Tart Cherry & Sleep Optimization: The Science Behind Deeper, Restorative Sleep

Flowever is a supplement brand founded by Daniela Cyrulin and focused on longevity and healthspan for adults 40+. Its formulas are built around natural ingredients with research behind them and informed by her clinical experience.

Flowever's first product is Sleep Flow, created to support a nighttime wind-down routine.

Sleep Flow is a thoughtfully formulated, multi-ingredient nighttime supplement designed to support relaxation and healthy, restful sleep.

Its carefully selected formula combines Montmorency tart cherry concentrate, L-theanine, lemon balm, passionflower, chamomile, and sage in a melatonin-free formula.

Rather than relying on a single ingredient, Sleep Flow takes a multi-ingredient approach to supporting your nightly sleep routine.

No. Sleep Flow does not contain added melatonin.

Instead, the formula combines Montmorency tart cherry concentrate, L-theanine, lemon balm, passionflower, chamomile, and sage to support relaxation and healthy sleep as part of your nightly routine.

Sleep Flow takes a multi-ingredient approach to sleep support — without adding supplemental melatonin.

Each serving of Sleep Flow contains:

• 430 mg Montmorency tart cherry concentrate
• 150 mg L-theanine
• 200 mg lemon balm extract
• 150 mg passionflower extract
• 100 mg chamomile extract
• 5 mg sage extract
• 5 mg fennel seed extract
  

The ingredients were selected based on their individual research backgrounds and traditional uses related to relaxation and sleep support.

Sleep involves multiple biological and behavioral processes, so Sleep Flow was designed as a multi-ingredient formula rather than relying on a single compound.
The ingredients have different research backgrounds related to relaxation and sleep support.

Montmorency tart cherry naturally contains melatonin and other bioactive compounds, including anthocyanins. Some clinical research has found potential improvements in sleep-related outcomes with tart cherry preparations, although results across studies are not completely consistent.

Sleep Flow provides 430 mg of Montmorency tart cherry concentrate per serving.

L-theanine is an amino acid naturally found in tea that has been studied for relaxation and sleep-related outcomes. Research suggests that it may support subjective sleep quality and sleep onset in some populations.

Sleep Flow provides 150 mg of L-theanine per serving.

Sleep Flow takes a different approach from melatonin alone.

Melatonin supplements provide supplemental melatonin directly. Sleep Flow does not contain added melatonin. Instead, it combines Montmorency tart cherry concentrate, L-theanine, and a carefully selected blend of calming botanicals designed to support relaxation and healthy sleep.

Rather than relying on a single ingredient, Sleep Flow takes a multi-ingredient approach to your nightly sleep routine.
