Affron®
The only patented saffron extract with a standardized Lepticrosalides® content — supported by clinical research across 6 RCTs for mood support, sleep improvement, and melatonin preservation through multi-pathway monoamine modulation and HPA axis regulation.
Primacy Research
What Affron® Does For You
Mood Support Studied in Multiple RCTs
A meta-analysis of 5 RCTs found a large effect size (Hedges’ g=1.62) for saffron vs. placebo in supporting healthy mood. Additional academic research has further examined saffron’s mood-supporting properties.
Sleep Quality Improvement
A dedicated RCT demonstrated significant improvements in insomnia severity and restorative sleep quality scores in adults with self-reported poor sleep after 28 days of supplementation.
Multi-Pathway Monoamine Modulation
Supports serotonin, dopamine, and norepinephrine availability through reuptake modulation — a broad monoamine support profile supporting mood, motivation, and reward processing.
HPA Axis & Cortisol Regulation
Modulates the hypothalamic-pituitary-adrenal axis to reduce evening cortisol burden, preserving tryptophan availability for serotonin and melatonin synthesis during the critical pre-sleep window.
BDNF & Neuroplasticity Support
Crocin and safranal increase hippocampal BDNF expression, supporting overnight neurogenesis and synaptic plasticity that complement APEX’s daytime BDNF amplification stack.
The Mood-Sleep Disruption Cycle
Mood and sleep are governed by the same neurotransmitter systems — serotonin, melatonin, and cortisol — and they fail together. Evening cortisol elevation impairs serotonin synthesis, reduced serotonin limits melatonin production, poor sleep amplifies the next day’s stress response, and the cycle repeats. RESET’s Affron® targets this cycle at its root: the serotonergic and HPA axis mechanisms that drive both mood and sleep quality.
Serotonin Under Siege
Evening cortisol elevation directly suppresses tryptophan availability for serotonin synthesis by diverting tryptophan toward the kynurenine pathway. The result: reduced serotonin in the raphe nuclei — the primary brain region governing mood, emotional regulation, and sleep initiation. Chronic stress-induced serotonin suppression is the neurochemical substrate of stress-related mood dysregulation.
Melatonin Starvation
Melatonin is synthesized from serotonin via N-acetyltransferase and HIOMT in the pineal gland. Serotonin depletion from stress-induced kynurenine diversion directly limits melatonin synthesis capacity — producing the paradox of stress-induced insomnia: the person is exhausted but cannot initiate or maintain sleep because the serotonin → melatonin conversion chain is substrate-limited.
Rumination Locks the Loop
Elevated evening cortisol activates the amygdala and suppresses prefrontal cortex inhibitory control, creating the ruminative thought patterns that prevent sleep onset. This is not a sleep architecture problem alone — it is a prefrontal-amygdala imbalance driven by cortisol that perpetuates the mood-sleep disruption cycle. Breaking the cycle requires targeting cortisol, not just sleep latency.
How Affron® Works
Affron® is standardized to ≥3.5% Lepticrosalides® — a proprietary marker representing the active apocarotenoid fraction of saffron (Crocus sativus L.) stigmas, primarily safranal and crocins. These compounds act through multiple convergent mechanisms to modulate serotonin, dopamine, melatonin, BDNF, and the HPA axis simultaneously.
Serotonin Reuptake Inhibition
Safranal and crocins inhibit the serotonin transporter (SERT), slowing the reuptake of serotonin from the synapse back into the presynaptic neuron. This mechanism supports serotonin availability through reuptake modulation, with a broader receptor engagement profile than single-target approaches. The result is increased serotonergic tone in the raphe-limbic projection pathways that regulate mood and sleep initiation.
Broad Monoamine Reuptake Inhibition
Affron®’s active compounds also inhibit dopamine (DAT) and norepinephrine (NET) reuptake transporters, providing broader monoaminergic tone enhancement. This broad monoamine support profile provides dopaminergic support for motivation and reward processing alongside serotonergic mood stabilization.
BDNF Upregulation
Crocin and safranal increase hippocampal BDNF expression, consistent with the hypothesis that the mood-supporting effect of serotonergic agents is at least partly mediated by BDNF-dependent neurogenesis and synaptic plasticity. RESET’s BDNF upregulation via Affron® provides overnight hippocampal support that complements APEX’s daytime BDNF amplification stack.
NF-κB Inhibition: Neuroinflammation Reduction
Crocins inhibit NF-κB activation, reducing the production of pro-inflammatory cytokines that contribute to neuroinflammation-associated mood dysregulation. Research suggests that elevated IL-6, TNF-α, and IL-1β can impair monoamine synthesis and receptor sensitivity — Affron®’s NF-κB inhibition addresses this pathway.
HPA Axis Regulation
Safranal modulates the hypothalamic-pituitary-adrenal axis, reducing cortisol response to perceived stress and accelerating cortisol clearance in the evening. This HPA modulation works in the same direction as SalidroPURE™ in APEX but through different upstream signaling, providing complementary cortisol management that spans the full 24-hour cycle.
