Frequently Asked Questions
Why combine Vitamin D3 with K2?
D3 helps the body absorb calcium; K2 (especially MK4/MK7) helps direct calcium into bone and away from soft tissues and arteries, supporting bone density and cardiovascular health when used together.
Which K2 form is better, MK4 or MK7?
MK-7 has a longer half-life and supports once-daily dosing, while MK-4 is often given at higher microgram doses in some clinical bone protocols. Many premium products include both to cover different mechanisms.
What dose of D3 + K2 should I take?
For routine maintenance many people use 1,000–5,000 IU D3 daily plus 50–200 mcg MK-7 or higher MK-4 doses depending on the product. If you suspect deficiency, higher or weekly therapeutic doses exist but should be used under a healthcare professional with 25(OH)D monitoring.
