Synephrine is a naturally occurring compound found in the bitter orange fruit, scientifically known as Citrus aurantium. It is often used as a dietary supplement for weight loss and energy enhancement. Synephrine is structurally similar to ephedrine, a stimulant, but is considered to have milder effects on the body. Research on synephrine suggests it may help increase metabolism and promote fat oxidation. However, its safety and effectiveness are still debated among health professionals. Users should be cautious, especially if they have underlying health conditions or are taking other medications, as synephrine can interact with certain drugs.
