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.

Vitamin K 95
With 2100mcg of Vitamin K, this product provides a very substantial and likely comprehensive dose, positioning it as a top-tier option for targeting Vitamin K related health benefits like bone and arterial health.
Iodine 80
The 1000mcg Sea-Iodine complex delivers a significant amount of iodine, highly beneficial for those with deficiency or specific needs, but it's important to note this dose is considerably higher than the average daily requirement and should be considered carefully.
Goals
The very high dose of 2100mcg of Vitamin K, particularly if it includes K2 forms as expected from Life Extension, is highly effective for activating proteins like osteocalcin, crucial for directing calcium into bones and supporting bone density.
Vitamin K, especially K2, is vital for preventing arterial calcification by activating matrix Gla protein (MGP), which inhibits calcium deposition in soft tissues, thus providing strong cardiovascular support. The high dose contributes significantly to this benefit.
The substantial Vitamin K content plays a critical role in maintaining arterial flexibility and preventing the hardening of arteries, which is a key aspect of cardiovascular health and disease prevention.
