Positive experiences
“I started berberine and inositol, and began having energy that I did not have before. Somehow, my recovery after working out wasn't as long either.”
“Hard to tell, my glucose levels were always good anyway. They are a bit better now. I am just taking 500mg daily (instant release).”
“I found Berberine. It is 'essentially' the natural form of Metformin. It works great for me when I'm doing a cut and help with fasting.”
“berberine helped with my blood sugar somewhat but nothing would make my blood pressure budge.”
“Berberine: together with lemon leaf. Result: I sleep like I have never slept before.”
“I take one after every meal and it really helps with not feeling like that since it does a whole bunch of beneficial things for blood sugar/insulin.”
Negative and mixed experiences
“I find it makes a huge difference in keeping my BG stable. I've tested a dozen products/ingredients and berberine/lipo berberine/DHB all work fantastically.”
“I actually tried Berberine which is an OTC supplement with similar effects and I almost passed out, my insulin dropped so much I couldn’t think or focus clearly at all.”
“I've had great results from using berberine, it's a powerful supplement that works in more than one pathway.”
“I started berberine for high blood sugar but quickly noticed mood and energy enhancing effects from it. I've been taking 500 mg daily...I experienced the worst gastrointestinal issues ever, pure yellow diarrhea and smelly piss.”
“I feel really really happy, I keep dancing lol. Probably placebo, but I didn't expect feel good mood benefits!”
“If I take it before a high carb meal, I don’t feel sleepy afterwards (which I assume means my blood sugar isn’t spiking as much).”
