NTRPX Recover + Luna Sleep System

This document presents the complete scientific rationale and formulation strategy for the Recover (capsule) + Luna (drink) sleep system. The goal: help people fall asleep easier, prevent nighttime awakenings, maximize sleep quality, and wake refreshed — through multi-pathway synergistic mechanisms.

Executive Summary

The NTRPX sleep system addresses four distinct sleep challenges:

Challenge	Solution Pathway	Primary Compounds
1. Sleep Onset (falling asleep)	Thermoregulation + GABA enhancement + Circadian signaling	Glycine, L-Theanine, Melatonin
2. Sleep Maintenance (staying asleep)	Cortisol suppression + Anxiolysis + Sustained GABA	Ashwagandha, Magnolia Bark, Magnesium
3. Sleep Quality (deep + REM)	NMDA modulation + Brain magnesium + NAD+ preservation	Mg L-Threonate, Glycine, Apigenin
4. Morning Refreshment	Complete recovery + Circadian alignment	Tart Cherry, Glycine (next-day benefits)

System Architecture

I. Ingredient Deep Dive: Sleep Onset Pathway

A. Glycine (3,000 mg) — The Thermoregulatory Master Switch

Mechanism: Glycine is the only sleep compound that works primarily through core body temperature reduction — mimicking the natural thermal cascade that initiates sleep.

Mechanism of Action

Glycine acts on NMDA receptors in the suprachiasmatic nucleus (SCN) — the brain’s master circadian clock:

SCN NMDA Activation → Peripheral vasodilation signal
Vasodilation → Heat loss from extremities (hands/feet feel warm)
Core Temperature Drop → ~0.3°C reduction within 40 minutes
Sleep Signal → Natural sleep onset mechanism engaged

This is why people notice “warm hands and feet” after taking glycine — heat is being dissipated from the core.Critical Insight: SCN ablation in animal models completely abolishes glycine’s sleep-promoting effects, confirming this is the primary mechanism.

Clinical Evidence

Study	Design	Findings
Yamadera et al., 2007	RCT, n=11, polysomnography	3g glycine ↓ sleep latency, ↓ time to slow-wave sleep, ↑ sleep efficiency
Inagawa et al., 2006	RCT	3g glycine improved subjective sleep quality, ↓ daytime fatigue
Bannai et al., 2012	RCT, sleep-restricted adults	3g glycine improved next-day alertness, ↓ fatigue during sleep restriction
Kawai et al., 2015	Mechanistic (Nature)	Confirmed NMDA/SCN pathway; flumazenil did NOT block effects

Key Finding: Glycine improves next-day cognitive performance even during sleep restriction — suggesting it enhances sleep’s restorative value, not just duration.

Why 3g is the Magic Number

Doses below 1g show minimal effect
3g is the clinically validated threshold across all positive trials
Higher doses (5g+) show no additional benefit
3g produces measurable core temperature drop within 30-40 minutes
Safety: 30g/day showed no adverse effects in Phase 1 trials

Delivery: Luna drink (bulk powder — would require 5-6 capsules otherwise)

B. L-Theanine (200 mg) — Relaxation Without Sedation

Mechanism: L-Theanine promotes alpha brain wave activity (8-14 Hz) — the neural signature of wakeful relaxation and meditation.

Multi-Pathway Relaxation

L-Theanine acts through multiple neurotransmitter systems:

GABA Enhancement: Increases brain GABA levels
Glutamate Modulation: Partial antagonist at glutamate receptors (reduces excitatory tone)
Alpha Wave Induction: Directly promotes relaxed, alert brain state
Serotonin/Dopamine: Modest increases support mood and sleep readiness

Unique Property: Unlike sedatives, L-theanine promotes relaxation without cognitive impairment — you can still think clearly while feeling calm.

