Below is a guide that discusses types of nootropics and smart drugs, their different categorizations according to the effects, and the group to which they belong. We also want to provide you with a complex library of 85 researched nootropics. All in one place.
Alternance and variety are the default mode of the whole human experience. Whether we know it or not, almost everyone uses different types of nootropics and smart drugs to improve memory, focus, energy, and mood.
The caffeine, green tea, fish oil, vitamin B, choline, creatine, carnitine, guarana, ginseng, ginkgo, minerals like magnesium or zinc – there is a myriad of natural nootropic substances that can benefit cognition.
Besides nutrients, vitamins, minerals, and neurotransmitter precursors (amino acids), there are also man-made synthetic nootropics. Those that are typically issued on prescription are called nootropic drugs, or smart drugs.
So cognitive enhancers are in use either as nootropics or smart drugs, depending on whether you prefer a natural or synthetic form.
Summary of cognitive enhancers types
In our introductory article about the history of nootropics, we learned that while all nootropics are cognitive enhancers, not all drugs that improve cognitive functions are nootropics.
This is the distinction:
Cognitive enhancer definition:
Cognition enhancer is pharmacological compound that enhances the mnemonic and cognitive function that can cross the blood-brain barrier.
Josef van der Staay (link)
Nootropics are substances that enhance learning and memory, with being safe and neuroprotective of the brain.
In the last 50 years, tremendous advances are made in the pharmacological characterization of substances with cognitive enhancing properties. So allow’s start with the three broad classifications of cognitive enhancers.
Those freely available, over-the-counter ingredients (e. g., methylxanthines such as caffeine, various botanicals, vitamins, and nutrients.)
synthetic cognitive enhancers
Prescription nootropic drugs and unregulated supplements (e. g., antidementia drugs, methylphenidate, racetams.)
Illicit smart drugs (E.G., illicit amphetamines such as Adderall)
In a narrower sense, we can classify six types of nootropics without a prescription. And a group of prescription nootropics that we commonly call ‘smart drugs’.
We can also classify (known) types of nootropics mechanisms of action by which they affect different systems and make effects on cognition.
Types of nootropics:
Natural Nootropics, Racetams, Choline, Ampakines, Vitamin B Derivatives, Peptides, and so-called “Smart Drugs” (prescription nootropics).
Nootropic mechanism of action:
Cholinergic, Dopaminergic, Serotonergic, Glutamate/Gabaergic, Metabolic, Neurohormone, Nerve growth promoter, Adaptogenic, Stimulant

guide to a different substances that affect
Nootropics mechanism of action
Nootropics can modulate a range of biological processes that aid in neurotransmission, intracellular signaling, and various molecular processes. Many nootropics can also improve the production of proteins that offer neuroprotection and promote brain health.
There are two kinds of effects that nootropics can participate in:
- altering or participating in neurotransmission
- participating in or influencing energy metabolism
altering the levels of hormones that affect the brain
protecting the brain from damage and dysfunction
ameliorating disorders that can affect cognitive functioning
Six brain pathways in neuroenhancement
Let’s take a look at six primary brain pathways and corresponding nootropic mechanisms of action.
1. Brain energy
Enhancing the metabolic activity of mitochondria, the powerhouses of brain cells (and other cells).
Helping to transport fatty acid material into brain cells, where they fuel mitochondria.
Increasing cerebral uptake of oxygen and nutrients, supplying the brain with “fuel” for energy production.
2. Neurotransmitters optimization
Supplying brain chemical precursors
Promoting neurotransmitter synthesis
Enhancing receptor sensitivity
Inhibiting neurotransmitter breakdown
3. Cerebral blood flow
Promoting nitric oxide activation and relaxation of blood vessels
Inhibiting homocysteine and oxidative damage on blood vessels
Making blood cells less “sticky” and thus less likely to clump
4. Brain waves
- Nootropics can raise Alpha brain waves that promote alert-yet-relaxed mind states for free-flowing creativity
Increasing the brain’s capacity to reduce free radicals and oxidative stress
Helping to fight the formation of irregular protein clusters (amyloids)
Clearing the brain tissue of neurotoxins
Protecting the brain against the negative effects of stress
6. Brain regeneration
Boosting natural brain-boosting growth factors, such as NGF
Providing raw neuronal building block materials, like choline
Maintaining brain cell membrane flexibility and plasticity
A few of these effects are achievable by the most effective stand-alone nootropics. But, typically only good stacking methods will provide all of these various mechanisms to work as a team.
