals on certain medications should also seek medical advice.

Categories
Iodine 75.0
As an iodine supplement, it provides a very high and precise dose, which is effective for severe deficiencies. However, its suitability within the general iodine category is limited by this high potency, making it a specialized product rather than a universally recommended option.
Goals
Brain Health 70.0
Iodine is essential for cognitive function, but excessive amounts do not necessarily provide added benefits and could be counterproductive, so the high dose is only 'better' for specific deficiency states impacting brain health.
Productivity Boost 70.0
Iodine supports energy through thyroid function, but consuming very high doses beyond what's needed may not further boost productivity and could lead to imbalances affecting energy levels.
Metabolism Boost 70.0
Iodine is crucial for metabolic regulation, yet this extreme dose is more for correcting severe deficiencies rather than simply 'boosting' metabolism beyond what a lower, more balanced dose would provide.