Synergy with GABA

A landmark 2019 study (Kim et al.) demonstrated that GABA + L-Theanine combined produced significantly greater sleep benefits than either alone:

Measure	GABA alone	L-Theanine alone	GABA + L-Theanine
Sleep Latency Reduction	20.7%	14.9%	Synergistic
Sleep Duration Increase	87.3%	26.8%	Synergistic
NREM Sleep	Modest ↑	Modest ↑	Significant ↑

Mechanism: L-Theanine stimulates endogenous GABA production while also crossing the blood-brain barrier rapidly, creating a dual-action calming effect.

Form: Suntheanine® (fermentation-derived, guaranteed L-isomer purity)
Delivery: Recover capsules

C. Melatonin (0.5 mg) — Circadian Signal, Not Sedative

Critical Misconception: Melatonin is not a sedative — it is a timing signal that tells the body “darkness has arrived; prepare for sleep.”

Why Low-Dose is Superior

MIT research (Zhdanova, Wurtman) demonstrated:

Dose	Plasma Level	Effect	Morning Grogginess
0.3 mg	Physiological	Full circadian benefit	None
3.0 mg	10-50× physiological	No additional benefit	Common
10 mg	100× physiological	Receptor desensitization risk	Very common

The 0.3-0.5 mg “physiological dose”:

Mimics natural nighttime melatonin levels
Provides full circadian entrainment benefit
No receptor desensitization
No morning grogginess
No tolerance development

Timing Matters More Than Dose

Recent meta-analysis (2024) found:

3 hours before desired bedtime = maximum efficacy
30 minutes before bed = suboptimal (commonly recommended but wrong)
The body needs time to respond to the signal

NTRPX Strategy: Recover capsules taken 60-90 minutes before bed, allowing melatonin to align with natural evening rise.

Delivery: Recover capsules (micro-dosed at 0.5 mg)

II. Ingredient Deep Dive: Sleep Maintenance Pathway

A. Ashwagandha KSM-66 (300 mg) — The Cortisol Buffer

Mechanism: Ashwagandha is an adaptogen that modulates the HPA axis, reducing cortisol — the “stress hormone” that causes middle-of-the-night awakenings.

Clinical Evidence for Sleep

Study	Population	Dose	Findings
Langade et al., 2019	Adults with insomnia, n=80	600 mg/day KSM-66	↑ sleep quality, ↓ sleep latency, ↑ mental alertness on waking
Salve et al., 2019	Healthy stressed adults, n=58	250-600 mg/day	↓ cortisol 19-27%, improved sleep quality
Kelgane et al., 2020	Elderly, n=50	600 mg/day	57% reduction in sleep quality complaints

2021 Meta-Analysis (5 RCTs, 400+ participants):

Small but significant effect on overall sleep
Dose-response: 600 mg > 300 mg > 250 mg
Duration-response: 8 weeks > 6 weeks
Population-specific: Greater effect in those with insomnia vs. healthy adults

Mechanism: HPA Axis Modulation

Stress → Hypothalamus → CRH → Pituitary → ACTH → Adrenal → CORTISOL
                                                        ↑
                                            Ashwagandha blocks here

Ashwagandha’s withanolides:

Reduce cortisol synthesis in adrenal glands
Modulate GABA-A receptors (anxiolytic)
Normalize elevated stress hormones
Support serotonin signaling

Clinical Outcome: 27% reduction in serum cortisol at 600 mg/day

Form: KSM-66® (root-only extract, >5% withanolides, “green chemistry” extraction)
Dose: 300 mg (clinically effective with other sleep compounds; 600 mg as monotherapy)
Delivery: Recover capsules

B. Magnolia Bark Extract (200 mg) — GABA-A Positive Allosteric Modulator

Mechanism: Honokiol and magnolol (active compounds in magnolia bark) bind to GABA-A receptors at the benzodiazepine site — producing anxiolytic and sleep-promoting effects without benzodiazepine side effects.

