Solgar Magnesium Citrate

Our assessment

The evidence shows that as a clinical pharmacist, I can only provide an assessment based on the data provided for this specific product. For Solgar Magnesium Citrate, the data lists the ingredient as "Calcium," not magnesium. Based on the data provided, our assessment is that this supplement contains calcium. The data confirms that calcium supports bone density and neuromuscular relaxation [NIH ODS]. However, we cannot confirm the dosage or specific benefits of this product as a magnesium citrate supplement because the data does not match the product name. For a general assessment of calcium, it is a mineral that supports bone mineralization and nerve signaling [NIH ODS].

How it works

Think of calcium as a key structural component — it works by supporting bone density and mineral deposition, which is critical for strong bones. It also promotes neuromuscular relaxation, helping your muscles relax and your nerves send proper signals [NIH ODS].

Safety profile

Safety data is available for calcium. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. The 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].

Our recommendation

Based on the data provided, I cannot recommend Solgar Magnesium Citrate because the ingredient listed in the data is calcium. For calcium supplements, the data supports their role in bone health, but you must be cautious about high intakes and potential interactions with medications [NIH ODS]. If you are looking for a magnesium citrate supplement, data is not available for this specific product. For any supplement, consult with your healthcare provider before starting, especially if you take prescription medications [NIH ODS] [FDA data].
