Niacin

Niacin, noma i-Vitamin B3, ingenye yamavithamini abalulekile we-B-tata ancibilikayo amanzi ukuthi umzimba udinga ukuguqula ukudla kube amandla. Wonke amavithamini namaminerali abalulekile empilweni efanelekile, kepha uNiacin muhle kakhulu ngezinhlelo zokugaya nokugaya. Ake sithathe ukujula okujulile kokuqonda kangcono izinzuzo ze-niacin nemiphumela emibi.

Ngokwemvelo uNiacin ukhona ekudleni okuningi futhi uyatholakala ngesengezo kanye nefomu elinikezwayo, ngakho-ke kulula ukuthola i-niacin eyanele futhi uthole izinzuzo zayo zezempilo. Izicubu emzimbeni ziguqula i-niacin ibe yi-coenzyme esetshenziswayo ebizwa ngeNicotinamide Adenine DinUCleotide (i-NAD), esetshenziswa ngama-enzyme angaphezu kwama-400 emzimbeni ukwenza imisebenzi ebalulekile.

Yize ukushiyeka kwe-niacin kungavamile phakathi kwabantu e-United States, kungaba nzima futhi kubangele isifo sohlelo olubizwa ngePellagra. Amacala amancane wePellagra angadala isifo sohudo kanye ne-dermatitis, kuyilapho amacala abi kakhulu angadala ukuwohloka komqondo futhi abulale.

I-PELLAGRA ivame kakhulu kubantu abadala phakathi kweminyaka engama-20 kuye kwangama-50 ubudala, kepha ingavikeleka ngokuthola imvume yokudla okunconyiwe (i-RDA) yeNiacin. I-RDA endala ye-NIACIN ingu-14 kuye ku-16 mg ngosuku. I-Niacin itholakala kalula ekudleni okufana nenhlanzi, inkukhu, inyama yenkomo, turkey, izithelo nemifino. I-niacin nayo ingenziwa emzimbeni kusuka ku-ad tryptophan ye-amino acid. Le acid ye-amino itholakala ekudleni okufana nenkukhu, turkey, amantongomane, imbewu, nemikhiqizo ye-soy.

I-niacin nayo isemidlalweni eminingi ekhawulayo njengezengezo zokudla. Zombili imvelo ezenziwe kanye nama-multivitamins amadala aseCentrum aqukethe ama-20 mg we-NIACIN ngethebhulethi ngayinye, okungama-125% e-RDA yabantu abadala. I-nicotin acid ne-nicotinamide yizindlela ezimbili ze-niacin izithasiselo. Izithasiselo eziphikisayo ze-NIACIN zitholakala ngamandla ahlukahlukene (50 mg, 100 mg, 250 mg, 500 mg) aphakeme kune-RDA. Izinhlobo ezinikezwayo ze-NIACIN zifaka amagama akwaBrand anjengeNiaspan (Extended-Reled) kanye ne-niacor (ukukhishwa ngokushesha) futhi zitholakala ngamandla aphezulu njenge-1 000 mg. I-niacin ingatholakala ekwakhekeni okudedelwe okunwetshiwe ukunciphisa imiphumela emibi.

Kwesinye isikhathi uNiacin unqunywe eceleni kwemithi ye-cholesterol ehlisa ama-statins ukusiza amazinga e-lipid yegazi.

Obunye ubufakazi bukhombisa ukuthi i-niacin ilungele abantu abanengozi eyandayo yokuhlaselwa yinhliziyo kanye nesifo senhliziyo ngoba akugcini nje ngokutholwa kwe-cholesterol kodwa nama-triglycerides. UNiacin anganciphisa amazinga we-triglyceride ngo-20% kuya ku-50%.
