When to take Vitamin K2
Take Vitamin K2 with a fat-containing meal, typically alongside Vitamin D3. K2 (MK-7) directs calcium toward bone and away from arteries, complementing D3's calcium-absorption role. A single 90–180mcg dose covers most adults.

Why timing matters
K2's effect is systemic and long-lived (MK-7 half-life is ~3 days), so daily timing slot is less critical than consistency.
Morning vs. night
Either; most pair it with D3 at breakfast.
Why with food
Fat-soluble; absorption depends on dietary fat.

FAQ
MK-4 vs MK-7?
MK-7 has a far longer half-life and is preferred for daily dosing. MK-4 requires multiple doses per day.
With Vitamin D?
Yes. K2 directs the calcium that D3 helps absorb into bone, a widely recommended pairing.
On a blood thinner?
Talk to your clinician first. Vitamin K can interact with warfarin.
