Unlike what some people believe, vitamin K1, which is found primarily in leafy greens, cannot be converted by the body into vitamin K2, although this conversion is possible in some other animal species. Therefore, many people are deficient in this nutrient without knowing it, since it is one of the most overlooked in our daily diet.
Vitamin K2 wasn’t widely studied until recently, and while the research is still relatively new, there have been confirmations regarding vitamin K2 impact on bone health and short-chain menaquinones to long-chain menaquinones.

Blood Thinning: Due to the blood-thinning effects of vitamin K, which is great for heart health and arterial integrity, it can cause problems for those with bleeding issues, or for those who are already taking medication to thin their blood. Be sure to speak with a doctor before beginning treatment with vitamin K2 supplements.
Allergies: Unlike many other vitamins, it is possible to develop an allergy or sensitivity to vitamin K2, which may make it more difficult to ensure your body has enough of it. The allergic reactions are usually mild and harmless, however, and there is no risk of toxicity. This is different than vitamin K3 (menadione), which is known to be highly toxic.
