Frequently Asked Questions

Is it safe to take Vitamin D3 and K2 together?

Yes, taking my liquid Vitamin D3 with K2 is both safe and highly beneficial. Combining vitamin D3 and vitamin K helps your body absorb calcium effectively to ensure it is directed to your bones. This powerful duo works together to support bone strength, cardiovascular health, and overall wellness. Our liquid Vitamin D3/K2 formula blends seamlessly into smoothies and drinks, making it an effective way to maintain your D3 and K2 levels.

What is the optimal level of vitamin D?

Optimal levels of vitamin D have been hotly contested for decades, with “normal” being described by many physicians as anything above 30ng/dl. We recommend speaking to your qualified healthcare provider to find out what level is best for you based on your age, weight, and health history.

How can I find out my vitamin D levels?

If you’d like to have your vitamin D levels checked, all it requires is a simple and inexpensive blood test. Many doctors will order this test for you if you ask them to, and it is especially important to monitor your levels when you are taking higher amounts in an effort to raise your vitamin D to optimal levels. 

When is the best time of day to take Vitamin D3/K2? Should it be taken with or without food?

Vitamin D3/K2 can be taken at any time of the day, morning or evening. Vitamin D3/K2 should always be taken with meals if possible as both vitamin D3 and vitamin K2 are fat soluble, and taking the formula with a meal will greatly improve its absorption.
