Ingredient transparency

The supplement industry has a transparency problem. Proprietary blends hide underdosed ingredients behind impressive-sounding labels. NeuroPouch publishes every ingredient, every function, and the research behind each one. If we can't explain it plainly, it doesn't go in the pouch.

Ingredient 01

Alpha-GPC

L-Alpha glycerylphosphorylcholine

Alpha-GPC is a choline compound that crosses the blood-brain barrier and increases acetylcholine levels in the brain. Acetylcholine is your brain's primary neurotransmitter for learning, memory formation, and motor control.

Unlike cheaper choline sources (choline bitartrate), Alpha-GPC has significantly higher bioavailability and direct CNS activity. It's used clinically in Europe for cognitive support and studied extensively for its role in memory, attention, and reaction time.

Research Evidence Level Strong

Working memory

Supports the ability to hold and manipulate information in the short term — critical for complex tasks, studying, and decision-making.

Reaction time

Increased acetylcholine levels are associated with faster neural transmission — measurable improvements in reaction speed under testing conditions.

Neuroprotection

Studied for protective effects against age-related cognitive decline. Used as a licensed pharmaceutical in Italy and other EU countries.

Published Research

Effect on memory and attention in Alzheimer's patients

A multi-centre trial found Alpha-GPC significantly improved cognitive function scores across attention, memory, and behavioural measures.

Cholinergic enhancement and cognitive speed

Review confirms Alpha-GPC as the most bioavailable oral choline source with direct CNS penetration, supporting attention and reaction time.

Parnetti et al. 2001 · Mech Ageing Dev

Why not just choline bitartrate?

Choline bitartrate is cheaper but has poor CNS penetration. Alpha-GPC is roughly 40% choline by weight with demonstrated blood-brain barrier crossing. It's what the research actually uses.

Ingredient 02

L-Theanine

Found naturally in green tea (Camellia sinensis)

L-Theanine is an amino acid that promotes alpha brainwave activity — the same relaxed-alert mental state associated with meditation, deep focus, and creative flow. It doesn't sedate you. It calms background noise so the signal gets through.

It's one of the most well-studied non-sedating anxiolytics available without a prescription. When paired with Alpha-GPC, the two compounds work synergistically — Alpha-GPC raises the ceiling of cognitive performance while L-Theanine smooths the ride.

Research Evidence Level Very Strong

Alpha wave induction

EEG studies confirm L-Theanine increases alpha brainwave frequency — associated with wakeful relaxation and sustained attention.

Anxiety reduction without sedation

Reduces physiological and psychological stress responses — cortisol, heart rate, perceived anxiety — without impairing alertness.

Synergy with stimulants

Most studied in combination with caffeine. NeuroPouch uses it independently to deliver the focus benefit without any stimulant dependency.

Published Research

Alpha wave generation and relaxed attention

EEG recordings showed significant increase in alpha activity within 40 minutes of L-Theanine ingestion, correlated with subjective reports of calm alertness.

Nobre et al. 2008 · Asia Pac J Clin Nutr

Stress reduction in high-demand cognitive tasks

Kimura et al. 2007 · Biol Psychol

Attention and cognitive performance

Randomised crossover trial showed L-Theanine improved speed and accuracy on an attention-switching task and reduced susceptibility to distracting information.

Foxe et al. 2012 · Nutr Neurosci

The "yin to caffeine's yang" without the caffeine

L-Theanine is famous as a caffeine modulator. But it works on its own — promoting focused calm through GABA activity and alpha waves independently of any stimulant co-administration.

Ingredient 03

Rhodiola Rosea

Adaptogenic root · Standardised to 3% rosavins, 1% salidroside

Rhodiola is an adaptogen — a compound that helps the body and mind resist and recover from physical and psychological stress. Unlike stimulants that force your system into a high state, adaptogens regulate. They raise performance when it's low and buffer the crash when it's high.

Rhodiola Rosea has one of the most robust bodies of evidence of any adaptogen, with multiple randomised controlled trials (RCTs) published in peer-reviewed journals. It is approved by the European Medicines Agency (EMA) as a traditional herbal medicine for reducing symptoms of stress and fatigue.

Research Evidence Level Strong (EMA-approved)
EMA-approved traditional herbal medicine

Mental fatigue reduction

Significantly reduces mental fatigue in conditions of stress-induced overload — documented in physicians, students, and military cadets under pressure.

Cortisol regulation

Salidroside and rosavins modulate the HPA axis, reducing cortisol secretion during acute stress events without suppressing baseline hormone function.

Sustained performance under pressure

Studies show maintained cognitive performance on complex tasks during periods of sleep deprivation and prolonged mental stress.

