How much vitamin K?

The Recommended Dietary Allowance (RDA) for men is 120mcg and for women 90mcg. 


Too much v.s. too little

Too much vitamin K can be harmful for people with kidney disease who are on dialysis. High doses of vitamin K taken by people with liver disease can actually cause clotting problems. People with reduced bile secretion might need to take additional bile salts to help with vitamin K absorption. If taking an anticoagulant, it is important to keep the vitamin K intake consistent. 

Do not take vitamin K together with warfarin since they interact with each other! 

Vitamin K deficiency is rare, however not taking in the recommended amount may lead to clotting problems, weaker bones and there is a potential risk for developing heart disease.
