N2 - Yeast based spreads (YBS) such as marmite and vegemite, made from leftover brewer's yeast extract are one of the world's richest source of B vitamins. We evaluated symptoms of depression, anxiety, stress scores (DASS) in participants who consume or do not consume YBS. 520 participants completed a survey consisting of 70–94 questions relating to the consumption of YBS, dietary and lifestyle habits and mood symptoms of DASS. Parametric analysis co-varying for gender, diet, supplement use, soy milk and alcohol consumption and history of psychiatric disorders including depression and anxiety were utilized to analyse the results. A significant improvement was noted in anxiety and stress but not depressive symptoms in those consuming YBS. Furthermore, those who consumed vitamin B12 fortified YBS showed even greater improvement in stress symptomology. Vitamin B supplementation appears to be an important additive supplementary source to improved stress and anxiety in the general adult population.
