Vitamina C, cunoscut\u0103 \u0219i ca acid ascorbic<\/strong>, este o vitamin\u0103 solubil\u0103 \u00een ap\u0103, prezent\u0103 \u00een mod natural \u00een multe fructe \u0219i legume. Fiind hidrosolubil\u0103, ea nu se stocheaz\u0103 semnificativ \u00een organism; surplusul se elimin\u0103 prin urin\u0103, de aceea este necesar un aport constant \u00een diet\u0103. Chimic, este un antioxidant puternic ce poate neutraliza radicalii liberi \u0219i are capacitatea de a regenera al\u021bi antioxidan\u021bi din organism (precum vitamina E). Un aspect important este c\u0103 majoritatea animalelor \u00ee\u0219i pot produce propria vitamina C<\/strong>, dar oamenii nu \u2013 din cauza unei muta\u021bii genetice evolutive, depindem exclusiv de sursele alimentare pentru aceast\u0103 vitamin\u0103.<\/p>

Prin urmare, vitamina C este definit\u0103 ca nutrient esen\u021bial<\/strong>.

Unul dintre cele mai cunoscute beneficii ale vitaminei C este efectul pozitiv asupra sistemului imunitar<\/strong>. Vitamina C contribuie la func\u021bionarea normal\u0103 a celulelor imunitare (cum ar fi limfocitele \u0219i fagocitele) \u0219i le protejeaz\u0103 de stresul oxidativ \u00een timpul infec\u021biilor. Altfel spus, ajut\u0103 organismul s\u0103 lupte mai eficient \u00eempotriva microbilor. De exemplu, super-alimente bogate \u00een vitamina C, precum spanacul \u0219i broccoli, pot \u00eent\u0103ri imunitatea<\/strong> \u0219i ajut\u0103 corpul s\u0103 combat\u0103 infec\u021biile.
