Overview This is a practical guide to managing jet lag through smarter caffeine use. In this guide, you'll find what caffeine does to a sleep-disrupted circadian clock, why eastbound travel hits harder than westbound, and why airport coffee is a less effective strategy than it might seem. It outlines the science on dose and timing, clarifies why the L-theanine pairing matters, and lays out a practical caffeine playbook for the most common flight scenarios. Intro Nobody searches 'what is jet lag' while they’re on the plane. They search it at 2pm local time, the third day in, when the brain fog still hasn't lifted and they've already had four coffees. Circadian biology is well documented— you can find the science anywhere. What it won’t prepare you for is landing at the terminal at 6 a.m. with a client meeting at 9. That's the gap this piece of writing fills. It doesn't attempt to explain what jet lag is. Instead, it focuses on the practical side: what caffeine actually does to a sleep-disrupted body clock, why dose and timing matter more than most travellers realize, and why the format you choose for that caffeine is a more significant question than it might seem. The Traveler's Real Enemy Isn't the Flight. It's What Comes After. The flight gets the blame because it's the uncomfortable part. But jet lag symptoms - disorientation, mood instability, slower reaction time, difficulty concentrating - don't peak on the plane. They peak after you land, when the adrenaline of travel wears off and your internal clock realizes it's been relocated without consent. According to the Cleveland Clinic, symptoms can persist for several days depending on how many time zones you've crossed.* For a consultant with back-to-back meetings starting the morning after an overnight, that timeline is a problem. Jet lag is a circadian disruption, not just tiredness. Your body regulates sleep, alertness, digestion, and hormone cycles on a roughly 24-hour internal clock. Cross enough time zones fast enough and that clock is still running on origin time while your calendar is asking you to perform on destination time. The gap between those two things is what jet lag actually is. Eastbound vs Westbound: Why Direction Matters Eastbound travel is harder. Your internal clock adjusts more readily to a longer day - which is what westbound travel gives you, effectively - than to the shorter one that eastbound requires. Beaumont et al. (PubMed 12959951) measured this directly: eastbound travelers showed significantly greater performance decrements after rapid transmeridian travel than their westbound counterparts.* NYC to London, Chicago to Berlin, LA to Tokyo - those routes carry a steeper jet lag penalty. If you're the consultant flying Sunday night for Monday morning, you're working against the harder case. Worth building your caffeine strategy around that fact rather than around the assumption that a strong coffee on arrival will sort it out. Why Airport Coffee Isn't the Answer Terminal coffee has a branding problem: it looks like a solution because it's familiar and because airports have made it impossible to avoid. But an 8oz drip coffee can carry anywhere from 80mg to 150mg of caffeine depending on roast, brew method, and the specific terminal cafe's equipment on that particular morning. Order two, which most exhausted travelers do, and you might be at 300mg before you've cleared customs - without knowing it. That's not a caffeine strategy. That's guessing. The timing problem is where it gets more consequential. Caffeine's half-life runs roughly three to five hours, which means a 10 am coffee still has meaningful concentration in your system by mid-afternoon. If your destination's local bedtime is 10 pm and you're trying to resync your clock, caffeine at 3 pm is working against that process. There are also the purely logistical annoyances that add up on a travel day: the queue that eats into your boarding buffer, the hot cup you're managing through security while also handling a carry-on, the sugar-heavy airport cafe drink that front-loads energy for a crash an hour into the flight. None of that is helping. It's just familiar. The Science of Caffeine and Jet Lag Caffeine doesn't fix jet lag. Your circadian clock resynchronizes at roughly one time zone per day going eastbound, a little faster westbound, and no amount of caffeine changes that rate. What the research actually shows is something more specific and more useful: caffeine can meaningfully buffer the alertness deficit while your clock catches up. The Beaumont et al. study (PubMed 12959951) found that caffeine helped manage daytime sleepiness caused by jet lag, with the effect most pronounced on eastbound travel where the performance hit is sharpest.