Herb Pharm Horsetail
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that this product, Herb Pharm Horsetail, contains calcium as a key ingredient. Our assessment is that you should be cautious: while calcium is essential for bone health, the specific horsetail formulation does not have robust clinical data to support its use for this purpose. The primary benefit you may receive comes from the calcium content, but the dosage and bioavailability from this herbal source are not clearly established [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone mineralization and density, and also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. However, for horsetail specifically, data on how it delivers this calcium is not available.
Safety profile
Safety data is limited. While FDA has received 592,059 total adverse event reports across all supplements, specific report counts for this product are not available. For calcium, high intakes can cause constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms. High levels also increase the risk of heart disease and prostate cancer [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
We recommend you do not rely on this product for calcium supplementation. The evidence does not confirm it provides a reliable or safe amount of calcium. For bone health, a standard, well-studied calcium supplement is a better choice. Data not available for the specific efficacy or safety of this horsetail formula. Always consult your doctor before starting a new supplement [NIH ODS].
