Herb Pharm Black Cohosh

Our assessment

The evidence shows that black cohosh is a herb traditionally used for menopausal symptoms, but the data provided is insufficient to make a specific efficacy claim for this product. Our assessment is based on the available ingredient data, which focuses on calcium, not black cohosh. For a supplement like Herb Pharm Black Cohosh, you should know that the active ingredient is not calcium, and the specific clinical evidence for this product is not available in the data provided.

How it works

Since the provided data only covers calcium, we can explain how calcium works in the body. Calcium acts as a master regulator for bone mineralization, supporting bone density and mineral deposition [NIH ODS]. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS]. For black cohosh specifically, data on its mechanism is not available from the provided sources.

Safety profile

The FDA adverse event database contains a total of 592,059 reports across all supplements, but specific report counts for this product or black cohosh alone are not provided [FDA data]. For the ingredient calcium, side effects include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease when levels are too high [NIH ODS]. Also, calcium can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For black cohosh-specific side effects, data is not available.

Our recommendation

We recommend that you consult with your healthcare provider before taking Herb Pharm Black Cohosh, especially since the data provided does not include specific studies or adverse event counts for this herb. For menopausal symptom management, you should look for products with published clinical trials. If you choose to use this supplement, monitor for any side effects and report them to the FDA. For bone health, ensure adequate calcium intake, but do not exceed the tolerable upper intake level without medical supervision [NIH ODS].
