Sleep better naturally

Your best days begin with a good night’s sleep.

If difficulty falling asleep or staying asleep, or tossing and turning are part of your nightly sleep experience, your body is missing out on the rest and recovery it needs.

Sleep latency (how long it takes you to fall asleep), duration (the length of time you’re asleep throughout the night), and restfulness (the quality of your sleep) are the three most important factors that contribute to a good night’s sleep.

And each of these factors is affected by two key neurotransmitters: GABA and serotonin.

Kion Sleep naturally supports your GABA and serotonin function with three amino acids that work with your body’s own sleep system to promote a deep, restful slumber:

  • Gamma-aminobutyric Acid (as PharmaGABA) reduces stress, promotes relaxation, and improves the quality of your sleep.
  • L-theanine elevates levels of the neurotransmitters GABA, serotonin, and dopamine. Increasing levels of these calming brain chemicals promotes relaxation and can help with sleep.
  • L-Tryptophan is converted to the sleep-regulating neurotransmitter 5-hydroxytryptophan (5-HTP), which then works to increase levels of the calming neurotransmitter serotonin, as well as the sleep-signaling hormone melatonin.

When taken together, these three amino acids work naturally in your body to give you a deeper, more restful night’s sleep.
