Why this happens
Black cohosh and vitamin B12 are processed by the body through different pathways. Black cohosh is primarily broken down by the liver, while vitamin B12 is absorbed in the small intestine and does not interfere with the liver enzymes that process black cohosh. They do not have overlapping effects on the body's systems.
What you should do
You can continue to take both supplements as directed. However, always inform your doctor or pharmacist about all the supplements you are taking, especially if you have a history of liver problems, as black cohosh has been rarely linked to liver issues.
