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.*
- 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.*
- Klean is Clean. Klean Athlete products are GMO-free and formulated without wheat, gluten, or artificial coloring, flavoring or sweeteners. Every product is third party certified by NSF International's NSF Certified for Sport program, to help athletes, coaches and trainers make more informed decisions when choosing sports supplements.
- Fuel Your Foundation. Perform At Your Peak. We power health and peak performance in athletes who demand the most from themselves, their sport and their nutrition.*
