According to the National Institutes of Health, no adverse effects from vitamin K consumption from food or supplements have been reported in humans or animals, leading to no established Tolerable Upper Intake Level (UL). This low toxicity profile is reassuring for consumers, but it raises questions about intake levels, especially for the menaquinone (K2) form.

According to health authorities like the National Academy of Sciences, no tolerable upper intake level (UL) has been established for natural vitamin K2, indicating its high safety profile. This suggests that for most healthy adults, excessive intake is unlikely to cause toxicity, but there are important considerations.

According to the National Institutes of Health, no Tolerable Upper Intake Level (UL) has been established for vitamin K, including the K2 form, due to its low potential for toxicity from food and supplements. However, while naturally-sourced vitamin K2 is generally safe even at high intakes, there are important considerations regarding interactions with certain medications, raising the question: can you get too much vitamin K2?
