The biggest issue is its high potassium content. A single cup can contain around 600 milligrams of potassium, making coconut water considerably richer in this mineral than many other beverages. Drinking several servings every day could significantly increase your overall potassium intake.
This becomes more important for people with chronic kidney disease or reduced kidney function. When the kidneys cannot remove potassium efficiently, levels can rise in the blood. Very high potassium levels can affect muscles and, in severe cases, interfere with the heart’s normal rhythm.