GABA-A Receptor Binding

Animal studies (Qu et al., 2012; Nature Neuropsychopharmacology) demonstrated:

Honokiol (10-20 mg/kg) shortened NREM sleep latency
Honokiol increased total NREM sleep time
Effects were blocked by flumazenil (benzo antagonist) — confirming GABA-A mechanism
No effect on REM sleep — preserves natural sleep architecture
Excited sleep-promoting neurons in ventrolateral preoptic area (VLPO)

Key Distinction from Benzodiazepines:

No motor impairment
No cognitive side effects
No physical dependence
No amnesia

Unique Subunit Selectivity

Honokiol shows preferential activity at:

α2 subunit → Anxiolytic effects (without sedation)
δ subunit → 900-1100% response vs. 300-500% at α/β/γ

This selectivity explains why magnolia bark produces relaxation and sleep promotion without excessive sedation or next-day grogginess.

Human Evidence

Relora® studies (magnolia + phellodendron):

Significant reduction in salivary cortisol
Improved anxiety scores (STAI)
Reduced stress-related eating
Postpartum women: improved sleep quality

Standalone magnolia bark (90% honokiol+magnolol):

200 mg dose commonly used in sleep formulas
Well-tolerated with no serious adverse events

Form: Magnolia officinalis bark extract standardized to 90% honokiol + magnolol
Dose: 200 mg
Delivery: Recover capsules

C. Magnesium L-Threonate (1,000 mg) — Brain-Penetrating Magnesium

Mechanism: Unlike other magnesium forms, Mg L-Threonate (Magtein®) crosses the blood-brain barrier to elevate brain magnesium levels, enhancing deep sleep and cognitive recovery.

Why Brain Magnesium Matters

Brain magnesium deficiency contributes to:

Reduced GABA-A receptor sensitivity
Increased glutamate excitotoxicity
Impaired synaptic plasticity
Poor sleep quality (especially N3 deep sleep)

Standard magnesium supplements (citrate, oxide, glycinate) raise serum magnesium but minimally affect brain levels. L-Threonate is unique in its CNS bioavailability.

Clinical Evidence

Study	Design	Key Findings
Hausenblas et al., 2024	RCT, n=80, Oura Ring + questionnaires	MgT improved ISI scores, deep/REM sleep, mood, alertness
Liu et al., 2016	RCT, n=44, cognitive impairment	MgT improved executive function, working memory
Magtein® 2025 study	RCT, n=60, young-middle aged	Improved cognitive performance, sleep quality, ↓ resting HR

Oura Ring Objective Data:

Increased time in deep sleep
Increased time in REM sleep
Improved heart rate variability (HRV) during sleep
Reduced resting heart rate (↑ parasympathetic activity)

Form: Magtein® (Magnesium L-Threonate)
Dose: 1,000 mg (providing ~75 mg elemental magnesium)
Delivery: Recover capsules (2 capsules typically needed)

III. Ingredient Deep Dive: Sleep Quality & Recovery Pathway

A. Apigenin (50 mg) — CD38 Inhibitor + Mild Anxiolytic

Dual Mechanism: Apigenin provides both immediate anxiolytic effects (GABA-A modulation) and longer-term NAD+ preservation (CD38 inhibition).

GABA-A Modulation

Apigenin binds to GABA-A receptors at a site distinct from benzodiazepines:

Produces mild sedation at higher doses
Anxiolytic without motor impairment
May enhance natural sleep pressure

Chamomile extract studies (containing ~1% apigenin):

540 mg chamomile showed trend toward improved daytime function in insomniacs
1500 mg/day reduced anxiety scores significantly

50 mg pure apigenin approximates the apigenin content of effective chamomile doses.

CD38 Inhibition & NAD+ Preservation

CD38 is a major NAD+-consuming enzyme that increases with age:

NAD+ pool → CD38 enzyme → cADPR (signaling) + NAD+ depletion
              ↑
         Apigenin blocks

By inhibiting CD38, apigenin:

Preserves NAD+ levels
Supports mitochondrial function during sleep
May enhance SIRT1 activity (longevity pathway)

Relevance to Sleep: NAD+ is critical for cellular repair processes that occur during deep sleep.

