## Features

- Tired of Tossing and Turning - Kavinace OS is a neuro immune support supplement designed for those who require quick relief from sleeplessness. Just one night of poor sleep may trigger an overactive immune system to keep you awake, which is why this calming sleep aid takes a comprehensive approach to evening relaxation.*
- The Immune x Sleeplessness Connection - Poor sleep can disrupt cellular metabolic function. The Kavinace OS sleep supplement combines L theanine with antioxidants and minerals to intervene at every point in the Immune-Sleep Cycle, and break unhealthy patterns.*
- Less Waiting, More Sleeping - We formulated these dual-action immunity support sleep aids for adults who need a formula that can help calm their body down before bed, so they can fall asleep faster. Low dose melatonin combines with Zinc and Astaxanthin, which have been shown to significantly decrease time of sleep onset.*

Eight out of ten participants said they were "satisfied" or "very satisfied" with how quickly they fell asleep.*
