The human brain is a mystery. But it’s increasingly clear that supporting the brain is key for overall health — while optimizing the brain may be the secret to getting the most out of life itself.
Nootropics may help. These natural or synthetic substances — also known as smart drugs, brain-boosters and memory-enhancers — are taken to help with recall, learning, mental energy, focus, mood and many other aspects of brain health and function.
As interest in brain biohacking has skyrocketed in recent years, so has interest in nootropics — at least according to Google Trends:
The nootropic category is expanding, too: Encompassing a broader array of brain-boosting compounds with more diverse bio-activities. As brain research intensifies, even more nootropics are being identified, and more brain benefits discovered, with each passing year.
In other words, the nootropic landscape is more complex than ever before.
This guide was developed to simplify nootropics with a brief, practical introduction on how they might work, which ones show the most potential, and how to best take them for brain-boosting results.
Nootropic Criterianutrients are considered nootropics? Here’s where things get tricky: There’s little agreement on what truly constitutes a nootropic nutrient.
Even Russian nootropic pioneers Corneliu Giurgia and Vladimir Skondia had conflicting ideas about what defined a nootropic. A few of the paraphrased areas they seemed to agree upon:
By the strictest definition, only a handful of nootropic nutrients exist.
However, most have a more flexible view of the term, and consider dozens of different compounds to be nootropic in nature — including many that are for brain health, but not mental performance.
Types of Nootropics
Types of Nootropicst popular nootropics overall are herbal, including Bacopa, Rhodiola and Ginkgo biloba. When herbal nootropics are “standardized,” their active ingredients — such as bacosides in Bacopa — are lab-isolated and presented in exact levels. Concentrated herbal extracts similarly enhance the potency of raw herbs, but are not as precise. Herbal nootropics are highly versatile, supporting brain function and mental performance in many ways.
Adaptogens are a
Adaptogensl nootropics that we separate for their unique anti-stress mechanisms of action. Adaptogens target the body’s endocrine system, where they neutralize stress hormones and stress responses. This helps the brain to “adapt” to all stressors; emotional, physical, toxic, environmental, etc. Nootropic adaptogens were used by Russian Olympic athletes and cosmonauts to enhance physical performance and maintain focus, clarity and sound reasoning under the most stressful of conditions.
Synthetic Supplementscomplicated, in terms of nootropic legality. In some cases, a nootropic compound that is found in plants may be synthesized in a laboratory, yielding a synthetic analogue of the original botanical. Two prominent examples are vinpocetine and huperzine-A. Because they walk the fine line between synthetic and botanical, in some countries they are regulated as drugs and you need a prescription to take them.
Synthetic Drugswith over-the-counter supplements, they technically also include pharmaceutical drugs that have been prescribed by a doctor. Adderall and other pharmaceuticals are increasingly prescribed to help both children and adults who have attention problems. Nootropic drugs have an advantage of clinical proof in premarket testing, but also have notable disadvantages of side effects and addiction concerns.
This class of nootropics o
Racetamsia in the 1960s, and now includes no less than 19 different brain-boosting compounds that all share a similar molecular structure. Piracetam may be the most well-known racetam nootropic. Although the United States FDA is not a fan of racetams, these compounds have for the most part been shown to be safe, well-tolerated and beneficial. Developed to both boost mental performance and assist with age-related cognitive decline, racetams appear to have far-reaching benefits for overall healthy brain function.
Phospholipids are a sp
Phospholipidsat are associated with nootropic benefits and have important roles in brain cell formation. Some phospholipids taken for brain health include phosphatidylcholine, phosphatidylserine, Citicoline, Alpha-GPC, and DHA. Sourced from egg yolks, soy, sunflower, cold-water fish, and animal organs, phospholipids seem best suited for helping to build and repair brain cells. Some Play an especially important brain health role in supporting fluid, peak-performing brain cell membranes.
How do Nootropics Work?
How do Nootropics Work?how nootropics work. But research has identified several different bio-activities by which nootropics might enhance brainpower.
The best nootropic compounds may promote several of these bio-activities at once. By combining nootropics into stacks, some supplements can effectively boost many aspects of cognition.
Research has suggested that nootropic nutrients appear to:
Enhance Brain Energy
Enhance Brain Energy/uploads/2016/04/Brain-Energy.jpg">The human brain is an energy-intensive organ, consuming about 20% of the body’s power supply.
When the brain doesn’t get the oxygen, circulation and nourishment it needs, its energy levels may decline — leading to brain fog, slow thinking and mental fatigue.
Nootropics can help brain energy metabolism by:
- Delivering more oxygen to brain cells that’s burned for energy
- Improving mitochondria efficiency and structural integrity
- Funneling fatty acids into brain cells to be burned as fuel
Better brain energy appears to translate to diverse mental performance enhancements, including improved brain energy, attention, processing speed and focus.