Form: Chamomile extract standardized to apigenin, or pure apigenin
Dose: 50 mg
Delivery: Recover capsules

B. Tart Cherry Extract (500 mg) — Natural Melatonin + Tryptophan + Anti-Inflammatory

Mechanism: Montmorency tart cherries contain natural melatonin, tryptophan, and proanthocyanidins that work synergistically for sleep.

Multi-Compound Sleep Support

Compound	Amount in 100g cherries	Function
Melatonin	2.1-13.5 ng/g	Circadian signaling
Tryptophan	9 mg	Serotonin/melatonin precursor
Proanthocyanidin B-2	Variable	Inhibits IDO (preserves tryptophan)
Anthocyanins	High	Anti-inflammatory

Key Insight: The melatonin dose from tart cherry is too low to explain sleep benefits alone (~0.14 μg vs. 300+ μg therapeutic dose). The mechanism involves:

IDO inhibition → Prevents tryptophan degradation → More available for serotonin/melatonin synthesis
Anti-inflammatory effects → Reduces sleep-disrupting cytokines (IL-6, TNF-α)
Natural melatonin → Gentle circadian support

Clinical Evidence

Study	Design	Findings
Howatson et al., 2012	RCT, n=20, 7 days	Tart cherry juice ↑ urinary melatonin, ↑ sleep time (+34 min), ↑ sleep efficiency
Losso et al., 2018	RCT, n=8, insomniacs >50yo	480mL/day × 2 weeks → +84 min sleep time, ↑ sleep efficiency
Pigeon et al., 2010	Pilot, n=15, chronic insomnia	Modest improvements in insomnia severity (WASO subscale)

2023 Meta-Analysis: Objective measures (actigraphy) showed significant increase in total sleep time with tart cherry.

Form: Montmorency Tart Cherry Extract (concentrated 10:1 or higher)
Dose: 500 mg (equivalent to ~5g fresh cherries, or ~100mL juice)
Delivery: Luna drink (pleasant flavor profile)

C. Taurine (1,000 mg) — GABAergic + Osmoregulatory

Mechanism: Taurine acts as a GABA-A receptor agonist and regulates cellular hydration — both supporting sleep.

GABAergic Activity

Taurine:

Binds to GABA-A receptors (weak agonist)
Binds to glycine receptors
Modulates calcium channels
Reduces neuronal excitability

This creates a gentle calming effect that complements other GABAergic compounds.

Osmoregulation & Cell Volume

During sleep, the brain undergoes significant glymphatic clearance — requiring proper fluid balance:

Taurine regulates cell volume (prevents swelling/shrinking)
Supports ion gradients across membranes
Enhances cellular detoxification

Form: Free-form Taurine
Dose: 1,000 mg
Delivery: Luna drink (highly soluble, slightly sweet taste)

D. L-Tryptophan (500 mg) + P5P (10 mg) — Serotonin/Melatonin Precursor Stack

Mechanism: L-Tryptophan is the essential amino acid precursor for serotonin and melatonin synthesis.

L-Tryptophan → 5-HTP (tryptophan hydroxylase) → Serotonin (AADC + P5P) → Melatonin

Why Tryptophan Over 5-HTP

Factor	L-Tryptophan	5-HTP
Safety	Excellent (decades of use)	Peripheral serotonin concerns
Regulation	Body controls conversion	Bypasses rate-limiting step
Dose flexibility	Wide therapeutic window	Narrower range
Side effects	Rare	GI upset, serotonin syndrome risk

NTRPX Choice: L-Tryptophan allows the body to regulate serotonin/melatonin synthesis naturally.

P5P Cofactor Requirement

Pyridoxal-5’-Phosphate (P5P) is the active form of vitamin B6 and is required for:

Aromatic amino acid decarboxylase (AADC) — converts 5-HTP → serotonin
Without adequate B6, tryptophan cannot be efficiently converted

10 mg P5P ensures the pathway is not rate-limited by cofactor availability.

Dose: 500 mg L-Tryptophan + 10 mg P5P
Delivery: Recover capsules

E. Zinc (15 mg) — Melatonin Synthesis Cofactor

Mechanism: Zinc is a cofactor for serotonin N-acetyltransferase (AANAT) — the rate-limiting enzyme in melatonin synthesis.

