Product Overview

Life Extension Vitamins D and K with Sea-Iodine is a thoughtfully designed supplement that combines three essential nutrients to support multiple aspects of your health. Vitamin D3 (as cholecalciferol) is crucial for calcium absorption, immune function, and bone health. Vitamin K2 (as menaquinone-7) works synergistically with vitamin D to direct calcium to the bones and teeth, away from soft tissues. Sea iodine, derived from kelp, provides essential support for thyroid hormone production, which regulates metabolism. Together, these nutrients offer a convenient way to fill common nutritional gaps.

Key Features and Benefits

  • Bone Health Support: Vitamin D promotes calcium absorption, while vitamin K2 activates osteocalcin to bind calcium to the bone matrix, reducing the risk of fractures.
  • Immune Function: Vitamin D is a key modulator of immune response, helping to defend against seasonal challenges.
  • Thyroid Support: Iodine is essential for the synthesis of thyroid hormones T3 and T4, which regulate energy, metabolism, and growth.
  • Convenient Dosage: One capsule per day provides a balanced combination, making it easy to maintain consistent intake.
  • High Quality: Manufactured in facilities that follow strict quality control standards, with ingredients tested for purity and potency.

How to Use

Take one (1) capsule daily with food, or as recommended by a healthcare professional. For optimal absorption, take with a meal containing fat. Store in a cool, dry place away from direct sunlight.

Who It Is For

This supplement is ideal for adults who want to support bone density, immune health, and thyroid function. It is especially beneficial for individuals with limited sun exposure, those following a plant-based diet (iodine from kelp is plant-based), or anyone looking to ensure adequate intake of these often-deficient nutrients. Not suitable for children without professional guidance.

Why Choose This Product

Life Extension is a trusted brand with decades of experience in nutritional science. This formula combines three critical nutrients in optimal dosages based on research. The inclusion of sea iodine from kelp provides a natural source of iodine, avoiding synthetic forms. The synergy between vitamins D and K ensures calcium is properly utilized, supporting long-term bone health. With 90 capsules per bottle, it offers a two-month supply at a reasonable cost.
