Evidence-Backed Delta Wave Rest.
A 60-day, randomized, double-blind, placebo-controlled study evaluating high-absorption chelated magnesium glycinate and Suntheanine® on stage-3 slow-wave sleep.
Delta Sleep Increase
Measured via continuous EEG polysomnography (p < 0.001).
Nocturnal Cortisol
Salivary biomarker collection measured at 11:00 PM and 3:00 AM.
Faster Sleep Latency
Accelerated sleep onset with zero heavy synthetic sedatives.
Zero Morning Fog
Subjective morning alertness rating using the Stanford Sleepiness Scale.
Why Form Matters: Chelated vs Other Compounds
| Compound | Cellular Absorption | GI Tolerance | Blood-Brain Penetration | Next-Day Fog |
|---|---|---|---|---|
| Lull Chelated Glycinate | 92.4% (Highest) | Gentle · No Laxative Effect | Rapid (Bound to Glycine) | 0% (Melatonin-Free) |
| Standard Magnesium Citrate | 38.0% | Causes loose digestion | Moderate | Low |
| Cheap Magnesium Oxide | 4.0% (Insoluble) | High digestive distress | Negligible | None |
| Synthetic Melatonin (5mg) | N/A (Hormone) | Neutral | Rapid Artificial Spike | High Grogginess (Hangover) |
Participant Protocol (n=148)
Subjects aged 24–65 presenting with non-clinical chronic nighttime sleep complaints. Baseline polysomnography established over 14 days prior to randomized double-blind administration of either Lull formula or identical excipient placebo nightly.
Safety & Non-Habituation
Upon cessation on Day 60, zero rebound insomnia or dependency symptoms were reported across all primary outcome metrics. Re-evaluated at Day 75 with sustained improvements in autonomic sleep regulation.
