Frequently Asked Questions
Why take D3 with K2?
K2 directs calcium to bones instead of arteries. Without K2, high D3 can cause arterial calcification.
How much vitamin D3?
2000-5000 IU daily. Get blood tested - aim for 40-60 ng/mL.
Should D3 be taken with fat?
Yes - D3 is fat-soluble. Coconut oil improves absorption.
What form of K2 is best?
MK-7 has a longer half-life than MK-4, providing more sustained activity.
