Our assessment
The evidence shows that while the product is labeled as zinc, the data provided concerns calcium. For calcium, our assessment is that it is a critical mineral for bone health, but supplementation requires careful consideration. You should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder and a cellular messenger. It supports bone mineralization and density, and it is essential for neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all products. Specific side effects for calcium include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms. Very high blood levels can cause poor muscle tone, poor kidney function, low phosphate levels, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because the data provided is for calcium and not the labeled ingredient zinc, data for zinc is not available. For calcium, our recommendation is to prioritize getting it from food sources first. If you do supplement, take it with food and consult your doctor, especially if you take any of the medications listed under interactions [NIH ODS].
