Amino Acid Supplements for Depression

L-Tyrosine, L-Tryptophan, D L-phenylalanine and gamma aminobutyric acid are important amino acids associated with depression. Supplementation of these amino acids along with other forms of treatment can quicken the process of treatment. Certain antidepressant drugs can be avoided by supplementing them with amino acids. Amino acid supplements when taken along with other treatments like psychotherapy are highly helpful.

L- Tyrosine: Norepinephrine is an important biogenic amine in neurotransmission and deficiency in it can result in the lack of response to certain antidepressant drugs. The amino acid L- Tyrosine stimulates the production of norepinephrine. It is also ideal for reducing the excessive fatigue experienced by some depression patients. The amino acid supplement L-Tyrosine is usually taken along with B-complex vitamin, which allows the body to metabolize the amino acid.

D, L-phenylalanine: Supplements of phenylalanine is highly helpful in reducing severe forms of depression. The amino acid is metabolized to phenylethylamine (PEA). PEA normally occurs in the brain and is associated with mood. Deficiency of PEA is seen as cause for depression. D-phenylalanine is not widely available and to produce the supplement a mixture of D-phenylalanine and L-phenylalanine is used. The amino acid has the effect of an antidepressant drug and is taken along with vitamin B6.

L-Tryptophan: Supplements of amino acid L-Tryptophan improves the levels of serotonin and melatonin. There are two opinions regarding the use of this amino acid in the treatment for depression. It is used along with vitamin B6 and vitamin B3. 5-HTP is considered to be equally effective as L-Tryptophan.

Gamma Aminobutyric Acid: It is an amino acid found in the central nervous system and it acts as an inhibitory neurotransmitter. Depressed people are found to have low levels of this amino acid.

Black beans, soybeans, eggs, skimmed milk, cheese, tofu and yoghurt are important sources of amino acids. Numerous amino acid supplements are also available. Amino acid supplements should be followed by a vitamin supplement. The advice of a therapist should be taken regarding the dosage of the amino acid supplement and the following vitamin supplement.
