What is L-Tryptophan?
L-tryptophan is an amino acid. Amino acids are protein building blocks. L-tryptophan is called an "essential" amino acid because the body can't make it. It must be acquired from food.
People use L-tryptophan for some mental health disorders, to help quit smoking, for athletic performance, and for emotional symptoms in people with premenstrual dysphoric disorder (PMDD), but there is no good scientific evidence to support many of these uses. There is also concern that using L-tryptophan might cause a condition called eosinophilia-myalgia syndrome (EMS).
L-Tryptophan Benefits
One of the key benefits of Tryptophan is that it may help to decrease appetite and reduce symptoms of depression and anxiety. Studies have shown that low levels of Tryptophan in the body may lead to anxiety disorders and depression.
It has also been shown that the Serotonin resulting from Tryptophan has a limiting effect on appetite and may help to reduce caloric intake and weight in obese people. Tryptophan is further used to synthesize Niacin, which is used in the processing of carbohydrates and fats.
Tryptophan supplementation may also encourage healthy sleep patterns. These benefits seem to be directly related to the release and synthesis of Serotonin and Melatonin. Tryptophan is capable of maintaining a fairly consistent level of Serotonin throughout the day and aids in the production of the proper level of Melatonin at night.
This makes Tryptophan distinct from the other well-known Serotonin precursor (and Tryptophan metabolite), 5-HTP. When ingested orally, 5-HTP is not subject to any rate-limiting factors, which means there is no control on how high Serotonin levels may go.
Consequently, Tryptophan's effects may be less noticeable than 5-HTP, but with potentially fewer side effects.
There are a number of medical conditions which Tryptophan is able to improve. A 2010 study showed that Tryptophan may halt the spread of a common liver condition known as steatohepatitis.
Tryptophan may also be capable of improving conditions associated with irritable bowel syndrome (IBS). It has been shown that the less Tryptophan a person has in their body, the more serious the symptoms of this condition can be.
L-Tryptophan Mode of Action
Tryptophan is a precursor to a number of different hormones, neurotransmitters, and other substances throughout the body.
As this supplement travels through the bloodstream it aids in the production or synthesis of various proteins. Tryptophan is a precursor for Niacin, a B vitamin with several positive effects on the brain. Tryptophan is also used to make Serotonin, an important neurotransmitter.
Tryptophan is broken down in the liver into the compound 5-HTP and other metabolites. The 5-HTP travels through the bloodstream to the brain, crosses the blood-brain barrier, and enters the brain. Once in the brain, the 5-HTP is converted into Serotonin.
Serotonin is known as the "happiness neurotransmitter," because the presence of Serotonin in the brain is associated with positive emotions including happiness, peacefulness, and calm.
Tryptophan being a precursor for Serotonin is an important function in itself, but it also leads to a number of additional effects. Serotonin is thought to help regulate things like appetite and mood. Some Serotonin is also converted to Melatonin, the hormone which regulates sleep/wake patterns (circadian rhythm).
L-Tryptophan Dosage
As with most supplements, the dosage you take will be determined by your specific purpose or condition. For this reason it is advised to consult with your doctor or qualified medical professional before beginning use.
Some sources indicate that the most commonly used dosage range is between 6 and 12 grams.
Most adults (especially those who are looking to reduce symptoms of depression) will take Tryptophan supplements in 3 or 4 equally divided daily administrations to ensure a consistent supply.
