Melatonin + 200mg L-theanine is a supplement aimed at facilitating and improving sleep. Many individuals find it difficult to maintain healthy sleeping habits, mostly due to stress, busy schedules or medical conditions. This supplement is meant to relax the mind and regulate sleep cycles, so that people taking it can benefit from a good night’s sleep. As opposed to many supplements that contain Melatonin, this one also contains various herbal extracts and amino acids that are meant to help relax the brain and alleviate stress.

This product is manufactured under the brand name Nature Made, the most popular of the three brands owned by Pharmavite. This company has been operating in the health supplement industry for nearly 40 years and is considered one of the top names in the field, due to the high quality standards that it holds.


1) Quick Overview

Melatonin + 200mg L-theanine is based on a mixed formulation of ingredients; it contains the amino acid L-Theanine, herbal extracts and Melatonin, a hormone that can be produced synthetically, but is also found in the human body. The purpose of this ingredient combination is promoting better sleep.

Melatonin is supposed to facilitate sleep, not by inducing relaxation but by regulating sleep cycles, making the body feel the need to rest at the hours each individual decides. Unfortunately, this effect might only take place in certain individuals, as medical research is still researching the full effect of melatonin supplements.

L-theanine is an amino acid that is able to cross the blood-brain barrier and is believed to reduce stress and boost mood. Its purpose in this formulation is to promote mental relaxation in order to promote better rest, along with the herbal extract that are also incorporated in the formula.


2) What Are Melatonin + 200mg L-theanine Ingredients?

Melatonin + 200mg L-theanine contains the following ingredients: L-Theanine, Melatonin, Chamomile Flower Extract, Passion Flower Extract, Lemon Balm Leaf Extract, Medium Chain Triglycerides, Gelatin, Glycerin, Soy Lecithin, Water, Yellow Beeswax, Maltodextrin, Titanium Dioxide, and artificial color (Blue 1, Red 40, and Yellow 6).

3) What Does Melatonin + 200mg L-theanine Do?

Melatonin + 200mg L-theanine is a combination of several ingredients known to induce a feeling of relaxation and sleepiness, the most potent being Melatonin and L-Theanine.

Melatonin is a hormone naturally produced in the brain of most mammals by the pineal gland. This substance is produced during darkness and then immediately enters the bloodstream producing a feeling of sleepiness. To prevent certain diseases or complications, only synthetic melatonin is used in the production of dietary supplements. Although in theory supplemental melatonin should act as a sleep-aid, the results of several clinical trials do not agree with one another. While some studies could not find results above placebo, others showed that supplemental melatonin reduced the time in which an individual fell asleep by an average of 4 minutes. It appears that the quality of the melatonin used in a certain supplement significantly affects its effectiveness.

In addition to melatonin, the manufacturer also included L-Theanine, an amino acid shown to promote deep muscle relaxation. Although researchers do not fully understand the mechanism of action of L-Theanine, current research has focused on its ability to cross the blood-brain barrier and its effect on the brain transmitters and brain waves. A recent study concluded that one way in which it promotes relaxation in humans is by increasing alpha brain waves.

For best results, take one soft gel of Melatonin + 200mg L-theanine daily.
