Stars are going loco for the coco – coconut water, that is.
From Madonna to Penn Badgley, celebs have been spotted sipping the low-cal beverage as they beat the summer heat. And despite its A-list following, the drink is pretty low-key: coconut water is the liquid found in green coconuts.
The Material Girl invested in Vita Coco because it’s an independent company. “The fact that they are saying ‘no’ to everyone who wants them is pretty cool,” her manager tells the New York Post. “You want to go to the party that no one else is invited to.”
Coconut water is a million dollar market, thanks to other brands like Zico and O.N.E., which is a favorite of Rihanna, Kim Kardashian, Anne Hathaway, Nicole Scherzinger, Nick Cannon and Brooke Shields, to name a few. The beverage banks in the range of $40 to $60 million annually – although the category has yet to compete with billion-dollar drink brands like Red Bull, says Jeffrey Klineman, editor of Bevnet.com, an online publication that reviews nonalcoholic beverages.
Sims, who is the face of Zico, says she turns to the beverage for healthy hydration, which she explained at the unveiling of her Zico billboard in N.Y.C.
Said Sims: “You’ll never have to eat a banana because [coconut water’s] very high in potassium!”
