Kunezinhlobo ezingaphezu kweshumi nambili zamavithamini B, futhi eziyisishiyagalolunye zazo zibonwa emhlabeni wonke njengamavithamini abalulekile emzimbeni womuntu. Wonke angamavithamini ancibilikayo emanzini ahlala kuphela emzimbeni amahora ambalwa futhi kufanele engezwe nsuku zonke. Iqembu B liyisakhi esibalulekile kuzo zonke izicubu zomuntu futhi liyisihluthulelo sokukhulula amandla ekudleni. Wonke ama-coenzymes ahilelekile ekugayweni koshukela, amaprotheni, namafutha emzimbeni, ngakho-ke ahlukaniswa njengomndeni.

Wonke uvithamini B kumele enze kanyekanye, owaziwa ngokuthi umphumela wokuhlanganisa uvithamini B. Ukusebenzisa i-VB ethile kukodwa kwandisa isidingo samanye ama-VB ngenxa yokwanda komsebenzi wamaselula, ngakho-ke imisebenzi yama-VB ahlukahlukene iyahambisana, eyaziwa ngokuthi "isimiso somphongolo". URoger Dr. William waveza ukuthi wonke amaseli anesidingo esifanayo ncamashi se-VB.

Amavithamini B ahlobene eduze nokunakekelwa kwesikhumba ahlanganisa i-B1, B2, B3, B5, B6, ne-H. I-Vitamin B1, eyaziwa nangokuthi i-thiamine, ingavimbela umsebenzi we-cholinesterase, inciphise ukuvuvukala kwesikhumba, futhi inomphumela wokuvimbela nokwelapha i-seborrheic dermatitis, i-eczema, nokukhuthaza impilo yesikhumba. Itholakala kakhulu okusanhlamvu, imifino emisha, izithelo, ubisi, izikhupha zamaqanda, inyama engenawo amandla, isibindi, imvubelo, bran, amantongomane, njll. I-Vitamin B2, eyaziwa nangokuthi i-riboflavin, ibamba iqhaza ekuphenduleni kwe-redox yeselula, ukuhlanganiswa kwe-hemoglobin, kanye ne-metabolism kashukela, amaprotheni, namafutha. Kungasiza isikhumba ukumelana nokulimala okuvela ekukhanyeni kwelanga futhi kukhuthaze ukuvuselelwa kwamaseli. Uma kukhona ukuntuleka kwevithamini B2 emzimbeni, isikhumba sizwela kakhulu ekukhanyeni kwelanga futhi sivame ukubhekana ne-solar dermatitis. Ngemva kokuchayeka elangeni isikhathi eside, ubuso buba bomvu futhi bulume, bese kuvela izinto eziyimpushana emakhaleni. Ikakhulukazi itholakala ezikhiqizweni zamaqanda, ubisi, imvubelo, imifino enamahlamvu aluhlaza, i-rice bran, igciwane, isibindi sesilwane nezinso, izaqathe, imvubelo yotshwala, inhlanzi, amawolintshi, ama-tangerine, amawolintshi, njll. I-Vitamin B3, eyaziwa nangokuthi i-niacin, ingavimbela ukwakheka kwe-melanin esikhumbeni futhi ivimbele ukuhwalala kwesikhumba. Kuwusizo ekubuyiseleni amaseli awonakele noma isikhumba. Idlala indima ebalulekile ekugcineni ubuqotho bezicubu ezivamile, ikakhulukazi isikhumba, umgudu wokugaya ukudla, kanye nesimiso sezinzwa. I-Vitamin B6 ihlobene eduze nempilo yesikhumba futhi iyingxenye yesakhiwo samangqamuzana ama-enzyme amaningi nama-enzyme asizayo. Ukuthuthukisa i-metabolism yama-amino acids ukuze kugcinwe impilo yesikhumba kunganciphisa ukuqina kodonga lwe-capillary kanye nomsebenzi we-hyaluronidase, kunciphise ukungezwani komzimba nokuvuvukala, futhi kukhuthaze ukukhula kwamaseli e-epithelial. Ingasetshenziselwa ukuvimbela nokwelapha isikhumba esimahhadlahhadla, izinduna, ukushiswa yilanga, ukulunywa, kanye nokushiswa yilanga. Ingase futhi isetshenziselwe ukuvimbela nokwelapha ukuvuvukala kwesikhumba se-seborrheic, izinduna ezivamile, i-seborrheic dermatitis eyomile, i-eczema, nezinguquko zesikhumba ezivulekile. Ikakhulukazi itholakala esibindini, isikhupha seqanda, okusanhlamvu, amagciwane, ubhontshisi, ubisi, inhlanzi, inyama nemifino. I-Vitamin H, eyaziwa nangokuthi i-biotin, ingakhuthaza umzimba wesikhumba, ithuthukise ukuhwalala kwesikhumba, ivimbele ukulahlekelwa izinwele, i-seborrheic dermatitis, kanye ne-polymorphic acne. Itholakala ekudleni okufana nesibindi, isikhuphasha seqanda, ubisi, imvubelo, njll.

Amalungu avamile omndeni kavithamini B yi-B1.B2.B3 (niacin), B5 (pantothenic acid), B6.B9 (folate), kanye ne-B12 (cobalamin).
