Herb Pharm Yellow Dock

Our assessment

Our assessment: The evidence shows that while yellow dock root has traditional uses, the specific data for this product is limited. Based on the information provided, we cannot make a strong recommendation for Herb Pharm Yellow Dock. The primary ingredient data available is for calcium, not yellow dock itself, which means the health effects of this specific supplement are not well-defined by the data you provided.

How it works

Data not available. The provided data does not include a mechanism of action for yellow dock. For the ingredient calcium, which is listed in the data, it works through bone mineralization to support bone density and mineral deposition, as well as neuromuscular relaxation to support muscle relaxation and nerve signaling [NIH ODS]. This information does not apply to the yellow dock product.

Safety profile

Data not available for yellow dock specifically. The FDA has received 592,059 total adverse event reports across all supplements in the database, but no specific report count is provided for yellow dock [FDA data]. For the ingredient calcium, high intakes might increase the risk of heart disease and prostate cancer, and high levels in the blood can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. These calcium side effects are not necessarily applicable to the yellow dock product.

Our recommendation

Our recommendation: Because the data provided does not contain specific evidence on yellow dock's efficacy or safety, we cannot recommend this product for any specific health purpose. If you choose to use it, be aware that the data on its active constituents is not available. Always consult your healthcare provider before starting any new supplement, especially if you take medications, as calcium supplements may reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