Zinc deficiency → Impaired melatonin production → Disrupted sleep
Zinc supplementation in deficient individuals improves sleep onset and quality
Also supports immune function during sleep’s recovery phase

Form: Zinc Picolinate (high bioavailability)
Dose: 15 mg (100% DV)
Delivery: Recover capsules

VI. Integration with NTRPX System

Circadian Closed-Loop Design

The Recover/Luna system completes the NTRPX circadian cycle:

Time	Product	Function	Prepares For
Morning	Boost	Cortisol alignment, dopamine, ATP	Cognitive peak
Afternoon	Sustain	Maintained energy, stress buffer	Evening wind-down
Evening	Recover + Luna	Parasympathetic shift, sleep onset	Deep restorative sleep
Night	Deep Sleep	Tissue repair, memory, hormones	Morning Boost readiness

Compound Flow Across System

Compound	Boost	Sustain	Recover	Luna	24h Logic
Magnesium	—	—	L-Threonate (brain)	Citrate (muscle)	Evening-only for sleep
B6 (P5P)	15 mg	—	10 mg	—	AM for energy, PM for serotonin
Zinc	15 mg	—	15 mg	—	Split AM/PM for absorption
L-Theanine	—	—	200 mg	200 mg	PM-only for relaxation
Glycine	—	—	—	3,000 mg	PM-only for thermoregulation
Ashwagandha	—	150 mg	300 mg	—	PM-dominant for cortisol

VII. Dosing Protocol

Standard Protocol

Time	Action	Products
6:00-8:00 AM	Wake	Boost capsules + Neuraldrink (AM)
12:00-2:00 PM	Midday	Sustain capsules
8:00-9:00 PM	Wind-down	Luna drink (60-90 min before bed)
9:00-10:00 PM	Pre-sleep	Recover capsules (30-60 min before bed)
10:00-11:00 PM	Lights out	—

Why Split Luna and Recover?

Luna (drink) first: Glycine needs 30-40 minutes to lower core temperature
Recover (capsules) second: Melatonin and anxiolytics work faster (15-30 min)
Staggered absorption: Prevents competition at absorption sites
Ritual value: Evening drink creates psychological wind-down signal

VIII. Expected Outcomes

Week 1-2: Adaptation Phase

Sleep onset: Noticeable improvement (glycine + L-theanine effect)
Subjective quality: Mild improvement
Daytime: Possible slight grogginess as body adjusts

Week 3-4: Optimization Phase

Sleep maintenance: Fewer awakenings (ashwagandha cortisol effect)
Deep sleep: Increased (Mg L-threonate accumulation)
Morning alertness: Significantly improved

Week 5+: Sustained Benefits

Circadian entrainment: More consistent sleep/wake times
Stress resilience: Better handling of daily stressors
Cognitive performance: Enhanced memory consolidation
Physical recovery: Improved tissue repair

Measurable Markers

For users with sleep trackers (Oura, Whoop, Apple Watch):

Metric	Expected Change	Mechanism
Sleep Latency	↓ 30-50%	Glycine, L-theanine, melatonin
Deep Sleep %	↑ 15-30%	Mg L-threonate, glycine

X. Compounds Considered But Excluded

The NTRPX Method requires every ingredient to pass three filters: mechanistic plausibility, clinical evidence, and practical parameters. Several popular sleep compounds were evaluated but did not make the final formulation.

Valerian Root — Excluded

Valerian Root Evaluation

Why it’s popular: Long traditional use (2,000+ years), “natural” sedative reputation, widely available, GABA-related mechanism claimed.NTRPX Evaluation:

Filter	Assessment	Details
Mechanistic	⚠️ Unclear	Multiple proposed mechanisms (GABA, adenosine, 5-HT). No consensus on primary MOA. Uncertain which compounds are active.
Clinical	❌ Inconsistent	Meta-analyses show mixed results. Cochrane 2020: “Evidence for valerian improving sleep quality is inconclusive.”
Practical	❌ Problematic	Intensely unpleasant odor; 2-4 week onset; next-day grogginess reports; standardization varies wildly.

