Nootropics: what belongs in the category?

It's the fourth hour of a late session, or the afternoon before a deadline, and the shop shelf has a product with "nootropic" on the tub. Next to it sits an energy drink, a tea and a pack of capsules with a brain on the label. Which of these is the nootropic? Possibly all of them, possibly none. That's the fun problem with the word, and it's worth sorting out before you read a single ingredient list.

Here's the plain version: "nootropic" is a label, not a safety class and not an evidence grade. It was coined in the early 1970s for one specific idea about one specific compound, and it now stretches over everything from caffeine to botanical extracts to prescription medicines taken without a prescription. Those groups are regulated differently, studied differently and carry different risks, so the useful move is to sort the product first and judge the claim second.

Where the word came from

The term was introduced by the researcher Corneliu Giurgea in 1972 (some sources give 1972 or 1973 for the early papers). A 2022 review in Nutrients by Malík and Tlustoš traces it to the Greek nous (mind) and tropein (to guide), and says Giurgea used it for substances that activate cognitive functions such as memory and learning, especially where those functions are impaired (Malík and Tlustoš, Nutrients, 2022). A second review places the coinage at the point when piracetam was found to have memory-enhancing properties in clinical trials (Napoletano and colleagues, Frontiers in Psychiatry, 2020).

Notice what's missing from that story: gaming, productivity and shopping categories. Malík and Tlustoš add that there's no single agreed way to sort these compounds. Some authors separate "classical nootropics" from substances that raise brain metabolism, and others avoid the word and talk about cognitive effects instead. So when a shop calls something a nootropic, it's using a term that researchers themselves don't apply consistently.

Three kinds of product under one word

It helps to swap "is it a nootropic?" for "what kind of product is this?" Here are the three groups you'll meet.

• Group: Everyday stimulants; Examples: Caffeine in coffee, tea, energy drinks and some capsules; Rules in the Netherlands (read 8 October 2026): Sold as food; What to ask: How much caffeine in total, across the whole day?
• Group: Food supplements and botanicals; Examples: Amino acids such as L-theanine, plant extracts such as ginkgo, mixed "focus" blends; Rules in the Netherlands (read 8 October 2026): Food law; for herbal supplements, no efficacy or safety assessment before sale; What to ask: Which ingredient, how much, and was this preparation studied?
• Group: Prescription medicines used as "smart drugs"; Examples: Methylphenidate, dexamfetamine, modafinil; Rules in the Netherlands (read 8 October 2026): Medicines, on prescription; What to ask: Why take a medicine meant for a diagnosed condition without a prescriber?

The last row gets its own section further down.

What would a convincing answer look like?

Before looking at any ingredient, it helps to agree what good evidence for "better focus" would involve. A few questions do most of the work:

• What was measured? "Better focus" can mean faster responses on a computer task, fewer errors on a vigilance test, a feeling of alertness on a questionnaire, or better results in real life. Those are four different outcomes.
• Who took part? Young healthy volunteers, older adults and people with a diagnosed condition aren't interchangeable.
• Compared with what? A placebo, the same dose of caffeine alone, or nothing.
• How big, and how certain? The US National Center for Complementary and Integrative Health (NCCIH) points out that a result can be statistically significant while the difference is too small to matter in practice, and that a single study rarely provides a final answer (NCCIH, How to make sense of a scientific journal article: results).
• Was it the same product? An extract in a trial isn't the same as a blend with the same plant name on the label.

One example shows why this matters. In a placebo-controlled trial of 44 young adults, a combination of 97 mg L-theanine and 40 mg caffeine improved accuracy on a task-switching test and self-reported alertness. It had no significant effect on visual search, choice reaction time or mental rotation (Giesbrecht and colleagues, Nutritional Neuroscience, 2010). Same people, same capsule, several tests: a clear result on some, nothing on others. "Improves focus" would be too broad a summary.

What research in healthy adults has found

Most nootropic research began with people who have impaired cognition. Healthy adults are a different question, and the answers are less tidy, so the findings below are narrow ones.

