Key Ingredients and Their Roles

Vitamin D3 (cholecalciferol) is the preferred form of vitamin D, easily utilised by the body. It contributes to the normal absorption and utilisation of calcium and phosphorus, and to the maintenance of normal bones.* Vitamin K works synergistically with vitamin D, directing calcium to bones and teeth away from soft tissues; it also contributes to normal blood clotting.* Iodine, sourced from sea-iodine, contributes to normal cognitive function, normal energy-yielding metabolism, and normal production of thyroid hormones.* Together, these three nutrients form a comprehensive foundation for wellness.

How Does This Supplement Support Your Health?

Vitamin D and K are well known for their roles in bone health: vitamin D helps maintain normal bone density as you age, while vitamin K supports normal arterial flexibility.* Iodine is critical for thyroid function, influencing energy levels and metabolic balance.* By combining these in one formulation, Life Extension offers a targeted approach to supporting these interconnected systems. Each daily capsule provides 125 mcg (5,000 IU) of vitamin D3, 2,100 mcg of vitamin K, and 1,000 mcg of iodine.

Who Can Benefit from This Supplement?

This supplement is ideal for anyone looking to fill nutritional gaps, particularly those with limited sun exposure (which reduces vitamin D synthesis), individuals over 50, or those following a diet low in iodine-rich foods like seafood. It also suits those who want to support bone health, thyroid function, and cardiovascular wellness with a simple daily routine. Always consult a health care professional before starting any new supplement regimen, especially if you are pregnant, nursing, or taking medication.

What Makes Life Extension Vitamins D and K with Sea-Iodine Unique?

This advanced formula combines three essential nutrients—vitamin D3, vitamin K, and iodine—in a single, convenient capsule. Each ingredient is carefully selected for quality and bioavailability, helping you maintain bone density, cognitive function, thyroid health, and vascular integrity.*

Frequently Asked Questions

Can I take this supplement with other vitamins?

Yes, but be mindful of your total vitamin D intake as many multivitamins already contain vitamin D. If you are taking blood thinners, consult your doctor due to vitamin K's role in clotting.

How should I take it?

Take one capsule daily with a meal for optimal absorption. The pack contains two bottles of 60 capsules each, providing a four-month supply.
