Supplementing the diet with typtophan is well proven to improve mood. One study from Oxford University found that when people were deprived of tryptophan but otherwise had a nutritionally balanced diet, they showed signs of worsening of their mood and depression, and their mood improved when tryptophan was added. This is because tryptophan leads to an increase in the synthesis of serotonin in the brain, and research demonstrates that this chemical improves mood as well as many antidepressant drugs.
Tyrosine is an amino acid that is made from another amino acid- phenylalanine. These amino acids make the neurotransmitter dopamine, responsible for the production of two neurotransmitters associated with depression and lack of motivation- adrenalin and noradrenalin. Studies have found that the amino acids tyrosine and phenylalanine are as effective for depression as some antidepressant drugs, and that depressed patients had low levels of phenylalanine in their body.
