We Want You to Ask Questions

Seriously. Our team of supplement experts and scientists has answers.

We go above and beyond when it comes to testing, because we believe you deserve to know what you’re putting in your body and why. Third-Party testing every batch of Sleep BioSeries™ Melatonin isn’t a requirement, but at Ritual we think it should be. Your peace of mind is our priority, which is why we do our own rigorous testing on each batch.

Each batch of Sleep BioSeries™ Melatonin is tested for identity and dose so we can be sure that what’s on the label is what’s in the capsules. We also complete Third-Party testing to ensure our products are compliant with regulations and guidelines for heavy metals and microbes and to help assure the quality and safety of our products.*
Take Sleep BioSeries™ Melatonin one hour before bedtime. The formula is designed to release for about six hours, so try to aim for at least 7-8 hours of sleep for the best experience.
The world’s first BioSeries™ three-in-one tablet in capsule technology is a breakthrough innovation designed to optimize our formula delivery through customized release profiles. For Sleep, BioSeries™ technology combines 5mg of instant and extended release Melatonin designed with the body’s Melatonin release in mind. Melatonin releases in phases to support falling asleep and staying asleep to wake up rested.*
We always seek out ingredients that are backed by clinical studies and have extensive research. We formulated this product with 5mg of melatonin because our scientists found that this dosage is backed by decades of clinical research and has been shown to support a good night’s sleep. Higher doses aren’t necessarily better, and that’s why our scientists formulated with 5mg of instant and extended release Melatonin to help fall asleep, stay asleep, and support restful sleep.*
