Herb Pharm Horsetail
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165] On Market
Our assessment
The evidence shows that Horsetail is a source of the mineral calcium. Calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, the data for Horsetail specifically is limited. We must rely on what is known about its calcium content, and the numbers here are not specific to the product itself.
How it works
Think of calcium as a key structural component for your bones and a signal regulator for your nerves and muscles. It supports bone density and mineral deposition, and it helps with muscle relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for specific side effects of Horsetail from the provided FDA data. However, for calcium, which is a key ingredient, high intakes can cause constipation, nausea, and weight loss [NIH ODS]. Very high levels in the blood and urine can lead to poor muscle tone, poor kidney function, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. The total FDA adverse event reports for all supplements in the database is 592,059, but this is not specific to Horsetail [FDA data].
Our recommendation
Because the evidence is limited to general calcium data, we cannot make a strong recommendation for this product. If you choose to use it, be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Always consult your healthcare provider before adding any supplement to your routine.
