Brak w magazynie

Witamina B3, C₆H₅NO₂, znana również jako Niacyna, jest jedną z ośmiu spośród kompleksu witamin B. Jest niezbędna dla dobrego samopoczucia organizmu człowieka, ponieważ bierze udział w przekształcaniu pożywienia w energię. Ponadto witamina B3 pomaga w utrzymaniu zdrowego układu nerwowego i jest niezbędnym składnikiem produktów do pielęgnacji skóry.

Witamina B3 jest wytwarzana przez organizm ludzki, jednak ze względu na swoją rozpuszczalność w wodzie nie może być magazynowana i konieczne jest zapewnienie jej odpowiedniej podaży.

Witamina B3 (niacyna) może występować w dwóch postaciach – kwaśnej (jako kwas nikotynowy) i aktywnej (jako amid nikotynowy). Pierwsza forma jest bardziej stabilna i taka też jest w naszej ofercie.
