Fall asleep fast. Wake up refreshed.

Z4 Sleep is a professional-grade, non-addictive sleep support formula crafted by AAA Supplements to help you get a deep, uninterrupted night’s rest — without the morning grogginess common to traditional sleep aids.

🌙 Why Z4 Sleep Works:

  • PhGABA – A powerful GABA derivative that helps calm the brain by suppressing overstimulating neurotransmitters, enabling rapid and sustained relaxation.
  • 5-HTP – Supports serotonin production, improving sleep quality and mood. Additionally, it helps balance the HPA axis for enhanced stress resilience.
  • L-Theanine – Naturally found in green tea, this amino acid promotes alpha brain waves for a calm, meditative state without drowsiness.

🌟 Benefits:

  • Promotes deep, restorative sleep
  • Fast onset — fall asleep within 15 minutes
  • No sleep “hangover” or residual grogginess
  • Safe for occasional or regular use
  • Ideal for travelers, professionals, athletes, and anyone under stress

Z4 Sleep is ideal before big events, exams, travel, or simply for those who struggle to “switch off.” It’s the modern answer to sleepless nights — effective, gentle, and backed by research.

I have struggled to sleep since childhood and tried everything, including being prescribed sleeping tablets. Nothing worked, until I discovered z4. It has literally saved my life. I'm no longer sleep deprived and actually look forward to going to bed!! I recommend z4 to all my friends

2 of these per night and I'm out like a light. Crazy how effective this is....normally only sleep 3 hrs a night if I'm lucky, now up to 6.5-7. Best BEST product I've ever bought...please never go out of stock!!!
