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 D3 helps your body absorb calcium from your diet, while Vitamin K2 activates specialised proteins, including osteocalcin and Matrix Gla Protein (MGP), that help your body use calcium where it is needed most.

This unique partnership helps support healthy bones, teeth and normal calcium metabolism in a way that Vitamin D3 alone cannot.

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 belive Vitamin D3 is one of the most important supplements in helathy ageing. It is involved in so many important functions in your body. Its deficiency is one of the most common nutritional deficiencies worldwide, yet many supplements overlook the importance of combining it with Vitamin K2.

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 capsule 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.

You can begin taking Ki Vitamin D3 + K2 immediately.

Many people are low in Vitamin D without realising it, particularly during autumn and winter or if they spend little time outdoors.

Daily supplementation helps maintain healthy Vitamin D levels throughout the year.

Vitamin D3 and Vitamin K2 are among the most important nutrients for lifelong health and healthy ageing.

Vitamin D3 is unique because it acts as a precursor hormone rather than a traditional vitamin. Almost every cell in the body contains Vitamin D receptors, highlighting its importance far beyond bone health. Scientists continue to explore its wider role in areas such as healthy ageing, circadian biology and hormonal signalling.

Together, Vitamin D3 and Vitamin K2 contribute to:

• Normal immune function
  
• Normal absorption and utilisation of calcium and phosphorus
  
• Normal blood calcium levels
  
• The maintenance of normal bones and teeth
  
• Normal muscle function
  
• The process of normal cell division
  

Vitamin K2 complements Vitamin D3 by activating specialised proteins that help your body use calcium effectively, supporting healthy bones and teeth while helping maintain normal calcium distribution throughout the body.

Together, they form one of the body's most important nutritional partnerships.

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 capsule daily with a meal containing healthy fats, such as olive oil, avocado, nuts, seeds or oily fish.

Because Vitamin D is fat-soluble, taking it with food helps maximise absorption.

For best results, take it consistently at the same time each day as part of your daily wellness routine.

Yes.

Ki Vitamin D3 + K2 pairs well with most supplements, including Ki Collagen, Magnesium, Omega-3, NMN and Ashwagandha.

If you are taking prescription medication, particularly blood-thinning medication such as warfarin, please consult your healthcare professional before taking Vitamin K2.

Yes. Ki Vitamin D3 + K2 is designed for daily use and is most effective when taken consistently as part of your long-term healthy ageing routine.

You do want to check your vitamin D3 levels every 3-6 months if they were very low. If you were under 30ng/ml it may be a good idea to double your dossage of Vitamin D3/K2 for 1-2 months and then test your blood levels and ajust.

Optimum range for longevity and thriving health is 60-80ng/ml.

Absolutely.
