If you’ve ever stood behind the counter at a convenience store at 2 a.m., restocking energy drink shelves and watching a line of college students cram for midterms, or a construction crew grabbing a quick pick-me-up before a 10-hour shift, you’ve probably noticed one big truth: not everyone reacts to the same stimulant the same way. As someone who’s spent the last 12 years in the other stimulants supply business, I’ve heard every story—from the kid who drinks one 5-hour energy and crashes by lunch, to the truck driver who relies on a daily dose of a certain botanical stimulant to stay alert on cross-country runs. This isn’t just a “some people are different” observation; it’s the kind of nuance that makes our work as suppliers less about moving product and more about helping different groups find what actually works for them. Let’s break down the real, science-backed differences in how other stimulants affect distinct populations, and why that matters for everyone from consumers to the brands that work with us. Other Stimulants
First, let’s clarify what I mean by “other stimulants” here, because a lot of people lump caffeine in with every pick-me-up, but there’s a whole category of stimulants beyond coffee and soda that make up most of our supply. Think things like yerba mate, guarana, green tea extract, cordyceps, and even smaller quantities of caffeine from natural, plant-based sources—all stimulants that don’t fall into the “synthetic caffeine” or high-dose amphetamine-adjacent categories that get most of the media attention. I got into this business after my dad, who ran a small natural health brand in the Pacific Northwest, noticed that his customers’ feedback about energy supplements was all over the place: one mom said a green tea-based pill gave her enough energy to chase her toddler and fold laundry, while another said it made her jittery and gave her a racing heart. That experience taught me early on that stimulant effects aren’t one-size-fits-all—they’re shaped by biology, lifestyle, and even how someone’s body processes these substances.
Let’s start with one of the most well-researched groups when it comes to stimulant response: adolescents and young adults. For years, researchers have known that teenage brains are still developing, particularly the prefrontal cortex, which regulates impulse control, attention, and response to neurotransmitters like dopamine. A 2022 study out of the University of California, San Francisco, found that adolescents who consume high doses of natural plant-based stimulants (like guarana or yerba mate, which often have similar caffeine content to a cup of coffee) are 30% more likely to experience heightened anxiety and disrupted sleep patterns compared to adults. Why? Because the dopamine receptors in teen brains are still maturing, so stimulants that boost dopamine levels more sharply (like guarana, which releases caffeine slowly over time but can still hit a high peak if consumed in large amounts) can overload that developing system. What I’ve seen in my work is that brands targeting teen and young adult audiences often come to us asking for lower-dose formulations, or blends that pair stimulants with adaptogens like ashwagandha to buffer the jitters. That’s not just a marketing trend—it’s responding to real physiological differences. I once worked with a college wellness brand that swapped their original 200mg guarana-only shot for a 100mg yerba mate + L-theanine blend, and their customer complaints about jitters dropped by 70% in six months. That’s the kind of impact that comes from understanding population-specific needs.
Next up: older adults, a group that’s often overlooked in stimulant research, but whose bodies process stimulants very differently. As we age, liver function declines, specifically the enzymes that break down caffeine and many plant-based stimulants. A 2019 study in the Journal of the American Geriatrics Society found that adults over 65 metabolize natural stimulants about 50% slower than adults in their 20s and 30s. That means a stimulant that gives a 25-year-old a 4-hour energy boost can give a 68-year-old a 8-10 hour boost, often leading to nighttime insomnia, which is already a common issue for older adults. What’s more, many older adults take prescription medications—blood thinners, antidepressants, or cholesterol drugs—that can interact with stimulants. For example, theophylline, a stimulant found in small amounts in tea and some botanical blends, can interact with beta-blockers, which many older adults take for heart health, leading to elevated heart rate. That’s why we’ve started developing a line of low-dose, gentle stimulant blends specifically formulated for older adult-focused brands, with 50mg or less of natural stimulant content, paired with mild adaptogens to support alertness without disrupting sleep. Last year, I worked with a senior care services brand that tested our low-dose green tea extract blend for their evening activity sessions, and 82% of the participants reported feeling more alert without the next-day grogginess they’d had from traditional coffee. That’s a win that I never would have predicted when I first started in this business.
