Tryptophan: Top Benefits for Toronto Functional Medicine Patients

When you hear about tryptophan, do you think about turkey dinners in your Toronto home? Well, you’re on the right track! From the view of naturopathic integrative functional medicine, let’s discuss what tryptophan is and its key benefits for reaching optimal health.

What is Tryptophan?

Tryptophan is one of the amino acids the human body uses for protein biosynthesis. It’s essential because your daily life needs tryptophan for supporting muscles, neurotransmitters and enzymes.

Unfortunately, the body can’t create this amino acid by itself, so we need to find healthy sources of it. Tryptophan can be consumed through dietary supplements and food sources (i.e. bananas, peanuts and turkey). (Don’t worry, if you have dietary intolerances or concerns, a functional medicine practitioner can help you out.)

Studies have suggested that tryptophan could positively affect mental health and cognition. According to an article in the International Journal of Tryptophan Research, tryptophan can “change the rates of serotonin synthesis in the brain.” So how exactly does tryptophan impact health and your personalized medicine plans? We explain below:

Benefits of Tryptophan for Toronto Functional Medicine Patients

1. Tryptophan may improve sleep.

Sleep is crucial for our everyday lives. A study on adults aged 55-75 years old showed that tryptophan could enrich sleep for seniors. Participants were given cereals that contained tryptophan, which led to enhanced sleep efficiency and lowered sleep latency.

2. May promote anxiety relief.

In the same study, participants had improvements to their anxiety/depression symptoms after eating tryptophan-rich cereals. But tryptophan may also impact other age groups in reducing anxiety. In another study, university students were given high-tryptophan or low-tryptophan diets. Students who ate high levels of tryptophan experienced less depression and anxiety compared to those who ate low amounts of tryptophan.

3. Tryptophan may help ease PMS and PMDD symptoms.

Tryptophan is a precursor to serotonin, which may aid in the symptom management of PMS and PMDD (i.e. mood swings). In a study of women, a lack of tryptophan was shown to increase irritability during PMS and PMDD: “Symptom magnitude was correlated with diminution of tryptophan relative to other amino acids. This result supports other evidence implicating serotonin in premenstrual syndrome,” reported a Journal of Affective Disorders article.

4. Could help with nicotine withdrawal symptom management.

Tryptophan may help with quitting smoking. In a study published in the Journal of Behavioral Medicine, “Tryptophan-treated subjects who could not fully abstain were able to smoke fewer daily cigarettes. Reported anxiety and other withdrawal symptoms were lower in the tryptophan group compared with control subjects.”
