It Works-- Amazingly Well.
I thought I'd try this after extensive research-- escalating health problems have been putting weight on for years while creating energy and illness issues that made it impossible to be consistent with good diet and daily exercise. I read all the reviews so I knew to take it with food. Some minor gas/discomfort, but very manageable, and I noticed very quickly that I felt full on very little food. On the second day it was clearly affecting my sleep patterns -- I no longer wake multiple times in the night, and am appropriately tired at bedtime. My energy is up and stable, and best of all, my exercise tolerance radically increased-- I want to exercise and can now exercise vigorously on long walks (something I have been unable to do for quite a while without pain & exhaustion) and can do a long fast walk and make it up 3plus flights of stairs-- I haven't been able to do that for years without feeling like I would pass out. I am able to eat a very lo cal diet without cravings or hunger, and in one week, my weight is down 4 lbs. Something threw my metabolism off 20 years ago & it escalated into a whole variety of bad issues that looped on each other-- this is fixing whatever is at the core of it. I heartily recommend you try it. (I have added a good quality probiotic to it, and take it with yogurt or kefir-- the research I read said that improves the positive effects.)

Great Results!…no negative side effects
I'm currently on my second bottle of Thorne Berberine and felt it was time to share my experience. After finishing my first bottle, my cholesterol had dropped by 42 points, which was a fantastic outcome. I do want to be completely transparent: I did not rely solely on berberine. Along with taking this supplement, I made several lifestyle changes, including cutting back on certain foods, increasing my daily movement, and making a conscious effort to drink more water. I believe the combination of these changes contributed to my success. I'm a big fan of Thorne products, and this supplement fit seamlessly into my existing stack. I initially took 2 capsules in the morning, then switched to 1 in the morning and 1 around 3 PM. After some experimentation, I found the best results came from taking 1 capsule first thing in the morning and the second a few hours before bed. In addition to the improvement in my cholesterol numbers, I've also lost 8 pounds, experienced more energy throughout the day, noticed that my food noise and cravings have significantly decreased, and my sleep quality has improved. My resting heart rate while sleeping has also improved, which was an unexpected bonus. Another positive for me is that I've experienced no negative side effects whatsoever. One important note: this is not a quick fix, and it's definitely not a magic weight-loss supplement. If you're looking for an effortless shortcut, you'll likely be disappointed. Be responsible, focus on improving your diet, staying active, and building healthy habits. In my experience, berberine worked best as a tool that supported those efforts, not as a replacement for them. Based on my results so far, this has earned a permanent spot in my routine, and I'll continue purchasing it. Highly recommended when paired with realistic lifestyle changes and consistency.

Love berberine!
I’ve been back and forth with this berberine because it took me so long to seem to adjust to it, but it seems to give me great steady energy and the BEST digestion of my entire life. I mean. I wake up and effortlessly use the bathroom. I eat breakfast, bathroom. Dinner, bathroom. Not in a bad way either. In a, wow my digestion works well and I never feel bloated or backed up anymore. It took my body a bit to adjust, and I definitely had to ease onto the product and figure out how to take it to work for me and not against me. Also, usually over the winters I gain 10+ lbs. I’m not even sure why. Less moving. More calorie dense foods and food cravings I guess. But this winter I only gained 5 lbs and I really think it’s because this product helped alot with curbing my appetite and made binge eating less appealing.

If you are insulin resistant run--don't walk, run--to order this (of course check with your doctor, etc.)
This has been a miracle drug to the person for whom I purchased it because they are insulin resistant (apparently many people are who do not know it). The person lost an incredible amount of weight as a direct result of taking this version of berberine. The only side effect seems to be a more active bowel movement schedule. Not diarrhea, just more and looser BMs. If you are having an insulin resistance problem i.e. you can't lose weight no matter how much you exercise and cut calories you should consider looking into whether you are insulin resistant and taking berberine. Look up the studies comparing prescription Metformin to berberine and you'll see that berberine is literally just as effective but without side effects. Don't believe me, look it up yourself. And it seems this particular brand and dosage works as claimed whereas many others do not. I appreciate the "Amazon's Choice" endorsement of this and other supplements as they cut through the morass of ineffective versions of supplements. The person who is taking this was considering Metformin. According the U.S. government--the National Institutes of Health--berberine does everything Metformin does but without side effects. And as far as I can tell, that is absolutely the case. I am loathe to endorse any product as a weight loss drug because I have never seen one that worked without concomitant harm of some sort. But this one absolutely is a weight loss drug if--and it's a big IF--you are insulin resistant (borderline type 2 diabetic) and considering taking Metformin. In the case I am witnessing (it's been about 90 days--30 days on, 30 days off, 30 days on--there is no question that berberine has radically treated insulin resistance. When the person was off, appetite was high, weight loss stopped, tiredness returned, etc. On berberine (this brand and dosage in particular) the person has lost weight, reduced appetite, increased energy, improved muscle tone, complexion, etc.--all the stuff that the imbalanced blood sugar levels were affecting. Could not give this a higher recommendation.

