Why I made this

“My Vitamin D3/K2 liquid formula is essential for calcium absorption and bone health. Together, these two vitamins help maintain appropriate calcium skeletal distribution. Calcium is critical for optimal bone density as well as normal growth."†

Frequently Asked Questions

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.

Is Dr. Myers’ Vitamin D3/K2 Liquid safe for pregnant women and breastfeeding mothers?

Vitamin D3/K2 is safe to take while pregnant or nursing when used as directed, provided you have spoken to your physician first to ensure that you are not taking any prescriptions that may be contraindicated (especially blood thinners), or should not take it for any other reason. Keep in mind it is important to monitor blood levels when taking vitamin D longterm.

    I take D3/K2 liquid every day for the past year. It is convenient and I don’t have to swallow a large capsule.
