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.
As a dietary supplement take 1mL (1 dropper) per day with or without food. One dropper per day is plenty and we do not recommend exceeding it unless directed to do so by your physician. The Vitamin D3 + K2 solution uses MCT Oil as a base and so has plenty of fat for proper absorption but it can be taken with food if you prefer.
Vitamin D supplements are well tolerated and side effects are rare when it is taken at normal dosages. Side effects associated with taking too much Vitamin D include fatigue, drowsiness, headaches, nausea, dry mouth, or a metallic taste. If you experience any of these side effects we recommend lowering the dose taken or ceasing use entirely.
In rare cases taking Vitamin D supplements alone, especially at high doses, can cause short term hypercalcemia. Taking Vitamin K2 along with the vitamin D supplement prevents this so we have included 200 mcg of trans-K2 in this supplement.
Vitamin D3 + K2 Liquid Drops - $ 19.95 (5000 IU D3, 200 mcg K2 / mL - 30 servings)
