★★★★★ "I won't go back to high street supplements. The difference in quality is something you can actually feel." Susie
This capsule provides vitamin D3 with vitamin K2 as menaquinone 7. The two are most often taken together because both act on calcium.
Vitamin D supports the immune system, muscle function and the absorption of calcium, and vitamin K contributes to normal bones and normal blood clotting. Together they cover how calcium is taken up and where it goes.
Each capsule provides a high dose of D3 with K2 and nothing else apart from the vegetable shell. It is often chosen by people who have tested low in vitamin D and want one capsule a day.
| Each capsule contains: | %NRV* | |
|---|---|---|
| Vitamin D3 (2500 IU) | 62.5 mcg | 1250% |
| Vitamin K2 | 200 mcg | 267% |

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.
