Allergy Research Group Calcium Magnesium Citrate
Brand: Allergy Research Group · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is an essential mineral for bone health, but it is not a supplement to take casually. Our assessment is that you should only use calcium supplements like this one if you have a confirmed dietary gap, as high intakes carry real risks [NIH ODS].
How it works
Calcium is a critical structural component for your bones and teeth. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the raw material your body uses to keep your skeleton strong and your muscles and nerves communicating properly.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Before starting this supplement, we recommend you assess your total calcium intake from food and other supplements. Do not exceed the Tolerable Upper Intake Level without medical supervision. If you take prescription medications, especially antibiotics or thyroid medication, take calcium at least two hours apart [NIH ODS]. Our recommendation is to prioritize dietary calcium from food sources first and only use this product to fill a specific gap confirmed by a healthcare provider.
