What is tryptophan?

Tryptophan is an amino acid that affects serotonin and melatonin levels in the brain. What makes tryptophan so unique, compared to other brain supplements, is how many areas of the brain it may affect. Studies show that this amino acid could play a role in not only relieving depression but also improving memory, resulting in reduced irritability and anxiety and higher-quality sleep.

Tryptophan is found naturally in whole milk. Other good sources of tryptophan are tuna and turkey; however, meat and dairy are not the only sources of this amino acid. For vegans and vegetarians looking to find natural sources of tryptophan, greens such as broccoli and peas are also good sources. Research shows that pumpkin and sunflower seeds also have a good amount of tryptophan.

While many foods contain tryptophan, getting the daily requirements for a healthy lifestyle can be a struggle for those with busy schedules. This is why finding the best tryptophan supplement makes it easier to achieve improved cognitive function.
