Received Accepted Published Abstract Bitter orange Citrus aurantium extract is widely used in dietary supplements for weight management and sports performance. Its primary protoalkaloid is p-synephrine. Most studies involving bitter orange extract and p-synephrine have used products with multiple ingredients. The current study assessed the thermogenic effects of p-synephrine alone and in conjunction with the flavonoids naringin and hesperidin in a double-blinded randomized placebo-controlled protocol with 10 subjects per treatment group. Resting metabolic rates RMR blood pressure heart rates and a self-reported rating scale were determined at baseline and 75 min after oral ingestion of the test products in V-8 juice. A decrease of 30 kcal occurred in the placebo control relative to baseline. The group receiving p-synephrine 50 mg alone exhibited a 65 kcal increase in RMR as compared to the placebo group. The .
