Review: Can’t beat Thorne, imitations need not apply! - As a woman experiencing pre-menopausal symptoms, I can’t recommend Thorne products enough! Their Niacinamide capsules have been a game changer for me. My holistic provider recommended Thorne as one of the cleanest and most effective supplement brands out there, and I can see why. I feel a noticeable difference in my skin, joint comfort, and overall sense of calm, especially when it comes to restful sleep. It’s hard to find such high-quality, natural supplements, and Thorne truly delivers. Knowing these are gluten-free and formulated without unnecessary additives gives me peace of mind. Highly recommend to anyone looking for clean, effective support!

**Q: What is the dosage for each capsule?**
A: According to Thornes website, 500mg per tablet.

**Q: How large are these capsules?**
A: The capsule used in Thorne’s Niacinamide product is an oblong, two-piece size 0 (or “single-aught”) capsule. A single-aught (size 0) capsule is designed to hold about 500 mg of material. You can see the various sizes and dimensions of all capsules by doing an online search using “capsule sizes” as the search term.

**Q: Is this extended release?**
A: The Thorne Niacinamide is not a sustained release supplement.

**Q: Where does the niacinamide originate? Is it from China?**
A: Because it is proprietary and confidential business information, Thorne does not disclose the country of origin of its raw materials. Thorne tells us: "Thorne Research sources its ingredients from around the world, including China. However, what is much more important than the country of origin of an ingredient is the testing that is done on that ingredient when it is received by the manufacturer. Thorne Research does not rely on the Certificate of Origin from an ingredient supplier. Instead, Thorne Research tests every single ingredient in our own in-house laboratory, regardless of the ingredient's country of origin, to verify the ingredient's identification, purity, and quality."
