Sportspeople who undergo regular strenuous training walk a tightrope betwwen optimum physical health and an impaired immune function. Resarch results suggest that athletes have a higher risk for infections of the upper respiratory tract during periods of hard training or for 7- 14 days after a hard competition (Nieman, 1990). Viewed in the long term, physical activity strengthens the immune system, although physical activity causes the formation of free radicals in the sort term. These free radicals are very damaging to the cells and they can weaken the immune defenses. Anti-oxidants can intercept these free radicals, so they are cell-protecting substances. Five portions of fruit and begetables per day will usually provide an adequate supply of anti-oxidants (according of training and competition can take advantage of ACE supplements. In this case, Sponser recommends Protector Tabs.

NucleoCell is a dietary supplement based on natural RNA and nucleotides, the building blocks of cell synthesis. All the rapidly dividing cells of the body (e.g. cells of immunity, blood cells, and mucosa cells in the digestive tract) are able to use these building blocks and thereby optimise their fundamental body functions, like defense forces, blood cell formation, protein synthesis, nutrient absorption, and liver functions. Several scientific human studies have confirmed the strenghtening effect of NucleoCell on the body's defensive forces, reduced lactate and Ldl-cholesterol values.
