Key Benefits

What CognatiQ® Does For You

143% BDNF Elevation

Among the highest acute serum BDNF increases reported in published supplement research — measured at 143% above baseline in a controlled human trial, 4.6x greater than placebo.

Neuroplasticity On Demand

Activates the ERK/MAPK → CREB signaling cascade to drive BDNF gene expression — the brain’s primary growth signal for synaptic strengthening, memory formation, and learning capacity.

Polyphenol-Powered, Not Caffeine

The BDNF effect is driven by coffee fruit polyphenols (chlorogenic acids, procyanidins), not caffeine. CognatiQ® contains only ~2 mg of caffeine — adding neurotrophin support without stacking stimulant load.

Sharper Memory & Working Memory

Human trials in older adults with mild cognitive decline and in healthy young adults have shown improvements in working memory accuracy and response inhibition — the functional output of elevated BDNF signaling.

Cognitive Reserve & Mood Support

BDNF deficiency is strongly linked to depression and accelerated cognitive decline. By raising BDNF signaling through TrkB receptors, CognatiQ® may contribute to mood resilience and long-term cognitive reserve, though direct clinical benefits for mood have not been demonstrated.

The Problem

Your Brain’s Growth Signal Is Fading

Brain-Derived Neurotrophic Factor (BDNF) is often called “miracle-gro for the brain” — it governs neuronal survival, synaptic plasticity, and the formation of new memories. But modern life is systematically suppressing it.

BDNF Decline

BDNF levels fall with age, chronic stress, poor sleep, and sedentary behavior. Lower BDNF correlates with impaired memory, reduced cognitive flexibility, and increased risk of neurodegenerative conditions.

Impaired Neuroplasticity

Without adequate BDNF signaling through TrkB receptors, the brain’s ability to rewire in response to learning weakens. Long-term potentiation (LTP) — the cellular mechanism of memory — becomes less efficient.

Mood and Cognitive Reserve

BDNF deficiency is strongly linked to depression and anxiety. It also accelerates the loss of cognitive reserve — the buffer that protects against age-related decline and neurological injury.

Mechanism of Action

How CognatiQ® Works

CognatiQ® is a standardized whole-coffee-fruit extract — not coffee bean, not caffeine. It retains polyphenols (chlorogenic acids, procyanidins) from the fruit that are stripped out during standard coffee processing.

01

Polyphenol Absorption & BBB Penetration

Coffee fruit polyphenols are absorbed via the gastrointestinal tract and cross the blood-brain barrier. Unlike caffeine, these polyphenols do not act primarily as adenosine antagonists — they operate through a distinct neurotrophin pathway.

02

ERK/MAPK Pathway Activation

The polyphenols activate the ERK/MAPK (extracellular signal-regulated kinase / mitogen-activated protein kinase) signaling cascade — a primary upstream regulator of BDNF gene expression in neurons and glial cells.

03

CREB Phosphorylation

ERK activation leads to phosphorylation of CREB (cAMP response element-binding protein), a transcription factor that directly drives BDNF mRNA synthesis in the nucleus.

04

BDNF Synthesis & TrkB Signaling

Elevated BDNF protein is released into the synaptic cleft, binds TrkB receptors, and activates downstream signaling cascades that support synaptic strengthening, neuronal survival, and long-term potentiation.

Clinical Evidence

What the Research Shows

CognatiQ® is backed by two human clinical trials, including the landmark Reyes-Izquierdo study that established the 143% BDNF increase — among the highest reported for a single oral supplement.

Dosage & Bioavailability

Your Daily Dose in APEX

Clinical Dose
100 mg
Whole coffee fruit concentrate — the exact dose used in the pivotal Reyes-Izquierdo trial
APEX Delivers

Negligible caffeine — BDNF effect is polyphenol-driven, not caffeine-driven

Why this dose works: The Reyes-Izquierdo trial is one of the most frequently referenced studies in nootropic research for a single-ingredient BDNF effect. APEX delivers the exact 100 mg dose used in that trial — not a fraction of it. The BDNF increase was polyphenol-mediated; the negligible caffeine content (~2 mg) played no role in the effect.

Formula Synergy

How CognatiQ® Connects Across the System

CognatiQ® is the first pillar of the APEX BDNF amplification stack — working alongside two other ingredients to create a multi-pathway BDNF system no single compound can replicate.

