ICON Focus Gum: Liquid-Core enfinity Paraxanthine in a Chewable Supplement

When TSI Group's enfinity® paraxanthine started showing up in energy drinks, pre-workouts, and even nicotine-free focus pouches, it was clear the ingredient had legs beyond the standard capsule format. And now it's landed in gum! Specifically, inside a novel new gum's liquid core:

Paraxanthine has gone from capsules to drinks to pouches, and now it's in chewing gum. ICON Focus Gum delivers 100mg enfinity® paraxanthine and 100mg Alpha-GPC through a Liquid Core chew. Buccal absorption means it hits fast.

ICON™ Focus Gum is a nootropic chewing gum from Icon Formulation that pairs 100mg of enfinity® paraxanthine with 100mg of Alpha-GPC per piece, delivered through what the brand calls its Liquid Core® Technology. The idea is straightforward: bite down, the liquid center bursts, and both actives hit your buccal tissue immediately rather than waiting for a capsule to dissolve in your stomach.

Why Paraxanthine in Gum?

If you've read our deep dive on paraxanthine, you know it's the primary metabolite that caffeine converts to in the body, and it's the compound responsible for a significant portion of caffeine's focus and energy effects. Taken directly, it skips the jitters, vasoconstriction, and anxiety that caffeine brings along -- particularly for slow caffeine metabolizers. The 100mg dose here aligns with the enfinity® sweet spot used across most nootropic products.

Gum is an interesting delivery vehicle for a stimulant ingredient. Buccal absorption (through the cheek and gum tissue) can be meaningfully faster than GI-tract absorption, which makes this format a genuinely reasonable choice for an ingredient you want to feel quickly. The Arctic Mint flavor is the current offering.

ICON Focus Gum Ingredients

Each 1-piece serving provides the following:

• Paraxanthine (as enfinity®) - 100mg

  Paraxanthine (as enfinity®) is caffeine's primary metabolite, and it's the compound your liver converts roughly 80% of ingested caffeine into before it delivers most of caffeine's familiar energy and focus effects.^[1] ICON delivers it directly at 100mg per piece, skipping the conversion step entirely and leaving behind the parts of caffeine responsible for jitters and anxiety.

  How It Works

  Paraxanthine shares caffeine's core mechanism: blocking adenosine A1 and A2A receptors to promote wakefulness and support cognitive function.^[2] But it adds a second pathway caffeine doesn't have access to. Paraxanthine inhibits cGMP-preferring phosphodiesterases (PDEs), which activates nitric oxide neurotransmission in the striatum and drives a measurable increase in dopamine release -- an effect researchers have documented with paraxanthine but not caffeine!^[3][2] That dual-pathway profile is part of why its cognitive effects tend to feel distinct from straight caffeine.

  What the Research Shows

  Clinical data support cognitive benefits at the 100mg dose found in each piece. A dose-response trial found that both 100mg and 200mg produced meaningful improvements in short-term memory, sustained attention, executive function, and reaction time, with the two higher doses showing more consistent results than 50mg.^[4] A separate 200mg trial demonstrated lasting gains in memory storage and vigilance across six hours, with response times continuing to improve through the experiment while placebo group times declined.^[5] Chewing two pieces puts you squarely in that 200mg range the research used most extensively.

  

  Paraxanthine is the primary metabolite of caffeine, providing most of caffeine's beneficial effects. Now you can take it directly with enfinity!

  Preclinical data add another layer: paraxanthine elevated brain-derived neurotrophic factor (BDNF) to a greater extent than caffeine alongside acetylcholine and dopamine in rat models, pointing toward a neuroplasticity angle that warrants follow-up in human trials.^[6] Our coverage of this study is at New Preclinical Study Shows Paraxanthine Enhances Memory and Brain Function Better Than Caffeine.

  The Caffeine-Free Advantage

  Not everyone processes caffeine the same way. Carriers of the slow-metabolizer CYP1A2 genotype can see performance actually decline at higher caffeine doses rather than improve.^[7] Paraxanthine bypasses that variable entirely since it's already downstream of the CYP1A2 enzyme, and research has shown it produces less anxiety than caffeine at comparable stimulatory doses.^[8] Our article on fast and slow caffeine metabolizers covers why that genetic split matters for a large share of the population.

