Polypodium leucotomos Extract use to prevent and reduce the risk of infectious diseases in high performance athletes

Infect Drug Resist. 2012;5:149-53. doi: 10.2147/IDR.S29113. Epub 2012 Oct 16.


Objective: Many components of the immune system undergo adverse changes during intense physical activity in athletes, leading to a heightened risk of respiratory tract infections. This study evaluated the reduction in infectious processes in athletes due to intensive training with anapsos.

Methods: The study compared athletes who took 480 mg Polypodium leucotomos Extract (Armaya fuerte; Centrum laboratories, Alicante, Spain) twice daily for 3 months (n = 50) with a control group (n = 50) in the evaluation of the onset of infectious processes and relapses during an 8-month period (June 2010 to January 2011).

Results: The onset of infectious processes in the Polypodium leucotomos Extract group was lower when compared to the control group (14% versus 56%). Relapse in the Polypodium leucotomos Extract group was seen in just one athlete (14.2%) compared to ten athletes (37.5%) in the control group.

Conclusion: Polypodium leucotomos Extract has been shown to be useful in the prevention of infectious processes, as well as reducing recurring episodes in athletes.
