Romansive Sleep Lab, the company behind COZA SLEEP, currently available on US Amazon, is expanding its sleep aid offerings with the upcoming launch of Natural COZA SLEEP, scheduled to debut in December this year. This new and enhanced version stands out by completely removing melatonin from its formula. While COZA SLEEP has been available to consumers, Natural COZA SLEEP introduces a fresh approach, providing all the sleep-enhancing benefits through 100% natural ingredients. This makes it a safer, non-habit-forming alternative, eliminating the potential side effects commonly associated with synthetic sleep aids. The new Natural COZA SLEEP will be available on Amazon following its launch.

The Science Behind Natural COZA SLEEP

Unlike over 90% of sleep aids in the U.S. market, which rely on melatonin and synthetic chemicals, Natural COZA SLEEP is formulated with scientifically proven plant extracts. One of its key components, rice bran ethanol extract (RBS), has been clinically shown to significantly reduce sleep latency by 33%, while increasing both total sleep time and sleep efficiency, with no reported serious side effects. This was demonstrated in a two-week, double-blind, placebo-controlled study involving 50 participants, highlighting its effectiveness in improving sleep quality.

Another standout ingredient is Angelica tenuissima, a traditional herbal remedy patented in Korea for its sleep-enhancing properties. Preclinical trials have shown that this extract increases overall sleep time. Additionally, probiotic-fermented jujube seeds further enhance sleep by increasing the levels of natural compounds that promote deeper rest. These ingredients work synergistically to activate essential neurotransmitters, such as GABA and 5-HTP, optimizing the body’s natural sleep processes.
Natural COZA SLEEP represents a significant advancement in sleep technology, providing a natural, non-habit-forming, and side-effect-free alternative to conventional sleep aids. With its groundbreaking ingredients, Romansive Sleep Lab continues to lead the way in sleep innovation, helping consumers achieve better rest and, ultimately, a healthier life.
