- Immune function — vitamin D contributes to the normal function of the immune system
- Muscle function — vitamin D contributes to the maintenance of normal muscle function
- Normal blood clotting — vitamin K contributes to normal blood clotting
- One-a-day softgel — in an MCT (medium-chain triglyceride) oil base, as vitamins D and K are fat-soluble

Frequently asked questions
Q: Why combine vitamin D3 with K2?
A: Both vitamins contribute to the maintenance of normal bones, and vitamin D additionally contributes to normal calcium absorption and utilisation, so the two are commonly taken together in one capsule.
Q: Is 4000 IU a high dose?
A: 4000 IU (100 µg) is the level the NHS notes as the upper amount unlikely to cause harm for most adults when taken daily. Do not combine with other vitamin D supplements, and ask your pharmacist if you are unsure whether this strength is right for you.
Q: Can I take it with blood-thinning medication?
A: Vitamin K can interact with anticoagulant medicines such as warfarin. Speak to your GP or pharmacist before taking any vitamin K-containing supplement if you are on anticoagulants.
Q: Is it suitable for vegetarians?
A: No — the softgel shell contains bovine gelatine.
