## Questions & Answers

**Q: Which country is it made at (not distributed from, but “made at”)?**
A: Amityville New York, USA

**Q: how big are tablets?**
A: 1/2 inch round tablet, 1/8 in thickness.

**Q: What is exp date?**
A: The one they shipped me was 8/2025

**Q: Why does it have prop 65 warning? Is it the bottle or is something in the pills?**
A: It is something in the product. The manufacturer does not have to disclose specifically what it is or the risk is involved. California has about a bazillion substances on their Prop 65 list without specifying anything about them. The State of California suggests you contact the manufacturer direct to find out what it is. That being said, my bottle does NOT have a Prop 65 warning nor have any of my past purchases of this brand.