Honest Review
I ordered this hoping for a natural alternative to replace a pharmaceutical brand to help lower blood sugar. I will say I have not recorded the lowering of blood sugar. I did want to mention potential side effects I think you could possibly eliminate if you are mindful of what you are taking it with. I noticed when I took this product with any of my other supplements such as nutrafol or cortisol calm, I felt very tipsy a feeling of being high and drunk, very out of it. When I took it with just food, I did not have that feeling. The one thing I am trying to pinpoint is some inflammation I think it may be causing in my intestines that is causing back pain. I did a test and stopped taking and after 4 days pain was gone. I started again two days ago and now it’s back. Very disappointed my body does not like it. I do think it’s worth a try for a natural alternative. I did not write this to discouraging others from buying, but to be mindful of how and when you take it. I do feel it’s a great alternative and worth trying.

The Supplement That Finally Brought My Blood Sugar Back to Earth
This was recommended to me by both an MD and an acupuncturist, and honestly, I’m grateful they did. Berberine works on some of the same pathways as metformin — AMPK activation, blood sugar regulation, liver and gut glucose handling — all that science‑y stuff that makes your body behave. Now for the Donna part. I cannot take metformin. I get what they lovingly call disaster pants. Absolutely not. Hard pass. My blood sugar has been out of control for months — and I mean out of control. My Libre graph looked like my glucose was trying to reach the International Space Station. Just living up in the 300s like it pays rent there. Two weeks after taking two capsules twice a day with meals, my blood sugar dropped to 159. Is it perfect? No. Is it in the green? YES. And after months of chaos, that feels like a miracle. I’m not taking anything else — just eating more often (turns out not eating enough was part of my problem) and keeping carbs low. I can see the difference Berberine is making. Literally. On the graph. Approximately one week later, be generous and say two weeks I'm down in the green 167!! That is amazing! I struggled for months with extremely high blood sugar as shown on the graph. I'm on a roll! And the best part? No side effects. None. Zero. My stomach is finally living its best life. Also, who knew metformin can deplete B12? I sure didn’t. I was taking B12 shots — and let me tell you, that needle is not small. It’s the kind of needle that makes you rethink your life choices. I don’t need them anymore. My levels are holding steady without them, and I am thrilled. Berberine is working beautifully for me. It’s gentle, effective, and doesn’t come with any drama. Just steady improvement and a whole lot of relief.

Changed formulation without notice. Poor product. Sneaky tactic.
DIFFERENT,LOW QUALITY, BIOENGINEERED FORMULATION This is not the same formulation. This is no longer a natural product. The active ingredient (barberry root) has been cut by more than half and replaced by phytoestrogens; high omega 6 fillers; and a diluted, opaque, commodified, and bioengineered phantom product far from actual barberry. First I noticed the color of the pill on this reorder was different. Then I noticed that I didn’t feel the immediate effect. (I have been taking this for the last few years. I use it moderately and it’s been highly effective.) That’s when I compared bottles and realized this was an entirely different formulation. (See pics: original excellent high potency extract formulation is on left; what you get now is on the right). DANGEROUS LACK OF TRANSPARENCY I ordered this from my recurring order history. That means this was not posted on Amazon as the new product that it actually is. They slid it in the former product’s slot as if it were always this way. This means the new lesser formulation gets the high rating of the prior, and it also means people like me on reorder get something different *without warning*. Deceptive and dangerous. ACTION ITEMS I do not appreciate the lack of transparency nor the poorer quality product. This WILL be returned. Thorne has lost a loyal long-standing customer. And I have suggested to Amazon that they do the right thing and discontinue the old product record and clarify that this is a different product altogether! If you’re reading this, I suggest you do the same. UPDATE Amazon refunded me without issue. They are pretty good with that and no complaints there. The product listing however has not been updated and a glance of other online suppliers & recent reviews shows the same issue. I conclude then it is Thorne pushing a revised product w/o notice even to the distributors. If you are reading this and also dissatisfied by the inferior product and shady lack of transparency, I suggest you also insist on refund for this product. Money talks. Amazon & Thorne will listen when it hurts their bottom line.
