Life Extension Vitamins D and K with Sea-Iodine – Bone, Brain, Thyroid & Arterial Support – Non-GMO, Once Daily, Gluten-Free – 60 Capsules

Maintaining optimal vitamin D levels helps support cognition, bone density and immune response. Vitamin K helps maintain your body’s calcium balance, which affects everything from your cardiovascular system to bone density. Iodine is essential for the production of thyroid hormones—but many people don’t get enough. Odds are your multivitamin has vitamin D in it—and probably vitamin K as well. But how much? Along with iodine, these two vitamins are among the most overlooked parts of a nutritional regimen. That’s because the traditional sources of vitamin D (sunshine), vitamin K (meat, cheese, leafy greens, and eggs) and iodine (seafood) just aren’t on everyone’s menu. So we made a convenient supplement that delivers all three nutrients in a single capsule. Your skin makes vitamin D from sunlight (and indoor tanning devices), but that’s not ideal. Vitamin D helps preserve youthful cognitive function, supports your bones and immune system and promotes endothelial function. Vitamin D can also help maintain blood pressure already in the normal range, which is good for your heart. Vitamin K helps maintain optimal calcium balance, which is good for your bones and arteries. But what does “calcium balance” mean? Basically, vitamin K helps inhibit calcification in the arteries and promotes calcium absorption into bones. By helping your body route calcium to where it should be, vitamin K promotes calcium balance. Iodine is essential—so much so that it has been added to table salt since the early 1920’s. But many people avoid salt. This means that many people unintentionally miss out on the benefits of iodine. That’s why we’ve included it in here. Iodine comes from seafood—in this case, it is derived from two distinct seaweed species. Vitamin D3 is known as the “sunshine” vitamin because your body produces it when exposed to sunlight. But because vitamin D is so important for your body, it’s best not to rely on sun exposure as your only source. Vitamin K comes from leafy greens, cheese and eggs—which many people avoid. The amount of vitamin K in these foods is also scant, especially in the case of vitamin K2. So in many cases, supplementing is more desirable. Your body needs iodine to produce thyroid hormones like triiodothyronine (T3) and thyroxine (T4). But because not everyone eats table salt or seafood (the prevalent food source of iodine), many people aren’t getting enough. We took three nutrients everyone needs, but that many of us don’t get enough of, and combined them into a single once-daily, non-GMO formula. Delivers 125 mcg (5000 IU) of vitamin D3 Contains 2100 mcg of vitamin K, including 1000 mcg of K1 and two forms of K2 (1100 mcg total) Also has 1000 mcg of iodine (derived from organic kelp and bladderwrack seaweed) Delivers 125 mcg (5000 IU) of vitamin D3 Contains 2100 mcg of vitamin K, including 1000 mcg of K1 and two forms of K2 (1100 mcg total) Also has 1000 mcg of iodine (derived from organic kelp and bladderwrack seaweed) An avalanche of favorable studies has resulted in record numbers of Americans supplementing with vitamin D. Since it is virtually impossible to obtain adequate vitamin D from food sources, supplementation with 5,000-8,000 IU daily is required by many aging individuals. Overlooked by almost everyone (except Life Extension members) is the critical importance of vitamin K. If one is concerned enough about their health to take higher dose vitamin D, it seems absurd to miss out on the benefits of vitamin K. For instance, vitamin D facilitates calcium absorption into the bloodstream and thus plays an important role in maintaining bone density. Less recognized is the need for vitamin K to transport calcium from the bloodstream into the bone. Vitamin K is also required by calcium-regulating proteins in the arteries. Together these two vitamins help maintain youthful calcium skeletal distribution while promoting vascular health.
