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 5,000-10,000 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.
Vitamin K can be found in small amounts in the diet, but obtaining the desired higher potencies requires supplementation. Many Life Extension members obtain optimal potencies of long-acting vitamin K in the Super Booster or Super K formulations. An increasing number of new members, however, are asking for high-potency vitamin D— but are not taking any supplemental vitamin K.
To directly address this problem, Life Extension has put together a formula called Vitamins D and K with Sea-Iodine & trade;. Like vitamins D and K, few Americans obtain optimal amounts of iodine. As people seek to limit their salt intake, this deficit is exacerbated since iodized salt is the principal source of this mineral in many diets. We expect the issue of iodine insufficiency to receive more media attention as new studies uncover the problems this creates. Sea-Iodine & trade; is included in this formula to provide iodine without the harmful effects of sodium.

iHerb Customer Reviews
I was taking 4000 IU of Vit D, 100 mcg of Vit K (7), and 1000 mcg of Iodine for the past few years. These capsules are great because now all 3 are combined into 1 so it's easier for me to take...and I get even more beneficial levels of the D and K with this supplement. Great product and without it, I would barely have any of these 3 nutrients in my body which would be a disaster over time. Research each of the 3 and you will see why. The only thing that could make this supplement even better would be to add ubiquinol to it! Then I would only have to take one more supplement daily in addition to this one...fish oil.
I love the combo in this product. These are a must for those who want to have strong and healthy teeth!

Will never order from iherb again.I was charged $19.77 dollars extra for shipping when my product arrived at the door,and $8.50 for other shipping charges.My shipping fees were more then the product itself.Very disappointed.When i called customer service they said i asked for dhl shipping so it had to go thru customs.No i didn't ask for dhl shipping .It didn't state that on my final order when i checked out.

This is a convenient way of taking the vitamins D and K which need to be taken synergistically
