Nuun’s brightly colored packaging and easy-to-use electrolyte tablets have become a staple for many endurance athletes. Now the Seattle-based company is introducing Performance, a powdered drink mix. Performance is designed for efforts lasting more than 90 minutes and includes both electrolytes and carbohydrates (equal parts dextrose and sucrose). The product has been more than two years in the making and uses natural fruit powder, derived from flash-frozen fruit for flavoring. Performance ingredients are non-GMO project certified. Available in two flavors: Mango Orange and Blueberry Strawberry (pictured). Nuun Performance is sold in a 16-serving pouch for $20 and as single serve packets for $2.