Nootropics types by effects on neurotransmitters
Tyrosine, Choline, Phosphatidylcholine, Citicoline, Alpha-GPC, Vinpocetine, Noopept, Phosphatidylserine, Sulbutiamine, Aniracetam, Citicoline, Huperzine-A
Tryptophan, Vinpocetine, Noopept, Acetyl-L-Carnitine, Rhodiola rosea, Vitamin B6 as P-5-P, Vitamin B12
Vinpocetine, Noopept, ALCAR, Tyrosine, Phosphatidylserine, Sulbutiamine, L-DOPA, NADH, Vitamin B12
Tyrosine, L-Phenylalanine, NADH, Ephedra, DHA, P-5-P, Vitamin B12
Tyrosine, Taurine, SAMe, P-5-P (B6)
Inositol, Picamilon, GABA, Phenibut, P-5-P (B6)
Collection of different nootropics effects
Commercialized nootropics on market in the first place affect or mimic certain neurotransmitters. The main mechanisms influence the change in the concentration of brain chemicals that mediate the effects of nootropics on cognitive performance.
Cholinergic refers to a large number of nootropics or to any substance affecting the acetylcholine system. Acetylcholine is vital in muscular as well as cognitive function.
Types of nootropics with cholinergic activity:
- Positive Allosteric Modulators (Acetylcholine)
Positive allosteric modulators are substances that enhance the signal at a receptor. The racetam group (piracetam, aniracetam, oxiracetam, etc…) are positive allosteric modulators of the acetylcholine receptor. This is the main method of action for most types of racetams.
- Acetylcholine Precursors
Acetylcholine precursors are also considered to be types of cholinergic. This is because they directly or indirectly increase the amount of acetylcholine in the brain.
- Acetylcholinesterase Inhibitors
Acetylcholinesterase inhibitors influence the amount of acetylcholine by eliminating an enzyme known as acetylcholinesterase. They are potent and require a small dosage.
Choline, Alpha GPC, Citicoline, Centrophenoxine, Choline Bitartrate, Choline Citrate, Lecithin, DMAE, Phosphatidylcholine, Racetams, Huperzine A
Serotonergic substances are a class of compounds that relate to the natural chemical serotonin and boost its impacts on the body. Each substance that can do that works to either increase or subdues serotonin flow in order to achieve its impacts. Serotonin is the natural chemical that corrects nerve impulses, balances mood, as well as promotes general sensations of health.
Tryptophan, 5 HTP, Griffonia seed extract
Dopaminergic are a group of compounds that have an influence on dopamine levels in the brain. They work by handling the metabolic process as well as the synthesis of dopamine and are often straight precursors to dopamine. Dopamine is a neurotransmitter prevalent in cognitive functioning and in our psychological reward system. It plays a huge role in memory formation, mood, and focus/attention. Dopaminergic provides natural mental and physical energy while increasing performance, motivation, as well as focus.
Sulbutiamine, DL-Phenylalanine, Tyrosine, Phenylethylamine, L-Dopa, Mucuna Pruriens, Theanine, Rasagiline, Stablon, Deprenyl
Glutamate is the primary excitatory neurotransmitter, and the precursor for GABA, the brain’s main inhibitory neurotransmitter. A glutamatergic agent (or drug) is a chemical that directly modulates the system of excitatory amino acids in the body or brain.
Popular synthetic nootropics work by binding to glutamate receptors, primarily AMPA receptors, and NMDA receptors.
Piracetam was the first modern nootropic to act as a positive allosteric modulator of AMPA receptors. Racetams and especially Ampakines bind to the glutamatergic AMPA receptor and enhance its activity. By doing this they increase synaptic responses and enhance long-term potentiation (LTP).
Excessive glutamate in the brain is supposed to convert to inhibitory GABA automatically through an enzyme glutamic acid decarboxylase (GAD).
