Vitamin D and K with Sea-Iodine for Immune, Bone, Arterial and Thyroid Health, Non-GMO, Gluten-Free, 60 Capsules

Here's the content with adjusted language order, while maintaining the original semantics and a word count within 500:

Driven by an avalanche of favorable studies, record numbers of Americans now supplement with vitamin D. Obtaining adequate vitamin D from food sources is virtually impossible, requiring many aging individuals to take 5,000-8,000 IU daily. 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. Vitamin D facilitates calcium absorption into the bloodstream, playing an important role in maintaining bone density. However, the need for vitamin K to transport calcium from the bloodstream into the bone is less recognized. 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.

Are you getting enough vitamin D3? We've combined several nutrients that diets often lack, like vitamin D, which helps maintain a balanced immune system along with other benefits, from bone health to cognitive function. Vitamin D is necessary for bone health because, along with vitamin K, it gets calcium into your bones. Not only that, but we include multiple types of vitamin K in this formula: vitamin K1 as well as two types of vitamin K2.

There's one more nutrient some people may lack: iodine. Common in table salt (and missing from many healthy diets), iodine is used to make thyroid hormones. Your thyroid helps regulate your body's metabolism.

At Life Extension, we use only the finest raw ingredients with the purity and potency you deserve. The majority of our products are non-GMO, gluten-free, and manufactured in the USA—and a Certificate of Analysis is available for every one. We believe the answers to a healthier life are within reach, and that scientific research is the key to getting us there.
