Optimal Nutrition Timing Goes Beyond 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 out when you need to think about fueling your body, though. Those who are looking to be their absolute best are always searching for an extra edge, and one of the few times many athletes forget to keep themselves fueled is during their workouts…

In-Workout Nutrition Is the Key to Peak Performance

If you want to be at the absolute top of your game, it’s crucial to think about keeping yourself fueled during your hard training sessions, as that will keep you going and prevent muscle breakdown .

That’s why SAN created an essential intra-workout formula…

INTRA FUEL is formulated to be the ultimate fuel source during even your most challenging workouts. With its perfect balance of key Essential Amino Acids (EAAs) and Branched-Chain Amino Acids (BCAAs), the SAN EAA Complex™ helps prevent catabolism, or the breakdown of muscle tissue, during and after your workouts. SAN’s Endurance Complex™ features nitric oxide-boosting elements and CarnoSyn beta-alanine for its ability to synthesize carnosine in muscle cells. This buffers lactic acid for less intense muscle burn, allowing you to keep pushing beyond your normal limits throughout your training.

Dehydration, even if only mild, can have a significantly 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.

Prevent muscle breakdown and fuel your endurance and recovery during intense workouts with INTRA FUEL, your high-octane muscle fuel choice.
