Our assessment
The evidence shows that calcium is a critical mineral for your health, but it requires careful attention to dosing and timing. For Genestra Brands Iron, data on this specific product is not available, so we rely on the general safety profile of calcium supplements [NIH ODS].
How it works
Calcium acts as a structural building block for your bones, supporting bone density and mineral deposition. It also functions as a nervous system regulator, helping with muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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
Start by assessing your total calcium intake from food and supplements to avoid exceeding safe upper limits. Take calcium supplements separately from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin to prevent absorption issues [NIH ODS].
