Frequently Asked Questions
Supersleep is a melatonin-free nightly sleep support drink designed to help you fall asleep faster, sleep deeper, and wake up feeling refreshed.*
It combines clinically studied ingredients like L-Glycine (3,000mg), Maizinol™, KSM-66® Ashwagandha, Magnesium Glycinate, L-Theanine, and GABA to support your natural sleep cycle without dependency.*
Melatonin is a hormone, and supplementing it can disrupt your body's natural production over time. Supersleep takes a different approach by supporting the pathways that help your body produce its own sleep signals naturally, so you get better sleep without creating dependency.*
It's a naturally sweet peach flavor that tastes like a treat before bed. Mix with 8-16 oz of water and enjoy 30 minutes before sleep. No artificial flavors, no sugar, no chalky aftertaste.
Many customers notice a difference the first night. The calming ingredients like L-Theanine and GABA work quickly to help you relax. For the full cumulative benefits of ingredients like Maizinol and KSM-66 Ashwagandha, give it 2-4 weeks of consistent use.*
