Nature's Bounty Calcium Magnesium
Brand: Nature's Bounty · Form: SUPPLEMENT FORM, OTHER [E0172] On Market
Our assessment
The evidence shows that Nature's Bounty Calcium Magnesium is a straightforward supplement providing two essential minerals. Calcium is crucial for bone density and mineralization, while magnesium supports muscle relaxation and nerve signaling [NIH ODS]. For most people, getting these nutrients from food is ideal, but this supplement can help fill dietary gaps.
How it works
Think of calcium as a structural building block for your bones and teeth, while magnesium acts as a relaxation mineral for your muscles and nerves. Together, they support neuromuscular function and bone health. Calcium's role in bone mineralization helps maintain density, and magnesium supports the relaxation phase of muscle contraction [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High calcium levels can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and poor muscle tone [NIH ODS]. You should be aware that calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your dietary calcium intake from dairy, leafy greens, and fortified foods. If you need a supplement, take it with food and separate from other medications by at least two hours. Do not exceed the Tolerable Upper Intake Level without medical supervision. Always consult your doctor before starting, especially if you have kidney issues or take prescription medications [NIH ODS].
