L-Tyrosine for Social Anxiety
RESEARCH
- Works for stress response in some situations, but benefits are inconsistent and may depend on whether dopamine is already depleted.
COMMUNITY
- Some users report initial relief from depression and anxiety, but effects fade quickly and daily use can cause mood crashes.
SAFETYDaily supplementation may worsen mood by creating dopamine/serotonin imbalances; use intermittently and monitor for depressive symptoms.

“i loved l-tyrosine. but don't take it daily; it made me depressive after taking it daily, because of the dopamine/serotonin imbalance...”
U/SUBSTANTIALBUG1746 ↗“i feel people get a very strong placebo effect from certain substances because many studies on tyrosine suggest it does nothing and the ones that show an effect are under scenarios of DA/NE depletion and even then the effect size doesnt seem very big however it is still possible theres just not enough research on it. none of the human studies ive seen are particularly high quality”
U/OPTIMALCONCEPT1975 ↗“I had been super isolated and in a deep hole mentally. I read tons about depression, anxiety, anhedonia and insomnia. Decided to give l-tyrosine a go as my first supplement to try. I must have been so depleted because I went on to have no resistance to tasks, could actually plan the next task and so many other benefits. Then, nothing on day 3-4(?). It gave me enough of a glimpse into the minds of "healthy" people that I began my human N=1 trials. I was in utter stagnation that was beyond anything I could try to label it as. I barely recognize that past self at all.”