Nootropics for Brain Energy
- Citicoline – Shown in human research to boost brain energy metabolism by 14%
- PQQ – Emerging antioxidant nootropic with unique mitochondria-optimizing activity
- NADH – Sparks brain ATP energy; shown to help Chronic Fatigue Syndrome brain fog
Increase Brain Chemicals
Brain chemicals, also called neurotransmitters, are substances that carry information from one neuron to the next. Neurotransmitters serve many purposes in brain & body, including regulating all forms of thinking and all types of mindsets.
Many nootropics can influence neurotransmitters in many ways, making this one of the most evidence-backed areas of nootropics’ cognitive bio-activity. Nootropics help to improve neurotransmitter status by:
- Supplying building blocks for synthesizing brain chemicals
- Sending signals that trigger the release of brain chemicals
- Protecting and sustaining brain chemicals in the bloodstream
|Neurotransmitter||Mental performance||Associated Nootropics|
|Acetylcholine (ACh)||Memory, cognition||Aniracetam, Huperzine-A, Citicoline|
|Dopamine (DA)||Mood and motivation||L-Theanine, L-DOPA, NADH|
|Serotonin (5HT)||Relaxation, feeling good||5-HTP, Vitamin B12, Tryptophan|
|Norepinephrine (NE)||Attention & intense focus||Vitamin B6 (as P5P), L-Tyrosine|
Targeted nootropic supplementation for neurotransmitters can affect virtually all aspects of brain performance. The right ones in combination can help mood, mental clarity, memory formation, motivation and more. Neurotransmitters are also closely tied to long-range brain health.
Some other nootropics for brain chemicals:
- Bacopa monnieri – better when standardized to active bacosides
- Acetyl-L-Carnitine – Needed to synthesize acetylcholine
- B-Complex – Especially B6 as P-5-P and B12 as methylcobalamin
Boost blood flow to the brain
Boost blood flow to the brainrain-Circulation.jpg">Peak circulation promotes peak brainpower, and is a hallmark bio-activity of some of the best nootropics. Healthy cerebral circulation helps flush the brain of toxins while supplying energizing oxygen and brain nourishment.
Impaired cerebral circulation, on the other hand, is considered a major brain health risk factor, implicated in everything from strokes to age-related cognitive decline, especially as vascular dementia.
Nootropics boost bloodflow to the brain in several ways:
- Signal for Nitric Oxide to open and relax blood vessels
- Protect cerebral blood vessels from homocysteine & oxidation
- Support flexible, supple brain blood veins, arteries & capillaries
Brain circulation ties to direct mental performance benefits, especially for memory, whole also supporting long-range healthy brain aging.
Brain circulation-boosting nootropics include:
- Ginkgo biloba – Ancient tree extract is legendary for boosting brain circulation
- Vinpocetine – Shown in clinical trials to boost brain circulation several times over
- Citicoline – One animal study showed it boosted brain circulation by 35%
Regenerate Brain Cells
Regenerate Brain CellsRegeneration.jpg">The brain is capable of regenerating brain cells, a process known as neurogenesis. Some nootropics provide the nutritional building blocks, cell energy and nerve stimulation that are needed for robust neurogenesis. These same nootropics help with brain cell maintenance, cell membrane repair, and brain plasticity.
Structural support of brain cells is mostly linked to better long-term brain health and slower, milder age-related cognitive decline, and some researchers have suggested regenerative nootropics may be useful in “reversing age-related changes in the brain.”
Some Nootropics for brain regeneration include:
- Lion’s Mane – Boosts brain-building Nerve-Growth Factor (NGF)
- Phosphatidylcholine (PC) – Raw material for brain regeneration & repair
- Phosphatidylserine (PS) – Best nootropic for maintaining brain cell membranes
“Tune” Brain Waves
“Tune” Brain Wavestropics.jpg">Have you ever seen an EEG (electroencephalogram) machine with dozens of electrodes connected to someone’s head? Among other uses, EEG testing measures Brain Waves (neural oscillations if you want to get fancy).
Different brain wave frequencies–Alpha, Beta, Delta and Theta–reflect different mental states. In theory, by modulating these frequencies, nootropics can “fine-tune” the brain for specific mindsets.
How do nootropics help brain waves? Evidence suggests they might increase the Alpha frequency, promoting a feeling described as “wakeful relaxation.” This state is perfect for calm & clear thinking, creativity and peak work productivity.
Brain wave nootropics include:
- L-Theanine – Shown to boost Alpha waves without inducing drowsiness
- Oatstraw – Shown to alter EEG readings and promote cognitive performance
Strengthen brain’s resistance to stress
A stressed-out brain can make bad decisions, be absent-minded, and easily take a nosedive into mental fatigue and negative moods.
