Are you ready for another fitness water brand backed by celebrities? 

At a press conference yesterday, Mark Wahlberg and Sean "Diddy" Combs announced a partnership with former Fiji Water CEO John Cochran to launch AQUAhydrate, a “fitness and wellness water brand” that's devoid of "the sugar and calories found in traditional sports drinks or vitamin enhanced beverages.”

As Wahlberg explains, he first discovered the water while training for his film "The Fighter," saying that it helped his body achieve balance after his high-intensity workouts. He then convinced Combs, a longtime friend, to sample the beverage and help back the company. 

"When I tasted this water, I fell in love with this water. It was that simple," said Combs. "I really do not like the taste of the majority of waters that are on the market. I am just looking for something that makes me feel good and tastes good."

So, is this brand of water really any better than the stuff that comes out of the tap? If you're simply thirsty, then no. If you're someone who regularly enjoys high-intensity workouts or sports, then there may be some benefit. According to the marketing spiel, AQUAhydrate provides you with "high quality alkalized water with a significant amount of electrolytes." 

 "We all strive to do the best we can for our bodies but sometimes schedules, stress and other factors get in the way," said Wahlberg in a statement. "AQUAhydrate helps me achieve the balance my body needs, no matter what.  I enjoy being involved in every aspect of the AQUAhydrate brand, and I'm looking forward to a very successful partnership."

A 1999 medical study on "Water and electrolyte requirements for exercise" found that commercial beverages containing electrolytes were a valid option for athletes training 90 minutes or more, particularly in hot climate situations. "[They] should be considered to provide an exogenous carbohydrate source to sustain carbohydrate oxidation and endurance performance," the study noted. For less intensive workouts, however, the study concluded that "water alone is sufficient for fluid replacement."
