Nature's Bounty Calcium Magnesium Zinc
Brand: Nature's Bounty · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that this combination supplement provides foundational minerals, but you should be aware of specific intake limits and potential risks. Calcium, magnesium, and zinc each play distinct roles, and taking them together is convenient for general wellness support. However, the data highlights important safety considerations, particularly around calcium intake [NIH ODS].
How it works
Think of calcium as a structural builder for your bones, supporting bone density and mineral deposition [NIH ODS]. Magnesium acts as a muscle relaxant, supporting neuromuscular relaxation and nerve signaling [NIH ODS]. Zinc contributes to immune function and cellular health. Together, they cover core physiological processes that decline with age or poor diet [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High calcium levels in 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]. Data not available for magnesium or zinc specific adverse event counts from this source.
Our recommendation
Start by assessing your dietary calcium intake before adding this supplement. If you take other medications, separate your calcium dose by at least two hours to avoid absorption issues [NIH ODS]. Stick to the label's serving size — do not exceed it — and consult your healthcare provider if you have a history of kidney stones, heart disease, or take prescription medications.