Then there’s the group I see most frequently in our bulk orders: people who work physically demanding jobs, like construction, long-haul trucking, or agriculture. This population has very different stimulant needs than desk workers or students, because their physical output is higher, and they often work long hours in harsh conditions. What many people don’t realize is that physical exertion changes how the body processes stimulants. A 2021 study in the Journal of Applied Physiology found that when the body is under physical stress, blood flow shifts away from the liver to the muscles, slowing down metabolism of stimulants by up to 30%. That means a stimulant that works as a 6-hour boost for a sedentary worker can last 8-10 hours for a construction worker, which might sound good, but can lead to overstimulation, elevated blood pressure, and even dehydration in hot weather. But here’s the catch: for physically active people, low-dose stimulants paired with electrolytes can actually be beneficial, helping to reduce fatigue and improve reaction time without the jitters. We work with a lot of trucking companies and construction supply brands, and they often ask for stimulant blends that are timed-release, with added electrolytes, so drivers can take one dose at the start of a 12-hour shift that lasts just long enough, without leaving them wired at the end of the day. One trucking brand I partner with told us that their drivers used to buy high-sugar energy drinks that left them crashing at rest stops, but our guarana + electrolytes blend has cut driver fatigue-related incident reports by 22% in their fleet over two years. That’s the kind of real-world impact that makes this job feel meaningful.
Another underdiscussed population is neurodivergent individuals, particularly those with ADHD or anxiety. This is a group that I’ve gotten a lot of requests from over the last few years, and the feedback is really eye-opening. For people with ADHD, stimulants work differently because of differences in dopamine regulation. Most ADHD medications are stimulants for that reason, but many people prefer natural stimulants over prescription meds for various reasons. A 2023 study in the Journal of Attention Disorders found that people with ADHD often respond well to low doses of natural stimulants like cordyceps or green tea extract, which have a milder dopamine-boosting effect than synthetic stimulants, but that higher doses can actually worsen inattention, not improve it. For people with anxiety, stimulants—even natural ones—can trigger or worsen anxiety symptoms, because they increase cortisol, the stress hormone. But we’ve found that when you pair low-dose stimulants with adaptogens like rhodiola or holy basil, that can balance out the cortisol response. I worked with a neurodivergent mental health brand last year, and they developed a blend of 75mg cordyceps + rhodiola extract that’s now one of their top-selling products. They told us that many of their customers, who had tried prescription stimulants that caused side effects or natural blends that were too strong, reported feeling focused without the racing heart or anxiety. That’s the kind of innovation that comes from listening to a specific group’s needs, not just following generic industry trends.
Of course, none of this is to say that stimulants are without risks for any population. Even natural stimulants can have side effects if not dosed properly, and individual differences in genetics, diet, and other factors can play a role too. For example, some people have a genetic variant that makes them metabolize caffeine very slowly, so even a small amount of stimulant can cause jitters, while others metabolize it very quickly and need higher doses to feel any effect. That’s why our team as suppliers focuses a lot on transparency, providing clear dosing guidelines for different populations, and working closely with brands to customize blends for their specific customer base. We don’t do one-size-fits-all, because we’ve seen too many times how that falls flat.
Over the years, I’ve heard all sorts of myths about stimulants: that natural is always better, that stimulants are bad for kids, that older adults shouldn’t use them at all. But the reality is a lot more nuanced, which is what makes this industry so interesting. The differences in how stimulants affect different populations aren’t just scientific data points—they’re real people: the college student pulling an all-nighter who doesn’t want to crash before their exam, the construction worker putting in 10-hour days in 90-degree heat, the older adult who wants to stay alert for their grandkid’s soccer game, the neurodivergent person who’s looking for a way to focus without the side effects of prescription meds.
As an other stimulants supplier, our job isn’t just to provide a consistent product. It’s to understand the unique needs of different groups, translate that into formulations that work for them, and be a partner to brands that want to create products that actually help people, not just sell a quick fix. If you’re a brand owner, a healthcare provider, or someone looking to develop a product that caters to a specific population, we’d be happy to discuss your needs, share our research, and help you create something that balances effectiveness, safety, and individual differences. Whether you’re targeting teens, older adults, physically active workers, or neurodivergent communities, we have the expertise to support your goals.
