Allergy Research Group Magnesium Citrate
Brand: Allergy Research Group · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product is a calcium supplement, not a magnesium supplement as the name suggests. For a general audience seeking bone and nerve health support, calcium is a well-established mineral, but you must be careful with dosing and potential risks. Data not available for magnesium-specific benefits from this product.
How it works
Think of calcium as a structural builder and nerve messenger. It supports bone density and mineral deposition for strong bones and helps your muscles relax and nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for this ingredient category. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels in 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 reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are looking for a magnesium supplement, this product is mislabeled and you should choose a different one. For calcium, get your daily needs from food first. If you supplement, take it with food and separate from other medications by at least 2 hours [NIH ODS]. Avoid exceeding 2,500 mg total daily calcium from all sources [NIH ODS].
