Coconut water has been touted as the new sports drink. A natural alternative to beverages like VitaminWater and Powerade, the electrolyte-concentrated juice from green coconuts has been branded and bottled by multiple companies. ConsumerLab.com set out to discover if these drinks actually deliver. Their results found that it depends on the brand.
In their Coconut Waters Review, researchers tested three leading brands: O.N.E., Vita Coco and Zico. Testing the potassium, magnesium, sodium and sugar content of all three coconut waters, they discovered that only one of the three (Zico) contained the amount listed for all four ingredients.
Sugar and potassium amounts matched the labels for all of the waters. However, sodium and magnesium amounts were off for Vita Coco (82% lower) and O.N.E. (35% lower). It’s important to note that sodium and magnesium are the two nutrients central to hydration. With the hydration ability of coconut water being one of its main selling points, buyers should beware they may not be getting what they’re paying for.
The truth of the matter is, for average people doing average exercise—water is all that’s needed to the body post-workout. If you drink coconut water, purely for the taste and some added nutritional benefits, you don’t really have much to worry about.
