Vitamins D and K with Sea-Iodine – 60 Caps

Life Extension Vitamins D and K with Sea-Iodine is a comprehensive formula delivering three essential nutrients in a single daily capsule. Each serving provides a meaningful dose of Vitamin D3 as cholecalciferol, a highly bioavailable form, alongside a full-spectrum Vitamin K complex and natural iodine sourced from organic sea vegetables — supporting key physiological functions that many people struggle to obtain sufficiently from diet alone.

What sets this formula apart is its multi-form Vitamin K profile, combining Vitamin K1 (phytonadione) with two distinct forms of Vitamin K2 — menaquinone-4 and the longer-acting all-trans menaquinone-7. Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus, normal blood calcium levels, and the maintenance of normal bones, teeth, and muscle function. Vitamin K contributes to normal blood clotting and the maintenance of normal bones. Iodine contributes to normal thyroid function, normal production of thyroid hormones, and normal cognitive and energy-yielding metabolism.

The iodine in this product is delivered via Life Extension’s proprietary Sea-Iodine Complex Blend, derived from organic kelp and bladderwrack extracts combined with potassium iodide — a natural, food-based approach to iodine supplementation. Presented in easy-to-swallow vegetable capsules, this product is suitable for vegetarians and free from gluten and lactose.
