what amino acid is used to create dopamine, which supports happiness and reduces aggression?

The amino acid used to create dopamine is tyrosine.

Quick Scoop Answer

Dopamine in the brain is synthesized from the amino acid tyrosine, which is first converted to L-DOPA and then to dopamine. Tyrosine itself can come directly from your diet or be made in the body from another amino acid, phenylalanine. Because dopamine is involved in motivation, reward, and mood regulation, adequate tyrosine intake is often linked to supporting feelings of well‑being and helping regulate stress and aggressive behavior, although many other biological and psychological factors also play a role.