Prescription "smart drugs." A 2022 review of amphetamine-type stimulants, methylphenidate, modafinil, piracetam and related compounds in healthy people found that users generally perceive them as effective, but that efficacy in healthy individuals is uncertain and reported improvements are temporary. The same authors describe possible cardiovascular, neurological and psychiatric complications, and addictive behaviour (Schifano and colleagues, Drugs, 2022). For modafinil specifically, a systematic review of studies in healthy people who weren't sleep-deprived found that basic tests often showed better executive function, only about half showed gains in attention, learning and memory, and a few reported poorer divergent (creative) thinking; more complex tasks looked more consistently positive (Battleday and Brem, European Neuropsychopharmacology, 2015). The authors themselves flagged that the studies were methodologically uneven.

For methylphenidate, Drugs en Uitgaan, the Dutch drug-information service, says there is not yet clear scientific evidence that non-prescribed use really improves concentration in people who don't need it, and that the placebo effect seems to play a role (Drugs en Uitgaan, Methylfenidaat).

Ginkgo. NCCIH says ginkgo supplements have been marketed for "brain health", but it's uncertain whether they influence cognitive performance in healthy people. In its large trial in people aged 75 or older, ginkgo and placebo groups developed dementia at similar rates (NCCIH, Ginkgo, updated February 2025). That's a different question from focus in a gaming session, but it shows how a famous name can run ahead of the evidence.

Caffeine with L-theanine. This is one of the more studied supplement pairings in the "focus" space. A 2025 systematic review of randomised trials in healthy participants found small-to-moderate differences versus placebo on some attention tasks in the first two hours after a dose, with confidence intervals that often left the size of the effect uncertain, and with much of the underlying evidence at high risk of bias (Payne and colleagues, Nutrition Reviews, 2025). The trials measured short laboratory tasks, not hours-long sessions or exam results.

Multi-ingredient blends. A blend inherits nothing automatically from its best-studied ingredient. If a product lists a dozen ingredients, each needs its own evidence at the amount in the product, and the combination needs its own too.

Smart drugs versus supplements: where the Dutch line sits

The core difference is simple to state. A medicine has a medical purpose and goes through a regulator before it can be sold; a food supplement is a food. In the Netherlands, the Medicines Evaluation Board (CBG) explains that herbal medicines need its approval before sale, whereas herbal supplements fall under food law and don't need an efficacy and safety assessment before they go on the market. According to the same page, supplements can't have a medical indication, although health claims are allowed (CBG, Kruiden).

What that means for each group, as of 8 October 2026 and for the Netherlands only:

• Methylphenidate is on List I of the Opium Act; possessing or trading it without a doctor's prescription is prohibited, according to Drugs en Uitgaan. Trimbos says ADHD medication is only available on a doctor's prescription in the Netherlands and that methylphenidate and dexamfetamine are on List I (Trimbos, July 2022). The same page reports that almost one in twenty students used ADHD medication without a prescription in the past year.
• Modafinil is, in the words of the Dutch government's April 2020 reply to parliamentary questions, a medicine "only available on prescription". The government called non-medical use without a prescription undesirable and said reports to the health inspectorate show illegal trade in ADHD medication and modafinil (Kamervragen, Aanhangsel 2019-2020, nr. 2408). That reply is more than six years old and doesn't say whether possessing modafinil without a prescription is an offence, so check the Dutch government's current wording.
• Racetams and other compounds sold online as "nootropics" are a separate question: their Dutch and EU status isn't covered here, so check the CBG or the health inspectorate (IGJ) before buying. A product turning up in a web shop tells you nothing about its status, its quality or what's actually in it.

Dutch rules aren't EU-wide, and laws change; this is not legal advice. If you're outside the Netherlands, or reading this well after October 2026, check the current rules for your country.

