Our assessment
The evidence shows that while this product contains Devil’s Claw, our data on the specific ingredient Calcium provides the most relevant safety and interaction information for this supplement. You should know that calcium is a mineral essential for bone and nerve health, but high intakes carry real risks [NIH ODS].
How it works
Think of calcium as a building block for your bones and a signal conductor for your nerves. It supports bone mineralization and density, and helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA has received 592,059 total adverse event reports for the products in this data set. For calcium specifically, 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. Some research also suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS] [FDA data].
