Synephrine 用于 Fat Oxidation Enhancement

B

Systematic review of 20 studies found p-synephrine at 25-100 mg/day increases resting metabolic rate by 65-183 kcal/day. It is a selective beta-3 agonist without significant cardiovascular stimulation. A 12-week RCT (n=70) found greater weight loss with synephrine plus hesperidin versus placebo.
