Supplements Are For More Than Just Before And After Training

Most athletes go to great lengths to plan their pre- and post-training nutrition and supplementation, especially when they’re dieting. It’s not just before and after workouts when you need to think of fueling your muscles. Those who are looking to be number one are always searching for an extra edge, and one of the few times that many athletes forget to keep themselves fueled is during their workouts…

In-Workout Nutrition Is The Key To Top Performance

If you want to be at the absolute top of your game, it’s imperative to think about keeping yourself fueled and preventing muscle breakdown during your hard training sessions. This is why SAN created an essential intra-workout formula.*

INTRA FUEL™ is designed to be the ultimate fuel source during workouts. With its perfect balance of key EAAs and BCAAs, the SAN EAA Complex™ helps prevent catabolism, or the breakdown of muscle tissue, during and after your workouts. The SAN Endurance Complex™ features nitric oxide boosting elements and CarnoSyn beta-alanine for its ability to synthesize carnosine in muscle cells. This buffers muscle burn and allows you to keep pushing your hardest through your training.*

Even mild dehydration can have a negative effect on strength, endurance and focus. INTRA FUEL™ safeguards you from this by keeping you properly hydrated with critical electrolytes, plus a vital blend of vitamins and minerals to keep you fully nourished all the way through your most grueling workouts.*

When you need to prevent muscle breakdown and fuel endurance and recovery during intense workouts, INTRA FUEL™ is your high-octane choice.*
