Citrus aurantium extract for weight loss by Natrol

WEIGHT LOSS PILL TYPE: Thermogenic agent. Citrus aurantium is derived from the citrus rinds of the bitter orange while the fruit is still green.

SOLD AS: Capsules, typically 250 mg.

BACKGROUND/RESEARCH: Citrus aurantium has long been used in traditional Chinese medicine to treat indigestion and to promote circulation and liver health. Much of the evidence about the weight-loss ability of citrus aurantium is anecdotal and has been passed down from generation to generation in various cultures. A scientific study conducted in 1999 looked at the’ anti-obesity effects of an extract of citrus aurantium in rats. The researchers did find that the extract “significantly reduced food intake and body weight gain” in the rats. Studies in people, however, are lacking.

WHAT IS IT SUPPOSED TO DO; Citrus aurantium is a rich source of flavonoids, vitamins A, B, and C, and several alkaloids that have the ability to break down fat and raise resting metabolism levels. Two of these alkaloids are synephrine and nobiletin. Small amounts of synephrine can increase energy and improve digestion, and nobiletin protects against some cancers and regulates secretions in the ‘intestinal tract. A combination of citrus aurantium and moderate physical activity is reported to be very effective in weight loss.

HOW TO TAKE IT: A typical dosage of citrus aurantium is generally 1 capsule per day, with food.

SIDE EFFECTS: Citrus aurantium has no known side effects, although studies are limited. Unlike some other thermogenic substances, such as ephedra (ephedrine), citrus aurantium supposedly does not increase heart rate or blood pressure or cause agitation.

PRECAUTIONS: Although no studies have shown it to be harmful to pregnant or breast-feeding women, it is best to avoid this supplement during pregnancy and lactation.
