User Reviews for berberine

Also have seen a drop in blood sugar and a1c... I do not use metformin anymore...

My husband is on metformin and glimepride for type II diabetes. At his last checkup, his doctor was absolutely astounded at his A1C and lowered blood sugar. He has reduced his metformin and looks like we will stop using the metformin.

I use Berberine to lower my sugar levels. It works great and has no side effects like Metformin and works much better.

500 mg three times a day controls blood sugar. I stopped using Metforman as it produced little or no effect on controlling my blood sugar. No spiting, sweating, just nice effects.

My blood pressure was constantly very high, even with meds. When my med was increased, it slowed my heart down too much. I was having serious problems because I could not tolerate most BP meds. I started taking Berberine, and my blood pressure dropped so low that I had to skip my regular BP med. (And my heart rate was okay.) So far I have not noticed any side effects, but a big problem with my BP med was increased appetite, hair loss, and more. With a little more tweaking of the Berberine I should not have to take BP meds anymore. No more increased appetite, and hopefully my hair will stop thinning!Read More Read Less

I had low gfr (49) meaning my kidney was functioning poorly. Took 200 mg Vital Nutrients brand for 60 days and my gfr raised to normal >59.

A pharmacist in Vietnam advised me to take Antesik, a local Berberine-based medication, for indigestion. I took less than the recommended dosage over two days and woke up both nights with an extremely rapid heart rate which took several hours to slow down. This has never happened to me before and it was frightening. I see that this medication is used to treat heart disease but it seemed to cause heart problems for me! My stomach does feel better though. I would like to know if this is a recognized side effect of Berberine.Read More Read Less
