Our assessment
The evidence shows that while this product is marketed as a zinc supplement, the primary data available is for calcium. For a product labeled as GNC Zinc 100, the specific benefits for zinc are not detailed in the provided data. You should be aware that calcium, not zinc, is the ingredient with available safety and interaction information here [NIH ODS].
How it works
Based on the data provided, the ingredient calcium works through bone mineralization, supporting bone density and mineral deposition. It also supports neuromuscular relaxation and nerve signaling [NIH ODS]. Think of calcium as a key mineral for your bone structure and muscle function.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, but the specific report count for this product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High blood and urine calcium levels 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
Given that the data provided focuses on calcium rather than zinc, you should seek specific zinc data from your healthcare provider before starting this supplement. If you are taking medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, be aware that calcium can reduce their absorption [NIH ODS]. For the intended zinc benefits, data is not available in this analysis.