* That's a practical finding for arrival-day performance, even if it doesn't touch the underlying clock problem. A study in Science Translational Medicine (Burke et al., PMC4657156) added something that most travelers haven't heard: caffeine doesn't just mask fatigue - it has measurable effects on the human circadian clock itself, both in vivo and in vitro.* Timed well, it may actually assist the resynchronization process. Timed poorly - say, caffeine taken late evening at your destination - it can actively delay it. This is not a small distinction. The same dose of caffeine that helps you perform on arrival morning can make day-two adjustment harder if it disrupts your first night of local-time sleep. Caffeine's Half-Life and Why It Matters for Sleep The math is worth doing once so you don't have to think about it again. With a five-hour half-life, 100mg taken at noon is down to roughly 12.5mg by midnight. With a three-hour half-life - faster metabolizers, no genetic variants slowing clearance - that same dose is negligible by 9 pm. Most people are somewhere in between, which means a good rule of thumb is cutting off caffeine at least six to eight hours before your destination's bedtime. On arrival day in London after an overnight from New York, that's early afternoon at the latest. Earlier is better. For a detailed look at caffeine's effect on cognitive performance specifically, Neuro's pilot study on focus with BrainCo Inc. covers the measurement side of this in depth.* A Frequent Flyer's Discreet Energy Toolkit The jet lag conversation at the medical-authority level - Cleveland Clinic, Mayo, the PubMed literature - focuses on what caffeine does biologically. It doesn't usually address the practical question of format: how you're actually supposed to carry, dose, and time caffeine in an environment where you're moving through security, boarding a flight, and presenting slides within a twelve-hour window. Format is where Neuro Energy & Focus Gum solves a problem that brewed caffeine doesn't. Each piece contains 40mg of natural caffeine plus 60mg of L-theanine, B6, and B12.* The 40mg increment matters for dosing: you know exactly what you're taking, you can add a second piece an hour later if needed, and you're not committed to a full cup's worth at once. The Extra Strength version is 100mg per piece - roughly a standard drip coffee - for situations where you need that level and want the precision. The L-theanine pairing is worth understanding specifically. Owen et al. (PubMed 18681988) found that the combination of L-theanine and caffeine improved speed and accuracy on attention-switching tasks compared to caffeine alone.* A follow-up by Giesbrecht et al. (PubMed 21040626) replicated this and specifically noted reduced susceptibility to distraction.* If you're running on fragmented sleep and trying to hold a coherent thought in a client meeting, that specific effect - calmer, less scattered alertness - is more useful than the raw stimulation you'd get from caffeine alone. Neuro in a TSA-Safe Travel Kit Solid, fits in your pocket, no liquid rule, no spill risk. You don't need a free hand or a flat surface to use it. These are minor conveniences individually and they add up when you're navigating a connection with a carry-on in one hand and a boarding pass on your phone. The Energy & Focus Mints carry the same 40mg formula in mint format - same ingredient stack, different form factor for anyone who prefers it. Quick Reference: Caffeine Per Source Source Approx. Caffeine Airport latte (12 oz) 150-200mg (highly variable) Energy drink (standard can) 80-300mg (varies widely) Caffeine pill (standard) 100-200mg, no L-theanine Neuro Energy & Focus Gum 40mg per piece + 60mg L-theanine* Neuro Extra Strength Gum 100mg per piece + 60mg L-theanine* *Based on verified Amazon product listings and neurogum.com product pages. Caffeine Timing Playbook for Common Flight Scenarios Direction, departure time, and how many hours until your destination's midnight determine the caffeine strategy more than anything else. These aren't rules - they're starting points. Eastbound overnight (e.g., NYC to London): The goal in-flight is sleep, not alertness. Caffeine taken before boarding will still be active when you should be trying to rest. Skip it, or keep it very light before departure. On arrival - morning local time, probably after five or six hours of broken sleep in a window seat - one piece of Neuro Energy & Focus Gum gives you a controlled 40mg lift as you clear customs and find your hotel. Cut off entirely by early