Bitter Orange Supplements for Weight Loss

‘Citrus aurantium’ or more commonly known as Bitter orange or Seville orange, is a citrus fruit native to Southeast Asia. Bitter orange extract contains an active ingredient called p-synephrine, that is used to make various dietary supplements that help with weight loss, skin care and brain health. (1)  In 2004, supplements containing ‘p-synephrine extracts’ were banned by the U.S. Food and Drug Administration (FDA), due to its structural similarity to ‘ephedrine’, claiming that it increased heart rate, raised blood pressure and elevated the risk of causing strokes. However, several recent studies have claimed that bitter orange extracts do not result in cardiovascular effects or behave as stimulants when consumed within prescribed doses.

Traditional uses of Citrus aurantium

In traditional Chinese medicine, the fruit and the dried peel of Citrus aurantium, has been used for centuries, owing to its potent health benefits, for the treatment of indigestion, diarrhoea, dysentery and constipation. It has also been used as sedatives in South American folk medicine to treat insomnia, anxiety, and epilepsy. (2)

‘Seville oranges’ got its name from Seville, Spain where it has been grown for over 800 years and traditionally used in the preparation of various food products such as marmalades, syrups, liqueurs, and juices. The fruit is also valued for their oil content and used as flavouring agents and in the preparation of perfumes.
