If you add any type of vitamin K supplement in your diet then it may lead to toxicity.

Vitamin K can interact with some common medicines such as :

1. Blood-thinners –

Blood thinners simply work by diminishing or deferring the coagulating capacity of vitamin K. Thus, sudden increase or decrease in the intake of vitamin K can interfere with such medicines. Thus, maintain the ideal and consistent intake of vitamin K to avert the issues.

2. Anticonvulsants –

If the anticonvulsants are taken during pregnancy or while breastfeeding then it may increase the risk of Vitamin K deficiency in the fetus or infants.

3. Lowering down cholesterol levels, medications –

These medicines are known for interfering between the fat absorption in the body. On the other hand, vitamin K is a substance of fat-soluble and dietary fats are required to absorb vitamin K in the body. Thus, people taking such medicines are more prone to Vitamin K deficiency.

In order to ensure that the body has an adequate amount of nutrients, then simply follow a balanced diet that is rich in fruits and leafy vegetables in combination with the perfect fitness regime. Always consult your doctor before starting any vitamin K supplements.
