    Why combine D3 with K2?Vitamin D contributes to the normal absorption and utilisation of calcium. Vitamin K contributes to the maintenance of normal bones. That is why they belong together.

NAORI Ki Vitamin D3 K2 unites D3 and K2 in a refined formulation that honours both science and simplicity. Known as the “sunlight vitamin,” D3 supports many of the body’s natural functions, while K2 is essential for calcium absorption with quiet precision.

Together, they form a perfect synergy for balance, strength, and vitality.

Vitamin D3 contributes to the maintenance of normal bones, muscles, and immune function, while Vitamin K2 helps direct calcium to where it’s needed most - the bones and away from soft tissues such as arteries.

This intelligent partnership helps the body use calcium efficiently, creating harmony between bone and cardiovascular health. A modern expression of nature’s own design.

In today’s fast-paced world, many of us spend long hours indoors and get little natural sunlight yet Vitamin D3 is essential for bone strength, muscle function, and immune balance.

Vitamin K2 works in quiet synergy, guiding calcium to where it belongs the bones and away from soft tissues.

Together, D3 and K2 form a natural alliance that helps the body use calcium intelligently, creating harmony between strength, structure, and vitality.

Our Ki Vitamin D3 + K2 is natural, pure, and potent, formulated for optimal absorption and balance. Each tablet delivers precisely dosed nutrients in their most bioavailable forms, crafted to support everyday resilience with the elegance and integrity that define NAORI.

Clean science. Quiet strength. Vitality refined.

One Tablet. With Something Fatty.

Take one tablet daily with a meal that contains some fat. Olive oil, avocado, nuts, seeds or oily fish will all do it. Vitamin D is fat soluble, which means your body absorbs far more of it alongside fat than it does on an empty stomach.

It is the easiest thing on this page to get right, and the easiest to get wrong.

Modern life often keeps us indoors and studies show that many people today have insufficient levels of Vitamin D. From young adults to the elderly, maintaining optimal Vitamin D levels is essential for bone strength, immune balance, and overall immunity and vitality.

Ki Vitamin D3 K2 is your daily ally in graceful ageing, a pure, potent blend designed to support the body’s natural resilience and inner radiance at every stage of life.

One Helps You Absorb Calcium. The Other Puts It To Work.

Vitamin D helps your body absorb and use calcium. Vitamin K2 activates the proteins that help bind calcium into bone. They are sold together because they work on the same system from different ends, and taking one without the other is doing half the job.

One tablet. Both, at the strength they are meant to be.

Half the Year, Britain Cannot Make Any.

Your skin makes vitamin D from sunlight. At this latitude, for roughly half the year, the sun is not strong enough for that to happen at all, however much time you spend outside. That is why UK guidance suggests considering a supplement through the autumn and winter, and it is why this is the least controversial thing in the whole range.

Start before the clocks change and you will not notice the gap.

Why We Stop at 4,000 IU.

4,000 IU is the upper daily amount recommended for adults in the UK, and one tablet contains exactly that. It is a strong dose and it is deliberately not a stronger one. If you have had a blood test and you think you need more, that is a conversation with your doctor rather than something a supplement website should be telling you.

One tablet a day. Do not exceed it.

Frequently Asked Questions

Most Vitamin D supplements contain only Vitamin D3.

We chose to combine premium Vitamin D3 with Vitamin K2 as MK-7, the most bioavailable and longest-lasting form of Vitamin K2.

Vitamin D contributes to the normal absorption and utilisation of calcium. Vitamin K contributes to the maintenance of normal bones. That is why they belong together in the same tablet.

Like every NAORI supplement, Ki Vitamin D3 + K2 is manufactured in the United Kingdom using premium-quality, 100% natural ingredients, contains no unnecessary fillers, artificial colours or preservatives, and reflects our commitment to quality, purity, transparency and results.

At NAORI, we believe healthy ageing begins by providing the body with the essential nutrients it needs to thrive.

We believe Vitamin D3 is an important nutrient for maintaining normal body functions. It contributes to the maintenance of normal bones, normal muscle function and the normal function of the immune system.

We created Ki Vitamin D3 + K2 because we wanted a formula that reflected both science and nature: pure, effective and made without compromise.

Like every NAORI product, it is a supplement we created first for our own families and our clinical clients, using only ingredients we trust, complete transparency and an unwavering commitment to quality.

Ki Vitamin D3 + K2 combines two essential nutrients that work together to support your health.

Each tablet provides:

  • Vitamin D3 (the active form naturally produced by your skin from sunlight)
  • Vitamin K2 (MK-7), which helps direct calcium to your bones and teeth, where it belongs.

Together, they support healthy bones, teeth, muscles, immune function and cardiovascular health.

Our Vitamin D3 is naturally sourced from lanolin, while our premium MK-7 Vitamin K2 is produced through natural fermentation for excellent purity and stability.

Vitamin D and vitamin K contribute to several normal functions in the body.

Vitamin D contributes to the normal function of the immune system, the maintenance of normal bones, teeth and muscle function, and the normal absorption and utilisation of calcium and phosphorus.

Vitamin K contributes to the maintenance of normal bones and normal blood clotting.

Together, these nutrients provide complementary support for normal calcium absorption and the maintenance of normal bones.

This varies from person to person and depends on your current Vitamin D3 levels.

Some people notice improvements in energy, mood and general wellbeing within a couple of weeks, while others may take longer.

The greatest benefits come from taking it consistently over the long term.

Take one tablet daily with a meal that contains some fat. Olive oil, avocado, nuts, seeds or oily fish will all do it. Vitamin D is fat soluble, which means your body absorbs far more of it alongside fat than it does on an empty stomach.