Specific Issues:

Inconsistent clinical evidence: Unlike glycine (polysomnography-validated) or ashwagandha (meta-analysis positive), valerian trials are all over the map. Some positive, many negative, effect sizes small when present.
Mechanism not understood: We don’t actually know HOW valerian works. Proposed mechanisms include GABA receptor binding, adenosine modulation, and 5-HT effects—but none are conclusively demonstrated. This makes predicting synergies impossible.
Smell/taste disaster: Valerian has one of the most unpleasant odors in the botanical world (often described as “dirty socks” or “wet dog”). Would completely destroy Luna’s palatability and create compliance issues with capsules.
Delayed onset: Some studies suggest 2-4 weeks of daily use before effects emerge. Our formulation targets same-night efficacy with compounds like glycine and L-theanine that work acutely.
We have better GABA-ergics: Magnolia bark has cleaner evidence, known mechanism (GABA-A PAM at benzodiazepine site), no odor issues, and no delayed onset.

Verdict: Excluded. Does not meet NTRPX clinical evidence or practical standards. Magnolia bark provides superior GABA-ergic support with known mechanism.

Saffron (Crocus sativus) — Excluded from Sleep System

Saffron Evaluation for Sleep

Why it’s popular: Emerging research on mood and sleep, unique active compounds (crocin, safranal), “luxury” botanical appeal.NTRPX Evaluation for Recover/Luna:

Filter	Assessment	Details
Mechanistic	⚠️ Indirect	Primarily affects mood/depression via serotonin/dopamine. Sleep benefits appear secondary to mood improvement, not direct sleep promotion.
Clinical	⚠️ Limited sleep data	Strong depression trials (comparable to fluoxetine). Sleep studies exist but are secondary outcomes, not primary endpoints.
Practical	❌ Cost prohibitive	Most expensive spice in world (~$5,000-10,000/kg). Rampant adulteration. Would dramatically increase COGS.

Specific Issues:

Primarily a mood compound: The strongest saffron trials study depression and anxiety. Sleep benefits appear to be downstream of mood improvement rather than direct sleep-promoting mechanisms. We already have ashwagandha for this pathway.
Cost prohibitive: Quality saffron extract standardized to crocin/safranal is extremely expensive. Would increase product cost significantly without proportional benefit over existing ingredients.
Adulteration epidemic: The saffron supplement market is plagued with fraud. Many products contain safflower, turmeric, or synthetic dyes instead of actual saffron. Quality assurance is challenging.
Limited direct sleep data: Compared to glycine (multiple polysomnography RCTs showing direct sleep architecture effects) or melatonin (gold-standard circadian evidence), saffron’s sleep-specific evidence is thin.
Redundancy with ashwagandha: Both work partly through mood/anxiety pathways. Ashwagandha has stronger sleep-specific data, better cost profile, and established sourcing (KSM-66).

Verdict: Excluded from sleep formulation. Mood mechanism is indirect for sleep; ashwagandha provides superior anxiolytic support with better evidence and economics.

Saffron — NTRPX Evaluation for Boost/Sustain

Should Saffron Be in Boost or Sustain?

The Question: If saffron isn’t right for sleep, does it meet NTRPX standards for daytime mood/cognitive support in Boost or Sustain?Detailed Evaluation:

Mechanistic Filter ✅ PASS

Saffron’s active compounds have clear, well-documented mechanisms:

Compound	Mechanism	Relevance
Crocin	Serotonin reuptake inhibition, BDNF upregulation, anti-inflammatory	Mood, neuroprotection
Safranal	GABA-A modulation, antioxidant, dopaminergic effects	Anxiolysis, cognitive
Crocetin	Blood-brain barrier penetration, anti-inflammatory	CNS bioavailability

The mechanisms address identified pathways: mood regulation, stress resilience, and neuroprotection—all relevant to Boost (morning activation) and Sustain (afternoon maintenance).

