## Executive Summary & Unmet Pain Point
- **Summary**: Precision timing of Phosphatidylserine, Sensoril/KSM-66 Ashwagandha, L-Theanine, and Rhodiola Rosea based on diurnal Morning vs. Midnight Cortisol and DHEA-S ratios.
- **Unmet Pain Point**: Taking stimulating adaptogens like Rhodiola at night or sedating Ashwagandha at the wrong point in an inverted cortisol curve worsens morning exhaustion and 3 AM wired-but-tired insomnia.

## 2026 Quantitative Benchmark Matrix

| Parameter / Mechanism | Standard / Risk Baseline | NuraDose Optimization Protocol | Verified Outcome |
| :--- | :--- | :--- | :--- |
| Morning Cortisol Awakening Response | < 10 mcg/dL (Blunted Morning Drive) | 07:00 AM Rhodiola (3% Rosavins) + Morning Lux | Restores Peak Morning ATP Alertness |
| Nocturnal Cortisol Hyper-Arousal | 3:00 AM Hepatic Glycogen / Cortisol Spike | 20:30 PM Phosphatidylserine (400mg) + Mg Glycinate | -36% Nocturnal Cortisol Excursions |
| Cortisol-to-DHEA-S Catabolic Ratio | Elevated Catabolic Stress Index (>0.9) | Targeted Micronutrient + Vagal Tone Reset | Rebalances Anabolic Recovery Reserve |
