In a lengthy profile in the latest issue of Rolling Stone, Wilson claims the water, which the company he’s working with sells for $3 a bottle, caused his brain to recover from what could have been a serious injury.

“I banged my head during the Packers game in the playoffs, and the next day I was fine,” Wilson said. “It was the water.”

Wilson insists that the Recovery Water “works well,” and that a teammate used the water to heal a knee injury. And if that makes Recovery Water sound more like a scam than a miracle cure, well, Wilson admits he can’t prove that it works.

“Well, we’re not saying we have real medical proof,” Wilson said.
