Mango is rich in a variety of phytochemicals and nutrients. The fruit pulp is high in prebiotic dietary fiber, vitamin C, polyphenols and provitamin A carotenoids.

Mango contains essential vitamins and dietary minerals. The antioxidant vitamins A, C and E comprise 25%, 76% and 9% of the Dietary Reference Intake (DRI) in a 165 grams (5.8 oz) serving. Vitamin B6 (pyridoxine, 11% DRI), vitamin K (9% DRI), other B vitaminsessential nutrients such as potassium, copper and 17 amino acids are at good levels. Mango peel and pulp contain other phytonutrients, such as the pigment antioxidants - carotenoids and polyphenols - and omega-3 and -6 polyunsaturated fatty acids. and

Mango peel contains pigments that may have antioxidant properties, including carotenoids, such as the provitamin A compound, beta-carotene, lutein and alpha-carotene, polyphenols such as quercetin, kaempferol, gallic acid, caffeic acid, catechins, tannins, and the unique mango xanthone, mangiferin, any of which may counteract free radicals in various disease processes as revealed in preliminary research. Phytochemical and nutrient content appears to vary across mango species. Up to 25 different carotenoids have been isolated from mango pulp, the densest of which was beta-carotene, which accounts for the yellow-orange pigmentation of most mango species. Peel and leaves also have significant polyphenol content, including xanthones, mangiferin and gallic acid.
