In the following section, we will have chance to discover some of the most common and worst vitamin K side effects on human health and know why you need to avoid these influences at all costs! Keep reading to not miss the interesting facts and knowledge about the usage of this vitamin!

1. Effect On Blood – Thinning Medications

One of the biggest vitamin K2 side effects on health is its potential to interact with blood-thinning medications. Blood-thinning medications work by inhibiting vitamin K. Suddenly increasing the vitamin K2 coming from any source, whether vitamin K2 supplements or vitamin K2-rich foods, may decrease the effect of blood-thinning medications. Cutting down on vitamin K2 may increase its effect. This unwanted side effect may seem more significant with vitamin K2 than vitamin K1. Even a small change in menaquinone intake may affect anti-coagulant medications.

When an allergic reaction turns up, vitamin K2 supplements are basically safe and non-toxic. Menaquinones may be metabolized with vitamin K2 differently than vitamin K1. For instance, vitamin K2’s effect coming from fermented foods on blood-thinning medications may last longer than vitamin K1’s effect.

This is actually one of the common side effects of vitamin K2 that you should know and try to be cautious when taking in vitamin K2 from any sources while taking blood-thinning medications.
