If you are suffering from severe sleeping issues, we recommend seeking advice from a physician or medical professional. However, it is worthwhile to try a natural product such as Rilax. A recent clinical study published in The Open Sleep Journal (2009;2) showed that Rilax’s active ingredient, Alpha S1-Casein Tryptic Hydrolysate, helped a majority of participants to fall asleep faster, as well as significantly improve various aspects of sleep disorders. Results indicated improvement in sleep quality after two weeks of supplementation, along with decreases in sleep latency and daytime dysfunction after four weeks of supplementation.
