Tryptophan

Tryptophan

Tryptophan is the least plentiful of all 22 amino acids and an essential amino acid in humans (provided by food). It is found in most proteins and a precursor of serotonin. Tryptophan is converted to 5-hydroxy-tryptophan (5-HTP), converted in turn to serotonin, a neurotransmitter essential in regulating appetite, sleep, mood, and pain. It is a natural sedative and present in dairy products, meats, brown rice, fish, and soybeans.

Helps your body to:

produce serotonin, which may improve mood
support relaxation
sleep well
promote the body's own natural melatonin without the addition of hormones

Protect and effective against:

mood swings
insomnia
stress
a reduced memory performance

Deficiency symptoms:

Inadequate dietary protein intake can contribute to a deficiency of tryptophan. Since it is an essential amino acid, tryptophan deficiency may cause symptoms mirror those of protein deficiency. These include weight loss and impaired growth in infants and children. As insufficient dietary intake of tryptophan can lead to low serotonin levels, deficiency can lead to neuropsychological symptoms including depression, anxiety, irritability, impulsiveness, inability to concentrate, poor dream recall and insomnia. Other associated symptoms include carbohydrate cravings, overeating and weight gain.

Overdose symptoms:

A tryptophan overdose can cause a condition known as eosiniophilia-myalgia syndrome, which can cause severe muscle pain, nerve pain, hair loss, fatigue, a rash, dry skin and high levels of a type of immune cell known as eosinophils. A tryptophan overdose can also cause serotonin syndrome, which can result in confusion, hallucinations, muscle spasms, trouble walking, increased sweating, fever, rapid heartbeat, faintness and diarrhea.
