Berberine HCl 500mg, 97% Purity, Metabolic, 60 Capsules | Metabolism Supplement, AMPK Activator, Appetite + Hormonal Balance Support, 97% Purity, Third-Party Tested

I’ve only been using it for two days so if I build up a tolerance to this stuff too quickly this review may be updated in the future, but so far I’m very happy with it. I took my first capsule in the morning on an empty stomach and it took about an hour and a half to two hours to hit, but when it did the effects were very noticeable. First of all, my appetite was reduced to like 20% of what it normally is and I spent most of my day at work wanting almost no food. After about five hours I finally started to get a little hungry so I ordered one of my favorite things (bacon cheeseburger patty melt on sourdough with extra crispy hash browns! Yummy!), something I could normally inhale in ten minutes without exercising ALL my willpower, and I found that after eating less than a quarter of it I felt full and satisfied, like I’d just gone on a binge! Pleased, I snuck a few more tiny bites of my hash browns, like really tiny bites, and easily put away the rest in the fridge. I didn’t really get hungry again until about 8pm so I took a second pill and made myself a medium sized bowl of Korean style chicken and rice, ate less than a third of what I normally would, and again, that full satisfied feeling after such small amount of food soon followed. I’m really happy with the results and I hope it keeps working. Some cons, it gives me a little bit of a headache and a stomach ache, but those side effects are supposed to go away after you get more used to it so I’m staying hopeful. Usually I have fairly good discipline and self control with my eating so I hope this is my ticket to help making it an almost effortless endeavor. Update: Had to lower it to 4 stars from my 5 because the resulting headaches have gotten worse and today it made me very drowsy. I also bought some Berberine gummies that are supposed to have 100 mgs more per serving than these capsules but the effects are way milder! So I can only assume that either there is way more than just 500 mgs in these pills or the way it’s formulated is just too intense. These pills definitely work! Maybe too well. Second update: Rescinding my four stars and giving back it's original five! Now that I'm more used to berberine the side effects like headaches and drowsiness are a lot better and sometimes barely noticeable. Where was this stuff hiding during my competitive modeling days?? Berberine is powerful and takes some getting used to. It helps to start small and slowly add more as you build up your tolerance. I suggest starting with some gummies of comparable strength to these pills and cutting them in half, or even fourths if you're super sensitive. As you get more used to this herb you can start gradually adding more mgs to your daily routine. I can handle a full 500 mg cap at once now. I don't question the efficacy of berberine at all. If you're like me it may work a little too well for you.

I do not give many reviews on supplements, but this Berberine is good and it works. You have to give it time to get in your system. Take it at least 15 minutes before you eat. I recommend with starting with one a day. It will curb your appetite. Eventually, if you can tolerate take twice daily before your meal. However, with any product, its not magic...have a balanced diet and exercise. It does help with food noise and decreases sugar cravings. Everyone is different...if interested just try it for yourself. I like it.

I take Berberine everyday for the health benefits. No digestive side effects and I only take one pill. I have used other Double Wood products with great results! They offer high quality at a decent price with lots of choices.

I had no side effects from this product at all. I took with food, easy to use and I stop eating around 4-5 and had no hunger pains. I like this one because there were no fillers.

Appears to be working according to my previous research. Highly recommend it.

My doctor prescribed it for my insulin resistance, and it has worked really well for me. It has kept my glucose spikes in check.

Been taking these for metabolic support. Capsules are easy to swallow and no weird aftertaste. Seems like solid purity based on how they hit. No stomach issues so far. Will keep using. Good price. No side effects.

Manufacturing practices seem to have deteriorated recently. I have been taking this Double Wood berberine supplement product for three years. Recently, however, two product issues are becoming all too common: 1) noteworthy amounts of loose berberine powder contaminates the surface of the capsules and inside of the bottle (i.e., capsules and inside of bottle covered with yellow powder); and 2) occasional capsules are crushed or defective apparently resulting in contamination of the entire contents of that bottle. It goes unsaid that the extremely bitter taste, even after cleaning the capsules, is very unpleasant.
