-
Maizinol®: A natural breakthrough that helps your body synchronize its own sleep-wake cycle.

Ingredients
CLEAN, FUNCTIONAL
Shoden® Ashwagandha (World's Most Bioactive Extract). Shoden® is a clinically studied, high-potency extract with a 35% withanolide glycoside content, making it far superior to standard extracts. It is specifically designed to: LOWER NIGHTTIME CORTISOL to help your body transition from "fight or flight" to "rest and digest" — REDUCE STRESS & ANXIETY by balancing the HPA axis — IMPROVE RESTORATIVE SLEEP quality so you wake up feeling physically and mentally refreshed. It provides significant support for energy levels and overall vitality without the heaviness of sedative-only formulas.
Suntheanine® (100% Pure L-Theanine). Suntheanine® is the most clinically studied and awarded form of L-Theanine, protected by over 40 patents worldwide. Unlike generic L-Theanine, it is produced via a patented fermentation process that mimics the natural compounds found in green tea. It is clinically proven to: INDUCE ALPHA BRAIN WAVES to create a state of deep relaxation without drowsiness — CALM THE RACING MIND by reducing the excitatory signals in your brain — IMPROVE FOCUS AND CLARITY upon waking, ensuring you feel alert and refreshed. It is the gold standard for achieving a calm, tranquil state before sleep.
GABA (Pharma-Grade Gamma-Aminobutyric Acid). GABA is the primary inhibitory neurotransmitter in the human brain, acting as a natural "off-switch" for mental chatter. Our high-purity GABA is specifically included to: QUIET THE NERVOUS SYSTEM by blocking specific signals in the central nervous system to reduce feelings of anxiety — ACCELERATE SLEEP ONSET by helping you fall asleep faster through immediate mental relaxation — SUPPORT EMOTIONAL BALANCE by preventing neurons from over-firing during times of high stress. It works in perfect synergy with L-Theanine to create a profound sense of tranquility without any habit-forming side effects.
Lemon Balm (Melissa Officinalis). Used for centuries as a natural calming agent, Lemon Balm is a botanical powerhouse that supports both the mind and the body. Our high-concentration extract is designed to: REDUCE ANXIETY-RELATED GASTROINTESTINAL DISCOMFORT by relaxing the digestive system, which is often where stress hits hardest — BOOST MOOD AND SEROTONIN by preventing the breakdown of neurotransmitters responsible for well-being — FACILITATE A GENTLE TRANSITION TO SLEEP without any sedative "knock-out" effect. It provides a soothing finish to our formula, ensuring that your body feels as relaxed as your mind.
Maizinol® (Botanical Melatonin Optimizer). Unlike synthetic melatonin, Maizinol® is a breakthrough botanical extract that works with your brain to optimize your own sleep signals. It is clinically proven to: IMPROVE DEEP SLEEP by increasing restorative REM cycles — LOWER NIGHTTIME CORTISOL to silence the stress signals that keep your mind racing — SYNC CIRCADIAN RHYTHM for a natural transition to sleep and a refreshed wake-up. Non-GMO, sustainably sourced, and non-habit forming.
