Jigsaw L-Tryptophan is being presented as a dietary supplement capable of promoting healthy serotonin levels in brain and can also sustain the quality of sleep.

The United States company that stands behind this product is called Jigsaw Health and is a father and son developed business that operates in Arizona and was established in 2005. Their main focus is to provide their customers with unique and potent blends that are made using special techniques that offer them an advantage next to other supplements available on the market. One of the methods of setting their product apart is by using a Sustained Release Technology, which is capable of making the active ingredients have a longer release time and thus can be properly assimilated by the system. These claims of quality are currently backed up with a money back guarantee that is available for 90 days.

Jigsaw L-Tryptophan has many therapeutic uses, such as aiding in serotonin production, sustaining a restful sleep, promoting mental and emotional well being and is also said to support weight management. The manufacuterer presents Jigsaw L-Tryptophan as being suitable for vegan and vegetarian use as well, because it does not have any ingredients that come form animal sources.

Jigsaw L-Tryptophan Ingredients

Jigsaw L-Tryptophan contains the following ingredients: L-Tryptophan (Amino Acid), Vegetable capsules, and Vegetable stearic acid.

Product Features

Jigsaw L-Tryptophan is an amino acid based dietary supplement blended around the purest form of L-Tryptophan available.

The only active ingredient present in this porduct is an essential amino acid that is called L-Tryptophan and cannot be naturally produced in the body, thus the needed levels have to be sustained by consuming food that is rich in this amino acid or by using dietary supplements like this one. This ingredient also presents itself with a number of therapeutic qualities that mostly regard the nervous system; thus this substance is said to be effective with health issues like: anxiety, depression, and insomnia or attention deficit-hyperactivity disorder. Some people also use this amino acid in weight management programs because it’s said to regulate appetite. The most relevant effect of this ingredient is the one it has over mood, this substance being the natural precursor of serotonin, which is a neurotransmitter that has been linked with the state of well being. The use of this amino acid during the period of pregnancy and breast feeding has been determined of being harmful to the child and we highly advise against it.

This formula is available in two forms, one that provides a month supply and presents itself with a bottle that holds 60 vegetarian capsules and the other that hold 120 and provides a two month supply.

    I like this product, it’s easy to take and very effective. Before I started taking these, I hadn’t gotten a good night’s sleep in years. On the 3rd day of treatment, I fell asleep watching the tv around 8 pm and didn’t wake up until morning. In case you’re wondering, yes, I have a tv in my bedroom. I know it’s against all feng shui rules, but it helps pass the time when I can’t sleep. Now that I sleep a lot better, I hope I won’t be needing it anymore.