L-glutamine (main precursor for glutamate and GABA), N-Acetylcysteine (NAC), Piracetam, Aniracetam, Noopept, Sunifiram
GABAergic nootropics (Anxiolytics)
GABA (Gamma-Aminobutyric Acid) is a natural chemical that has an inhibitory effect on stress reactions in the nervous system. The class of GABAergic nootropics is able to complete this task by increasing ‘alpha wave’ production in the brain. GABAergic nootropics have a calming effect that is known to create a sense of well-being and relaxation in individuals. These nootropics are commonly used to promote correct sleep cycles, especially for people who have insomnia.
Vitamin B6, Zinc, PharmaGABA™, Kava Kava, Valerian Root, Magnesium, Taurine, American Ginseng, Theanine
Adaptogens or adaptogenic are compounds of plant and fungi origin that help maintain stabilization of physiological processes, so that brain cells can return to homeostasis. They do not serve only one function. Instead, they are able to adapt to what the body is facing and help alleviate or reduce symptoms. They promise to reduce stress, to improve attention and endurance in fatigue.
Ashwagandha, Ginseng, Eleuthero, Pine Pollen, Moringa, Rhodiola, Maca, Astragalus, Shilajit, Medicinal mushrooms
Cognitive Metabolic Enhancers boost the energy and metabolism of human brain cells. They improve vasodilatory blood circulation to the brain or improve the performance of cell membranes. By increasing the oxygen consumption of cells, they enhance metabolism and energy production. This supports the activity of different neurochemicals, such as dopamine, norepinephrine, epinephrine, and acetylcholine. Benefits can include mood improvement, wakefulness, and awareness, enhanced memory, and cognitive functions. This neuroprotective group enhances the health of neural cells by eliminating toxins as well as promoting the upkeep of brain cells.
Acetyl L-Carnitine, Alpha Lipoic Acid, Creatine, Pyritinol, Vincamine, Vinpocetine
Nerve growth promoters nootropics
Nerve growth factor (NGF) is a naturally occurring protein that consists of a group of molecules present in the brain for cognitive functioning. It is one of four proteins (among BDNF, NT-3, and NT-4) that contain neurotrophins. NGF takes care of survival and maintaining developed neurons while producing new ones. It contributes to the overall health of the brain. This class of substances includes some natural nootropics that are great free radical scavengers (antioxidants). Many cognitive problems associated with aging arise from oxidative damages. Nerve growth promoters may contribute to increased longevity and mental capacity protecting the neural cells from free radicals.
Lion’s Mane, PQQ, Quercetin, Zinc, Lithium, Royal Jelly, Rosemary, ALCAR, Huperzine A, Polygala tenuifolia, Co-Enzyme Q10, Idebenone
A neurohormone is any kind of hormone created and released by specialized neuroendocrine cells. They release them into the blood or to the cells of the body organ whose development it regulates. Neurohormones can also perform as neurotransmitters in the brain. In that case, they are processed in the hypothalamus and transferred for release through the pituitary gland. Dopamine, Epinephrine, Norepinephrine, and Oxytocin are a few well-known examples. These hormones have different specific effects. The benefit of mood support to bring back sleep/wake cycles, alertness, and concentration.
DHEA, Melatonin, Vasopressin, Desmopressin, Pregnenolone
Central nervous system stimulants are pharmacological compounds that induce short-lived changes to mental and physical energy levels, wakefulness, and alertness. Stimulants produce these effects by boosting or inhibiting various activities of the central and peripheral nervous systems. These effects can be achieved via the production of neurohormones like norepinephrine as well as dopamine, along with the interaction of specific receptor cells.
Modafinil, Adderall, Xanthines, Nicotine
Psychostimulants as Cognitive enhancers
The common prescription drugs, or ‘smart drugs’ as we like to call them, are types of CNS stimulants known as psychostimulants.
While smart drugs are not officially defined, references to this group generally include Provigil (modafinil), armodafinil, Adderall, and Ritalin (Methylphenidate).
Although they have been extensively described online as safe nootropics, we do not believe that, by original nootropic definition, they are.
Stimulants aren’t nootropics because they aren’t neuroprotective
Types of the stimulants
Amphetamines like Adderall is a schedule II controlled substance prescription drug for focus and energy. Invented by Big Pharma for ADHD patients with mild brain dysfunction. This kind of cognitive enhancer is not the best choice for otherwise healthy individuals without a history of medications. The problem is their potential for addiction and could have serious side effects if taken in the long run.
