Herb Pharm Horsetail
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that Horsetail is a source of calcium, a mineral essential for bone health. However, relying solely on this herb for your calcium intake is not supported by strong clinical data. The data provided does not include specific studies on Horsetail itself, so we must focus on the calcium it may provide [NIH ODS].
How it works
Calcium from any source, including Horsetail, plays a key role in bone mineralization, helping to support bone density and mineral deposition. It also assists with neuromuscular relaxation, supporting proper muscle relaxation and nerve signaling [NIH ODS]. Think of it as a structural building block for your skeleton and a messenger for your nervous system.
Safety profile
Data not available for Horsetail-specific side effects. The FDA received a total of 592,059 adverse event reports across all products, but this number is not specific to Horsetail. For calcium, high intakes can lead to risks including constipation, nausea, and abnormal heart rhythms, and may increase the risk of heart disease and prostate cancer [NIH ODS]. Calcium can also reduce the absorption of medications such as tetracycline antibiotics and levothyroxine [NIH ODS].
Our recommendation
We cannot recommend Horsetail as a primary calcium source due to a lack of direct evidence. If you are interested in calcium for bone health, consider a standard calcium supplement with vitamin D. Always consult your doctor before starting any new supplement, especially if you take prescription medications [NIH ODS].
