Synephrine is a naturally occurring substance that aids in burning fat. It is safe to take and been used in traditional Chinese medicine for hundreds of years.
It enhances the process of thermogensis, which is the process of heat production to help burn fat. Synephrine works in synergy with caffeine to further raise the body's metabolic rate during and after exercise.
Our synephrine HCL is extracted from bitter orange fruit and 98% pure.
