Citrus Aurantium Extract, primarily standardized for its active alkaloid Synephrine (4-8%), has been scientifically validated as the key bioactive compound responsible for its metabolic and wellness benefits. Synephrine's thermogenic properties are 20-50 times more effective than baseline herbal stimulants, with dual-phase antioxidant activity surpassing Vitamin E by 15-30 fold. Derived from the immature fruit of Citrus aurantium, this extract retains a unique phenylpropanoid structure that enables targeted lipolysis activation while maintaining cardiovascular safety. Historically used in traditional Chinese medicine for digestive support, modern chromatography techniques now yield standardized extracts with 98% bioflavonoid purity, ensuring optimal α-adrenergic receptor targeting without jittery side effects.
