Óleo de Gérmen de Trigo

O Óleo de Gérmen de Trigo é extraído do grão do trigo, a parte mais nutritiva desta planta por conter todos os nutrientes necessários para a sua reprodução. É uma fonte natural de ácidos gordos insaturados e de fitonutrientes, que incluem os tocoferóis, os fitosteróis, os carotenóides e os compostos fenólicos⁽¹⁾. Este óleo é rico em triglicéridos nomeadamente os ácidos linoléico, palmítico, oléico e esteárico, e em ómegas 3 e 6. Apresenta também um elevado teor de proteína e respetivos aminoácidos (albumina e globulina) e de minerais como o potássio, o magnésio, o cálcio, o zinco e o manganésio⁽²⁾. A sua composição bastante nutritiva aparenta ter efeitos benéficos ao organismo^{(3,4,5,6,7,8,9)}.
