THORNE Berberine - Dual Action Formula with Phytosome Plus Botanical Extract - Support Heart Health, Immune System, Healthy GI, Cholesterol* - Gluten-Free, Dairy-Free - 60 Capsules - 30 Servings

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.)

The best brand of this product for me personally. I’ve tried other brands that did not work at all for the intended purpose. I’m completely satisfied that this brand is well worth the investment. If you are seeking to use Berberine to improve and impact your health and wellness, I would highly recommend Thorne brand.

I love this product. Helps me regulate my blood sugar levels. Cannot take Metformin.It works better for me. Only side effect for me is muscle cramps which I immediately eliminate by drinking apple cider vinegar and water.

appears to control glucose better

While this is a great supplement with many benefits, it caused changes in bowel movements for me, including constipation. I tried altering the dosage, but that didn't help. I'm not giving up on the supplement, but will have to make other adjustments to help my digestive system cope with the berberine.UPDATE: I ended up purchasing the other version of Thorne's berberine supplement -- the one with 200mg per capsule. This has made a big difference for me. Berberine works well for my health issues, but I simply need less of it. I also have an issue with iron absorption and low iron -- which can be a problem if too much berberine is consumed. So the lower dosage is much easier and better for me to control in terms of digestive and iron-lowering side effects.

DIFFERENT,LOW QUALITY, BIOENGINEERED FORMULATIONThis 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 TRANSPARENCYI 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 ITEMSI 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.UPDATEAmazon 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.
