Before there was Russell Wilson and "Recovery Water," there was Tom Brady and "NeuroSafe."

The Patriots quarterback once attached his name to an anti-concussion product that went out of business four years ago, Pro Football Talk reported.

Russell Wilson Says Recovery Water Helped Prevent Concussion, Not Made One Go Away

NeuroSafe alleged that it "protects your brain from the consequences of sports-related traumatic brain injury," according to PFT.

An ad for the product quoted Brady as saying, "NeuroSafe makes me feel comfortable that if I get a concussion I can recover faster and more fully. There is no other solution on the market today that can do what NeuroSafe does. It's that extra level of protection that gives me comfort when I'm out on the field."

Russell Wilson Credibility Questioned After Hawking Anti-Concussion Product

Wilson recently made similar claims about Reliant Recovery Water in an interview with Rolling Stone magazine, but backtracked after other media outlets jumped on his comments.

"I banged my head during the Packers game in the playoffs, and the next day I was fine," says Wilson. "It was the water. ... I know it works."

A day after that comment became public, Wilson clarified his remarks.

"I didn't have a head injury, but what I was trying to say is I think it helped prevent it," he said, according to ESPN. "I think your brain consists of like 75, 80 percent water, so I think that just being hydrated, drinking the recovery water really does help."

Apparently, the product Brady endorsed did not do what it claimed because it went out of business, PFT reports. NeuroSafe no longer has a website; it has a Facebook account, but its page has not been updated since December, 2011.

PFT chastised both Brady and Wilson for endorsing products it says don't deliver on what they claim.

"There's a good reason that products like this go out of business: They don't work. They're scams. They're snake oil," the site says. "And they're dangerous because they mislead people about proper protocols for prevention of brain injuries. It doesn't speak well for Wilson or Brady that they're willing to lend their names to such products to make a buck."
