Blood sugar levels do not rise
Verified Purchase
I take it after dinner. Usually after dinner I would pass out and sleep on the sofa. But after I take this berberine and eat, I don't feel sleepy. My weight hasn't changed the next day, so I think it's keeping my blood sugar levels in check.

Like the weight loss shot
Verified Purchase
One in the morning with food or after food and you don't feel like eating anything. Lowers sugar levels so you don't feel like eating sweets. Take seven from half a meal. Be careful, it can make you nauseous at first, let your body get used to one pill with food and then see the reaction.

Sugar control
Verified Purchase
I've been taking berberine for some time now. Overall, my impressions are positive: I feel good, and I haven't noticed any discomfort while taking it. It's convenient that it can be used as additional support for sugar and metabolism control. Of course, you shouldn't expect results after just a couple of capsules, but with regular use, the effects are felt gradually. Overall, I'm happy with the supplement.

Contains patented extract.
Verified Purchase
Great quality berberine formula—love that it includes Berbevis® for better absorption along with added plant extracts. I’ve noticed improved energy and overall balance, especially with blood sugar and metabolism support. Clean, effective, and easy to take. No upset stomach or after taste —definitely a supplement I’d keep using!

Blood sugar control
Verified Purchase
I'm going to try berberine as a last resort before getting an obesity injection. I took it during my period, so I think I'll have to wait and see if my appetite changes, but my bowel movements are better, my anorexia has decreased, and my cravings for food have also decreased.

Barberine journey
Verified Purchase
I started taking Barberine with this little jar, it was a good way for me to explore if it worth it for me. It is a very smzll size package, but perfect enoght to trial it. Barberine has multiple benefits to support overall health and ensure healthy aging. Instructions suggest a dose of 2 capsules that will allow you to take it for 5 days. Overall it was a good quality barberine and I purchased a larger package after this trial.

Berberine, also known as berberine, is a natural alkaloid extracted from various plants and has a long history in Ayurvedic medicine. It activates AMPK, a key enzyme in the body. Its antimicrobial properties help balance the gut microbiome and may treat certain gastrointestinal infections. However, berberine may interact with certain medications (particularly those for diabetes and heart disease), so caution is advised before use.
