Melatonin keeps the body’s circadian rhythm (natural sleep cycle) in check. It tells us when it’s time to rest and when it’s time to wake up. It relaxes the body and improves your sleep quality. Microdosing Melatonin is now a popular way to improve cognitive function and health. Microdosing means taking a tiny dose of the compound, far below the “typical” to induce sleep. Hence, you reap the benefits without having to fall asleep right after. Which could be a drawback in this context.
