I'm sure you googled it and looked at the second result, but if not....
Given the strong track record of safety, the National Academy of Sciences did not choose to establish a Tolerable Upper Intake Level (UL) for vitamin K. Further evidence for the safety of dietary vitamin K comes from research studies where doses of vitamin K at 500 times the Adequate Intake (AI) did not lead to observable toxicity.
