Acide Nikotinike ni ikintu gikomeye mu gutanga hydrogen no kurwanya pellagra mu binyabuzima;ifasha kubungabunga ubuzima bwuruhu nubwonko no gutera igogora.
Acide Nikotinike cyangwa niacinamide ikoreshwa mu kuvura no kwirinda pellagra.Iyi ni indwara iterwa no kubura niacin.Niacin ikoreshwa kandi mu kuvura cholesterol nyinshi.Rimwe na rimwe, niacin yafashwe na colestipol irashobora gukora kimwe na colestipol hamwe nubuvuzi bwa statin.
Niacin USP granular ikoreshwa mugukomeza ibiryo, nk'inyongera y'ibiryo ndetse no hagati yimiti.
Urwego rwo kugaburira Niacin rukoreshwa nka vitamine y’inkoko, ingurube, amatungo, amafi, imbwa ninjangwe, nibindi.
Niacin izwi kandi nka vitamine B3.Nibikoresho bikonjesha amazi bigabanya uruhu rukomeye, rwumye, cyangwa runyeganyega, rufasha koroshya uruhu no kunoza ubwiza bwarwo.niacin yongerera isura no kumva umusatsi, mukongera umubiri, ubwiza, cyangwa sheen, cyangwa mugutezimbere imisatsi yangiritse kumubiri cyangwa kuvura imiti.Iyo ikoreshejwe mugutegura ibicuruzwa byita kuruhu, niacinamide na niacin byongera isura yuruhu rwumye cyangwa rwangiritse mugabanya flake no kugarura ubwuzu.
Acide Nikotinike.Nibibanziriza coenzymes NAD na NADP.Ikwirakwizwa cyane muri kamere;umubare ushimishije uboneka mu mwijima, amafi, umusemburo n'ibinyampeke.Kubura indyo bifitanye isano na pellagra.Ijambo "niacin" naryo ryakoreshejwe.
Niacin ni vitamine ikungahaye kuri vitamine ikenewe mu mikurire nubuzima bwimitsi.Irinda pellagra.Ifite ibishishwa bya 1 g muri ml 60 y'amazi kandi byoroshye gushonga mumazi abira.Birasa neza mububiko kandi nta gihombo kibaho muguteka bisanzwe.Inkomoko zirimo umwijima, amashaza, n'amafi.Ubusanzwe yitwaga acide nikotinike kandi ikora nk'intungamubiri n'imirire.

Acide Nicotinic yahawe agaciro kugirango itsipolipidemic yongere.Pentaerythritol tetranicotinate yakoze neza mubigeragezo kuruta niacin mukugabanya urugero rwa cholesterol mu nkwavu.Sorbitol na myo-inositolhexanicotinate polyester yakoreshejwe mu kuvura abarwayi bafite obliterans ya atherosclerose. Igipimo gisanzwe cyo gufata niacin ni 3 kugeza kuri 6 g / daygiven mu byiciro bitatu bigabanijwe.Ubusanzwe imiti itangwa mugihe gito kugirango igabanye igifu gikunze guherekeza dosiye.
