Clif Quench The Natural Performance EnhancerCLIF SHOT is all about delivering great-tasting, scientifically-backed, and sustainably-produced products to performance athletes. In other words, energy food can taste great and be made from good-for-the-planet ingredients. It's that simple. Hydration - An endurance athlete's #1 concern should be hydration. Performance declines with as little as 2-3% dehydration, not to mention the more serious overall health risks beyond that level. CLIF SHOT(R) Electrolyte is designed to deliver fluids to your body at an optimal rate as you sweat them out. Electrolyte contains high levels of sodium and tartness, so that it will quench your thirst, and then subtly prime your thirst mechanism. That way, you keep drinking and stay hydrated. After hard training or racing, you could be moderately dehydrated.
