Why this happens
Black cohosh and vitamin B2 are processed by the body through different pathways. Vitamin B2 is a water-soluble vitamin that is absorbed in the small intestine and excreted through urine. Black cohosh is metabolised primarily by the liver. There is no evidence that they interfere with each other's absorption, metabolism, or effectiveness.
What you should do
You can continue to take both supplements as directed. However, always inform your doctor or pharmacist about all supplements you are taking, especially if you have a history of liver problems, as black cohosh has been rarely linked to liver issues.

Can I take Esomeprazole and Magnesium together?
Taking esomeprazole for a long time (usually more than three months) can lower the levels of magnesium in your blood. This can lead to symptoms like tiredness, muscle spasms, or an irregular heartbeat. Additionally, if you take magnesium as an antacid or supplement at the same time as esomeprazole, it might slightly interfere with how well the medicine is absorbed.
