Wonky 92 Posted October 16, 2021 Lysine is an essential amino acid, which means that the human body cannot synthesize it. Human studies have also shown negative correlations between lysine intake and anxiety. A population-based study in Syria included 93 families whose diet is primarily grain-based and therefore likely to be deficient in lysine. Fortification of grains with lysine was shown to reduce markers of anxiety, including cortisol levels, and also led to potentiation of benzodiazepine receptors (common targets of anxiolytic drugs such as Xanax and Ativan).