Modafinil is a wakefulness-promoting agent (eugeroic) prescribed against sleep attacks during the day or nightmares in the waking state. It increases focus and problem-solving ability. But it is not in the same class of drugs as Adderall and it is not a classic stimulant.
“Part of the way Modafinil works is by shifting the brain’s levels of norepinephrine, dopamine, serotonin, and other neurotransmitters; it’s not clear what effects these shifts may have on a person’s health in the long run.”
In 2011, while the movie “Limitless” came out, 650,000 people had Modafinil prescriptions. That changes in 2012 with almost 3x more prescriptions – 1,900,000.
Psychostimulants such as modafinil and methylphenidate (Ritalin) are popular among students around exam time. Army personnel that needs to remain awake for long missions. Athletes also have an affinity for modafinil, as well as entrepreneurs and Wall Street executives. Senior people worried about cognitive decline and college academics keen to keep their efficiency are also their supporters.
Adderall and Ritalin have been linked to insomnia, hallucinations, seizures, heart trouble, and sudden death in healthy individuals.
So why not look for the best amphetamine alternatives instead?
Over-the-counter nootropics refer to natural and synthetic supplements that can be purchased independently of a doctor.
Different types of natural dietary supplements are approved by the U.S. Food and Drug Administration (FDA) as being pure, accurately labeled, and of good quality.
When produced with a certification known as Good Manufacturing Practice (GMP), or other types of certificates, it follows a system that ensures the products are consistently produced and controlled by strict quality standards. Here are the categories of the most popular dietary supplements.
- Vitamins and minerals – multivitamins, vitamin D, calcium, vitamin C, and vitamin B/B complex.
- Specialty supplements – omega-3/fatty acids, supplements including fiber, probiotics, glucosamine/chondroitin, and CoQ10.
- Sports nutrition and weight management – protein supplement, energy drinks, and gels, Garcinia Cambogia, green coffee, and hydration drinks and gels.
- Herbal/botanical nootropic supplements – botanicals, green tea, garlic, cranberry, echinacea, and ginseng.
Establishing natural nootropics
Nootropic brain herbs are proven for cognitive function. They are less addictive and much safer than synthetic drugs. Herbs naturally supply a myriad of active brain-boosting compounds. The products are made from whole plants, plant parts, or plant extracts. Also from fungi, which have one of the longest histories in traditional medicine and health practices.

The most popular herbal nootropics:
- Bacopa Monnieri
- Rhodiola Rosea
- Lion’s mane mushroom
- L-theanine (found in green tea)
- Huperzine A
- Mucuna pruriens (L-dopa)
- Curcumin (found in turmeric)

Status of synthetic nootropics
Federal Drug Administration (FDA) looks if the ingredient fills the definition of a dietary supplement by their DSHEA criterion. One of the popular ingredients among nootropic enthusiasts is Piracetam. By late 2003 its status was to ”not fit the description of a dietary ingredient.” FDA sent a warning letter about it in 2010 and named Piracetam a ”New drug”.
The status of synthetic nootropics could change in the years to come. In many countries around the world, they can still only be taken with a prescription. In the US, they are supplements or banned substances.
It’s a gray area, and the supplement companies still selling them on Amazon and eBay, but sometimes as “not for human consumption”.
In its renewed attempt to fulfill its 2010 warning, the FDA is trying to withdraw Piracetam from all dietary supplements containing this substance (August 2020).
“Its pretty much impossible to find Piracetam in the EU now as well. You can however still buy some highly experimental, potentially dangerous compounds without issue. Meanwhile the quite well researched Piracetam is off the market. It’s a strange time we live in.”
– Reddit Nootropics 2020
Why is that so a big deal when synthetic nootropics are by original definition non-toxic?
Well, synthetic nootropics are invasive and skipping a few steps in the natural metabolism of primary chemicals like dopamine, serotonin, acetylcholine, GABA. That’s why they are effective in the short term with faster results than natural nootropics. Although non-toxic, they can cause side effects in the long run if taken unreasonably. Extensive human clinical trials are also required.
Best synthetic nootropics to use with caution
Racetams are neuroprotective agents that can speed out the rate at which brain cells reproduce and slow down the rate at which they deteriorate. Many beginners choose the original nootropic Piracetam to get started with the benefits of better memory. For a particular demand like having more energy or creativity boost, they look at its derivatives. Other top racetams are Aniracetam, Oxiracetam, Pramiracetam, and Phenylpiracetam.