A special class of herbs known as adaptogens can unlock peak mental performance by strengthening the brain’s resistance to stress–especially in high-intensity, pressure-filled, and highly competitive scenarios. Other nootropics help to reverse stress’s brain chemical impact on the brain.
Stress-resistance nootropics include:
- Rhodiola rosea – Root adaptogen herb for mind-body strength
- Bacopa – Versatile adaptogen with broad nootropic activity
- L-Tyrosine – Replenishes neurotransmitters depleted by stress

Free radicals — unstable compounds that smash and damage brain cells — create oxidative stress that causes brain degeneration, especially Alzheimer’s and dementia. Irregular protein clusters called amyloids are another brain health risk factor.
How do nootropics protect the brain? Usually they are antioxidants, which can neutralize free radicals. Some other nootropics can block the formation and slow the progression of amyloid proteins.
These nootropics are not known for boosting mental performance until you get older, at which point (in theory) a well-protected brain will better retain its youthful performance and sharp memory.
Neuroprotective nootropics include:
- Pterostilbene – Blueberry-derived antioxidant that fights brain aging
- Curcumin – Turmeric’s active anti-amyloid & antioxidant compound
- CoQ10/Ubiquinol – Unique “energizing antioxidant” duo for brain longevity
The above nootropic bio-activities may combine to affect thinking in many

Most nootropics in this category are associated with protecting memory against age-related brain degeneration — which in turn may promote better quality of life in elderly populations, especially those who already have some degree of dementia.
Focus, Concentration & Attention
According to the Focus, Concentration & Attentionolamine Hypothesis, neurotransmitter imbalance causes attention problems. Nootropics that target norepinephrine, epinephrine, and dopamine may help people maintain attention, focus and concentration. Phospholipid, antioxidant and botanical brain nutrients have also shown potential for helping with concentration, “focused attention” and attentional performance.

Pharmaceutical drugs taken without a prescription also cross the line into illegal territory. Sometimes for nootropics formula is legal, but the language used to market it is not — claiming that a nootropic prevents a brain disease, for example, would be a violation. Nootropics may also be considered banned substances, adding another layer of illegality.
Legality of nootropics is a complicated subject, but overall, the vast majority of nootropics presented a nutritional supplement are safe and legal to use. More on nootropic legality
Do Nootropics Have Side Effects?
By strict definition, in order to be “nootropic” a compound must be safe and free of side
Do Nootropics Have Side Effects?#8212; although some nootropics may come with side effects, depending on individual tolerance.
Caffeine, which is used in some nootropic formulas (though we do not consider it a true nootropic), boosts alertness but may have side effects for irritability, nervousness, jitters and sleep disruptions. Pharmaceutical nootropics may have a much longer list of side effects, but that’s also because they have been extensively studied in pre-market human clinical trials to demonstrate safety.
For many nootropics, there is simply too little clinical research to definitively know whether there are associated side effects or not. But some are backed by a long history of safety and tolerability that may serve as anecdotale evidence. More on Nootropic Side Effects
What is Nootropic Stacking?
What is Nootropic Stacking?s://supplementsinreview.com/wp-content/uploads/2016/05/nootropic-stack-153x300.jpg" alt="Tablets isolated on white background" width="153" height="300" srcset="https://supplementsinreview.com/wp-content/uploads/2016/05/nootropic-stack-153x300.jpg 153w, https://supplementsinreview.com/wp-content/uploads/2016/05/nootropic-stack-524x1024.jpg 524w, https://supplementsinreview.com/wp-content/uploads/2016/05/nootropic-stack.jpg 695w" sizes="(max-width: 153px) 100vw, 153px"/>Stacking refers to the process of combining different nootropics into a formula that has greater brain-boosting effects than the sum of its parts. Some stacking strategies for nootropic compounds:
- Combining nootropics that address the same aspect of mental performance via separate brain pathways, which may have a multiplying effect.
- Combining synergistic nootropics. Some compounds amplify & enhance each other’s brain-boosting activity
- Combining complementary nootropics. Separate from synergy, some nootropic nutrients seem to complete others and work well together.
The brain’s complexity — as well as the sheer number of different ways the entire spectrum of nootropics can enhance the brain — have made the nootropic stacking a popular strategy for boosting brainpower.
Stacking is like a hobby for some nootropic users. By purchasing many powder-form nootropics and filling their own capsules, these advanced brain bio-hackers can customize any stack they want, try limitless nootropic combinations, and use trial and error to figure out what works best for them.
For those who don’t want to deal with measuring powders and filling capsules, there are many pre-made nootropic stacks on the market. These supplements don’t allow customization — some don’t even show dosages — but they offer advantages in ease-of-use, and in some cases, price.
Despite the appeal of stacking, single-ingredient nootropic supplements are still highly useful. Some brain bio-hackers will start with one premade nootropic stack and then build upon it — adding single-nutrient “boosters” in the areas where they want extra brainpower.
