Coconut water is by far a better drink then Vitamin water, or Gatorade, or any of those "replenish" drinks. It's content is almost of perfect mix and balance of minerals, amino acids, fatty acids, enzymes vitamins and other nutrients.
Some of the benefits of coconut water are:
Coconut water is a very refreshing drink to beat tropical summer thirst. Its liquid is packed with simple sugars, electrolytes, and minerals to replenish dehydration conditions inside the human body.
Research studies suggest that cytokinins (e.g., kinetin and trans-zeatin) in coconut water found to have significant anti-ageing, anti-carcinogenic, and anti-thrombotic (anti-clot formation) effects.
Coconut water has been generally offered to patients with diarrhea in many tropic regions to replace the fluid loss from the gastrointestinal tract and to reduce the need for hospitalisation. The osmolarity of tender coconut water is slightly greater than that of a recommended ORS (Oral Rehydration Therapy) solution. Presence of other biological constituents like amino acids, enzymes, minerals, and fatty acids may account for this higher osmolarity. Nonetheless, unlike the ORS, its water is very low in sodium and chlorides, but rich in sugars and amino acids. This well-balanced fluid composition, along with much-needed calories, would be an ideal drink instead of any other kind of soft drink beverages available in the markets to correct dehydration conditions.
