Data for the ingredient calcium is provided, but for the product you asked about, zinc-specific data is not available in the provided information.
How it works
Based on the data for calcium, which is a different mineral, it works through bone mineralization by supporting bone density and mineral deposition, and through neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS]. For the zinc citrate product you are asking about, specific mechanism data is not provided.
Safety profile
Data not available for the specific product. The FDA has received a total of 592,059 adverse event reports for all supplements, but no specific side effect report count is provided for this zinc product [FDA data].
