Vitamin D is a fat-soluble essential vitamin synthesized by the skin when it is exposed to direct sunlight. Vitamin D plays a key role in numerous bodily processes including mood, immune system health, and bone health. While those who get plenty of sun likely do not need to supplement Vitamin D those who work indoors or don’t spend much time outside are likely to be deficient and can benefit from supplementing. Vitamin K is another of the essential fat-soluble vitamins and supports proper cardiovascular and bone health. K2 should always be supplemented with Vitamin D3 as high-dose supplementation of D3 alone can cause short-term hypercalcemia in some people. Our Vitamin D3 + K2 supplement includes the all-trans version of K2 (K2 Vital), which is much more effective than the cheaper cis-K2 variety and uses an MCT oil base providing plenty of fat for proper absorption so it is not necessary to take this product with food.

Quick shipping and great product. I’ll definitely buy again. \nI haven’t noticed a change yet as it’s too soon
Great for adding to coffee, water, or tea. Tasteless. Good source of vitamins.
Easy to use! Bought in Arizona and it delivered EXTREMELY HOT and the glass was almost burning! I do like it came in a glass box but either order it to the store or when it cools off outside because I had to order another one since getting that hot defeats the benefits! Other than that the dropper is easy to use and I feel more alert!
This is a great product but alot cheaper on amazon like $10 cheaper which is a huge difference!
i love the convenience of having a dropper rather than a pill for sure! i only take half a dropper every day with my calcium. easy peasy.
