Anxiety reduction observed with lysine
We investigated how L-lysine, an essential amino acid, influences anxiety and body weight. The study involved administering two doses of L-lys to rats over 20 days.
We found that while L-lys didn't affect food intake, it did lead to weight reduction and showed signs of anxiolytic effects on the first day. Notably, repeated doses increased serotonin levels in key brain areas, which may explain its calming effects.
However, the study's outcomes indicate that L-lys may not dramatically alter anxiety compared to other treatments.

Amino acid aids anxiety
I recommend this hazelnut-derived amino acid. It strengthens immunity, enhances skin and hair, stimulates muscle growth, and reduces anxiety. I noticed results after a few weeks, and there have been no side effects on my stomach.