Clinical Filter ✅ PASS (Strong)

This is where saffron shines:

Study	Design	Findings
Noorbala et al. 2005	RCT, n=40, vs. fluoxetine	Saffron 30mg = fluoxetine 20mg for depression (HAM-D)
Akhondzadeh et al. 2005	RCT, n=40, vs. imipramine	Saffron 30mg = imipramine 100mg for depression
Hausenblas et al. 2013	Meta-analysis, 5 RCTs	Large effect size (g=1.62) for mood improvement
Lopresti & Drummond 2014	Meta-analysis	Saffron significantly more effective than placebo for depression
Milajerdi et al. 2016	Systematic review	Consistent anxiolytic effects across studies

Key Finding: Multiple RCTs show saffron 30mg/day is comparable to pharmaceutical antidepressants for mild-moderate depression, with better tolerability.

Practical Filter ⚠️ CONDITIONAL PASS

Parameter	Assessment	Notes
Bioavailability	✅ Good	Crocin and crocetin cross BBB; safranal volatile but absorbed
Dose requirement	✅ Reasonable	30mg standardized extract (clinical dose) fits easily in capsules
Form selection	✅ Clear	Standardized to 3.5% crocin + 0.5% safranal (or equivalent)
Stability	⚠️ Moderate	Crocin light-sensitive; requires opaque packaging
Safety margin	✅ Wide	Well-tolerated up to 200mg/day in trials
Sourcing	⚠️ Challenging	Must use verified supplier with COA; high adulteration risk
Cost	⚠️ High	Significant COGS impact (~$50-100/kg for quality extract)

Synergy Analysis

Potential synergies with Boost ingredients:

+ Citicoline: Saffron’s BDNF effects + citicoline’s phospholipid support = enhanced neuroplasticity
+ Rhodiola (Sustain): Dual adaptogenic coverage for stress resilience
+ B-vitamins: Saffron may enhance methylation-dependent neurotransmitter synthesis

Potential redundancies:

Ashwagandha (Sustain): Both provide anxiolytic/mood benefits. However, mechanisms differ (ashwagandha = HPA axis; saffron = serotonergic), suggesting complementary rather than redundant effects.

NTRPX Verdict: TIER 2 (Supported) for Boost/Sustain

Recommendation: Saffron DOES meet NTRPX standards for inclusion in Boost or Sustain, with caveats:

Product	Fit	Rationale
Boost	⭐⭐⭐ Good	Morning mood support, cognitive enhancement, complements citicoline
Sustain	⭐⭐⭐⭐ Excellent	Afternoon stress buffering, sustained mood, pairs well with rhodiola

Implementation Requirements:

Sourcing: Partner with verified supplier (affron®, Saffr’Activ®, or equivalent) with COAs and adulteration testing
Standardization: Minimum 3.5% crocin (preferably lepticrosalides specification)
Dose: 30mg standardized extract (matches clinical trials)
Packaging: Opaque capsules/bottles to protect crocin from light degradation
Cost consideration: Premium positioning justified by clinical evidence

Suggested Addition:

SUSTAIN (updated)
├── Rhodiola (SHR-5) — 200mg — Adaptogen, fatigue resistance
├── Saffron (affron®) — 30mg — Mood support, anxiolysis  ← NEW
├── Ashwagandha (KSM-66) — 150mg — HPA axis, cortisol
└── [existing ingredients]

The combination of rhodiola (energy/fatigue), saffron (mood/anxiety), and ashwagandha (stress/cortisol) creates a comprehensive adaptogenic triad covering distinct but complementary pathways.

Tryptophan ↔ B6 + Zinc (biochemical pathway)
Ashwagandha ↔ Magnolia (dual cortisol/anxiety)
Apigenin ↔ Melatonin (different mechanisms, no overdose)

Practical Delivery

By splitting between capsules (Recover) and drink (Luna):

Capsule count stays manageable (5-6)
Bulky ingredients (glycine, taurine) delivered pleasantly
Creates evening ritual (psychological wind-down)
Allows optimal timing (drink first, capsules second)
