Like any loan, there's an interest to be paid. Every surge of alertness you feel after caffeine has borrowed from your body’s bank of energy, needs to be repaid as well. By stimulating the adrenal system, caffeine prompts the release of stress hormones like cortisol[3]. Over time, excessive caffeine consumption can strain the adrenals, leading to symptoms like fatigue and irritability, which coffee lovers might recognize as a "caffeine crash."
Real Berberine is a fantastic product. It lives up to everything that has been said in the advertising. I’ve only been taking it for ten days and I’m watching my glucose readings and my blood pressure readings going down to a healthy number. Something that my prescriptions haven’t been able to do. So very pleased.
