What Is It?

L-Tryptophan is one of the most critical essential amino acids in the human body, being the biological precursor to serotonin, niacin and the hormone melatonin.

L-Tryptophan presents itself naturally in a number of high protein food sources including: red meat, chicken, eggs, seafood, dairy, nuts and in some supplemental protein powders.

2. What Does It Do?

L-Tryptophan works to regulate behaviours that involve serotonin signalling in the brain, including: mood, anxiety and improving sleep quality.

Specifically L-Tryptophan is transformed into 5 HTP when ingested allowing for maximum bioavailability, following this step 5 HTP becomes the major building block of serotonin production in the body; serotonin then generates a variety of physiological changes including sedation and calming.

Supplementing with L-Tryptophan has been shown to significantly decrease the time it takes to fall asleep, decrease total wakefulness and increase the total sleep time. Individuals who supplement with L-Tryptophan are likely to experience increased alertness and better cognitive performance the morning following supplementation. 

3. When Do I Take It?

 To take advantage of the relaxative and growth hormone properties of L-Tryptophan, it is best taken 30-45 minutes prior to sleep. Sleep Formula supplements containing L-Tryptophan should be taken at least 1 hour following your last meal of the day. The most efficacious dose is between 2000-3000 milligrams per serve.

4. How Long Does It Take To Work?

L-Tryptophan starts working as soon as it enters the bloodstream, which is typically 15 – 30 minutes after consumption. Users can expect to experience increased relaxation and sedation, within this time-frame.

5. How Much Does It Cost?

Sleep Formula supplements containing L-Tryptophan, range anywhere from $3.00 to $4.00 per serve, depending on the size and quality of the product. 

Based on an average price of $3.50 per serve, and based on five serves per week, supplementing with pre-workout products containing L-Tryptophan will typically cost around $60 per month.

6. What Are The Top Products?

We recommend using a Sleep Formula supplement such as Core Nutritionals ZZZ or Blackstone Labs Anesthetized. These products contain only the highest quality L-Tryptophan compound and are some of the best priced products on the Australian market.
