High-Dose Vitamin D3 works to support upper respiratory, bone, and skin health


Vitamin D3 is the naturally occurring form of the D vitamin and it is produced by the human body when skin makes contact with direct sunlight. The health benefits of Vitamin D are known to be extremely important to overall health.

Studies have shown that Vitamin D regulates the absorption of calcium and phosphorus, as well as facilitates normal immune system function. 

We recommend that you ask your healthcare provider about your specific vitamin D needs.

    Great product and lasts me a year! It was hard to find a brand I trusted that offers this much Vitamin D in one pill. I like taking the 50,000 IU once per week because I’m just not as consistent if I have to take a pill every day. Thanks for offering this!

    While this was my first time ordering online I first got it about two years ago following a office visit with Dr Clarke.