afternoon local time. Pushing through with more caffeine at 4 pm London time means you'll be wired when 10 pm arrives, and a bad first night makes day two harder. Westbound day flight (e.g., NYC to LAX): Westbound is the more forgiving direction. Your clock is being asked to extend the day, which it does more readily than compressing it. Small caffeine doses spaced through the afternoon - on arrival, not on the flight - help you stay on destination time without banking a large hit that lingers into the evening. LA bedtime is three hours later than New York, so you have more runway, but don't mistake that for permission to caffeinate through dinner. Domestic red-eye (e.g., SEA to JFK): Sleep on the flight if you can. That's the whole strategy for the first several hours. The caffeine question is really about the last hour before landing: one piece of gum gives you the alertness ramp for morning meetings without having pushed stimulants through your system all night. Arrive dehydrated, as most red-eye passengers do, and the fatigue reads worse than it actually is - hydration does more work per hour on arrival morning than a second piece of gum. Business traveler's morning meeting on arrival day: One piece of Extra Strength is 100mg - the equivalent of a standard drip coffee - but the dose is exact every time. The hotel lobby coffee might be 80mg or 140mg depending on who made it. Pair with a full glass of water, not more coffee. If you've already had two cups at the airport, track the total: 100mg on top of 200mg puts you at 300mg, which is still inside the FDA's 400mg daily guideline for healthy adults, but you're approaching it. Travel days are when the count gets away from people.* Flight Scenario Caffeine Approach Key Constraint Eastbound overnight Minimal in-flight; 1 piece on arrival morning Cut off 6-8 hrs before destination bedtime Westbound day flight Small spaced doses on arrival afternoon Later bedtime - don't push into evening Domestic red-eye Sleep in-flight; 1 piece near landing Hydrate before caffeinating on arrival Morning meeting, arrival day 1x Extra Strength (100mg); track daily total Know your running total across all sources What to Pack for Discreet Focus Caffeine is one input. Jet lag is a circadian disruption problem, which means it responds to multiple signals - light, food timing, activity, and yes, caffeine - but it's not solved by any one of them alone. For the caffeinated phase of the day, Neuro Energy & Focus Gum at 40mg increments gives you the flexibility to dose up or down based on how you're actually responding. On arrival mornings, whether you’re feeling functional or not, Neuro Energy & Focus Gum, with 40mg of caffeine, lets you adjust without committing to a full coffee's worth.* For evening arrivals or the wind-down portion of the day, the caffeine-free Memory & Focus Gum contains Cereboost Ginseng and L-theanine for cognitive support without sleep interference. When you still have a few hours of emails before bed but can't afford to push your sleep later, Memory & Focus Gum is useful for a late-arriving flight.* A refillable water bottle is probably the most underrated item on this list. Cabin air at altitude is extremely dry, and most long-haul passengers arrive dehydrated even if they didn't have a single drink—often without recognizing it. Dehydration amplifies fatigue, headache, and cognitive fog in ways that look like jet lag but respond to water, not caffeine. Drink before you reach for the gum. Blue-light blocking glasses are optional, but the mechanism is real: blue light suppresses melatonin production and signals "daytime" to your circadian clock. Wearing them before destination bedtime—on the plane, in the lounge, or on the way from the airport—reinforces the sleep signal. If your doctor has recommended melatonin for jet lag, it's serving a different function than caffeine. Beaumont et al. (PubMed 12959951) specifically examined both compounds in the transmeridian travel context - they're complementary tools, not alternatives. What doesn't belong in the travel kit is the expectation that caffeine substitutes for sleep. It doesn't, and leaning on it too hard on day one makes the resync harder on days two and three. When to Skip the Caffeine Altogether Not every landing warrants a caffeine strategy. There are a few specific cases where leaving the gum in your bag is the smarter call. Short trips - 24 to 48 hours, back to the same time zone by Thursday - often don't warrant resynchronization at all. If your body holds home time, there's less to undo when you land back. Pushing to adjust for two days and then reversing it is sometimes more