Unless you supplement your carbohydrate source with protein, your body will start to digest its own protein (muscle tissue) for energy after about 90 minutes of hard exercise. So when your training takes you beyond the range of Hammer Gel alone, you can rely on Hammer Nutrition Sustained Energy with its 7:1 carbohydrate/protein ratio.

Sustained Energy contains a superior blend of complex carbohydrates, a precise amount of protein, and a few carefully selected micronutrients that all work synergistically to provide consistent, long-lasting energy. With Sustained Energy, you'll have 100% confidence in your fuel, even during your longest and hardest training sessions and races. Without any added flavoring or sweeteners, it has a pleasant neutral flavor with no sickly-sugary energy drink taste. Since 1992, Sustained Energy has stood the test of time in every conceivable endurance and ultra-endurance event. No matter how difficult or lengthy your exercise or race is, Sustained Energy will come through every time, and keep you going mile after mile, hour after hour.

Hammer Nutrition Sustained Energy is easy to digest, with no stomach distress common with other sugar-filled sports drinks. It provides steady, predictable energy from a precise ratio of carbohydrate to protein. It enhances fat utilization from accessory nutrients and provides you with increased lactic acid buffering. It comes in convenient, versatile powder, and one container has 30 servings. It's ideal for workouts and races that last more than three hours.

Here's what others have to say...

Does this contain any milk/whey products?...

Does this contain any milk/whey products? I'm lactose intolerant and have been having difficulties finding a sports drink that I can use. I need one that can provide carbs, protein, and electrolytes. Suggestions? I'll be using it for long distance hiking in hot temps, as well as running, cycling, and swimming.

Responded on

It does not contain any dairy products or whey, however it is processed in a facility that also processes dairy ingredients.

Sustained Endurance Rides & Long Summits

  • Familiarity: I've put it through the wringer

I've been using the Sustained Energy since the early days (1995) of Hammer Nutrition (eCaps). It was a shocker at first for my system because of the unflavored taste which was a change from all the other energy sources who juice up the bad tasting products with unnatural flavoring which can lead to gastrointestinal problems. I found this to be a great product for long endurance rides and I used it for a UMCA Michigan state record along with many other endurance events with awesome results. I also found that adding some of the Hammer Gel would give me a flavor and keeping my taste-buds and body happier.

Not a cyclist?

Well this also has been part of my mountaineering nutrition and it'll add more energy for those long summit attempts where gels alone won't cut it.
