Natrol Calcium With Magnesium
Brand: Natrol · Form: TABLET [E0155]
Our assessment
Our assessment: Calcium is essential for your bones and nerves, but the evidence shows that taking it as a supplement requires careful attention to dosing and timing. This product combines calcium with magnesium, which supports muscle function, but you must be aware of the specific risks and interactions [NIH ODS].
How it works
Think of calcium as a building block for your skeleton and a signal conductor for your nerves. It supports bone mineralization and density, and it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all products. For calcium, high intakes may increase the risk of heart disease and prostate cancer. High blood levels can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available on the specific dosage of this product. For calcium, take supplements with food and separate them from thyroid medication or antibiotics by at least 4 hours [NIH ODS]. Do not exceed the tolerable upper intake level without a doctor's guidance. Start with the lowest effective dose and monitor for side effects like constipation or nausea [NIH ODS].
