What is vitamin D3 + K2?

(D3 and phylloquinone or menaquinone)

D3 increases intestinal calcium absorption; K2 activates osteocalcin, a bone protein that binds calcium, and matrix Gla protein, which prevents calcium from depositing in arteries. Together, they direct dietary calcium to bone, not soft tissue. The combination is especially valuable for aging adults, women approaching menopause, and anyone with arterial calcification concerns.

What's in it

  • Vitamin D3Helps absorb calcium
  • K2Directs calcium to the bones

Synergistic

D3 and K2 work together for bone and vascular health

K2 comes in two forms: K2-MK7 (from fermented foods) and K2-MK4 (from animal products). Most supplement forms use K2-MK7, which has a longer half-life.

Is it right for you?

  • Who it's for

  • What sets it apart

  • Worth knowing before you start

    Never with warfarin: vitamin K cancels it.

What to expect

  • Better energy

    especially if you were deficient

  • Stronger bones

    D and K work synergistically over months

  • Reduced inflammation

    fish oil and Q10 support recovery

  • Improved endurance

How vitamins work

  1. Day 1

    Your physician reviews your diet, lifestyle, lab values (including vitamin D level), and goals. Discusses which vitamins fill gaps and how to time them with meals.

    1
  2. Week 1

    Start your daily vitamins with breakfast or as directed. Take fat-soluble vitamins (D, K, CoQ10, fish oil) with food to improve absorption.

    2
  3. Weeks 2-4

    Most people tolerate vitamins well. Some notice subtle energy shifts or better joint comfort. Keep a symptom log.

    3
  4. Month 2-3

    Your physician may check follow-up labs (vitamin D level, if supplementing D) to confirm optimal dosing.

    4
  5. Beyond

    Vitamins work best on a consistent daily schedule. Annual labs and check-ins ensure your regimen matches your current needs.

The science of essential vitamins

D3 + K2 studies show better bone density and lower arterial calcification compared to D3 alone in populations deficient in both.

K2 is an emerging nutrient; clinical trials are ongoing. Your physician assesses your calcium status and vascular risk to decide if D3 + K2 is right for you.

Important safety information and common side effects

Vitamins D, K, CoQ10, and fish oil are generally well tolerated at recommended doses. D3 at very high doses (over 10,000 IU daily long-term) can raise serum calcium; your physician sets your dose. K2 is safe; no upper limit is established. Q10 is safe; high doses may cause mild GI upset or insomnia. Fish oil can thin blood slightly at high doses; tell your physician if you take anticoagulants or antiplatelet drugs. Fish oil may cause burping or GI upset in some people. Stop and seek care for signs of hypercalcemia (nausea, vomiting, confusion) or unusual bleeding.

Frequently asked questions

How do I take Vitamin D3 / K2 Capsules?

Taken by mouth, twice a week. The starting prescription is 1 capsule each time. Your physician sets your own dose and it is printed on your label.

What exactly is in it?

Vitamin D3, K2.

How much arrives in each shipment?

9 capsules at the starting strength, shipped to your door from a licensed US pharmacy.

Why add K2 to D3?

D3 without adequate K2 can increase calcium absorption but doesn't guarantee it goes to bone rather than arteries. K2 activates the proteins that bind calcium to bone matrix and prevent arterial stiffening. For bone and heart health together, the combination is ideal.

Can I take all these vitamins together?

Yes. D, K, CoQ10, and fish oil are safe to take together. Take them all with food to improve absorption. Separate any other medications by 2-4 hours from fish oil if you are on blood thinners.

How do I know if I am deficient?

Vitamin D deficiency is easy to test; your physician can check your serum 25-hydroxyvitamin D level. K, Q10, and omega-3 deficiencies are harder to test precisely, but dietary assessment and symptoms guide supplementation.

Are vitamins from food better than supplements?

Ideally, you get vitamins from food. But modern diets often fall short. Supplements fill gaps. A varied diet plus targeted supplements usually works best.

How long until I notice a change?

Energy shifts may appear in weeks; bone and joint benefits take months to become obvious. Be patient and consistent; improvements build gradually.
