CVS Pharmacy Natural Calcium, Magnesium & Zinc USP
Brand: CVS Pharmacy · Form: SUPPLEMENT FORM, UNKNOWN [E0177] On Market
Our assessment
The evidence shows that a calcium, magnesium, and zinc combination supplement is a reasonable way to support your daily mineral intake, but it is not a substitute for a balanced diet. For calcium specifically, the data confirms a role in bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a key structural component for your bones and a critical signaling molecule for your nerves and muscles. It supports bone density through mineral deposition and helps your muscles relax after contraction [NIH ODS]. This combination of minerals works together to support overall skeletal and nerve health.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, 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 reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by confirming your daily calcium needs with your healthcare provider, as the RDA varies by age and sex. Take this supplement with food to improve absorption, and separate it from any thyroid or antibiotic medications by at least two hours [NIH ODS]. Data not available for the exact amounts of magnesium and zinc in this specific product, so check the label carefully. Do not exceed the recommended serving size without medical guidance.
