The Vitamin Shoppe Calcium Magnesium Zinc
Brand: The Vitamin Shoppe · Form: TABLET [E0155]
Our assessment
The evidence shows that this combination supplement provides two essential minerals and one trace element that support foundational body functions. Calcium is critical for bone mineralization and neuromuscular signaling, while magnesium and zinc play supporting roles in immune function and enzymatic reactions [NIH ODS]. However, the data highlights important safety considerations, particularly regarding calcium intake, that you need to weigh carefully.
How it works
Think of calcium as a structural builder—it supports bone density and mineral deposition, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. Magnesium and zinc work alongside calcium to support these processes, though specific mechanism data for these two ingredients is not provided in the available data.
Safety profile
Data not available for specific side effects of this combination product. However, for the calcium component, FDA received a total of 592,059 adverse event reports across all supplement categories. High calcium intake can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and poor muscle tone [NIH ODS]. There is also a potential increased risk of heart disease and prostate cancer with high intakes [NIH ODS]. Calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Before starting this supplement, review your total daily calcium intake from food and other supplements. Do not exceed the tolerable upper intake level unless directed by your physician. If you take any of the medications listed above, take this supplement at least two hours apart from those medications [NIH ODS]. For most people, getting calcium from food sources is safer and more effective than relying on supplements for bone health [NIH ODS]. Start with a lower dose if you choose to use this product, and monitor for any digestive discomfort.
