What is Citrus Aurantium (also known as Bitter Orange)?
According to noted sports nutrition expert, Alan Shugarman, M.S., R.D., citrus aurantium is a citrus fruit that contains synephrine, N-methyltyramine, hordenine, tyramine, and octopamine. The actives in bitter orange increase metabolism by stimulating the beta-3 receptors while not directly stimulating beta 1 and 2 like ephedrine. Compared to ephedrine Citrus aurantium has little effect on heart rate and blood pressure. AdvantraZ™ is a brand of Citrus aurantium patented for thermogenesis (heat production), reducing body weight, and increasing lean muscle. The recommended dose is between 60 – 120 mg per day in two to three doses. Citrus aurantium is often combined with caffeine to increase its effects on metabolism and calorie burning. You will often find Citrus aurantium in ephedrine free weight loss supplements. While research on the Bitter Orange for weight loss is not abudant the product does show promise and more research is planned in the future.
