5-HTP 200 mg Sleep Quality Study

 

 

Study of Self-Reported Quality of Sleep in Healthy Adult Volunteers Taking a Dietary Supplement Containing 5-HTP, Glycine, Taurine, Inositol, Niacinamide and Pyridoxine.

Thirteen healthy adult volunteers (11 males and 2 females, 25-55 years old) successfully completed a series of online surveys related to the quality of sleep. The study was conducted in two phases.

During the first phase, the surveys were completed for five consecutive days without supplementation. In the second phase, the identical surveys were completed while taking a dietary supplement containing 200 mg 5-HTP from Griffonia simplicifolia (plus complementary nutrients glycine, taurine, inositol, niacinamide, and pyridoxine), administered one hour prior to bedtime, for five consecutive nights. The surveys were completed on the days following supplementation.

The study was not blinded. Rather, the study was designed to collect a self-reported data from the volunteers fully aware of the nature of the supplement they were taking. Upon completion, the results were collected and analyzed for the following:

  • Time to fall asleep; in minutes (see Figure 1).
  • Number of times the person remembered waking up during sleep (see Figure 2).
  • Self-reported level of feeling rested upon waking up (see Figure 3).
  • Self-reported level of energy during the day following the supplementation (see Figure 4).

Conclusion: The results of the study indicate that volunteers had a positive experience with the dietary supplement containing 5-HTP. The highlights of the study were an improved feeling of being rested upon waking up, and an increased energy level during the day following the supplementation.
