Product Description


Bitter orange (citrus aurantium) is used widely to make commercial marmalade.  It has been also been used for thousands of years in Chinese medicine and by natives of the Amazon.  The peel (which is used in the tincture) has anti-inflammatory, anti-bacterial, and anti-fungal properties.  It also contains neurotransmitters p-synephrine alkaloids, octopamine, and tetrahydrobiopterin.   The immature form of the fruit has higher levels of BH4, a key component of metabolic cycles frequently compromised in individuals with polymorphisms on the MTHFR gene and genes related to methylation, detoxification, and sulfation.  It appears to support mitochondrial function by increasing energy production in the body and also appears to improve insulin resistance.  It is also reported to be calming to the digestive tract and can help to promote sleep.*  Our Bitter Orange is a high quality product made in small batches in Hawaii.

When individuals on the autism spectrum have intestinal dysbiosis, pathogenic microbes, yeasts and other pathogens living in the intestinal tract frequently overgrow and produce large amounts of ammonia.  BH4 detoxifies ammonia - and if most of the Bh$ is depleted detoxifying, then it is not available for other processes in the body such as creating neurotransmitters and methyl donors that switch genes on and off, and reduces the production of important antioxidants such as glutathione and super oxide dismutase.  Bitter orange may be a valuable addition to consider enhancing a methylation support protocol.

In studies it has been shown to increase levels of reduced glutathione, the catalase enzyme and has been shown to contribute to weight loss in numerous studies.  Note that this form of synephrine binds to specific beta 3 Andrenergic sites but does not bind to the beta 1 and 2 adrenergic sites (which can increase risk of heart attack and stroke).  It contains the same form of p-synephrine found in mandarin oranges and clementines - so consuming a glass of orange juice provides about 25 mg of p-synephrine. 

Bitter orange is frequently combined with weight reducing supplements that include large amounts of caffeine.  In all studies with bitter orange used exclusively with no other additives, it appears to be completely safe.  However, because it contains neurotransmitters it should not be taken in combination with any prescription drugs designed to modify brain chemistry.
