Mangoes contain vitamin C and beta-carotene, gallic acid and their larger polymers gallo tannins, that have been linked to anti-cancer and anti-inflammatory activities in previous in vitro and in vivo studies. 

The absorption, metabolism, and excretion of mango galloyl derivatives have not previously been investigated in humans. 

 In this human pilot trial published in the journal of Molecular Nutrition & Food Research, 11 healthy volunteers between the ages of 21 and 38 years old consumed 400g/day of mango-pulp for 10 days, with blood and urine samples taken on days one and 10 of the study following mango consumption.
