L-Tryptophan and its Health Benefits

The health benefits associated with tryptophan include help with anxiety, depression, depressed mood, insomnia, and even weight loss in obese dogs.


For the body to make serotonin, an ample amount of tryptophan is needed. Tryptophan is an amino acid, which has been studied for many years and has helped scientists understand the impact that serotonin has on behavior and psychological health. Typically after l-tryptophan gets access inside the brain, the essential amino acid is converted into 5 hydroxy tryptophan (5 HTP), and finally serotonin. Research shows that low levels of tryptophan, is directly correlated to low production of brain serotonin, and has been shown to impact stress, anxiety, mood, memory impairment, aggression, and depression.


The neurotransmitter serotonin is responsible in memory and learning brain functions. Additionally, serotonin controls mood and appetite. The passageway to the brain is the blood brain barrier. The blood brain barrier is the gatekeeper for substances that will be passed on to the brain through the blood. Tryptophan, when compared among other amino acids in protein usually occurs in the least amounts, so it has a tougher chance of making it through the blood brain barrier as the other amino acids are greater in quantity. Following the conversion of tryptophan into serotonin, melatonin is made from serotonin. Melatonin is the hormone that regulates sleep cycles.


Finally, tryptophan is converted by the body into niacin, which is a B vitamin, and is critical in the metabolic process of converting food into usable energy as well as keeping a healthy nervous system. A diet that does not supply enough of tryptophan results in a niacin deficiency. Toxicity with tryptophan has not been shown, even in extremely high doses, and supports the claim that there have been no side effects associated with tryptophan. Thunder Chews Calming Support contains the necessary tryptophan that your animal needs.
