Vitamin K

BCCT plans to write a summary on vitamin K. While our summary is in development, you can visit these sites:


The Lonestar Medical Group summary of Vitamin K lists several safety issues, including a number of herb-drug interactions. Of particular note is that Vitamin K can interfere with anti-coagulation therapy and can interact with drugs that alter coagulation. Read the summary for more details: Vitamin K.

For more in-depth information on cautions, adverse effects and interactions, see the TRC Natural Medicines Database summary on Vitamin K (subscription required).

Neil McKinney, ND also cautions not to use N-acetyl-cysteine during use of pro-oxidative therapy such as with vitamin K.1


BCCT does not recommend therapies or doses, but only provides information for patients and providers to consider as part of a complete treatment plan. Patients should discuss therapies with their physicians, as contraindications, interactions and side effects must be evaluated.

Dosage recommendations are available from these sources:
