- There are reports that taking GABA and rafuma (AVLE) has a positive effect on sleep quality.
- The evidence score is 37, indicating that the reliability is limited.
- This information is relevant to adults who want to check their sleep status using objective indicators.
Rafuma is something that has been the subject of research related to sleep quality.
It is generally used in the context of examining the effect of a specific intake on sleep.
Rafuma (Apocynum venetum Leaf Extract) is an extract derived from the leaves of a plant. In the research, it is referred to by the abbreviation AVLE. There is a study reported in 2015 on the effect of this ingredient on sleep.
This study investigated how elements contained in the rafuma leaf extract are related to sleep. Exploring what kind of response a specific substance produces in the body is an important process in sleep research.
There are reports that taking GABA and rafuma (AVLE) may have a positive effect on sleep quality. This is a result shown through the measurement of brain waves.
This study was conducted on adults. Specifically, it examined the effects of taking 100mg of GABA and 50mg of AVLE, an extract of rafuma. Through comparison, the study confirmed how taking these ingredients relates to sleep status.
As a technical method, a randomized controlled trial (a reliable research method in which participants are randomly assigned to compare effects) design was used. In other words, this is an attempt to objectively verify the effect that specific conditions have on the results. In addition, sleep status was measured using an EEG test with an electroencephalograph (a device that measures electrical activity in the brain from the scalp).
The evidence score presented in this article is 37, and the reliability is considered limited. This is an evaluation based on the scale and number of studies.
There are several reasons for reaching this conclusion. Since this report is based on data from only 1 study, there is still insufficient information to generalize the results. In addition, detailed conditions such as the number of participants are also considered limited.
In the world of scientific research, even if a good result is obtained in one trial, it is avoided to draw a conclusion based on that alone. This is because it is necessary to confirm whether the same result can be reproduced for many people under different circumstances. Therefore, at this point, it cannot yet be said to be "certain." Since it may not suit everyone, it is best to regard this for now as a single research report.

The subjects of the research are adults. The number of subjects is not stated.
This can serve as material for considering whether it applies to your own situation, based on the attributes of the subjects.
This research is based on 1 study report using a randomized controlled trial (RCT).
The reliability of the research is reported to be limited.
Since detailed figures such as the number of subjects are not stated, caution is needed in interpreting the results.
What effect is rafuma reported to have on sleep?
A1: Research has reported a positive effect on sleep quality. This is research on sleep quality.
What method was used in the rafuma research?
A2: The research was conducted using a randomized controlled trial (RCT) method. This is one type of research design.
How reliable are the rafuma research results?
A3: There is 1 study. The reliability is reported to be limited.
There is 1 research report indicating that taking rafuma (AVLE) and GABA has a positive effect on sleep quality. However, it should be noted that the evidence score is 37, and the reliability is limited. Since the number of studies is still small, further investigation is expected in the future.
Why not start by doing a self-check on your own sleep condition?
