Life Extension Vitamins D and K with Sea-Iodine, vitamin D3, vitamin K1 and K2, iodine, supports immune, bone, arterial and thyroid health, non-GMO, gluten-free, 60 capsules

Recent studies have led to a surge in Americans supplementing with vitamin D, particularly older adults who may need 5,000-8,000 IU daily due to dietary inadequacies. However, the importance of vitamin K is often overlooked. Vitamin D aids calcium absorption for bone density, while vitamin K is essential for transporting calcium into bones and regulating calcium in arteries. Together, they promote skeletal health and vascular function. Life Extension emphasizes the need for both vitamins and includes various forms of vitamin K in their supplements, which also support immune and thyroid health, using high-quality, non-GMO ingredients.
