Our assessment
The evidence shows that this supplement provides two essential minerals, but you need to be aware of important safety limits and medication interactions. Data not available on the specific product’s ingredient amounts, so we rely on general nutrient profiles.
How it works
Calcium supports bone mineralization by helping deposit minerals into your skeleton, while also promoting neuromuscular relaxation for proper nerve signaling and muscle function [NIH ODS]. Magnesium works alongside calcium in many of these processes.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, though specific product reports are not available. High calcium intakes may increase risk of heart disease and prostate cancer [NIH ODS]. Excess calcium can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and elevated risk of death from heart disease [NIH ODS]. Calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Take this supplement only if you know you need extra calcium and magnesium. Check with your doctor about medication timing — separate calcium from thyroid medication and antibiotics by at least 4 hours [NIH ODS]. Stick to the recommended dose on the label and do not exceed 2,500 mg of total calcium daily from all sources [NIH ODS].
