The water is a filtered sap that’s drawn up from the roots and transported through the tree’s vascular system (its water and nutrient transport system), specifically the xylem tissue.

The coconut tree’s extensive root system, ranging from 1 to 5 metres deep, absorbs groundwater – with dissolved nutrients – from the surrounding soil. The absorbed water is then transported upwards through the trunk and branches and finally to the fruit.

The fruit retains this water, stored in the cavity of the coconut. The accumulated water, with its rich nutrients, provides food to the developing endosperm (white flesh).

Therefore, coconut water is neither rainwater nor seawater stored inside, but carefully filtered and nutrient-rich clear liquid formed by the tree itself.

About 95% of coconut water is simply water, making it an excellent hydrating fluid.
