WORKS! A1C down

I have taken this for 6 months now. It has reduced my A1c and I feel less bloated when I eat. I have also lost some weight. I hope they bring this product back soon!

Berberine works!!!

Finally, something that really works for blood sugar. We have tried every blood sugar supplement available for over a year for my husband. Nothing lowered it until Berberine!! Thanks Dr. Whittaker and may God bless you!

Caution

This preparation of Berberine induces painful gastrointestinal problems with really bad diarrhea. It happened to me and to my colleague who also ordered this Berberine recently

In addition to berberine, i also take glucose essentials, bio active Q and cholesterol essentials. These combined have reduced my A1C to normal.The restful night formula has also been excellent.

Berberine Lowered My LDL's and Triglicerides

I take 1 capsule, 3 times a day and my cholesterol went from high to normal. After using berberine for over a year, my physician is impressed. Dr. Whitaker is the greatest!

Berberine user

I have been taking berberine to help control my blood sugar ever since Dr. Whitaker prescribed it while I was a patient at the Whitaker Wellness Institute. An excellent product.

"whatever you are doing, keep doing it."

After taking Berberine for 3 months my AIC, HDL and LDL levels improved significantly. My doctor said "whatever you are doing, keep doing it." The only changes I made was to start Berberine.
