Brand: Nature's Bounty · Form: TABLET [E0155]
Our assessment
The evidence shows that this product combines two well-studied nutrients, but the specific formulation in Nature's Bounty Vitamin C + Zinc is not covered by the data provided. For the ingredient Calcium, which is listed in the data, we have strong evidence for its role in bone health, but the data does not include specific numbers for Vitamin C or Zinc for this product. Our assessment is that while the individual ingredients have known benefits, you should be aware of the specific risks and interactions associated with high-dose minerals like Calcium [NIH ODS].
How it works
Think of Calcium as a structural builder and a signal messenger. It supports bone mineralization by helping deposit minerals into your skeleton, and it also plays a critical role in neuromuscular relaxation, allowing your muscles to relax and your nerves to signal properly after contraction [NIH ODS]. Without sufficient Calcium, your body will leach it from your bones, which can weaken them over time.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, though the specific number for this product is not available. For the Calcium component, safety data shows that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels of calcium 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].
Our recommendation
Data not available for a specific recommendation on this exact product. However, if you are taking Calcium supplements, be cautious: Calcium can reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Do not take this supplement within two hours of those medications. For general use, stick to the RDA and get your levels checked before supplementing with high-dose minerals [NIH ODS].
