Berberine is a potent tool for controlling blood glucose and requires caution as it can deprive the brain of its preferred fuel source.

“I would say, be very cautious about ingesting Berberine on an empty stomach, or if you are in a low carbohydrate diet, unless you really know what you're doing and you have a medical professional to kind of guide you through that.”

“when I took berberine and did not ingest large amounts of simple sugars or carbohydrates along with it I experienced profound hypoglycemia I felt like complete garbage for about eight hours and I had one of the worst headaches of my life”

“one thing I noticed was that if I took berberine and I did not ingest a profound number of carbohydrates very soon afterwards I got brutal headaches I think I was hypoglycemic I didn't measure it but I just felt I had headaches I didn't feel good”

“These substances like bourberine are very, very potent. And you need to take them seriously. There is yet another tool for controlling sugar cravings and the neural circuits that regulate sugar”