disruptive than just tolerating the slight offset. If you've already hit or approached 400mg from other sources across the day - which is easy to do on a travel day with hotel breakfast coffee, airport coffee, and a soda at lunch - adding more isn't the move. Track the total. It's the aggregate that matters, not any single source. And some of what passes for jet lag on day two is just sleep debt from a short or uncomfortable night. Caffeine can support performance through it, but the underlying deficit resolves with sleep, not stimulants. Sometimes the most effective jet lag strategy is getting to bed at local time on arrival night and accepting a slow morning. Frequently Asked Questions Can I bring Neuro Gum and Mints through airport security? Yes. Gum is a solid and is not restricted by TSA's 3.4-oz liquid rule. Always check your destination country's customs rules for any supplements. Will caffeine gum actually help my jet lag? Research suggests caffeine can help manage daytime sleepiness associated with jet lag, particularly for eastbound travel.* It doesn't cure jet lag, but it can support alertness at strategic moments - like an important meeting right after landing. How is Neuro different from caffeine pills? Neuro Energy & Focus provides 40mg of caffeine per piece, while Neuro Extra Strength Energy & Focus steps that up to 100mg, both paired with 60mg L-theanine, B6, and B12 - a multi-ingredient formula that caffeine-only pills don't offer (verified Amazon product listings).* The L-theanine pairing has published research support for improving focused, calmer alertness compared to caffeine alone. Is there a version I can take on evening flights without wrecking my sleep? Yes. Neuro Memory & Focus Gum is caffeine-free and contains Cereboost Ginseng, L-theanine, B6, and B12 - suitable for when you want cognitive support without caffeine's sleep interference.* Can I use Neuro as my only jet lag strategy? No single product fixes jet lag. Caffeine is one tool - hydration, light exposure, meal timing, and strategic sleep all matter. For severe or recurring jet lag, consult your healthcare provider. Ready to Travel Smarter? The medical sites will tell you what jet lag is. This is what to actually put in your bag. The Neuro Bundle covers the full arc: caffeinated focus for arrival day, the standard 40mg daily dose, and the caffeine-free wind-down for when you're trying to push your sleep toward local time without losing all cognitive function in the process. *These statements have not been evaluated by the Food and Drug Administration.

Learn moreHow to Make the Most of Your Summer: Bucket List Ideas & Tips to Stay In It
Summer has a sneaky quality: it feels infinite in June and somehow already nostalgic by August. One minute you're making ambitious plans — weekend road trips, sunrise hikes, backyard cookouts that stretch into the evening — and the next, you're wondering where July went. Making the most of summer doesn't just happen. It takes a little intention. And a lot less running on empty. No matter if you're looking for summer bucket list ideas to share with friends, weekend plans that don't require a full week of recovery, or just a way to actually feel present during the season you've been building toward all year, this is your guide. Why You Deserve to Enjoy Summer Most adults don't fully stop in the summer. You're still showing up, still juggling everything, but the season carries a real permission to slow down, go outside, and be a little less serious about the serious stuff. There's a reason you feel genuinely better after a weekend in the woods or a few hours at the beach. Time outside clears the mental noise, and time with people you actually like fills something back up. Summer is one of those rare windows where both happen naturally, which makes it worth showing up for, not just surviving. How Can I Make the Most of Summer? If you're asking this, you're already ahead — because you're approaching it with intention instead of letting summer just happen to you. Here's what actually works. 1. Decide what summer means to you this year. Not what it looked like last year or what your social feed says it should look like. More rest? More adventure? More quality time with specific people? Start there before you start planning. 2. Set a few anchor moments — and commit to them. You don't need to schedule every weekend. But 3–5 non-negotiable plans give your summer shape and something to look forward to. These become the markers that make the season feel full instead of fast. 3. Use the weekdays too. Summer isn't only weekends. Have dinner at that outdoor spot you've been meaning to try. Say yes to a Tuesday concert. Meet your friends after work instead of catching up over text. The weekdays are where summer either slips by or gets lived — small decisions turn ordinary days into something worth remembering. 