With 90 chewable tablets in a delicious vanilla crème flavor, this NSF Certified product ensures athletes can recover quickly and safely after intense workouts. ## Description Klean Endurance contains pure D-Ribose to support the natural process by which a body produces adenosine triphosphate (ATP). The naturally-occurring pentose sugar supports cardiovascular health, energy production and mitochondrial function. Available in a great-tasting chewable tablet, Klean Endurance offers a clinically proven method to help restore energy during exercise. ## Features - RECOVERY: Consuming after a workout helps speed muscle recovery, restore energy, support cardiac function and reduce muscle stiffness, soreness, and fatigue.* - ENERGY: D-Ribose is the critical building block for producing ATP, the energy currency of the cell. Supplementing with D-Ribose allows the muscles to bypass the slow, rate-limited process of making ribose from glucose, thereby accelerating energy synthesis and recovery.* - FAST ACTING & TASTES GREAT: Endurance chews are great-tasting, convenient to take, and work within 15 minutes of consumption.* - DOES NOT CONTAIN: This product contains NO salt, yeast, wheat, gluten, soy, artificial coloring, artificial preservatives or genetically modified organisms (GMOs). - NSF CERTIFIED: Klean Athlete is a line of NSF Certified for Sport nutritional supplements certified free from banned substances and contaminants. Our suite of targeted products promotes peak performance by fueling and fortifying with a solid nutritional base to support an athlete’s training and overall well-being.* *These statements have not been evaluated by the Food and Drug Administration.
