Life Extension Vitamins D and K with Sea-Iodine

The Synergy of Vitamin D3 and K2

Vitamin D3 and vitamin K2 work together to support your body's calcium balance. Vitamin D3 helps increase calcium absorption from food, while vitamin K2 activates proteins that direct calcium to bones and teeth rather than soft tissues like arteries. This partnership helps maintain normal bone density, arterial flexibility, and immune function. Life Extension Vitamins D and K with Sea-Iodine also delivers vitamin K1 and iodine, offering additional support for normal blood clotting, bone metabolism, and thyroid health. Many people choose a combined D3 and K2 supplement to address common shortfalls, particularly if their diet is low in these nutrients.

Why Iodine Matters

Iodine is a trace mineral essential for the production of thyroid hormones, which help regulate metabolism. Modern diets often lack sufficient iodine, especially if iodised salt is avoided. By adding iodine from a natural sea source, this formula helps you meet your daily needs, supporting normal thyroid function and overall metabolic health.

What to Look For in a D3 + K2 Supplement

When choosing a vitamin D3 and K2 supplement, consider the type of K2, additional nutrients, and the manufacturer's quality standards. This formula provides a balanced combination of vitamin D3, K1, K2 (as MK-4 and MK-7), and sea-sourced iodine. The inclusion of both MK-4 (rapid activity) and MK-7 (sustained release) ensures effective support. Life Extension uses research-backed ingredients and doses, and each batch is tested with a Certificate of Analyse available. The product is non-GMO, gluten-free, and made in the USA from globally sourced ingredients.

Important Considerations

If you take medication, particularly blood thinners like warfarin, consult your doctor before adding vitamin K supplements, as it may interact with anticoagulant therapy. Take this supplement with a meal containing fat to aid absorption of the fat-soluble vitamins D and K. The recommended serving is one capsule daily with food, or as advised by a health care professional. These amounts support general wellness. Always consult your GP before starting any new supplement, especially if you are pregnant, breastfeeding, or have a medical condition. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
