How does it work? keyboard_arrow_down

Most Vitamin D3 supplements use dosages that are too low (1,000-2,000 IU), insufficient to make up for a real deficiency. Our formula provides 10,000 IU of D3, the dosage recommended by research to effectively raise blood levels, combined with 200 mcg of Vitamin K2 (MK-7).

Why is K2 essential?
D3 increases calcium absorption. Without K2, this calcium can deposit in your arteries instead of your bones. K2 acts like a "traffic signal": it directs the calcium where it needs to go, toward your bones and teeth, keeping it away from your arteries and soft tissues.

Maximum absorption:
Since it is fat-soluble, Vitamin D3 needs fats to be absorbed properly. Our formula is enriched with coconut oil to ensure optimal absorption. Just one softgel a day with a meal. That's it.

Why 10,000 IU? Isn't that too much?

Studies show that most adults with a deficiency need 5,000 to 10,000 IU a day to restore optimal blood levels (50 to 80 ng/mL). Traditional supplements with 1,000 or 2,000 IU are often not enough to achieve a real effect. If in doubt, ask your doctor and have your vitamin D levels checked with a simple blood test.

Why should K2 be combined with D3?

D3 promotes calcium absorption in the gut. K2, in turn, activates the proteins that direct this calcium to your bones and teeth, and not to your arteries, kidneys, or soft tissues. Without K2, excess calcium can build up where it shouldn't. They work as a team.

What form of K2 do you use?

We use MK-7 (menaquinone-7). It is the form of K2 best usable absorbed by the body (the highest bioavailability) and the one that stays active the longest in your system (up to 72 hours, compared to just a few hours for the MK-4 form).

Can I take it with my blood pressure supplement?

Yes. The D3+K2 complex has no known interactions with Aged Garlic Extract, nattokinase, magnesium, or common blood pressure medications. Many of our customers add it to their daily routine alongside Aged Garlic Extract.

How long does one pack last?

The pack contains 180 capsules. At one capsule a day, this equals a full 6-month supply.

When will I see a difference?

Most users notice an improvement in energy and mood within 2 to 4 weeks. For bone density, the effects take a little longer: about 3 to 6 months of regular use. We recommend testing your vitamin D levels before starting and then again after 3 months to track your progress.

The vitamin that 80% of people over 60 are missing (without even knowing it)

After age 50, your skin produces from sunlight 50 to 75% less vitamin D compared to when you were 30. Spending time outdoors is no longer enough: your body physically cannot convert sunlight into vitamin D like it used to.

A vitamin D deficiency is directly linked to fragile bones, a weakened immune system, a lack of energy and a higher cardiovascular risk. The majority of adults over 50 are deficient without even realizing it.

Our D3+K2 formula features provides 10,000 IU per capsule, the dosage proven by research to restore optimal blood levels. We combined it with 200 mcg of K2 (MK-7), so that calcium is directed to your bones and not your arteries.

  • Just one capsule a day.
  • Formulated with coconut oil for maximum absorption.

Why Vitamin K2 is much more crucial than you think

Most Vitamin D3 supplements forget about K2. And that is a real problem.

Vitamin D3 promotes calcium absorption in the gut: that is its main job. But without K2, your body does not know where to store this calcium. The result? It can build up in your arteries, kidneys or soft tissues, instead of strengthening your bones.

K2 activates the proteins that direct calcium where it needs to go: into your bones and teeth, and most importantly away from your arteries.

Think of D3 as the delivery truck and K2 as the driver. Without a driver, the delivery goes to the wrong address.

Our formula uses MK-7, the most usable form of K2 for your body (the highest bioavailability). It stays active in your system for up to 72 hours, unlike the MK-4 form which disappears after just a few hours. A single capsule gives you the D3 + K2 combination in clinically studied dosages. You no longer have to buy them separately.

One capsule. Four pillars of your health.

The Vitamin D3 and K2 duo does not just work on one front. It works simultaneously on multiple vital systems in your body:

  • 🦴 Bone density: D3 promotes calcium absorption and K2 directs it to your bone structure. Together they reduce the risk of fractures and preserve the strength of your bones, a critical point after 50.

  • 🛡️ Immune system: D3 regulates the immune response to help your body fight infections while limiting excessive inflammation. Studies show that those with an optimal Vitamin D level get sick less often and recover faster.

  • ❤️ Cardiovascular health: K2 prevents arterial calcification by stopping calcium from attaching to blood vessel walls. For those already usingAged Garlic Extract for blood pressure, D3+K2 offers complementary support through a different mechanism of action.

  • ⚡ Mood and energy: D3 promotes the production of serotonin (the feel-good hormone). A deficiency is often linked to chronic fatigue and poorer sleep quality. Most users feel an energy boost within 2 to 4 weeks of correcting the deficiency.

My doctor told me my Vitamin D level was at 18: dangerously low. After 3 months on this product my levels went back up to 62. My energy is on a whole other level. I used to crash every day around 2 PM, but now I stay active until the evening.

Margaret D., 58 Verified Purchase

I bought this for my husband after his doctor recommended D3 and K2 for bone density. He has been taking it for 4 months. His last DEXA scan showed an improvement for the first time in years. We both started taking it. The 6-month supply really offers excellent value for money.

David H.
David H., 71 Verified Purchase

I used to take D3 and K2 separately from two different brands. I switched to this product because it is combined and the dosage is truly clinical: 10,000 IU, not the useless 1,000 IU that almost all brands sell. My winter defenses have improved significantly. I have not had a cold since I started. Simple, one capsule, done.

Susan K.
Susan K., 59 Verified Purchase

I started because I read that K2 prevents calcium from depositing in the arteries. I was already keeping an eye on my blood pressure, so adding this seemed like the right thing for my heart. After 4 months my energy has increased and my mood is genuinely better: I did not expect that. My daughter noticed it before I did.

Thomas B.
Thomas B., 61 Verified Purchase

I was skeptical about another dietary supplement, but a pharmacist friend told me that most people over 50 have a vitamin D deficiency without knowing it. I got tested: he was right, I was at 19. I started with this product and within a month I noticed less joint stiffness in the morning and better sleep. The 180-capsule pack is brilliant: I hate having to reorder every month.

George P.
George P., 69 Verified Purchase

My doctor tested my vitamin D: I was at 22. He told me to take a dietary supplement, without recommending a specific one. I did my research and found out that most D3 supplements are underdosed and lack K2. This one has the right dose of both. Three months later my levels are at 58 and I feel sharper, I sleep better and I have more energy on my morning walks.
