Our assessment
The evidence shows that Jarrow Formulas Magnesium Optimizer is a product that includes calcium, a mineral with well-documented roles in bone health [NIH ODS]. Our assessment is that while calcium is essential, you should be aware of the specific risks and interactions associated with it, as detailed below.
How it works
Calcium acts as a master regulator for bone mineralization, supporting bone density and mineral deposition. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories, though a specific count for this product is not available. For calcium specifically, some research suggests that high 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for a specific dosage recommendation for this product. We recommend you consult your healthcare provider before starting this supplement, especially if you take any of the medications listed above. It is important to monitor your total calcium intake from both food and supplements to stay within safe limits [NIH ODS].
