Endurance athletes are special and require special hydration. Invigorade Endurance Drink is formulated with a proprietary tri-carbohydrate blend that translates into readily available energy, thus improving performance. Plus it has β-alanine, an amino acid that scientific studies show increases muscular strength, power output, and endurance and delays muscular fatigue. From a taste standpoint, these drinks hit the mark – refreshing, not too sweet or overpowering, and they come in 3 great flavors (tropical punch,orange mango, and coconut). Invigorade is ideal for active TrailblazerGirls.
