Our assessment
The evidence shows that NutriCology Calcium Magnesium Citrate is a supplement with a well-established primary ingredient, calcium, which supports bone health. However, you need to be aware of the significant safety considerations and potential medication interactions before taking it. Our assessment is that this supplement can be beneficial for individuals with a confirmed need for additional calcium, but it is not appropriate for everyone.
How it works
Think of calcium as the structural foundation for your bones and a key component for nerve and muscle function. The calcium in this supplement supports bone mineralization and density, while also playing a role in neuromuscular relaxation and nerve signaling [NIH ODS]. This means it helps keep your skeleton strong and your muscles and nerves working properly.
Safety profile
The FDA has received a total of 592,059 adverse event reports for this product category [FDA data]. Regarding calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Extremely 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]. Data on side effects specifically for the magnesium citrate component in this product is not available.
Our recommendation
We recommend you consult with your healthcare provider before starting this supplement. This is especially important if you take any medications, as calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Do not exceed the recommended dose on the label, and be aware of the serious risks associated with high calcium intake [NIH ODS]. If you are at risk for heart disease or prostate cancer, discuss the risks versus benefits with your doctor.
