Citrus fruits have a naturally diverse composition, consisting primarily of water, carbohydrates, dietary fiber, organic acids, vitamins, minerals, and phenolic compounds. These compounds include flavonoids, whose concentration and profile may vary according to the species, variety, stage of ripeness, and growing conditions.

Bergamot is known for containing the flavonoids neoeriocitrin and neohesperidin. Bergavit® is obtained from the juice of bergamots cultivated in the coastal region of Calabria, Italy, and has a standardized concentration of 25% to 28% flavonoids.
