Pantetin (bis-pantetin, koenzimski pantetin) je dimerna forma pantotenske kiseline (vitamina B₅). On se sastoji od dva molekula pantotenske kiseline vezana cistaminskim grupama. Monomer ovog jedinjenja je poznat kao pantetein i on je intermedijer u produkciji koenzima u telu. Pantetin se smatra biološki aktivnijom formom vitamina B₅, ali je manje stabilan, i razlaže se tokom vremena, ako se ne čuva u frižideru.

Dijetarna suplementacija uredi

Pantetin je dostupan kao dijetarni suplement jer postoje dokazi da je koristan za zdravlje. U više kliničkih ispitivanja na pacijentima sa povišenim nivoima holesterola i triglicerida, totalni i LDL holesterol su umanjeni za 12%, trigliceridi za 18%, i HDL holesterol je povišen za 9%.^[4]^[5] Ova klinička ispitivanja su sprovedena koristeći dnevne doze u opsegu od 600 do 1200 mg/dan. U tom opsegu doza nema evidencije o postojanju odnosa doze i efekta.^[6]

Dalja ispitivanja sa dozama u opsegu 600 – 900 mg/dan su pokazala statistički značajno sniženje nivoa LDL holesterola kod osoba sa znatno ili umereno povišenim nivoima lipida u krvi.^[7]
