Vitamin B3, tako\u0111er poznat kao niacin ili nikotinska kiselina, esencijalni je nutrijent koji se nalazi u hrani i va\u017ean je za pravilno funkcionisanje tijela. On spada u skupinu B vitamina, koji su odgovorni za odr\u017eavanje zdravlja ko\u017ee, probave i \u017eiv\u010danog sustava, te sudjeluju u procesu pretvaranja hrane u energiju.<\/p>\n\n\n\n

Vitamin B3 ima nekoliko klju\u010dnih funkcija u tijelu. On je va\u017ean za metabolizam ugljikohidrata, masti i proteina, te poma\u017ee u pretvaranju hrane u energiju koju tijelo mo\u017ee koristiti. Tako\u0111er sudjeluje u sintezi raznih hormona i neurotransmitera u tijelu, uklju\u010duju\u0107i stvaranje serotonina<\/strong><\/a>, koji je povezan s raspolo\u017eenjem.<\/p>\n\n\n\n

Niacin ima pozitivan u\u010dinak na zdravlje ko\u017ee. Mo\u017ee pomo\u0107i u smanjenju simptoma akni i drugih ko\u017enih bolesti te pobolj\u0161ati cjelokupno stanje ko\u017ee lica. Tako\u0111er je va\u017ean za odr\u017eavanje zdravlja i podr\u017eavanje normalne funkcije mozga.<\/p>\n\n\n\n

Vitamin B3<\/h2>\n\n\n\n

Nakon najnovijih istra\u017eivanja stru\u010dnjaci su zaklju\u010dili da velike doze vitamina B3 podsti\u010du odbrambeni mehanizam organizma da stvara antitijela koja su sposobna da uni\u0161tavaju bakterije otporne na antibiotike, tzv. super-bakterije.<\/p>\n\n\n\n

Naime, uslijed mutacije odre\u0111enih gena, bakterije sve \u010de\u0161\u0107e postaju otporne na sve poznate antibiotike, pa \u010dak i one posebno pravljenje za njihovo uni\u0161tavanje. Istra\u017eivanja su pokazala da neke opasne infekcije nastaju kao posljedica nedostatka odre\u0111enih proteina u neutrofilima, ali da visoke doze vitamina B3 poja\u010davaju lu\u010denje ovog proteina u \u0107elijama imunolo\u0161kog sistema.<\/p>\n\n\n\n

Istra\u017eivanje je najprije provedeno na mi\u0161evima, ali je kasnije i na ljudskim \u0107elijama dalo identi\u010dne rezultate. <\/p>\n\n\n\n

Manjak vitamina B3 mo\u017ee se iskazivati brojnim simptomima od gubitka mi\u0161i\u0107ne mase, mr\u0161avljenja, glavobolje, povra\u0107anja, lo\u0161e probave i nepravilne funkcije crijeva do lo\u0161eg zadaha i ko\u017enih problema, poput dermatitisa. Problemi na desnima i jeziku, pra\u0107eni mu\u010dninom i razdra\u017eljivo\u0161\u0107u, tako\u0111er se mogu povezati s manjkom tog vitamina. <\/p>\n\n\n\n

S druge strane, u prevelikim dozama vitamin B3 mo\u017ee biti toksi\u010dan. U tom slu\u010daju glavni simptomi su pro\u0161irenje krvnih \u017eila pra\u0107eno padom krvnog tlaka i valovima vru\u0107ine, eritemom, svrbe\u017eom, bolom u podru\u010dju jetre, mu\u010dninom, glavoboljom, proljevom.<\/p>\n\n\n\n

Preporu\u010deni dnevni unos<\/strong> vitamina B3 za odrasle osobe je 14 mg za \u017eene (od 11. godine), te 18 mg za mu\u0161karce (od 14. godine). Trudnicama se preporu\u010duje uzeti blago povi\u0161enu dozu, ali isklju\u010divo u dogovoru sa ljekarom, ne na svoju ruku.<\/p>\n\n\n

Namirnice bogate b3 vitaminom<\/strong> su meso, riba, ora\u0161asti plodovi<\/strong><\/a>, sjemenke, mlijeko, jaja, integralne \u017eitarice i povr\u0107e. Tako\u0111er se mo\u017ee uzimati kao dodatak prehrani u obliku vitamina B3 ili nikotinske kiseline.<\/p>\n","protected":false},"excerpt":{"rendered":"
