Natural Help for Combating Fatigue after Exercise

Klean Endurance by Klean Athlete may help athletes restore energy, support cardiac function, and reduce muscle stiffness, soreness, and fatigue.

This great-tasting chew supports the natural way your body produces energy with all-natural d-ribose.

D-ribose is a sugar your body uses to produce ATP, or adenosine triphosphate, the source of chemical energy in your skeletal muscles that enables them to contract and relax.

When your muscles have sufficient ATP levels, you should be less susceptible to muscle fatigue, tightness, and cramping.

D-ribose may also help reduce the loss of energy during stress and accelerate energy and tissue recovery.

Energy depletion may negatively affect muscle performance or how you feel after exercise.

The loss of energy in muscles contributes to the common symptoms of stiffness, soreness, weakness, and pain after exercise. Protein synthesis, of vital importance to athletes, can also be affected.

NSF Certified Formula

Klean Endurance has been approved by the NSF Certified for Sport program, which was established to meet the growing demands of athletes, coaches, and healthcare professionals to guarantee that sports supplements are free from banned substances.


For best results, take 1-3 chewable tablets within 15-30 minutes before and just after exercise or physical activity. This formula is best taken with a food or sugar source to avoid low blood sugar.

Klean Endurance chewable tablets are sweetened naturally and contain natural orange/vanilla flavoring.
