The Vitamin Shoppe Calcium Magnesium Zinc
Brand: The Vitamin Shoppe · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that the combination of calcium, magnesium, and zinc in this supplement can support bone health, but you need to be aware of specific risks and interactions. Calcium is critical for bone mineralization and neuromuscular relaxation [NIH ODS]. However, the data is clear that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It supports bone density and mineral deposition, while also helping your muscles relax and your nerves signal properly [NIH ODS]. Magnesium and zinc work alongside calcium, though specific data on these two ingredients in this exact product is limited.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories [FDA data]. 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 also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our assessment: You should not exceed the RDA for calcium without medical supervision. If you take any prescription medications, especially antibiotics or thyroid medication, take this supplement at least 2 hours apart from those drugs [NIH ODS]. Data on the specific magnesium and zinc dosages in this product is not available, so consult your pharmacist or doctor before starting.