  Additionally, a comprehensive toxicology assessment of enfinity® paraxanthine led by Dr. Martin Purpura found no evidence of mutagenicity or genotoxicity, and a 90-day repeated-dose study established a no observed adverse effect level (NOAEL) at or above 300mg/kg body weight per day in rats.^[9]

  Synergy with Alpha-GPC

  Paired with Alpha-GPC's acetylcholine support, paraxanthine's dopamine and nitric oxide activity covers distinct neurochemical territory. The two ingredients target different neurotransmitter systems (one cholinergic, one dopaminergic/nitrergic), which makes this a mechanistically sound stack for cognitive output rather than two ingredients stepping on each other's toes.

  

  Planning to quit caffeine? Wait. ~50% of people are slow caffeine metabolizers who get jitters, insomnia, and anxiety. The fix isn't quitting stimulants--it's switching to paraxanthine (enfinity), caffeine's primary metabolite without the genetic lottery.

• Alpha-GPC (L-Alpha Glycerylphosphorylcholine) - 100mg

  Alpha-GPC (L-alpha glycerylphosphorylcholine) is a bioavailable choline precursor that crosses the blood-brain barrier and raises acetylcholine levels in hippocampal and cortical tissue.^[10] Acetylcholine drives attention, learning, and working memory, making choline availability a direct input into cognitive output.

  After ingestion, alpha-GPC is cleaved to release free choline, which neurons incorporate into acetylcholine via choline acetyltransferase. Animal research shows it dose-dependently increases hippocampal ACh release and reverses cholinergic amnesia.^[11] In a randomized, double-blind crossover trial with healthy men, both a 315mg and a 630mg dose improved Stroop test scores versus placebo, with the higher dose also producing significantly faster completion times.^[12] Those trial doses exceed what a single piece delivers, so chewing two moves you to 200mg and closer to the studied range.

  Alongside paraxanthine's dopaminergic and nitrergic activity, alpha-GPC covers the cholinergic side of the cognitive stack. The two ingredients target distinct neurotransmitter systems, making the pairing mechanistically coherent rather than redundant. One human study also found alpha-GPC supported motivation scores versus placebo, adding a motivational dimension to its focus-forward profile.^[13]

How to Use

• When to take it: Chew one piece anytime you need focus on demand... but avoid within a few hours of bedtime. Note that paraxanthine's half-life is a bit shorter than caffeine, so you can time it slightly closer to bed, but be reasonable.
• With or without food: Either works... no food requirement.
• Other notes: Start with one piece to gauge your tolerance. You can chew up to two pieces per serving but don't exceed four pieces within a 24-hour period. enfinity is generally dosed at a maximum of 300mg at once, and 400mg total per day, so take that into account.

Stacks Well With

• Pre-workout: ICON chews well during warm-up for a light cognitive edge on top of your pre-workout, though check whether your pre already has paraxanthine or caffeine to avoid doubling up on stimulants.
• Stimulant-free nootropics or adaptogens: Stacks cleanly with anything stim-free since paraxanthine covers the energy side.

Who It's For

• Athletes and gym-goers: A convenient on-the-go focus boost that doesn't require carrying a shaker or can.
• Students and professionals: The portable format and clean paraxanthine profile make it easy to use in environments where energy drinks aren't practical.
• Caffeine-sensitive adults: Anyone who wants cognitive lift without caffeine's cardiovascular and anxiety side effects.
• Travelers: How much better is this than spending a day's salary on airport coffee? ICON is quick, easy, TSA-friendly, and will keep your breath fresh for your fellow travelers.

Conclusion: Liquid Tech Meets Clean Cognition

ICON Focus Gum is a format-forward product built around two well-studied nootropic ingredients, and the liquid core delivery angle isn't just a gimmick -- gum's buccal absorption is a legitimate reason to pay attention to this format. enfinity® paraxanthine at 100mg and alpha-GPC at 100mg is a focused, no-fluff stack, and the portable, discreet form factor makes it genuinely practical in ways that a can or shaker bottle can't match.

What's worth watching is whether gum as a delivery format earns consumer adoption the way pouches have. We covered how Ultra Focus Pouches ignited real momentum for enfinity® in an unexpected format -- gum could do the same for a different use case. The sugar-free xylitol base adds a minor dental health angle that energy drinks can't match either.
