Analysis
Life Extension's Vitamin D3 125 mcg (5000 IU) with Sea-Iodine is a well-formulated product, combining two vital nutrients: 5000 IU of Vitamin D3 and 1000mcg of Iodine derived from marine sources. Life Extension is a highly respected brand, known for its quality and research-backed supplements. The combination is particularly beneficial as both nutrients play crucial roles in immune function, bone health (D3), and thyroid metabolism (Iodine), addressing multiple health goals simultaneously. With a price per serving of $10 and over 3600 positive reviews, it offers excellent value. However, the 1000mcg iodine dose, while beneficial for some, might be considered high for individuals with lower iodine needs or existing thyroid conditions, and the combined nature means less flexibility for those who prefer to supplement D3 and iodine separately.
Pros
- Combines two essential nutrients, Vitamin D3 (5000 IU) and Iodine (1000mcg), offering comprehensive health support.
- Comes from Life Extension, a highly reputable brand known for quality and scientific formulations.
- Excellent price per serving for a combined high-potency supplement.
- High review count indicates widespread consumer satisfaction and trust.
Cons
- The 1000mcg iodine dosage might be higher than the optimal daily intake for some individuals.
- The combined formulation limits flexibility for those who prefer to dose Vitamin D3 and iodine separately.
- Not ideal for individuals who only need iodine and already have sufficient Vitamin D intake.

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.
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.
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.
