Our assessment
The evidence shows that this specific product, Rx Vitamins Zinc Lozenges, contains calcium as its primary active ingredient. Our assessment is that while calcium is essential for health, you should be aware of the specific risks and interactions associated with calcium supplementation [NIH ODS].
How it works
Think of calcium as a structural and signaling mineral. It supports bone mineralization and density, and it plays a role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. 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] [FDA data].
Our recommendation
Data not available for a specific daily dose for this product. If you take calcium supplements, be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. You should take calcium at least two hours apart from these medications [NIH ODS].