Sigma-1 Receptor Activity
Crocins are sigma-1 receptor agonists. Sigma-1 receptors are endoplasmic reticulum chaperones that regulate neurosteroid synthesis, glutamate signaling, and neuroprotective responses. Sigma-1 agonism contributes to the anxiolytic and mood-supporting effects of saffron and provides a mechanistic explanation for Affron®’s sleep-onset improvement independent of its serotonergic actions.

Your Daily Dose in RESET
Why this dose works: RESET delivers the exact 28 mg dose of Affron® used in every published clinical trial — including the 5-RCT meta-analysis showing a 1.62 Hedges’ g effect size and the dedicated sleep RCT showing 44% PSQI improvement. Affron®’s Lepticrosalides® standardization ensures consistent active compound content across batches, addressing the batch-to-batch variability that undermines non-standardized saffron extracts.
How Affron® Connects Across the System
Affron®’s serotonergic, melatoninergic, and HPA axis mechanisms place it at the center of RESET’s mood-sleep architecture. Its pathways connect to glycine, magnesium bisglycinate, and APEX’s adaptogenic system in a 24-hour neurotransmitter management loop.
Serotonin → Melatonin Conversion Chain
Affron® increases serotonergic tone through serotonin reuptake modulation. Elevated serotonin availability in the pineal gland provides more substrate for N-acetyltransferase — the rate-limiting enzyme of melatonin synthesis. RESET’s magnesium bisglycinate (Albion®) supports GABA receptor function, which works synergistically with melatonin for sleep initiation. Affron® feeds the serotonin-melatonin pipeline; magnesium supports the sleep architecture that melatonin initiates.
Dual Melatonin Strategy
RESET increases melatonin through two complementary mechanisms: Affron® enhances endogenous melatonin synthesis by increasing serotonin substrate availability (upstream), while RESET may include additional sleep support compounds that act downstream on melatonin receptor sensitivity. This dual approach addresses both the production bottleneck (serotonin supply) and the signaling efficiency of the melatonin pathway.
Serotonergic + GABAergic Convergence
RESET’s glycine (6,000 mg) acts as an inhibitory neurotransmitter at glycine receptors in the spinal cord and brainstem, contributing to motor quiescence during sleep. Magnesium bisglycinate supports GABA-A receptor function. Affron®’s serotonergic and sigma-1 receptor activity mechanisms add a third inhibitory/anxiolytic pathway. These three mechanisms converge on reducing central nervous system arousal for sleep initiation.
Cortisol Clearing → Serotonin Preservation
Evening cortisol elevation diverts tryptophan toward the kynurenine pathway, reducing serotonin synthesis capacity. Affron®’s HPA axis modulation reduces evening cortisol, which in turn reduces kynurenine pathway activation and preserves tryptophan availability for serotonin synthesis. The cortisol-reducing and serotonin-protecting mechanisms of Affron® are therefore self-reinforcing.
Circadian Neurotransmitter Handoff
APEX’s SalidroPURE™ manages daytime catecholamine availability through MAO inhibition, preserving dopamine and norepinephrine for focus and motivation. RESET’s Affron® manages evening serotonin availability through serotonin reuptake modulation, providing the substrate for melatonin synthesis and mood stabilization overnight. The daytime catecholamine system (APEX) hands off to the nighttime serotonergic system (RESET) — completing the 24-hour neurotransmitter management cycle.
24-Hour Adaptogenic Mood Continuity
SalidroPURE™ (APEX) modulates HPA axis sensitivity to daytime stressors. Affron® (RESET) modulates HPA axis clearance overnight, reducing the residual cortisol burden that would otherwise persist into sleep. Together, they provide HPA axis support across the full circadian cycle: adaptive calibration during the day, accelerated clearance at night. Neither ingredient alone achieves 24-hour HPA management.
Key Takeaways
The Only Saffron Extract with a 6-Trial Evidence Base
Affron® is backed by 6 clinical trials including a 5-RCT meta-analysis (Hedges’ g=1.62) and a dedicated sleep RCT (44% PSQI improvement). This depth of evidence at a single specific dose (28 mg) is unmatched by any other standardized saffron extract.
Targets the Mood-Sleep Connection at Its Root
Affron® doesn’t just improve sleep or mood in isolation — it addresses the cortisol-serotonin-melatonin cascade that governs both simultaneously. By reducing evening cortisol (HPA modulation), preserving tryptophan for serotonin synthesis, and supporting serotonin reuptake modulation, it addresses the upstream neurochemical factors that drive both mood dysregulation and sleep disruption.
Multi-Mechanism Mood & Sleep Support
Affron®’s active compounds engage serotonin reuptake modulation, dopamine availability support, norepinephrine availability support, sigma-1 receptor activity, BDNF, NF-κB, and the HPA axis simultaneously. This multi-mechanism profile provides broader mood and sleep support than single-mechanism approaches.
The Serotonin Hub of RESET’s 24-Hour System
Inside RESET, Affron® connects the cortisol clearance system (HPA modulation), the melatonin synthesis pathway (serotonin substrate supply), the GABAergic sleep system (sigma-1/anxiolytic), and the APEX daytime catecholamine system (circadian handoff). It is not a standalone mood supplement but the neurotransmitter hub that links RESET’s sleep and recovery architecture to APEX’s daytime cognitive stack.
