BulkSupplements.com Barberry Extract Powder - Berberine Supplement, from Barberry Root & Bark - Soy Free - 500mg per Serving, Pack of 5 (5 Kilograms - 11 lbs)

I bought Barberry Extract as a more-whole form of Berberine. Barberry Extract is a less-purified thing. Yes, there's some Berberine in there too, but also some other stuff. Generally you get better effects from keeping the complexity of an entire plant (e.g. Turmeric is more powerful than isolated Curcumin), so I actually prefer taking Berberine this way.However! It turns out that Berberine inhibits the PDE5 enzyme at the mRNA level (less is transcripted to be synthesized). For comparison, traditional PDE5 inhibitors act on the free-floating, already-synthesized enzyme. Berberine can be stacked with traditional PDE5 inhibitors for some extra kick.PDE5 is an enzyme that eats Nitric Oxide, which is a signaling molecule that causes blood vessels to dilate. For good blood vessel function, you want more Nitric Oxide in the body and you want it to stay around longer. To get more Nitric Oxide, eat Beet Roots or Arugula (or supplements based on either).While it should be obvious why more blood flow is a good thing (for both sexes), some men focus on suppressing PDE5 and boosting NO for certain... purposes. Ask your parents when you're older.I initially tried Barberry Extract as a way of troubleshooting my weight because of the blood sugar effects. Honestly Barberry Extract caused no change to my weight, but the increased blood flow was something I definitely noticed after a few days of consistent supplementation.

I used this for helping to control my blood sugar. I mixed it with ginger powder and Milk Thistle and put it in a smoothie. I was also dieting on low carb foods. I lost weight and felt great and this barberry powder had a lot to do with it, I think.

Good product would order again

I use this to keep my blood sugar low, and will make a bunch of capsules, cheaper than buying them. The only problem I have is, it's a bit messy and sticks to my fingers, even though it's a powder. It's just as effective as buying the capsules.

Good quality product, TERRIBLE PACKAGING. Once opened the zip-lock-type bag will not seal...

I love that this brand is no nonsense, additives, or fillers. Every product I've bought from them is pure and actually affordable. Definitely a huge fan, and will continue to buy as long as they keep their pricing the same.

This is second time I bought this product. First time (Jan 2024) I bought a smaller package (250g) to check it out. I knew the taste was expected to be bitter. It was, but tolerably so. It dissolved well.So when the package finished I ordered a 1kg package (Aug 2024). I noticed a difference as soon as I opened the package. The powder was much more finely ground.It turned out that the taste was also different, much more bitter. I can still drink it, but a lot less pleasant.However, the main reason why I am rating it so low is that it does not dissolve fully even in warm water. Vigorous swirling with a spoon does not help either.So product seem to have changed between Jan and Aug.

I switched to this powder form from capsules. The whole time I was taking the capsules my stomach was ON FIRE! My theory is that the capsules float to the top of your stomach and that is what causes the irritation where the esophagus enters the stomach. I have had ZERO pain since switching to powder! Thank goodness, because berberine (barberry extract is exactly the same thing) was really helping me.
