The Vitamin Shoppe Calcium Citrate & Magnesium
Brand: The Vitamin Shoppe · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this supplement provides calcium and magnesium, two minerals essential for bone health and muscle function. For most adults, getting these nutrients from food is preferred, but a supplement can help fill dietary gaps. The key is to use the correct dosage and be aware of potential medication interactions [NIH ODS].
How it works
Think of calcium as the building block for your bones, supporting bone mineralization and density. Magnesium works alongside it to support muscle relaxation and nerve signaling. Together, they help maintain your body's structural framework and neuromuscular function [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For this specific product, data on side effects is not available. However, high calcium intakes from any source can lead to constipation, nausea, and abnormal heart rhythms. High levels in the blood may also cause poor muscle tone, extreme tiredness, and a high risk of death from heart disease [FDA data] [NIH ODS]. Additionally, calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Start by assessing your dietary calcium intake from dairy, leafy greens, and fortified foods. If you are consistently falling short, this supplement may help. Take it with food for best absorption, and separate it from thyroid medication or antibiotics by at least 4 hours. Consult your doctor before starting, especially if you have a history of kidney stones or heart conditions [NIH ODS].