Published Research

Fatigue reduction in physicians during night shifts

Double-blind RCT: Rhodiola significantly improved cognitive performance and reduced fatigue in physicians working night shifts compared to placebo.

Darbinyan et al. 2000 · Phytomedicine

Anti-fatigue effect in students during exam stress

Spasov et al. 2000 · Phytomedicine

Repeated bout stress resilience in military cadets

Military cadets under intense stress showed significant improvements in capacity for mental work and reduction in fatigue with Rhodiola vs control.

Shevtsov et al. 2003 · Phytomedicine

Adaptogen ≠ stimulant

Adaptogens do not force your nervous system into a stimulated state. They are modulators — most effective at reducing the performance drop caused by stress, fatigue, and overload. This is why Rhodiola is safe for daily use without tolerance buildup.

Ingredient 04

Vitamin B12

Methylcobalamin form · Active and immediately bioavailable

B12 is essential to the functioning of the nervous system. It is required for the synthesis of myelin — the protective sheath around nerve fibres that determines how fast signals travel. Without adequate B12, neural transmission slows. Cognitive fatigue, poor concentration, and brain fog can all be symptoms of sub-optimal B12 status.

We use methylcobalamin — the active, co-enzyme form — rather than cyanocobalamin (the synthetic cheaper form). Methylcobalamin is directly usable by the body without further conversion and has better retention in tissue.

Research Evidence Level Established (EU Health Claims)
Authorised EU health claims (EFSA)

Nervous system function

EFSA-authorised claim: Vitamin B12 contributes to normal functioning of the nervous system.

Energy metabolism

EFSA-authorised claim: B12 contributes to normal energy-yielding metabolism — converting macronutrients to usable cellular energy.

Reduction of tiredness and fatigue

EFSA-authorised claim: B12 contributes to the reduction of tiredness and fatigue. Particularly relevant for vegetarians and vegans who are at higher risk of deficiency.

Why B12 Matters More Than You Think

Deficiency is surprisingly common

Studies suggest 6–20% of adults in developed countries have sub-optimal B12 levels. Vegans, vegetarians, and people over 50 are at highest risk due to dietary restriction or reduced absorption with age.

Cognitive symptoms of low B12

Memory problems, difficulty concentrating, persistent mental fatigue, and mood instability are all documented early symptoms of sub-clinical B12 deficiency — even before anaemia appears.

Buccal absorption advantage for B12

B12 absorption via oral tissue bypasses the need for intrinsic factor (produced in the stomach) — making buccal delivery particularly effective for those with digestive absorption issues.

Methylcobalamin vs Cyanocobalamin

Cyanocobalamin must be converted to methylcobalamin in the body before use. Methylcobalamin is the active form — ready to use immediately. Higher tissue retention. Zero conversion overhead. This is what we use.

Ingredient 05

Mint Extract

Peppermint (Mentha × piperita) · Standardised menthol content

Mint is not just flavour. It performs two distinct functions inside every NeuroPouch: sensory alerting and absorption enhancement. Both are evidence-based and both matter for how quickly and effectively the other ingredients work.

Menthol — the active compound in peppermint — activates TRPM8 receptors in the oral mucosa, triggering a cooling and refreshing sensation that acts as a mild alerting stimulus. Separately, menthol has been shown to increase mucosal permeability, which can accelerate the absorption of co-administered compounds through buccal tissue.

Research Evidence Level Moderate–Strong

Permeation enhancement

Menthol functions as a chemical permeation enhancer for buccal drug delivery — increasing mucosal permeability and improving transport of co-administered actives.

Cognitive alerting effect

Peppermint aroma and oral exposure have been associated with increased alertness, improved memory, and reduced mental fatigue in independent studies.

Trigeminal activation

The cooling sensation activates the trigeminal nerve — one of the largest cranial nerves — contributing to the immediate sense of mental clarity most users report within the first 2–3 minutes.

Published Research

Peppermint aroma and cognitive performance

Participants exposed to peppermint odour showed significantly better performance on memory, alertness, and overall cognitive quality compared to control and other odours.

Kennedy et al. 2016 · Nutrients

Mint is doing real work

Most oral products add mint purely for taste. In NeuroPouch, menthol serves a pharmacological function — making the other ingredients more bioavailable through the buccal route. It's chosen because it earns its place.

Delivery Method

Why buccal absorption changes everything.

Most supplements go in your mouth and then into your stomach, where they compete with food, get degraded by stomach acid, pass through the intestinal wall, and — critically — undergo first-pass metabolism in the liver before reaching your bloodstream. By then, a significant portion of the active compounds are gone.
