Vita Coco producer All Market Inc is facing a lawsuit in the US over claims that the coconut water doesn't deliver on its nutritional or health claims.

The lawsuit, filed on Monday (15 August), accuses Vita Coco of overstating the amount of electrolytes in the range and exaggerating its hydrating benefits. The case was filed by Florida lawyer, Stacey Fishbein on behalf of "all those similarly-situated", and was spurred by a study from ConsumerLab.com that tested the contents of Vita Coco.

The report found that Vita Coco contained "far fewer" electrolytes than claimed, with "considerably less" sodium and magnesium than the amounts listed on the product's nutrition labels.

Fishbein claims in the US District Court filing seen by just-drinks that the representations made by Vita Coco are "simply false" and are "no more hydrating than a standard sports drink". The lawsuit accuses the firm of deceiving consumers by "concealing the drinks' true nutrient levels".

Fishbein is seeking unspecified monetary damages from All Market, a corrective advertising campaign and an apology to consumers.

A spokesperson for Vita Coco, Arthur Gallego, told just-drinks: "Vita Coco coconut water is regularly analysed by Covance, an independent consumer lab, to ensure the nutrient levels stated on our labels are consistent with the amount in our coconut water.

"Variations in nutrients occur because Vita Coco is produced from fruit grown in various locations in Brazil and Southeast Asia," Gallego added. "Because coconuts from different regions can, like any natural produce, vary in nutritional content, there are minor fluctuations in the amount of nutrients found in each beverage unit."
