Frequently asked questions
What does vitamin D do?
Under the EU/UK Register of Health Claims, vitamin D contributes to the normal function of the immune system, to the maintenance of normal bones, teeth and muscle function, and to the normal absorption of calcium. Each capsule provides 5000IU of vitamin D3.
Why is vitamin K2 included with vitamin D3?
Vitamin K contributes to the maintenance of normal bones, which is why it is combined here with vitamin D3. This product provides 100ug of vitamin K2 as menaquinone-7 (MK-7) per capsule.
Is 5000IU of vitamin D a high dose?
Yes, it is a higher-strength product. The NHS notes that taking up to 100 micrograms (4000IU) of vitamin D a day is unlikely to cause harm for most adults; 5000IU is above that level. If you are unsure whether this strength is right for you, or you take other vitamin D products, check with your pharmacist or GP.
Is it suitable for vegetarians?
Yes. The capsule shell is plant-based (hydroxypropyl methylcellulose) and the product is GMO-free, making it suitable for vegetarians.
Can I take it if I am on blood-thinning medication?
Vitamin K can interact with anticoagulant medicines such as warfarin. If you take a blood thinner, do not take a vitamin K supplement without first speaking to your GP or pharmacist.
