★★★★★ "I won't go back to high street supplements. The difference in quality is something you can actually feel." Susie
Vitamin D3 and K2 Capsules give you a high dose of vitamin D3 with vitamin K2, the pair that work together on calcium. Each capsule provides 2500 IU of D3 and 200mcg of K2 as MK-7, taken once a day with food. One pot holds 90 capsules, which is a 90 day supply.
Benefits of taking vitamin D3 and K2
Vitamin D helps your body absorb calcium, while vitamin K helps keep it in your bones and keeps blood clotting normally. Together they cover how calcium is taken up and where it goes, which is why the two are so often taken as a pair.
- Bones and teeth stay strong, because both vitamins act on calcium.
- Your immune system gets the vitamin D it relies on.
- Muscles keep working as they should.
- Blood clots normally, which is vitamin K's other job.
Who benefits
Vitamin D3 and K2 Capsules are most useful for:
- Adults who have tested low in vitamin D and want one capsule a day to bring it up.
- People who want to look after their bones and teeth, which both vitamins help maintain.
- Anyone taking calcium, because vitamin D helps absorb it and K2 helps decide where it goes.
- Those who want the long acting MK-7 form of K2, so one capsule a day covers the day.
For a lower amount you can adjust drop by drop, choose Vitamin D3 and K2 Oil.
What is in it
Each capsule provides 62.5mcg of vitamin D3, which is 2500 IU and 1250% of the daily reference value, with 200mcg of vitamin K2 as menaquinone 7, which is 267% of the daily reference value. There is nothing else in it apart from the vegetable capsule shell. D3 with MK-7 and cholecalciferol with menaquinone-7 are other names for the pair.
How to take it
Take one capsule a day with food. Vitamin D is fat soluble, so a meal that contains some fat improves absorption. Do not take more than one a day unless your practitioner advises it.
Diet and allergens
The capsules are suitable for vegetarians but not for vegans. They are free from gluten, dairy and nuts.
Quality
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
Common questions
Which forms of D3 and K2 are in these capsules?
The vitamin D is D3, cholecalciferol, the form your skin makes and the one that raises blood levels most reliably. Its partner is K2 as menaquinone 7, or MK-7, which stays in circulation far longer than MK-4, so one capsule a day covers the day.
How much vitamin D should I take a day?
Take one capsule a day, which gives you 2500 IU of vitamin D3 and 200mcg of K2. Higher amounts are for a practitioner to decide.
When is the best time to take vitamin D3 and K2?
You can take it at any time of day, with a meal that contains some fat. Having it with your largest meal makes it easy to remember.
Can I take it with other supplements?
Yes. It pairs well with Magnesium Bisglycinate (Glycinate) Capsules, because your body uses magnesium to regulate the active form of vitamin D.
Can I take too much vitamin D?
Yes, because vitamin D is fat soluble, so keep to one capsule a day unless your practitioner says otherwise. If you are unsure of your level, a blood test for 25(OH)D through your GP or a home testing service is the most reliable way to check.
Capsules or oil, which should I choose?
The capsules give you a fixed 2500 IU a day with K2, which suits people who have tested low and want one capsule a day. Vitamin D3 and K2 Oil gives you the same pair at a lower amount you can adjust drop by drop.

Frequently asked questions
Why take Vitamin D3 & K2?
Vitamin D3 & K2 supports bone health, immune function, and mood regulation.
How much vitamin D do I need?
Most adults benefit from 2000-4000 IU daily, depending on blood levels.
When should I take vitamin D?
Take with your largest meal containing fat for best absorption.
Can I take too much vitamin D?
Yes, vitamin D is fat-soluble. Get your levels tested and work with a practitioner to find your optimal dose.
Why is vitamin D paired with K2?
Vitamin D contributes to the normal absorption of calcium and the maintenance of normal bones, and vitamin K contributes to the maintenance of normal bones and normal blood clotting. The pairing covers both of those authorised roles in one capsule.
Which forms of D3 and K2 are in these capsules, and why do they matter?
The vitamin D is D3, cholecalciferol, the form the skin makes and the one that raises blood levels most reliably. The K2 is menaquinone-7, MK-7, the form of vitamin K that stays in circulation longest, so one daily dose covers the day; MK-4, the other common K2, clears within hours and has to be taken several times. This capsule gives a high D3 dose with 200 mcg of MK-7, which suits people who have tested low in vitamin D and want one capsule a day. For a lower adjustable dose of the same pair see the D3 and K2 oil.
Why capsules rather than tablets?
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
