The Ultimate Sleep Stack (without Melatonin)
Melatonin is one of the most popular sleep aids on the market—but it’s not always the best option. Many users report grogginess, diminished effect over time, and hormonal interference, especially with prolonged use.
At Green Star Labs, we’ve developed a melatonin-free sleep stack using clinically supported, synergistic compounds that target calmness, neurotransmitter balance, and deep-wave sleep—without next-day drowsiness.
Why Skip Melatonin?
It’s a hormone—long-term use can affect your natural circadian rhythm.
Diminishing returns: Tolerance can build quickly.
Can cause vivid dreams, irritability, and even anxiety in sensitive individuals.
The Ultimate Melatonin-Free Sleep Stack
Each ingredient below has been carefully chosen to support different stages of sleep physiology—from calming the mind to improving sleep architecture and cellular recovery.
Ingredient
Magnesium Glycinate
L-Theanine
Apigenin
Glycine
L-Tryptophan
Holy Basil Extract
Zinc (as Zinc Picolinate)
Dose (per serving)
200–300 mg
200 mg
50 mg
500 mg
250–500 mg
250 mg
10–15 mg
Function
Calms the nervous system; supports GABA receptors
Promotes relaxation and alpha brain waves
Natural flavonoid; anxiolytic, enhances GABA activity
Lowers body temp, improves sleep depth
Precursor to serotonin → helps initiate sleep
Adaptogen that reduces cortisol and mental tension
Cofactor for serotonin/melatonin production and immune support
Optional synergizers:
Reishi Mushroom Extract (300 mg): Deepens REM cycles
GABA (100–200 mg): Directly induces calmness in some individuals
How These Compounds Work Together
- Magnesium + Apigenin + L-Theanine = Reduces neural excitability and calms racing thoughts.
- Tryptophan + Zinc = Supports natural serotonin and melatonin production—without delivering a direct hormonal dose.
- Glycine + Holy Basil = Enhances sleep depth while lowering internal stress load.
- All ingredients are non-habit forming, and most are adaptogenic or neuromodulatory, making them safe for daily use.
Capsule or Gummy Formats Available
Green Star Labs can formulate this stack into:
- 2-capsule systems (AM/PM adaptogen and PM calm formula)
- Sugar-free gummies
- Nightly powder blends with calming flavors like lavender-vanilla or berry chamomile
