Q: Did anyone experience a detox when starting?

Yes. I started taking one capsule three times a day right before a meal, about a week ago. I feel like I have a mild flu. I'm going to empty half of the powder out and just take 1/2 a dose and see how that goes. By the way, I've lowed my fasting glucose by 20 pts in the morning. I don't want to stop taking this because I think it's helping me, but I do not like this flu like feeling.

Q: since so many pharmaceuticals are now produced in China. is there any way to tell if this is also produced in China? i couldn't get a straight answer

Thorne Research manufactures their products in their new state-of-the-art manufacturing facility in South Carolina, USA. 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 their own in-house laboratory, regardless of the ingredient's country of origin, to verify the ingredient's identification, purity, and quality. Please contact Thorne or iServe directly if you would like more information. We are both happy to help!

Q: What are the ingredients listed on the bottle?

Berberine HCL (from Indian Berberry extract((root) (Berberis aristata) 1 gOther ingredients: Hypromellose (derived from cellulose) capsule, Microcrystalline Cellulose, Silicon Dioxide, Leucine.

Q: Is this product fully absorbed? i read that dihydroberine is the preferred form to get almost 100% bioavailability. regular berebrine is only 20%.

The berberine ingredient in Thorne’s Berberine-500 has consistently shown reliable absorbability and clinical efficacy. Although it is true that berberine has variable absorbability, consistent dosing with a high-quality ingredient, such as the berberine used in Thorne’s Berberine-500, has shown to be effective.
