Tag: K2 toxicity

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.

According to the National Institutes of Health (NIH), no Tolerable Upper Intake Level (UL) has been established for natural vitamin K1 and vitamin K2, suggesting a low risk of toxicity from excessive consumption via food or supplements.
