If you sweat, you need BOA Endure.

As athletes fully exert themselves in training and competitions, they lose sodium. Endure is designed to close this sodium gap rapidly.

Tested & Certified

NSF Certified for Sport® certification is the only independent third-party certification program recognized by the United States Anti-Doping Agency (USADA), Major League Baseball, the National Hockey League and the Canadian Football League. Certified for Sport® is also recommended by the NFL, NBA, PGA, LPGA, CCES, CPSDA, iNADO, Ironman, NASCAR, Taylor Hooton Foundation and many other organizations to mitigate the risks of contaminated dietary supplements.

Convenient

Designed to be quickly deployed during training or competition, all you need to do is grab a can of BOA and take a two-second blast. No more biting, tearing or dipping.

Concentrated

ENDURE delivers 150mg of sodium per serving. Our smallest can delivers 25 servings. You would need to drink more than 23, 12oz bottles of the leading isotonic beverage to get the same amount of sodium.

Great-tasting

Our scientist have developed a sodium supplement that tastes great with no aftertaste. No more gutting down harsh substances to fill the sodium gap.

Fast-Acting

BOA's products use our proprietary OraBlast technology to rapidly deliver nutrients that aid in the delay of the onset of fatigue.* Hydrate up to 10 times faster with ENDURE.

The Comparison.

One serving of BOA ENDURE contains 150 mg of sodium. That's roughly the same amount in a 12oz bottle of your favorite isotonic beverage. Our smallest 2oz can has 3,750mg of sodium, the equivalent of 24 bottles. You do the math.

"BOA's ENDURE is a real game-changer. In my view, every athlete - from Olympian to Ironman to amateur sports - should be using it."

— Olympian Ryan Bolton

"BOA fills a huge void in the Sports Nutrition world."

— Susan Kitchen, Registered dietitian, board certified sports nutritionist, a USA Triathlon Level II and IRONMAN certified endurance coach, and a lifelong endurance athlete.

Athletes need sodium.

If you're an athlete, you need more sodium because it's lost while exerting and sweating. If you lose too much sodium too rapidly, your performance will suffer because sodium is a critical ingredient in hydration.

The sodium gap is real.

When you drink your favorite isotonic beverage, you'll feel the effects of the nutrients in about 30-60 minutes on average. And because the amount of sodium is limited by the amount of fluids, you can fall behind and not be able to keep up with the sodium gap. BOA ENDURE is rapidly absorbed by the body, allowing the fluids consumed from your hydration strategy to get pulled into your cells and muscles much faster.

I've never seen anything like it

I’ve seen every kind of supplement under the sun, but I have never seen anything like BOA. I bike with BOA, I run with BOA, and I always have it near me.

So easy to use

"BOA is so easy to use, I just took blasts throughout the race (World's Toughest Mudder) and didn’t even have to break stride. I’m not participating in any endurance events without BOA."
