It can serve as antioxidant
The metabolism in your cells produces unstable chemicals called free radicals. When under stress or after an injury, their production rises. Your body experiences oxidative stress when there are too many free radicals, which can harm your cells and increase your risk of disease.
Coconut water includes antioxidants [1], according to studies conducted on animals, which could aid free radicals to become harmless. In a study from 2012, coconut water was given to insulin-resistant rats consuming a high-fructose diet [2]. Free radical activity, blood pressure, lipid, and insulin levels all fell.
Another research from 2014 discovered that coconut water therapy significantly reduced oxidative stress in damaged rat livers compared to livers that did not get treatment.
A third study [3] from 2016 showed the benefits of coconut water extract on rats fed a high fat diet. It was not only able to reduce cholesterol markers, but it also showed antioxidant potency.
However, it is important to note that there are currently no studies involving humans and their antioxidant power, and each of the animal studies used different dosages and parameters.