Safety essentials, whatever the label says

Count caffeine across the whole day. The European Food Safety Authority (EFSA) assessed caffeine in 2015. Its page says intakes up to 400 mg per day, spread through the day, don't raise safety concerns for healthy adults, and single doses up to 200 mg from all sources don't either. For pregnant women it gives 200 mg per day from all sources. It also says single doses of 100 mg may affect sleep in some adults, particularly close to bedtime (EFSA, Caffeine, assessment published 27 May 2015). Those are assessment figures for healthy populations, not personal targets. A "focus" capsule on top of an energy drink and a coffee adds up. If sleep is the thing you're trying to fix, our sleep hygiene guide is a better start than another stimulant.

"Natural" doesn't settle it. NCCIH puts it plainly: "natural" does not always mean "safe", and some supplements can harm you if you have a particular medical condition or take certain medicines (NCCIH, Using dietary supplements wisely). Ginkgo, for instance, may raise bleeding risk in people on anticoagulants such as warfarin, according to NCCIH's ginkgo page above. Our guide to supplements and drug interactions explains how to check a combination with a pharmacist.

Prescription stimulants aren't a shortcut. The reviews above describe real harms, and in the Netherlands, getting them without a prescription means going outside the regulated supply. If you're struggling to concentrate, the route is a doctor.

Persistent memory or concentration problems deserve a conversation. The NHS advises seeing a GP if memory problems affect day-to-day life, and lists stress, anxiety, depression and insomnia among common, treatable causes (NHS, Memory loss). A supplement shouldn't stand in for that.

What gamers and focused workers tend to ask

• Your question: "Will a nootropic keep me sharp through a long session?"; What the research can tell you: Caffeine is the most familiar part of most "focus" products, and the sleep trade-off is real. For other ingredients, evidence in healthy adults is thin or measured on short lab tasks.
• Your question: "Does it improve reaction time?"; What the research can tell you: Some short trials of caffeine with L-theanine measured reaction-time outcomes in healthy adults, with mixed results by task. A lab trial in healthy volunteers isn't a test of a ranked match.
• Your question: "Will it help me study or work better?"; What the research can tell you: The trials measured selected lab tasks, not exam marks or output at work.
• Your question: "Is it safe to stack several?"; What the research can tell you: Combining products adds caffeine and interaction questions. Take the actual labels to a pharmacist.

Reading the label on a "nootropic"

Start with the label. Under EU rules a food supplement label must show the recommended daily portion, a warning not to exceed it, a statement that supplements shouldn't replace a balanced diet, and a warning to keep it out of reach of young children (Your Europe, Supplement labelling rules). Our guide on how to read supplement labels covers the rest.

Then check four things:

1. Is every ingredient listed with an amount? A named blend with one total weight doesn't tell you how much caffeine you're getting.
2. Does the amount match what a study used? If a page cites a trial, compare the dose, preparation and outcome.
3. Is the claim about the product or about an ingredient? "Studies show X" about an ingredient isn't a trial of the finished product.
4. Is the claim a promise? If it says it will boost performance, ask what was measured.

A label as an example. MADMONQ is a gaming-positioned brand. Its product page, checked 8 October 2026, lists for its tablet caffeine (including a "targeted-release" form), L-theanine, L-tyrosine, rhodiola, schisandra, choline and zinc, among other ingredients. That's supplier information about what is in the product, not evidence that it does anything, and we haven't verified the Dutch pack, so check the exact variant before comparing it. The useful next step is the same for any blend: find the amount of each ingredient on the label before comparing it with a trial, and don't apply caffeine-plus-L-theanine trials to a mix with this many other ingredients.

Sorting the shelf: treat the word as a question

Treat "nootropic" as a prompt to ask questions, not as an answer. Caffeine, a botanical extract and a prescription stimulant are three separate propositions with separate evidence, risks and rules. For healthy adults, the best-supported claims are narrow (a short lab task, a short window after a dose) and often small, and none of the research above shows better productivity or better play. The dull habits still do the heavy lifting: sleep, breaks, and a doctor's visit if the problem persists.
