01PAIRING
Caffeine + L-Theanine
Alertness, considered.
Caffeine meets L-theanine. A familiar alertness ingredient and a tea amino acid, paired because human studies have explored their combined effects on attention.
- Caffeine anhydrous
- The alertness component. Caffeine blocks adenosine receptors involved in sleep and wakefulness.
- L-Theanine
- The tea amino acid. Its combination with caffeine has been studied directly in human attention tasks.
The pairing logic
- Adenosine
- L-Theanine
- Attention
Why this pairingHuman attention studies · ingredient evidence
The mechanism
Caffeine acts at adenosine A1 and A2A receptors. L-theanine brings a different neurochemical profile: laboratory work has investigated its interaction with glutamate-receptor sites, while its precise contribution in people is an open research question. We pair them because human attention studies have investigated the combination directly. Two distinct ingredients, with a deliberate research rationale.
The pairing logic
Adenosine
Caffeine blocks receptors
L-Theanine
A different neurochemical profile
Attention
Specific tasks studied in people
What the evidence says
A 27-person trial reported better attention switching and less distraction with the combination versus placebo. Another found a positive interaction on delayed word-recognition reaction time. These task-specific findings are why this pairing anchors Flow's research story. Results vary with task, dose and population; a 2026 athlete trial found no added visuomotor benefit.
Published ingredient studies inform Flow's design. The finished formula requires its own efficacy and safety validation.

02PAIRING
Alpha-GPC + Huperzine A
The architecture of a signal.
Two roles in acetylcholine biology, paired with purpose. Alpha-GPC supplies choline; huperzine A is studied for inhibiting the enzyme that breaks acetylcholine down.
- Alpha-GPC
- The choline source. Choline is a building material for acetylcholine, a neurotransmitter involved in attention and memory.
- Huperzine A
- The enzyme inhibitor. Huperzine A inhibits acetylcholinesterase, the enzyme that breaks acetylcholine down.
The pairing logic
- Choline
- Acetylcholine
- Breakdown
Why this pairingComplementary roles · mechanistic rationale
The mechanism
Neurons use choline to synthesize acetylcholine, a neurotransmitter involved in attention and memory. Acetylcholinesterase helps end that signal by breaking it down. Alpha-GPC supplies choline; huperzine A inhibits the breakdown enzyme. Bringing these complementary roles together is the biochemical rationale behind the pairing.
The pairing logic
Choline
Alpha-GPC provides a source
Acetylcholine
A neurotransmitter made from choline
Breakdown
Huperzine A inhibits the enzyme
What the evidence says
Alpha-GPC research has reported improvements on selected Stroop measures. That study did not show significant N-back improvements, and a 15-person huperzine A trial found no cognitive difference during exercise. The pairing's foundation is acetylcholine biology; its combined effect in healthy adults is a question for direct study.

03PAIRING
L-Dopa + EGCG
Botanical origins. Deliberate design.
Mucuna's dopamine precursor meets a green-tea catechin studied in its metabolism. A deliberate pairing built around a research question: how these ingredients interact along the L-DOPA pathway.
- Mucuna pruriens extract
- The botanical precursor. Mucuna supplies L-DOPA, a building block the body can convert into dopamine.
- Green tea extract
- The research counterpart. Green tea supplies EGCG, a catechin studied for its interaction with COMT in L-DOPA metabolism.
The pairing logic
- L-DOPA
- COMT
- EGCG
Why this pairingEmerging research · preclinical rationale
The mechanism
AADC can convert L-DOPA into dopamine. COMT takes L-DOPA down a different metabolic route, forming 3-O-methyldopa. EGCG has been investigated for inhibiting that COMT route. The pairing idea is purposeful: bring together a dopamine precursor and a tea catechin studied for how that precursor is metabolized.
The pairing logic
L-DOPA
A dopamine precursor
COMT
A route in L-DOPA metabolism
EGCG
A catechin studied at that route
What the evidence says
Laboratory work found that EGCG inhibited L-DOPA methylation; a rat study using L-DOPA plus carbidopa also found reduced methylation. These findings give the pairing a concrete research rationale. Human translation is the next question: a 24-person EGCG-only study found increased red-cell COMT activity rather than inhibition and did not test this pairing or cognition. Human focus and tolerability benefits still need direct study.

THE EVIDENCE BEHIND THE DESIGN
Our research standard.
Each pairing has a stated rationale, a visible evidence level and links to its sources. Published ingredient studies inform the design; they do not establish Flow's efficacy or safety. The finished formula requires its own validation.
Mechanistic rationale
Alpha-GPC and huperzine A have complementary roles in acetylcholine biology. Their combined effect in healthy adults requires direct study.
Explore the biochemical rationalePreclinical rationale
L-DOPA with EGCG draws on laboratory and animal research into metabolism. Human findings leave the proposed interaction an open question.

QUESTIONS & ANSWERS
A few things to know.
The product, the research and what comes next.
What is FORTIS Flow?
Flow is FORTIS Form LLC's first powder drink mix in development, designed around three ingredient pairings and a single-serve stick format.
Who is Flow designed for?
Adults navigating demanding work and study: professionals, founders and university students. Its single-serve stick format is being developed around a simple ritual for those routines.
Why design Flow around these pairings?
Every ingredient has a defined role. Caffeine with L-theanine draws on human attention research. Alpha-GPC with huperzine A explores complementary roles in acetylcholine biology. Mucuna with EGCG draws on research into dopamine-precursor metabolism. The design brings these three rationales into one format.
How strong is the science?
Each chapter shows its evidence level and links to the original research. Caffeine with L-theanine has direct human attention studies; the other pairings draw on mechanistic or preclinical work. Ingredient research guides the design. Flow-specific efficacy and safety require separate validation.
Are these the final product details?
This is your first look at Flow's formulation and packaging direction. Final specifications, serving information and packaging will be published as they are confirmed. The stick artwork is a packaging concept.
When will Flow be available?
Launch timing, pricing and availability will be announced here at fortisform.com when confirmed. Until then, explore the three pairings and the thinking behind Flow.