Adrafinil is a pro-drug and a replacement for banned Modafinil. It means that its supplementation increases the concentration of Modafinil in the body. Adrafinil is similar to Modafinil as it has a strong effect on day-time alertness, motivation, mood, and energy levels. It is recommended for clients with sleep disorders like narcolepsy or sleep apnea. While stimulating, it does not generate side effects like other stimulants. In the US, it is currently legal and prescription-free. It is allowed for purchase from British residents, but only for personal use.
Noopept was created in the mid-1970s by Russian scientists and earned the track record of being a thousand times more powerful than Piracetam. Its action of crossing the blood-brain barrier implies that you can take fewer doses and still attain great results. Noopept stimulates both AMPA and NMDA receptors, control glutamate and acetylcholine levels. This makes it in a close relationship with the racetams and ampakines. In Russia, Noopept is sold without a prescription. It was patented with the same original formula in the US and is sold as a dietary supplement.
Phenibut is a GABA (gamma-aminobutyric acid) analog, working as a GABA receptor agonist in the brain. It stimulates neuroreceptors like GABA and dopamine, reducing stress and pain throughout the body. This nootropic has a strong effect and is best used only occasionally and even then with longer breaks. Some individuals do not experience withdrawals from this substance just like there are people who are complete non-responders to it. Phenibut is legally bought and owned, but illegally sold or produced from the standpoint of the law.

7 types of nootropics & smart drugs
I. Natural nootropics
Natural nootropics are safe types of nootropics but somewhat less potent than synthetic nootropics. They have diverse cognitive effects through a wide range of mechanisms of action. While some will improve the blood flow in brains, others may help restore nerve damage, or back to balance neurotransmitters. What’s convenient, they all combine well with each other making it possible to stack them for powerful natural enhancement.
Nootropic nutrients are any natural compounds that the human brain can use to repair cell damage and to promote heightened states of cognition. While supporting the growth and repair of neural tissues, they can also stimulate the production of neurochemicals to manage various physical reactions.
Nootropics nutrients can regulate metabolism. They can generate energy in the short term, as well as provide long-term protection for various systems. People take them for organ support, immunity, to boost cellular health, and to help support healthy stress levels. According to research, they can create an environment of neuroplasticity for enduring mental health.
Omega-3, Magnesium, Krill Oil, Fish Oil, Phosphatidylserine, SAMe, Taurine, Carnosine, Iodine, L-Glutamine, Lysine, Phenylalanine, Uridine
Plant-derived nootropics are the primal group of cognitive enhancers. There is an extensive list of herbal nootropics, known to man for millennia. As a rule, they are less effective as stand-alone supplements than some of their synthetic cousins. But if they are produced in the right form as standardized extracts, then they are the best. Herbal nootropics tend to be most effective when stacked into a synergy mix. The stacking between ingredients is where they shine. Fungi are also a part of this group, and they are the world of themselves. Medicinal mushrooms are some of the most powerful natural nootropics.
Bacopa Monnieri, Rhodiola Rosea, Ashwagandha, Ginkgo Biloba, Panax Ginseng, Lion’s Mane, Cordyceps, Red Reishi, and other medicinal mushrooms
Xanthines are a class of natural energizers derived from xanthine, a purine base found in the cells of nearly all organic life. These alkaloids show excitatory or stimulant effects in the central and sympathetic nervous systems. Xanthines restrict the effects of adenosine, a natural chemical that triggers sensations of drowsiness. Xanthines can elevate the heart rate and boost blood circulation. They can raise the activity of the breathing system and act as bronchodilators. Xanthines are taken for mild, short-term energy boosts. They can lift mood, give mental focus, and create a sense of alertness. Some of these substances are habit-forming and can generate strong withdrawal effects.
Caffeine, Green tea, Theobromine
Racetams are the family of original laboratory invented nootropic compound Piracetam. This is a primal nootropic with which racetams share the same 2-pyrrolidone nucleus structure. This structure is a derivative of gamma-aminobutyric acid (GABA). Racetams stimulate acetylcholine that is active in the prefrontal cortex and glutamate receptors.
