How does it work? keyboard_arrow_down
add remove

Most vitamin D3 supplements use doses that are too low (1,000-2,000 IU), not enough to make up for a real deficiency. Our formula provides 10,000 IU of D3, the dose recommended by research to raise blood levels effectively, combined with 200 µg of vitamin K2 (MK-7).

Why is K2 essential?
D3 increases calcium absorption. Without K2, that calcium can end up in the arteries instead of the bones. K2 acts like a "road sign": it directs calcium where it needs to go, towards the bones and teeth, keeping it away from the arteries and soft tissues.

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

Frequently asked questions keyboard_arrow_down
add remove

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

Studies show that most adults with a deficiency need 5,000-10,000 IU a day to restore an optimal blood level (125-200 nmol/L). Traditional 1,000 or 2,000 IU supplements are often not enough to have a real effect. If in doubt, ask your doctor and have your vitamin D level checked with a simple blood test.

Why should K2 be combined with D3?

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

Which form of K2 do you use?

We use MK-7 (menaquinone-7). It's the form of K2 most readily used by the body (the highest bioavailability) and the one that stays active in the body the longest (up to 72 hours, compared with just a few hours for the MK-4 form).

Can I take it alongside 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 softgels. At one softgel a day, that's a full 6-month course.

When will I notice a difference?

Most users notice an improvement in energy and mood within 2-4 weeks. For bone density the effects take longer: around 3-6 months of regular use. We recommend testing your vitamin D level before you start and again after 3 months, to track your progress.

The vitamin that 80% of over-60s are lacking (without knowing it)

After the age of 50, your skin makes 50-75% less vitamin D from sunlight than when you were 30. Spending time outdoors is no longer enough: your body, physically, can no longer turn the sun's rays into vitamin D the way it once did.

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

Our D3+K2 formula provides 10,000 IU per softgel, the dose shown by research to restore an optimal blood level. We've combined it with 200 µg of K2 (MK-7), so that calcium is sent to your bones and not to your arteries.

  • Just one softgel a day.
  • Made with coconut oil for maximum absorption.

Why vitamin K2 is far more crucial than you think

Most vitamin D3 supplements forget K2. And that's a real problem.

Vitamin D3 helps the gut absorb calcium: that's its main job. But without K2, your body doesn't know where to store that calcium. The result? It can build up in the arteries, kidneys or soft tissues instead of strengthening your bones.

K2 activates the proteins that send calcium where it needs to go: into the bones and teeth, and above all away from the arteries.

Think of D3 as the delivery van and K2 as the driver. Without a driver, the delivery ends up at the wrong address.

Our formula uses MK-7, the form of K2 most readily used by the body (the highest bioavailability). It stays active in your body for up to 72 hours, unlike the MK-4 form, which disappears after a few hours. A single softgel gives you the D3 + K2 combination at clinically studied doses. No more buying them separately.

One softgel. Four pillars of your health.

The vitamin D3 and K2 duo doesn't work on just one front. It works on several of your body's vital systems at the same time:

  • 🦴 Bone density: D3 helps calcium absorption and K2 directs it to the 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 people with an optimal vitamin D level fall ill less often and recover faster.

  • ❤️ Cardiovascular health: K2 prevents calcification of the arteries by stopping calcium from settling on the vessel walls. For those already takingaged garlic extract for blood pressure, D3+K2 offers complementary support through a different mechanism of action.

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

Riccardo T.
Richard T., 63 Verified purchase

My doctor told me my vitamin D level was 45: dangerously low. After 3 months on this product my levels were back up to 155. My energy is a different story altogether. I used to crash every day around 2pm; now I stay active until the evening.

Margherita D.
Margaret D., 58 Verified purchase

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

Davide 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's combined and the dose is genuinely clinical: 10,000 IU, not the useless 1,000 IU that almost every brand sells. My defences in winter have clearly improved. I haven't had a single cold since I started. Simple, one softgel, done.

Susanna K.
Susan K., 59 Verified purchase

I started because I'd read that K2 stops calcium from settling in the arteries. I was already keeping an eye on my blood pressure, so adding it felt like the right thing for my heart. After 4 months my energy has gone up and my mood is genuinely better: I wasn't expecting that. My daughter noticed before I did.

Tiziano B.
Tim B., 61 Verified purchase

I was sceptical about yet another supplement, but a pharmacist friend of mine told me that most people over 50 are deficient in vitamin D without knowing it. I had the tests: he was right, I was at 47. I started on this product and within a month I noticed less joint stiffness in the morning and better sleep. The 180-softgel size is brilliant: I hate having to reorder every month.

Guglielmo P.
William P., 69 Verified purchase

My doctor tested my vitamin D: I was at 55. He told me to take a supplement, without recommending a specific one. I did my own research and found that most D3 supplements are underdosed and contain no K2. This one has the right dose of both. Three months later my levels are at 145 and I feel sharper, I sleep better and I have more energy on my morning walks.