4. Be present when you're in it. You can do all the right things and still miss them if you're mentally somewhere else. Put the phone away. Be in the conversation, on the trail, at the table. Presence is the whole point. 5. Fuel yourself to stay in the game. A packed calendar is useless if you arrive to everything already running on empty. Sleep and hydration are obvious — but for those long afternoons where you still have a cookout, a concert, or a sunset hike ahead, it helps to have something that keeps you sharp without overdoing it. Neuro's new Energy & Focus Gum in Watermelon is worth keeping in your bag. It's a smart gum — natural caffeine, L-theanine, and B vitamins in a lighter 20mg dose that gives you a clean, focused lift without the crash. Summer companion energy, not a morning stack replacement. Zero sugar, tastes like summer. Neuro Energy & Focus Gum Watermelon (Limited Edition) — a fresh, juicy take on clean energy, with natural caffeine, L-theanine, and B vitamins. Find it at the Neuro website. 6. Don't wait for the "right" weekend. The perfect plan is the one you actually execute. A spontaneous afternoon at a new park will outlast a meticulously planned trip that never gets booked. Start small, start soon. Summer Bucket List Ideas for Adults (That Actually Happen) Think of this less as a checklist and more as a permission slip. Pick what lights you up. Leave the rest. Water Everything Spend a full beach or lake day with zero agenda — no itinerary, just water and your friends/family Try paddleboarding, kayaking, or an open-water swim for the first time Set up a backyard slip-and-slide (yes, even as an adult — especially as an adult) Catch an outdoor movie at a rooftop cinema or drive-in Track down a waterfall within driving distance and actually go Get Outside for Real Plan a sunrise hike — trails are quieter, temperatures are cooler, and the light is unmatched Hit a farmers market in a neighborhood you've never been to Book one camping night — even a single night is enough to reset everything Try outdoor yoga or an early morning run in a new part of your city Go stargazing somewhere with low light pollution Summer Culture Catch an outdoor concert or free music festival — most cities have more of these than people realize Explore a food truck festival or neighborhood block party Take a cooking class centered on a seasonal ingredient (extra points if grilling is involved) Visit a state or national park you've never been to Go to a baseball game — there is simply nothing more summer than a baseball game Make It Social Host a backyard cookout with an actual theme Plan a sunset picnic with your favorite people and zero screens Start a summer book club: one book, one outdoor meetup per month Do a road trip — even three hours away counts, and the car conversations are always the best part Volunteer for a local outdoor community project How to Make the Most of a Long Weekend If you're an adult trying to actually use your weekends instead of recovering from the week, this is for you. Experiences that feel intentional without feeling like a second job. Here are some suggestions for each day. Friday Night: A real dinner, an after-dinner walk, and an early enough night so Saturday morning actually feels good. Saturday Morning: Before the heat and the phone start competing — farmers market, slow coffee, porch time. Don't scroll. Saturday Afternoon: Half-day hike, day trip to a nearby town, afternoon on the water. One good afternoon beats three mediocre evenings. Sunday: Slow morning, something outdoors, a good meal, one small thing that sets up your week. A great Sunday changes everything. The Best Summer Outdoor Activities Summer outdoor activities don't have to mean training for anything. The best ones are the ones you actually do and enjoy enough to do again. When You Want to Move Hiking — Even a 2-mile trail with a good view counts Swimming — Open water, lake, or pool; the one cardio that never feels like cardio Pickleball or tennis — Easy to pick up, genuinely social, and addictive in the best way Trail running or cycling — Better in summer than any other season Outdoor fitness classes — Many parks offer free boot camps and yoga all summer long When You Want to Be Outside Without Trying That Hard Hammocking in a park — deeply underrated Outdoor reading with a cold drink somewhere with actual shade Birdwatching — genuinely meditative once you try it Lawn games: