Vitamin D3 with K2

D3 raises calcium absorption. K2 directs that calcium into bone rather than arterial tissue. Taking D3 alone at high doses without K2 is a common mistake.

No charge until a clinician approves your plan.

Vitamin D insufficiency affects an estimated 40% of US adults.

What is in it

5,000 IU vitamin D3 with 100 mcg vitamin K2 as MK-7.

How to take it

  • Take one capsule daily with your largest meal.
  • Both vitamins are fat soluble, so food matters.
  • Morning dosing suits most people.
  • Recheck your level after twelve weeks.

Why clinicians prescribe it

Calcium goes where it should

K2 activates the proteins that direct calcium into bone.

Dosed from your blood work

We measure 25-OH vitamin D before recommending a dose.

One capsule

Both nutrients in a single daily capsule.

Common questions

It is a standard repletion dose for a documented insufficiency. If your level is already comfortable, your clinician will move you to a lower maintenance dose.

Important safety information

Do not exceed the recommended dose without a recent lab result. Talk to your clinician first if you take warfarin, because K2 interacts with it.
