Zephyr is a comprehensive blend of research-proven ingredients designed to support better sleep quality and the body's nighttime repair process, so you wake up refreshed and prepared for tomorrow, without melatonin. It works by helping to restore the gut-brain balance and signal the mind and body to unwind, recover and rebuild overnight.*

Many people notice benefits on the very first night. zephyr combines ingredients that work on different timelines to support both immediate relaxation and long-term sleep health.*

Some ingredients begin working within 30–60 minutes to help calm a busy mind, ease stress, and prepare your body for sleep, making it easier to unwind and fall asleep naturally.*

Other ingredients work more gradually over several hours - and continue working for days to weeks - by supporting healthy stress regulation, the gut-brain axis, and your body's natural sleep architecture. These ingredients help you stay asleep longer, improve sleep quality, and wake feeling more refreshed and restored.*

While everyone's response is different, the best results typically come with consistent nightly use for at least 2–4 weeks, allowing both the fast-acting and long-term ingredients to work together to optimize your sleep.

As a dietary supplement, mix one stick of powder with chilled or sparkling water. Sip and enjoy.

No, zephyr does not contain melatonin. Instead, it's formulated with natural ingredients to improve sleep architecture for a deeper and more restorative sleep, so you wake feeling refreshed.*
