Physician's Preference Magnesium Citrate 200 mg
Brand: Physician's Preference · Form: TABLET [E0155]
Our assessment
Our assessment: This product contains one ingredient — calcium — at a dose that is not specified in the data provided. The evidence shows that calcium is essential for bone health and nerve function, but the data provided does not include any information about magnesium citrate or a 200 mg dose [NIH ODS]. You should be aware that this product label lists calcium, not magnesium, as the active ingredient based on the data we have. The data on calcium is clear: it supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural key for your skeleton and a signal regulator for your nerves and muscles. It works by depositing into bone tissue to maintain density and by helping your muscles relax and your nerves send signals properly [NIH ODS]. Without adequate calcium, your body may pull it from your bones, which can weaken them over time.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available [FDA data]. The data shows that high calcium 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Data not available for the specific 200 mg magnesium citrate claim. Based on the provided data, this product is labeled as containing calcium. If you are seeking a calcium supplement, the data confirms it supports bone health, but you should be cautious about exceeding recommended intakes due to the safety concerns listed [NIH ODS]. Always separate calcium supplements from the medications listed above by at least 2 hours. Consult your doctor before starting any new supplement, especially if you have kidney issues or take prescription medications.
