High Performance Carbs is the ideal stimulant-free complex carbohydrate energy source for boosting your performance in the gym, for competitive events, for endurance activities, or use it as a component of a muscle-building program. What it is: The only ingredient in High Performance Carbs is a special form of maltodextrin (from corn) containing medium-length glucose polymers. These complex carbs are more readily absorbed by the body and easier to digest compared to many carbs found in many foods. This makes it perfect for before, during and after exercise when you don't want to feel weighed down. How it works: These complex carbs give you a competitive edge since they promote glycogen synthesis, the process that replenishes glycogen (carbohydrate stores) in the muscle and liver. Glycogen is the body's most important fuel during intense exercise. The more glycogen available to your muscles, the longer and harder you can compete or train before fatigue sets in. Depleted glycogen levels lead to exhaustion, poor performance and impaired recovery for your next event. Use High Performance Carbs to easily and efficiently replenish depleted glycogen stores, fuel hardworking muscles and restore energy levels.