bocce, cornhole, croquet, ladder toss Sunset watching from somewhere intentional — pick a great spot, show up, sit down When You Want to Learn Something New Take a paddleboard or surfing lesson Try outdoor rock climbing with an intro session at a local gym Join a trail running group for a guided group run Sign up for a foraging walk with a local naturalist guide Take a cooking class built around summer produce The Bottom Line Summer rewards effort to plan something, show up for it, and stay present enough to actually experience what you've built. You don't need a perfect plan. You need a few good ones, the energy to see them through, and the presence of mind to be there when they happen. Your smarter summer starts right now. Don't let August be the thing that reminds you it was possible. Ready to stay in it all summer long? Grab Neuro Energy & Focus Gum in the new limited-edition Watermelon flavor! Clean energy, zero sugar, and the taste of summer in every piece.
Learn moreZero-Sugar Energy That Won't Spike Your Blood Sugar
At your desk at 2:00 PM, feeling drained already. However, a ton of work awaits: emails to respond to, reports to analyze, an article to finish, or you must maintain your focus on studying. You reach out to your ice-cold, fizzy, sugary energy drink. You feel refreshed. It does the job—until it doesn’t. After half an hour, the inevitable happens. Your eyelids get heavy. The brain fog rolls in. You're suddenly more exhausted than you were before you popped the tab. Now, you have lost your focus and boarded the blood sugar rollercoaster. You need 'good energy' rather than high-octane intensity. If you are tired of the afternoon slump, it is time to look closely at what is fueling you. The Hidden Cost of Sugar-Fueled Energy Traditional energy drinks and sugary snacks are designed for a quick thrill, not sustained performance. When you consume heavily sweetened beverages, your body experiences a rapid blood sugar spike. The sudden surge caused by these beverages or snacks forces your pancreas to release excessive amounts of insulin to bring those glucose levels back down. Often, the insulin overreaction leads to a sharp drop in blood sugar, known as reactive hypoglycemia. As a result, abruptly, your energy levels hit rock bottom, and you crave more sugary fixes. It is a vicious cycle. And keep in mind that "reduced sugar" is not the same as "zero sugar." Even moderate amounts of added refined sugars can initiate this spike-and-crash loop. What "Sugar-Free" Really Means (and What to Watch For) If you think "sugar is the problem, so the solution should be sugar-free," think again. Not all "sugar-free" labels are created equal. The type of sweetener matters for your metabolic health. Stevia: Extracted from plant leaves, stevia has no measurable effect on fasting glucose levels, according to research (Stamataki et al., 2020). Xylitol: This sugar alcohol has a glycemic index (GI) of approximately 7, compared to table sugar's GI of 65. While it has a minimal glycemic impact (Natah et al., 1997), individual responses can vary. Monk Fruit: A natural sweetener that may reduce post-meal glucose responses. Aspartame: Many diet sodas and gums have this ingredient, but it has raised concerns regarding its metabolic effects. At Neuro, we prefer clean, natural alternatives. That is why Neuro Energy & Focus Gum is sweetened entirely with xylitol, monk fruit, and steviol glycosides. Zero aspartame. Zero sugar. 5 Sugar-Free Ways to Power Through Your Day Sugar is certainly a useful ingredient for quick boosts of energy and focus, but its impact is limited and appropriate only for certain situations. If you want more 'uptime' during the day, without the midday meltdown, you need smarter solutions. Start Your Morning With Protein, Not Carbs You know the drill. You wake up, grab a pastry or a bagel, and rush out the door. It feels amazing for about an hour. Then 10:00 AM hits, and you are completely wiped out. Why does it happen? While carbohydrates break down rapidly into sugar and flood your bloodstream, protein provides a gradual energy release. So, you save yourself from the loop. If you swap the cereal or pastry for eggs, a protein shake, or Greek yogurt, your future self will thank you. Hydrate Before You Caffeinate Brain fog often masquerades as exhaustion. In reality, you are probably just dehydrated. Water is absolutely essential for basic cellular function. When you lack water, your body has to work overtime, which quickly drains your energy reserves. Before you even think about pouring that first cup of coffee, drink a large glass of water. Keep a bottle on your desk. Make it a