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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Clearer Mind After Just Three Weeks! *by E***E on January 26, 2026* I started taking this supplement about 3 weeks ago.

Their main problem is they often discontinue products, so I'm not sure how long this is going to be around. The form of serine usually found from other vendors is L-serine, which is **not** the natural form of serine present in the body and brain. D-Serine is the correct isomer of serine present in the body and brain, and it's unusual to be able to find it available from anyone. Relentless Improvement so far seems to be the only source, so get it while you can! ## Frequently Bought Together - Relentless Improvement D-Serine - L-Serine Capsules (Third Party Tested) - 2,000mg Servings Used in Clinical Study, 180 Count, 500mg per Capsule (L Serine Amino Acid for Serotonin Production and Brain Support) by Double Wood --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/421187961-d-serine-amino-acid-700mg-90-count-vege-capsules](https://www.desertcart.sn/products/421187961-d-serine-amino-acid-700mg-90-count-vege-capsules) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-17*
