How it works

• Deep & Restorative Sleep
  

Many common sleep aids and alcohol shorten the time it takes to fall asleep but suppress the deeper stages of sleep, which is why falling asleep quickly doesn’t always translate to waking up rested. Sleepbiotic is built to support the sleep stages themselves. A deliberately low 1 mg dose of plant-derived melatonin cues the body’s natural “lights out” signal to ease sleep onset without oversaturating melatonin receptors the way higher doses can. L-theanine, glycine, and GABA work through complementary pathways, raising inhibitory neurotransmitter activity and gently lowering core body temperature to help the nervous system settle into deeper, more restorative sleep. With continued use, CP2305 supports healthy sleep patterns through the gut-brain axis.

In a 24-week, placebo-controlled study of 60 medical students under chronic academic stress, daily CP2305 significantly reduced sleep disturbances. Overnight EEG showed participants fell asleep faster, spent less time awake after sleep onset, and reached a greater proportion of deep, slow-wave sleep in their first sleep cycle. These findings support CP2305’s role in healthy sleep patterns. Sleepbiotic builds on this clinical foundation by pairing CP2305 with complementary sleep-supporting nutrients. A low dose of melatonin helps support natural sleep onset while minimizing next-day residual effects, while glycine provides additional support for deeper, more restorative sleep. Together, these ingredients create a more complete approach to falling asleep, staying asleep, and improving overall sleep quality.

• Stress and Fatique Support

Chronic stress can keep cortisol elevated into the evening, which can interfere with both falling asleep and reaching deep sleep. Poor sleep, in turn, can leave the body more reactive to stress and more fatigued the following day. Breaking that cycle means supporting a calmer nervous system during the day, not just at bedtime. Sleepbiotic works on two timelines to do this. In the moment, L-theanine helps raise GABA and glycine activity in the brain, while GABA itself has been shown to produce measurable calming shifts in brainwave activity. Together, they help take the edge off stress without causing drowsiness. Over time, CP2305 works through the gut-brain axis to support a healthier stress response.

In the same 24-week study, daily CP2305 also significantly reduced anxiety and lowered chromogranin A, a salivary marker of stress. Separate CP2305 research has shown reductions in cortisol and a shift toward a calmer nervous system state. These stress-related benefits are associated with continued use, supporting a steadier response to daily stress over time.

Ingredients: Lactobacillus Gasseri CP2305, Plant-Derived Melatonin, GLycine, L-Theanine, and Gaba

Directions: For occasional sleeplessness, take 2 capsules 30 to 60 minutes before bedtime. If additional support is needed, one additional capsule may be taken. Do not exceed 3 capsules per day.