There are about twenty different types of racetams. They boost cognitive functions by promoting acetylcholine receptors. Also, racetams speed up the rate at which the brain cells are regrown and reduce the rate at which they deteriorate and die. Some racetams stimulate glutamate receptors. This task is making them hybrids that additionally belong to the Ampakine type of nootropics.
Piracetam and Noopept (to some extent also a racetam) neutralize cognitive decline. Additionally, Aniracetam and Noopept are great options for reducing stress symptoms. They can help improve your mood.
Some authorities say that racetams are not supplements, but unapproved drugs promoted online. But anecdotal experience teaches us that with responsible use racetams can be as safe as they are effective nootropics.
Learn more in our guide to the best 9 racetams nootropics.
Aniracetam, Oxiracetam, Pramiracetam, Phenylpiracetam
III. Choline and acetylcholine intermediates
Choline is one of the most important types of nootropics for brain health, memory, and mental clarity. It is a precursor for the production of acetylcholine. This neurotransmitter facilitates communication between neurons. Choline is also a precursor to phosphatidylcholine, which is a key component of cellular membranes. The best sources of choline are alpha-GPC and citicoline. They produce higher levels of acetylcholine in the brain.
Choline donors work in synergy with other nootropics, so they are an important part of every modern nootropic stack. For racetams users, due to raised acetylcholine intake, it is better to replenish stacks with more choline to meet the needs. Choline donors are safe to use and have less chance of creating side effects. There are many sources of choline/acetylcholine donors. Some will be more reliable compared to others.
Alpha GPC, Citicoline, DMAE, Choline Bitartrate, Centrophenoxine
Acetylcholinesterase inhibitors are a class of compounds that limit the activity of acetylcholinesterase enzyme. This enzyme reduces the amount of acetylcholine in the brain. Acetylcholine facilitates comprehension, logical, and verbal reasoning, memory formation. It also raises sensitivity to stimuli and promotes the development of neural frameworks. Thus, acetylcholinesterase inhibitors increase the availability of this natural chemical. They have long-term neuroprotective benefits too. As well as the immediate gains in memory and learning features.
Huperzine A, Galantamine
IV. B-vitamin-derived nootropics
B vitamins are vital for brain health and normal function of the nervous system. While we still don’t know what cognitive functions B vitamins can improve and how they are crucial for many processes. Vitamins B6, B9, and B12 are backed by the most research because of their ability to regulate homocysteine levels.
Vitamin B6 helps the brain circulation and neurotransmitters. It is a coenzyme for the synthesis of dopamine, epinephrine, GABA, melatonin, norepinephrine, and serotonin.
Vitamin B9 (folate) is important for the optimized brain. As a nootropic, folate takes part in gene expression, amino-acid synthesis, and myelin synthesis. It is also required for the synthesis of dopamine, epinephrine, norepinephrine, and serotonin.
Vitamin B-12 helps form nerve-protecting myelin and maintains brain tissue. It is a cofactor in the synthesis of dopamine, GABA, norepinephrine, and serotonin. It affects alertness, cognition, memory, and mood.
Modified vitamin B derivatives are stronger than natural vitamin B. They can cross the blood-brain barrier, providing a key component in converting glucose into energy. Sulbutiamine is a derivative of vitamin B1 developed by the Japanese to combat fatigue. Picamilion combines vitamin B3 (Niacin) with GABA. Pyritinol is created from vitamin B6.
Ampakines are new compounds in the area of brain research and have not yet been thoroughly tested. These compounds seem to be 1000 times stronger than piracetam. They induce stronger effects on glutamate receptors than racetams.
For comparison, Piracetam and Aniracetam are weak stimulants of AMPA receptors. While ampakines are extra-potent stimulants of glutamate receptors.
Ampakines function by antagonizing the AMPA and NMDA receptors. Both receptors depend on the natural chemical glutamate to work. This causes an increase in glutamate levels in the brain. Glutamate is a neurotransmitter that has an essential duty in synaptic plasticity. It is vital to the process of learning and memory. By increasing the glutamate and acetylcholine levels in the brain, Ampakines raise attention span and alertness.
Ampakines have stimulant-like effects without the adverse side-effects reported in traditional stimulants like caffeine and Ritalin. This type of nootropics doesn’t create undesirable effects like uneasiness, sleeplessness, and anxiousness. They are researched as a potential relief for sufferers of psychiatric illnesses. But, likely are not without danger to teens, adolescents, and youngsters.
