Athletes often tend to cross the line between sporting effort and total exhaustion – and thus also the line between health promotion and overstraining the body. Several studies have shown that excessive sporting activity such as marathon competition or training, mountain cross, triathlon, cross-fit or even intensive training in untrained individuals weakens the immune system and increases susceptibility to infections1-6). It has been found that there is a significant correlation between training load and occurrence of colds. In addition, the weakening of the body through cold symptoms impairs the further training of athletes.
If you are preparing your immune system for an athletic challenge or generally do a lot of sports, it is advisable to train your immune system as well. ApuXan® with its very well absorbable beta-glucans and zinc can help you to do so.*
*Zinc contributes to a normal function of the immune system.
