Commonly referred to as bitter orange, this plant contains the active ingredient synephrine. Synephrine is similar chemically to ephedrine, yet it does not raise heart rate and blood pressure as ephedrine can. Synephrine mimics the actions of norepinephrine. This neurohormone works to increase metabolic rates. Synephrine also stimulates receptors on fat cells that increase lipolysis the release of fat from the fat cells to be burned for fuel. In addition, synephrine has even been found to decrease appetite.
This amino acid is readily converted in the body to nitric oxide. NO is responsible for countless processes in the body, including the dilation of blood vessels the most critical to bodybuilders. This widening of the blood vessels allows more blood to flow through and reach tissues such as muscle fibers, which enables more oxygen, nutrients, anabolic hormones and supplements to reach them. NO also appears to have its own ability to encourage fat burning. French scientists have discovered that NO enhances lipolysis, making more bodyfat available to be burned as fuel.

Taking fat burners such as Citrus aurantium with arginine can help deliver more of their ingredients to your fat cells, muscles and other critical tissues for a much greater effect. Take a Citrus aurantium extract that is standardized to provide 10-20 milligrams of synephrine three times per day, along with 3-5 grams of arginine in the form of either L-arginine, arginine alpha-ketoglutarate, arginine ketoisocaproate, arginine malate or arginine ethyl ester. The best times to take these are in the morning, afternoon and 30-60 minutes before workouts.
