Discovered in the early 1900s from the milk protein casein, L-tryptophan is an essential amino acid with several alternative names. Understanding what is L-tryptophan also known as is key to recognizing its presence in supplements and scientific literature. This vital nutrient serves as a precursor to several important compounds in the human body, influencing mood, sleep, and overall well-being.

Tryptophan was first isolated from the milk protein casein in 1901 by British biochemists Frederick Gowland Hopkins and Sydney W. Cole. Another name for tryptophan, such as L-tryptophan or its IUPAC chemical name, provides important context for this essential amino acid's biological and scientific roles.

The human body cannot produce L-tryptophan, an essential amino acid that must be obtained through diet. Despite this reliance, it is not the same as niacin, though it can be used to produce it in a complex metabolic process.

Despite the persistent myth, one medium banana contains a relatively small amount of L-tryptophan—around 11 milligrams—especially when compared to other common foods. This article investigates the science behind the claim, exploring whether the presence of this amino acid is significant enough to impact mood and sleep.

Tryptophan is an essential amino acid that the human body cannot produce on its own, making dietary intake vital for creating mood-regulating serotonin and sleep-inducing melatonin. Fortunately, many diverse plant-based foods contain L-tryptophan, allowing individuals to naturally support their mental and physical well-being through diet.

According to scientific research, the amino acids L-tyrosine and L-tryptophan serve as precursors for different key neurotransmitters in the brain, meaning neither is definitively "better" than the other, but rather suited for different purposes. Understanding which is better, L-tyrosine or L-tryptophan, depends entirely on the specific health benefits you are seeking to achieve.

Studies have shown that L-tryptophan supplementation can reduce the time it takes to fall asleep by approximately 15–30 minutes for individuals with mild insomnia. This essential amino acid is a precursor to crucial neurotransmitters like serotonin and the sleep-regulating hormone melatonin, impacting both mood and sleep quality.

According to a 2016 review of studies, the essential amino acid tryptophan promotes good sleep and a good mood, but the myth that eating turkey will make you immediately drowsy is not so straightforward. While tryptophan is a precursor to sleep-regulating hormones like serotonin and melatonin, the presence of other amino acids in food limits its impact.

One large egg contains approximately 77 to 83 milligrams of L-tryptophan, a vital amino acid that your body cannot produce on its own. This amount contributes significantly to your daily intake and aids in the production of serotonin and melatonin, which are crucial for regulating sleep and mood.

L-tryptophan, an essential amino acid, is known to influence mood and sleep. However, it's crucial to understand who shouldn't take L-tryptophan to avoid serious health complications, such as serotonin syndrome and drug interactions.
