PhysioLogics Magnesium Citrate
Brand: PhysioLogics · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is a critical mineral for bone health. While it is essential for bone mineralization and neuromuscular relaxation, you should be aware of potential risks at high intakes, including a possible increased risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, ensuring your bones remain strong. At the same time, it acts as a nerve relaxant, supporting muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports for this product's ingredient category. 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] [FDA data]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
You should not exceed the recommended daily intake without medical supervision, as high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. If you take any medications for thyroid issues, infections, or bone density, take calcium supplements at a different time of day to avoid absorption issues [NIH ODS].
