Herb Pharm Stinging Nettle
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that this product is labeled as Stinging Nettle, but the data provided only covers the ingredient Calcium. We cannot assess the benefits of stinging nettle specifically because no data on that herb was supplied. For the calcium component, our assessment is that it plays a key role in bone health and nerve function, but the risks associated with high intakes are significant and require careful attention [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, which is critical for maintaining strong bones as you age. It also acts as a neuromuscular relaxant, helping your muscles contract and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all dietary supplements, though the specific count for this product is data not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels in the blood and urine 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] [FDA data].
Our recommendation
If you are taking this product for its calcium content, be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take calcium supplements separately from these medications by at least two hours. We recommend you do not exceed the established dietary guidelines for calcium without consulting your doctor, as the risks of high intake are serious [NIH ODS].
