insights Analysis
This Life Extension product is formulated with a robust 2100mcg of Vitamin K, indicating a strong focus on bone and cardiovascular health. While the specific form of Vitamin K isn't detailed beyond 'null', Life Extension typically uses advanced, synergistic forms like K1 and various K2 forms (MK-4, MK-7) in their comprehensive K supplements, which would be highly beneficial for calcium regulation and arterial health. The inclusion of 1000mcg of Sea-Iodine provides substantial support for thyroid function and metabolism. However, this iodine dose is significantly higher than the recommended daily allowance (RDA) of 150mcg and is near the upper intake level (UL) of 1100mcg, potentially posing risks for individuals with pre-existing thyroid conditions or those sensitive to high iodine intake. The high volume of positive reviews suggests efficacy for its target audience.
- Very high and likely comprehensive dose of Vitamin K for robust bone and cardiovascular support.
- Generous dose of Iodine supports thyroid function and metabolic health.
- Reputable brand known for advanced formulations and quality ingredients.
- Excellent price per serving for the high concentration of active ingredients.
- The 1000mcg Iodine dose is significantly above the RDA and close to the UL, which may be excessive or problematic for some users, especially without medical consultation.
- Lack of specificity for the 'Form' of Vitamin K on the label is not ideal for transparency, although the brand generally uses effective forms.
- Not suitable for individuals looking for a balanced daily multivitamin due to the high, targeted dosages.

bolt Effectiveness for goals
Iodine is a crucial component of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). The thyroid gland uses iodine to synthesize these hormones, which regulate metabolism, growth, and development. Insufficient iodine can impair thyroid hormone production.
Vitamin K is essential for the production of several proteins involved in the coagulation cascade, including prothrombin. These proteins are crucial for forming blood clots to stop bleeding. Without adequate Vitamin K, the body cannot effectively produce these clotting factors.
Yes, Vitamin K directly interacts with anticoagulant medications, such as warfarin, by counteracting their blood-thinning effects. Individuals on these medications should maintain a consistent Vitamin K intake and consult their healthcare provider before supplementing. This interaction can alter medication effectiveness.
Yes, adequate iodine is critical for normal brain development in fetuses, infants, and young children. Thyroid hormones, which require iodine, are vital for neuronal migration, myelination, and overall brain maturation. Iodine deficiency during these periods can lead to irreversible cognitive impairments.
Vitamin K, particularly Vitamin K2, activates proteins like osteocalcin, which helps bind calcium to the bone matrix. This process is important for maintaining bone density and strength. Adequate Vitamin K intake is associated with supporting healthy bones.
schedule Dosage, timing & forms
There are no well-documented direct interactions between Vitamin K and Iodine supplements that significantly impair the absorption or efficacy of either when taken at recommended dosages. Both nutrients function independently in distinct biological pathways.
Typical adult dosages for Vitamin K can vary, with K1 often around 90-120 mcg and K2 (MK-7) dosages sometimes ranging from 45-180 mcg or higher. Always refer to product labels and consult a healthcare professional for personalized guidance.
The Recommended Dietary Allowance (RDA) for iodine in adults is 150 mcg per day. Supplement dosages vary, but it's important not to exceed the Tolerable Upper Intake Level (UL) of 1,100 mcg/day for adults without medical supervision.
Yes, Vitamin K and Iodine supplements can generally be taken simultaneously. There are no known contraindications or concerns regarding their concurrent administration when each is taken according to its product instructions.
Vitamin K supplements typically contain phylloquinone (K1) or menaquinones (K2). K2 is often further categorized into forms like MK-4 and MK-7, which differ in their chemical structure and biological half-life.
health_and_safety Safety & interactions
Yes, Vitamin K plays a crucial role in blood clotting and can reduce the effectiveness of anticoagulant medications such as Warfarin. Individuals taking these medications should monitor their Vitamin K intake carefully and consult their healthcare provider. Maintaining a consistent Vitamin K intake is often advised.
Yes, iodine is essential for thyroid hormone production, and taking iodine supplements while on thyroid medication can affect thyroid function. This interaction might alter the required dosage of thyroid hormones. It is important to consult a healthcare professional before combining them.
Excessive iodine intake can lead to thyroid dysfunction, including both hypo- and hyperthyroidism, and can exacerbate existing thyroid conditions. Symptoms may include goiter, thyroiditis, or altered thyroid hormone levels. It is important to adhere to recommended daily allowances.
Vitamin K is generally considered safe for most healthy adults when taken within recommended dietary allowances or as directed by a healthcare professional. High doses are typically not associated with toxicity in healthy individuals. However, interactions with certain medications are a concern.
Individuals with pre-existing thyroid conditions, such as autoimmune thyroiditis, or those with a history of iodine sensitivity should be cautious. Pregnant or breastfeeding women should also consult a healthcare provider to determine appropriate dosages.