VI. Peptide nootropics
Russia is the homeland of peptides, an intriguing compound that appears to be constantly evolving. The hallmark of this category is Noopept. It is one of the most preferred and strongest synthetic compounds in the legal marketplace. Noopept is derived from racetams and made to be highly bioavailable. This class can cross the blood-brain barrier, but it will need different routes of consumption – through the mouth, nose, and injections.
A low dose of peptides will have the same effects as racetams. Also, they work better to heighten the release of glutamate.
Peptides activate brain-derived neurotrophic factor (BDNF), an important protein that plays a part in neurogenesis. Also, peptides activate serotonergic and dopaminergic systems.
Noopept promotes the release of the Nerve growth factor, a protein essential for the growth and maintenance of neurons. The influence on memory, brain performance, and motivation are favorable. Noopept boosts mental state due to the enhanced oxygen flow to the brain, as well as maintenance of cells. Many individuals report similar results as with racetams.
The major disadvantage in taking other peptide nootropics remains in their route of administration. Semax should be taken nasally to have effects. Cerebrolysin is most likely one of the most reliable peptides, only it must be injected.
VII. Smart drugs
In addition to the aforementioned psychostimulants Adderall and Modafinil, other types of stimulants fit the category of a smart drug. In fact, according to the classical meaning, smart drugs are not nootropics. It is rather a border term between the nootropics and drugs. These sorts of drugs can be of some benefit for signs and symptoms associated with cognitive conditions. They offer an effective boost to normal reasoning, learning, memory, and focus. But, because long-lasting usage triggers several side effects, they are not the best selection for already healthy individuals.
Nootropic drugs are medicinal compounds that can enhance cognitive functions by connecting with natural brain chemistry. They originate from natural resources or consist of synthetic variations of those sources developed in a lab. Nootropic drugs work by creating, potentiating, or limiting the amounts of natural neurotransmitters, enzymes, and hormones. They can have either stimulating or relaxing effects. Nootropic drugs also elevate or decrease blood pressure as required.
This type of cognitive enhancer interacts with the growth, health, repair, and communication of neurons and synapses. Through this activity, they can enhance memory, lift mood, and heighten learning capabilities. These drugs are being researched in mental health to restore balance and combat symptoms of cognitive disorders such as ADHD or Alzheimer’s disease. Nootropic drugs promote mental efficacy and social confidence with applications for college students, business owners, and senior citizens. On the other side, they are not over-the-counter nootropics in many countries.
Cerebrolysin, Hydergine, Nicergoline, Propranolol, Semax, Selank
Stimulants are pharmacological compounds that induce short-lived changes to mental and physical conditions. That’s usually related to the energy levels. Stimulants produce these effects by boosting or inhibiting various activities of the central and peripheral nervous systems. These effects can be achieved via the production of neurohormones like norepinephrine as well as dopamine, along with the interaction of specific receptor cells.
Stimulant balance focus and alertness, higher motivation, sexual stimulation, athletic endurance, and reduced appetite. Stimulants can also be powerful mood enhancers. Prescribed by healthcare professionals, they help aid in the treatment of various cognitive disorders, such as OCD and ADHD. Under the technical definition for nootropics, stimulants are particularly illicit because of the frequency of associated negative effects.
Nicotine, Ephedrine, Geranamine, Yohimbine HCL, Octopamine

There are various types of nootropics and their categorization according to mechanisms of action, effects, or market status. But the confusion is greatly alleviated by the fact that nootropics from different groups usually get along well.
How to combine or stack nootropics properly is an art in itself.
How to live the right lifestyle for biohacking, even more.
No matter what your intentions are, talk to a medical specialist first.
Stay close with the family of natural nootropics. I found credibility in taking natural pre-made formulations from respected sources like Mind Lab Pro and Performance Lab. Both companies combine branded natural nootropic supplements together to touch all aspects of cognitive function in the right way.
You can also supplement with simple but effective nootropics – vitamins, minerals, amino acids, herbs, and superfoods. Synthetic compounds like racetams for your short-term and long-term goals.
Now that you have learned about nootropics types and effects, read about stacking nootropics.
