Our assessment
Our assessment: The evidence shows that Solgar Calcium Magnesium Citrate provides two essential minerals that work together to support your bone health and muscle function. Based on the data, calcium is critical for bone mineralization and neuromuscular relaxation [NIH ODS]. You should be aware that while this supplement can help you meet your nutritional needs, the data on calcium supplementation carries important safety considerations that require your attention.
How it works
Think of calcium as a structural builder for your bones — it supports bone density and mineral deposition, helping keep your skeleton strong [NIH ODS]. At the same time, calcium acts as a nerve and muscle regulator, supporting muscle relaxation and proper nerve signaling [NIH ODS]. This dual role is why getting enough calcium is essential for your daily function and long-term bone health.
Safety profile
The FDA has received a total of 592059 adverse event reports for this product category [FDA data]. The data warns that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in your 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]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on interactions with magnesium citrate specifically is not available.
Our recommendation
Our recommendation: Take this supplement exactly as directed on the label, and do not exceed the recommended dose. Given the potential risks from high calcium intakes, you should speak with your healthcare provider before starting this supplement, especially if you take any of the medications listed in the safety section [NIH ODS]. For the most personalized advice, ask your doctor to check your calcium levels and kidney function before you begin supplementation.
