Product Information

Isotonix® Vitamin D with K2

Makers of bone health supplements boast about the amount of vitamin D in their products. But only Isotonix delivers a bone health supplement that contains vitamin D with K2 - making it the best supplement to help maintain your bone health.

Isotonix Vitamin D with K2 contains vitamin D3, the metabolically active form of vitamin D, along with vitamin K2, a form of vitamin K which supports vascular health and calcium utilization. Vitamin K is included in Isotonix Vitamin D with K2 because of its unique partnership with vitamin D. Vitamins K and D work together to support calcium absorption and utilization. Vitamin K supports the normal delivery of calcium to the bones and promotes healthy arteries.

Despite the fact that there are many vitamin D and bone health supplements to choose from, Isotonix Vitamin D with K2 proves that all supplements are not created equal.

    I take it first thing in the mornings that I do not plan to be in the sun. I live in an area that is cloudy for much of the winter & and often in the spring and fall, too.


    Re: "Wasted 1/4 of Product"

    Comments about Isotonix® Vitamin D with K2:

    Maria, I hope that you read this! The "Cap" that you measure the powder into is NOT the cap that you fill with water! Your product should have come with an "overcap" that is used to measure the right amound of water (2 ounces) for every bottlecap of powder. THAT cap is the one that is right on the bottle. If you use them correctly, you should not have water getting into the bottle. That having been said, if you live in a humid environment, you can actually just refrigerate the bottle to make sure that it stays fresh and dry.


    Wasted 1/4 of Product

    Comments about Isotonix® Vitamin D with K2:

    Somehow water got inside the bottle and wasted the 1/4 of remaining powder. I think a different mechanism is needed, since the bottle top is used to administer the product with water. I'm going to try again and use without the bottle top to see if it makes a difference.
