Unlike many other fat-soluble vitamins, there is no established Tolerable Upper Intake Level (UL) for Vitamin K2 from dietary or supplemental sources. This fact often surprises people who wonder what happens if I have too much vitamin K2. The good news for most healthy individuals is that natural vitamin K2, consumed from food or supplements, poses a very low risk of toxicity, even at high doses.

While there is no established Tolerable Upper Intake Level (UL) for natural vitamin K1 and K2 due to their low potential for toxicity, many people still ask, what are the symptoms of too much vitamin K2? In fact, the most serious risks associated with vitamin K overdose are linked to a toxic synthetic form no longer in use, or impact specific, vulnerable populations like newborns, not healthy adults consuming typical dietary or supplemental amounts.

While excess intake is very rare from dietary sources of natural vitamin K, the synthetic form (menadione) is highly toxic. Understanding **what happens if your vitamin K is too high?** is crucial for certain individuals, especially those taking specific medications or supplements.
