SuperiorLabs Magnesium Citrate
Brand: SuperiorLabs · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product contains calcium, not magnesium citrate, based on the data provided. For a general audience seeking bone and nerve health support, calcium is a foundational mineral, but the product label appears inconsistent with the ingredient listed in the data. Our assessment: you should verify the product label carefully before use, as the ingredient data supplied here points to calcium, not magnesium.
How it works
Calcium acts as a key structural component for your bones, supporting bone density and mineral deposition through a process called bone mineralization [NIH ODS]. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS]. Think of calcium as the building block your body needs for strong bones and steady nerve function.
Safety profile
Total adverse event reports for the product line are 592,059 [FDA data]. Specific side effects reported with high calcium intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. High blood and urine calcium levels can also cause poor muscle tone, poor kidney function, and low phosphate levels [NIH ODS]. Some research suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
We recommend you first check the product label to confirm you are taking the correct supplement. If you are using calcium, aim to meet your needs through food sources when possible, and do not exceed the tolerable upper intake level without medical supervision [NIH ODS]. Be aware that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin — take calcium at least two hours apart from these drugs [NIH ODS]. Start with a low dose and monitor for constipation or nausea. Data not available for magnesium citrate benefits or interactions in this report.
