What is tryptophan?
Tryptophan is an essential amino acid, meaning, first and foremost, that it’s one of the building blocks of proteins. Simply put, the human body uses amino acids to make proteins to help the body with all kinds of functions including: creating tissues, forming antibodies, forming red blood cells, and many others.
Tryptophan is one of the most important essential amino acids for the production of the neurotransmitter serotonin (also known as the happy chemical) and the production of the hormone melatonin (also known as the sleep chemical)Tryptophan.
When tryptophan metabolizes, it forms a compound called 5-HTP (5-Hydroxytryptophan). 5-HTP is necessary for the production of serotonin, which is necessary for the production of melatonin. ACCURATE EDUCATION – L-TRYPTOPHAN & 5-HTP (5-HYDROXYTRYPTOPHAN) Here’s a representation of the process:
Steps to create serotonin through tryptophan:
Tryptophan —► 5-Hydroxytryptophan (5-HTP) —► 5-Hydroxytryptamine —► Serotonin
Steps to create melatonin through tryptophan:
Tryptophan —► 5-Hydroxytryptophan (5-HTP) —► 5-Hydroxytryptamine —► Serotonin —► N-acetyl-serotonin —►Melatonin
Tryptophan can help you improve your sleep but to be really effective you must combine it with proper sleep hygiene.

When we travel to a new time zone, it often takes a couple of days to adjust to our new sleep schedules. All of a sudden, we have to get to sleep at what feels like a much earlier or much later time. That’s because, even though we’re in a new time zone, our bodies are still producing melatonin as if we’re in our old time zone. It takes a few days for our bodies to adjust to our new sleep schedule and produce melatonin at the right times.

Melatonin production is essential to be able to fall asleep quickly and to stay asleep throughout the night. If you have a hard time falling asleep and/or you find yourself waking up several times during the night, your body may be producing too little melatonin.