habit. Pair Your Caffeine With L-Theanine We all love the caffeine lift. We hate the jitters and the inevitable crash. The relationship between caffeine and blood sugar is anything but ordinary. However, we pair natural caffeine with L-theanine, an amino acid that smoothes out psychological spikes caused by caffeine, changing the game. Studies (Spaulding & Yan, 2022) suggest L-theanine regulates glucose via AMPK signaling, offering possibilities for metabolic support. When you consume products that combine both ingredients, you get calm clarity without anxiety. Snack Smart With Low-Glycemic Foods It's 3:00 PM. You hear the vending machine shouting your name. Don't do it. Sugary snacks cause a rapid glucose spike followed by a massive insulin dump. That insulin overreacts, dropping your blood sugar sharply and leaving you hungrier and more tired than before. Low-glycemic foods bypass this reaction entirely. Smart snacks, such as almonds, pumpkin seeds, or string cheese, satisfy the craving without triggering the spike-and-crash cycle. Don't Do Cans, Use Functional Gum Instead Energy drinks are a trap. They promise the world but deliver a sticky, sugary mess. Your body absorbs liquid sugar incredibly fast, causing a quick rise and a hard fall. Chewing functional gum provides a clean lift without the liquid volume or the sugar. It's pocket-sized, discreet, and puts you entirely in control of your focus. Why Functional Gum Is the Cleanest Energy Format Let's evaluate your possible energy sources. Energy drinks are bulky, messy, and packed with questionable ingredients. Energy bars and other sugary sources are pretty much the same. We all love coffee, but it can leave you with the jitters. Functional gum is different. Every piece of Neuro Gum contains 0g of sugar, utilizing only xylitol, monk fruit, and stevia. The formula delivers 40mg of natural caffeine and 60mg of L-theanine to support mental endurance without the tremors. It is keto-friendly, vegan, and completely free of aspartame. We even put our formulation to the test in a pilot study with BrainCo Inc. to ensure it delivers the focus you need. Need a bigger lift? Extra Strength Gum provides 100mg of caffeine per piece. Looking to stay dialed in late at night? Memory & Focus Gum is caffeine-free and sugar-free. We also offer Energy & Focus Mints if that is more your speed. Building Stable Energy Habits (Beyond What You Chew) Of course, depending on supplements is not enough for good, clean energy. You must adopt a lifestyle to reinforce your well-being. If you want to feel present and capable all day, you need to look at the big picture. Guard Your Sleep Schedule High-quality sleep is the foundation of daytime energy and cognitive function. All the clean energy supplements won't be enough to hack it. A good night's sleep is a must for clearing out metabolic waste and consolidating memories. Rethink Your Meal Content A massive, carb-heavy lunch is a one-way ticket to sleep town. When you consume large, high-glycemic meals in the middle of the workday, your digestive system demands a massive share of your body's resources. Move After You Eat Going back to your desk immediately after lunch is one of the worst mistakes if you want to stay sharp until the end of your workday. Taking (at least) a 10-minute walk after meals helps your muscles absorb glucose from your bloodstream, naturally regulating your blood sugar levels and keeping your energy steady. Set a Caffeine Curfew Caffeine is a brilliant tool, but it has a half-life. If you consume it too late in the day, it will wreck your sleep architecture, practically guaranteeing you will wake up exhausted the next day. Restrict your caffeine intake to the morning and early afternoon. Take B Vitamins B vitamins help your body convert nutrients into usable cellular energy. Consuming foods rich in B vitamins or taking supplements containing B6 and B12 supports that process. FAQ Does xylitol spike blood sugar? Xylitol’s glycemic index is approximately 7, compared to table sugar's 65. Research indicates it has a minimal effect on blood sugar and insulin levels in most people. How much caffeine is in Neuro Gum and Mints? Energy & Focus Gum contains 40mg of natural caffeine per piece. Extra Strength contains 100mg. Memory & Focus Gum is caffeine-free. Can I use Neuro on a keto diet? Yes. Neuro Gum contains 0g sugar and 0g net carbs, making it fully compatible with ketogenic and low-carb diets. What sweeteners does Neuro use instead of sugar? We use xylitol, monk fruit extract, and steviol glycosides. We never use aspartame. Ditch the sugar crashes and fuel your day with clean, sustained focus.