APEX

Triple BDNF Amplification

CognatiQ® raises BDNF via the ERK/MAPK → CREB pathway. Magtein® elevates BDNF through NMDA receptor optimization and increased synaptic magnesium. Sabroxy® upregulates BDNF through PDE4 inhibition and cAMP elevation. Three separate biochemical routes, all converging on the same growth signal.

APEX

BDNF → Membrane Supply Chain

CognatiQ® drives BDNF synthesis and triggers the demand for new synaptic connections. Citicoline and Uridine supply the phosphatidylcholine building blocks (Kennedy pathway) to physically construct those new membranes. The signal and the substrate, co-delivered.

APEX → RESET

BDNF → Sleep Consolidation Cycle

CognatiQ® elevates BDNF during the day, promoting synaptic formation. RESET then provides Glycine for deep sleep architecture and AvailOm® DHA for overnight membrane repair and consolidation. The daytime growth signal requires nighttime repair to become permanent.

Summary

Key Takeaways

01

The Gold Standard for BDNF Induction

CognatiQ® at 100 mg produced one of the highest acute serum BDNF increases reported for any oral supplement — 143% above baseline, 4.6x greater than placebo. This is a measured biomarker outcome from a small controlled trial (n=25), not a mechanistic claim.

02

Full Clinical Dose Delivered

APEX delivers the exact 100 mg dose used in the Reyes-Izquierdo trial. Many products list CognatiQ® but use sub-clinical amounts. There is no ambiguity in APEX: you get what the research used.

03

Polyphenol Mechanism, Not Caffeine

The BDNF effect is driven by coffee fruit polyphenols via ERK/MAPK → CREB transcriptional activation — not caffeine. This means CognatiQ® adds neurotrophin support independently of the caffeine system, without stacking stimulant load.

04

Amplified by the Primacy Triple BDNF Stack

Inside APEX, CognatiQ® is one of three BDNF-elevating ingredients, each operating through a distinct mechanism. This multi-pathway architecture makes the combined BDNF signal more robust and less dependent on any single mechanism.

FAQ

Frequently Asked Questions

What is CognatiQ®?

CognatiQ® (formerly NeuroFactor®) is a patented, standardized extract of the whole coffee fruit — not the coffee bean. It retains the polyphenols (chlorogenic acids, procyanidins) from the fruit that are stripped out during standard coffee processing. These polyphenols are responsible for its BDNF-elevating effect, which is independent of caffeine.

What are the benefits of coffee fruit extract?

CognatiQ® is among the most studied coffee fruit extracts for cognitive performance. It raises BDNF (brain-derived neurotrophic factor) by 143% — the highest recorded increase for any single oral supplement. BDNF drives synaptic plasticity, memory formation, and neuronal survival. Human trials also show improvements in working memory accuracy and response inhibition.

Is CognatiQ® the same as caffeine?

No. CognatiQ® contains only ~2 mg of caffeine per 100 mg serving — negligible compared to a cup of coffee (~95 mg). Its cognitive effects are driven entirely by polyphenol activation of the ERK/MAPK → CREB pathway, which upregulates BDNF gene expression. This is a fundamentally different mechanism from caffeine’s adenosine receptor blockade.

What is BDNF and why does it matter?

BDNF (brain-derived neurotrophic factor) is the brain’s primary growth and repair signal. It governs synaptic plasticity, memory consolidation, neuronal survival, and the formation of new neural connections. BDNF levels decline with age, chronic stress, and sedentary behavior — and low BDNF is implicated in depression, cognitive decline, and neurodegenerative disease. CognatiQ® produced one of the largest acute serum BDNF increases reported for an oral supplement in a controlled trial.

How can I increase BDNF naturally?

Exercise (particularly high-intensity interval training) is the most well-established BDNF booster. Beyond exercise, CognatiQ® at 100 mg produces the largest acute BDNF increase documented for any supplement. APEX combines CognatiQ® with two additional BDNF-elevating ingredients (Magtein® and Sabroxy®), each working through a different pathway, creating a triple BDNF amplification system.

How much CognatiQ® is in APEX?

APEX delivers 100 mg of CognatiQ® per serving — the exact dose used in the pivotal Reyes-Izquierdo trial that demonstrated the 143% BDNF increase. Dose-response research confirmed that 100 mg captures approximately 90% of the maximum BDNF effect, with no meaningful benefit from higher doses.
