"I'm only on the third day, but had been using another cheaper berberine supp for two months and did not really notice any reduction in blood glucose. I've had a CGM for 45 days so able to track and test with more data now. I got this berberine supplement after reading about poor results with some manufactures products. Looked and saw that the cheaper supplement I had been using had very few reviews.

Took Sat, Sun and now Mon. Yesterday was a super good day. I have a prediabetic history with A1C at 5.5 two months ago. The CGM initially showed big spikes (for me) up to 170-180 after a bowl of oatmeal for example. I'm on a pescatarian whole food diet and that has help drop those spikes down to 140-150. And I have seen even more improvement on some days in the last two weeks, but yesterday stood out after about three doses of this berberine.

Fairly large lunch and then dinner with whole grain bread, beans, chickpeas. About 700-800 calorie meals and my blood glucose peaked at about 125 and quickly came back to 100.

I just took another one before my three toast + eggs + avocado + protein shake + berries & yogurt mid-morning breakfast. 75 min later my peak at 108 and now down to 98. I generally get a second peak, but always smaller than the first. I have not seen these low numbers before at all. Not even close. This same breakfast has pushed me up to 145 before. The best peak was 128 or so. If the peak was truly 108... Wow. game change.

Update 1: After a few more days of testing, I'm seeing incredible results from the CGM. Over night sleeping levels are lower and consistent. Pre-breakfast values in the low 90s whereas before they would jump just above 100. Almost no jump in glucose after breakfast. I did get a response after eating more carbs last night for dinner. Jumped to 130 and back down within 10 min to the 80s."

"I’m not a scientist and I can’t speak as to the mechanism of how this works. I’m sure, since you’re checking out Berberine, you’re familiar or have been recommended this supplement for one reason or another. I’ve also never tried another brand so I can’t speak as to this particular one. *However* I have been obsessed with food for as long as I can remember. Type II diabetes and obesity run in my family. I myself struggle with fat gain and teeter on the obese/overweight line with a history of pre diabetes. I understand energy balance and being in a calorie deficit to lose body fat. However, it always seems insurmountable to achieve even a mild to moderate calorie deficit because I’m constantly thinking about food. Constantly. This supplement isn’t magic. It doesn’t “suppress” my appetite in the way that I “forget to eat” (not gonna happen lol.) However, it *does* get me to a more reasonable sensitivity to insulin where I can rationally talk myself out of binge eating. I can stick to a moderate caloric deficit more easily. Ever time I stop taking this supplement, my hunger cravings take over. I take a rather large dose of 1500 mg per day, with no issues. So this is a 30 day supply for my personally. This is a staple for my personal insulin sensitivity/blood sugar issues. Hopefully it will work for you too."

"So far I can say this product has helped me with bowel movement. I suffer from constipation & noticed I am becoming a regular since taking the pill. It’s being a week. Also, I noticed my stools are soft. I read some people got diharrea & might be because they don’t suffer from constipation like me. No cramping or the like. I take the pill right before every meal 3 times per day. As far as glucose hard to tell but I noticed my hunger has decreased as long as the effect of the pill continues. Other than no dude effects but all positive. ????"
