Vitamin K2 Supplements in the UK
Vitamin K contributes to the maintenance of normal bones and to normal blood clotting. K2 is the form usually sold as MK-4 or MK-7, and this range also includes popular combinations with vitamin D3 from Carlson, Sports Research and Micro Ingredients.
Buying guide and FAQs
What to compare
Check whether a product contains MK-7 or MK-4 and how many micrograms it provides. With D3 + K2, check the vitamin D strength as well, because many imported products are far above the NHS 10 microgram daily recommendation.
Should I avoid K2 if I take warfarin?
Vitamin K can stop warfarin working properly. Do not take it unless your doctor or anticoagulant clinic has agreed.
How much vitamin D is too much?
The NHS advises adults not to take more than 100 micrograms (4,000 IU) of vitamin D a day unless a doctor recommends it.
