La Vitamina K svolge una funzione fondamentale nella coagulazione del sangue. La sua mancanza provocherebbe una non rimarginazione delle ferite.

Altro ruolo importante è la regolazione del funzionamento dei reni.

Questo studio presenta le ultime evidenze scientifiche sulla vitamina K e sul suo ruolo nella prevenzione delle malattie associate all'età e /o nel miglioramento dell'efficacia dei trattamenti medici negli adulti maturi ˃50 anni (1).

Si trova in :

• Verdure, cavoli, spinaci
• Frutta, banane
• Tè verde
