1,4-Dihydronicotinamide Riboside (NRH)wani nau'in bitamin B3 ne mai saurin canzawa, wanda aka tabbatar da shi a kimiyance don haɓaka matakan NAD+ na tantanin halitta tare da saurin aiki da inganci mara misaltuwa. A matsayinsa na mai samar da NAD+ kai tsaye, wanda ke samuwa a cikin ƙwayoyin halitta, NRH ya fi ƙarfin abubuwan ƙarfafa NAD+ na gargajiya kamar Nicotinamide Riboside (NR) da Nicotinamide Mononucleotide (NMN), wanda hakan ya sa ya zama zaɓi mafi kyau don hana tsufa, lafiyar metabolism, da juriya ga ƙwayoyin halitta. Tare da goyon bayan bincike da aka yi wa takwarorinsu da hanyoyin haɗa sinadarai masu sassauƙa, NRH tana shirye ta mamaye kasuwannin abinci mai gina jiki, cosmeceutical, da magunguna.

1. Ingancin NAD+ na Haɗawa mara misaltuwa
- Sau 2.5-10 cikin sauri na NAD+ idan aka kwatanta da NR ko NMN, wanda ke kaiwa ga kololuwar NAD+ ta salula cikin awa 1.
- Hanyar juyawa kai tsaye: Yana ketare matsalolin metabolism ta hanyar amfani da adenosine kinase da enzymes na NMNAT, sabanin NR, wanda ke buƙatar phosphorylation.
- Ingantaccen aikin redox: Rage girman siffa (NRH) yana ba da gudummawar electrons kai tsaye don sake farfado da wuraren NAD+, yana tallafawa samar da makamashi na mitochondrial da gyaran DNA.
2. Ingantaccen Kwanciyar Hankali da Tsarkaka
- An samu kashi 96% na tsarki ta hanyar ingantaccen tsarin anaerobic da kuma chromatography na shafi.
- Yana da kwanciyar hankali a ƙarƙashin yanayin alkaline (pH 8.1–9.0): Ya dace da ƙarin sinadaran da ke buƙatar tsawon lokacin shiryawa.
- Mai jure wa lalacewa: Mafi ƙarancin hydrolysis/oxyidation idan aka adana a cikin kwantena masu hana iska shiga, masu jure haske a 4°C.
3. Fa'idodi da aka Tabbatar a Asibiti
- Hana Tsufa: Yana kunna sirtuins (SIRT1/3) da PARPs don haɓaka gyaran DNA, rage damuwa ta oxidative, da kuma jinkirta raguwar tsufa.
- Lafiyar Jiki: Yana inganta yanayin insulin, aikin mitochondrial, da kuma samar da ATP.
- Kariyar Jijiyoyi: Yana tallafawa aikin fahimta ta hanyar kiyaye matakan NAD+ a cikin kyallen kwakwalwa.
- Kariyar Gabobi: Yana rage gubar koda da cisplatin ke haifarwa kuma yana rage lalacewar ƙwayoyin halitta daga genotoxins kamar hydrogen peroxide.

NRH tana aiki ta hanyar wata hanya ta musamman ta enzyme daban da NR:
- Canjin NAD+ kai tsaye: NRH yana ketare matakin phosphorylation na NRK1/2, wanda ke ba da damar haɗa NAD+ cikin sauri ta hanyar adenosine kinase da NMNAT.
- Ma'aunin Redox: A matsayin raguwar NAD+, NRH tana ba da gudummawar electrons don sake farfado da wuraren waha na NAD+, wanda yake da mahimmanci ga jigilar lantarki na mitochondrial da kariyar antioxidant.
- Haɗin gwiwa da Sirtuins: Ƙara NAD+ yana kunna SIRT1/3, yana haɓaka deacetylation na sunadaran metabolism da kuma haɓaka tsawon rai.

1. Sinadaran Abinci Mai Gina Jiki
- Karin Maganin Tsufa: 50-250 MG/rana don sake cika NAD+ da gyaran ƙwayoyin halitta.
- Masu Inganta Makamashi: Suna haɓaka samar da ATP kuma suna rage gajiya da motsa jiki ke haifarwa.
2. Kayan shafawa
- Tsarin shafawa na fata (0.5–2%): Yana haɓaka haɗakar collagen, yana rage lalacewar iskar shaka da UV ke haifarwa, kuma yana inganta laushin fata.
3. Magunguna
- Binciken Cututtukan da ke Rage Jijiyoyin Jijiyoyi: An yi bincike kan cutar Alzheimer da Parkinson saboda tasirin kariya daga jijiyoyi.
- Kariyar Chemo: Yana rage gubar gabobi da ke haifar da chemotherapy (misali, gubar nephrotoxicity na cisplatin).
