Can I take Black cohosh and Folic acid together?

Why this happens

Black cohosh and folic acid are processed by the body through different pathways. Black cohosh is primarily broken down by liver enzymes (specifically the CYP450 system), while folic acid is a water-soluble B vitamin that follows a separate metabolic route. They do not interfere with each other's absorption or effectiveness.

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 or are pregnant, as black cohosh may not be suitable for everyone.

Pregnancy

Do not use black cohosh during pregnancy. It may stimulate uterine contractions, potentially increasing the risk of miscarriage or premature labour.

Liver disease

Black cohosh has been linked to rare but serious cases of liver failure. You must stop taking it and see a doctor immediately if you develop yellowing of the skin or eyes, dark urine, or severe stomach pain.

Hormone-sensitive conditions (e.g. breast cancer)

Because black cohosh may act like the hormone oestrogen, you should not use it if you have a history of breast cancer, uterine cancer, or endometriosis without specialist medical supervision.

Vitamin B12 deficiency (Pernicious anaemia)

Folic acid can mask the symptoms of a Vitamin B12 deficiency. If taken without B12 when a deficiency exists, it can allow permanent damage to the nervous system to occur before the problem is detected.

Alcohol

Black cohosh has been linked to rare but serious cases of liver damage. Because alcohol also puts strain on the liver, it is advisable to limit or avoid alcohol consumption while taking this supplement to reduce the risk of liver toxicity.
