The Question

“I want to try berberine for a possible diabetic. In humans, it acts just about like metformin and is less toxic, so I would like to avoid drugs for this rescue by using it. I realize there is a lack of research due to a probable lack of interest and possible revenue.“ – Betty

Hi Betty,

I truly appreciate your thoughtful approach to helping this rescue, especially when you hope to choose what feels like a natural option. In human medicine, berberine has attracted interest for its glucose-lowering effects, but as you mentioned, research in cats is limited or non-existent. The feline liver processes compounds differently, and without controlled studies, we cannot predict how berberine is absorbed, how long it persists in the body, or whether it interacts with other conditions. This turns its use into guesswork, much like trying to navigate a dark room without knowing where the furniture is placed, and the risks can outweigh the hoped-for benefits.

In contrast, feline diabetes is well studied and very treatable when addressed early. Obtaining proper diagnostics allows us to confirm whether diabetes is truly present and to tailor a plan that protects the cat from complications such as ketoacidosis. Metformin is generally not used in cats because their disease responds far more reliably to insulin therapy along with nutritional management that supports glucose regulation. In fact, many cats living with Type 2 diabetes have a real chance of remission when they receive the right nutritional support. It is one of the most encouraging aspects of this condition because the body often responds beautifully when we align diet with natural feline metabolism.

Kind regards,

– Dr. Paola
