## Questions & Answers

**Q: Relentless Improvement: do you self test the purity of overseas ingredients before production of D-Serine?**
A: When the active arrives we sample it and send it out to a third-party analytical testing laboratory based in the USA. The material is quarantined until test results are received back. **As is required for GMP compliance.**

**Q: Is this made in the usa? is it based on porcine aka pig, or shell fish?**
A: The active is not available from USA suppliers. As you are well aware, our high-tech manufacturing was gutted and shipped offshore decades ago. Downstream of the active, all remaining manufacturing and testing is USA.  The is no porcine, or shellfish.

**Q: Relentless Improvement: do you third party test the purity of overseas ingredients before production of third D-Serine?**
A: As required under GMP, yes. OF COURSE. 

We have conducted full third-party testing since we began business 17 years ago, before it was required by law.

I'll also point out, 99% of actives used by ALL supplement companies come from "overseas" as USA manufacturing was gutted decades ago.

**Q: For anyone who's tried both L-Serine & D-Serine, did D-Serine really achieve better results?**
A: Because D-Serine has a poor absorption rate orally one must take a lot. I gave to my wife for three months when recovering. I don't know how well it worked but I would do again.
