Sleep BioSeries™ Melatonin combines instant release and extended release for all night sleep support.*
In a dissolution test, two instant release competitor products released all of their melatonin within 1-1.5 hours. Ritual’s Melatonin released melatonin over the course of 6 hours for all night sleep support, designed with the body’s melatonin release in mind.*
Dissolution is the rate and extent at which a substance forms a solution. A dissolution test is an industry standard (we follow the USP procedure) for understanding the release characteristics of a capsule, a tablet, or in this case, BioSeries technology. This test was conducted in partnership with USPL, one of our collaborators in developing release technologies.
We are incredibly proud of the evidence-based products we formulate, and we believe scientific studies are the best way to quantify an ingredient’s impact.
