Our assessment
The evidence shows that this supplement provides two essential minerals for bone and muscle health. Our assessment: Calcium from this product can effectively support bone density when taken as directed, but you must be aware of the safety limits and potential interactions. Data for the magnesium component is not available in the provided information.
How it works
Think of calcium as a key building block for your skeleton. It works through bone mineralization to support bone density and mineral deposition, and it also supports neuromuscular relaxation by aiding muscle relaxation and nerve signaling [NIH ODS]. For this to be effective, you need adequate vitamin D, which is not listed in the provided ingredient data for this product.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels 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
Start by checking if you actually need a supplement, as most people get enough calcium from food. If you decide to take it, do not exceed the total recommended daily intake from all sources. Because calcium can interfere with thyroid medication and antibiotics, take this product at least 2 hours apart from those drugs [NIH ODS]. Always talk to your doctor before starting, especially if you have kidney issues or a history of heart disease. Data for a specific dosage recommendation for this product is not available.
