Our assessment
The evidence shows that this supplement contains calcium, a mineral essential for bone health and nerve function. Our assessment is based strictly on the data provided. Calcium supports bone density and mineralization, and aids in neuromuscular relaxation [NIH ODS]. However, the data also highlights important safety considerations you need to be aware of before using this product.
How it works
Think of calcium as a structural builder for your skeleton and a signal regulator for your nerves. It works through bone mineralization to deposit minerals into your skeleton, helping maintain strong bones. At the same time, it supports neuromuscular relaxation, meaning it helps your muscles relax after contracting and aids in proper nerve signaling [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, the data indicates that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to proceed with caution. Before taking this supplement, speak with your healthcare provider, especially if you have a history of kidney disease, heart problems, or take prescription medications. Do not exceed the recommended dose on the label, as high calcium intakes carry significant risks. If you experience nausea, constipation, or unusual tiredness, stop use and consult a professional [NIH ODS] [FDA data].
