My Ultimate Guide to The Best Nootropics - How to Improve Focus, Memory And Learning

By Richard Davidson, October 22 2025
What Are Nootropics?
Nootropics are compounds known to help improve different aspects of human cognition or brain function, for example increasing the ability to focus, recall information or think more clearly. There are many nootropics that have been proven to be effective in improving cognitive performance [1],[2], many of which we’ll explain in greater detail below.It’s worth noting that there are many different categories of nootropics, including some vitamins, herbal extracts, amino acids, choline donors, synthetic compounds and some pharmaceuticals [5][6].
Key Points
- Nootropics can help people improve their focus, better retain learned information and help increase focus and motivation [1].
- Nootropics include plant-derived ingredient, vitamins, dietary aids, synthetic molecules and some pharmaceutical substances [2].
- Proven nootropic ingredients include Citicoline, Bacopa Monnieri, Lion’s Mane, L-Theanine, Rhodiola Extract and Ginkgo Biloba. These are some of the most widely used nootropics, in large part due to extensive clinical research into their effectiveness in promoting different aspects of cognitive performance and brain function [5][9].
- Different nootropics work in different ways. For example, by altering neurotransmitters, encouraging cerebral blood flow, or assisting cellular energy pathways [10][11].
- To get the most from nootropics following a healthy lifestyle has been shown to help. Particularly getting quality rest, eating a healthy and varied diet and taking regular exercise. [12][13].
- All-in-one nootropic supplements like ThinkEase are also available which can help in combining the right ingredients at safe and effective levels [14].
How Do Nootropics Work?
Dr. Corneliu Giurgea same up with a generally accepted definition of nootropics in the 1970s. In essence nootropic substances can be defined as compounds known to provide cognitive support with minimal adverse outcomes [15]. Meeting that definition often involves positively improving or assisting the brain’s chemistry or physiology in some ways. Some nootropics promote acetylcholine, a neurotransmitter critical to learning and memory [10]. Others address dopamine or serotonin, influence blood flow, or assist mitochondria in neurons, potentially benefiting attention or alertness [16][17]. Some are linked to stress responses, possibly aiding resilience during challenging tasks [9][18].
Nootropics can be categorized into several distinct types: Natural compounds, like Bacopa Monnieri and Lion’s Mane mushroom; nutritional aids such as B vitamins or omega-3; synthetic non-prescription compounds such as L-Theanine or caffeine and finally, prescription stimulants for conditions like ADHD [2][19].
How To Get Started With Nootropics
Before deciding which nootropics are right for you, it’s important to first define exactly what your personal objectives are. For example, students might prioritise improved learning and recall abilities. A professional struggling to maintain steady focus might prioritize increasing alertness without the jittery sensations that are often associated with stimulants such as caffeine. Some people may prioritize improving mental stamina during stressful periods, while those concerned about aging effects might prioritize reduced brain fog and neuro protection. Once your priorities are clear, it’s a simpler process to finding the risk nootropic or combination of nootropics for your needs.
The Best Nootropics And What They Do
There are many different nootropics, but these are the most well researched, proven to have positive cognitive benefits and which are also readily available.
Vitamin B6 (Pyridoxine):
Vitamin B6 supports in the production of neurotransmitters such as serotonin, dopamine and GABA, which in turn help influence mood balance, attention and mental clarity [20]. Research suggests that B6 levels support normal brain function and may assist memory-related tasks. B6 deficiency can negatively impact mental clarity. Some studies observe that B6, when combined with other micronutrients, might modestly improve cognitive test results. Its availability in various foods and supplements, combined with a low risk profile make it a popular nootropic.
Vitamin B9 (Folate):
Folate supports DNA and RNA synthesis, which are essential for healthy neuronal development and maintenance [21]. Low folate levels are associated with low mood and cognitive decline. Folate may help preserve cognitive performance and assist in normalizing homocysteine levels (which when elevated can impact brain health). Research also indicates that stable folate levels have improved memory test results in older adults. Folate can be combined with other B vitamins for better results.
Vitamin B12 (Cobalamin):
Vitamin B12 is required for myelin formation, which insulates nerve fibers. In turn this supports efficient communication between neurons [19][24]. Studies link B12 deficiency with memory problems and a general decline in cognitive function. Improving B12 levels can improve concentration and mood. Whilst not a stimulant, maintaining adequate B12 can help preserve long-term brain health.
Acetyl L-Carnitine (ALCAR):
Acetyl L-Carnitine helps shuttle fatty acids into mitochondria, potentially aiding cellular energy production in brain cells [16]. Some human trials have linked it to better mental energy and improvements in attention. It can also help improve conditions linked to cognitive slowdown. Though effects can be subtle, several studies suggest that ALCAR might benefit elderly populations experiencing mild memory difficulties. It may also support mood regulation. While not as widely known as some nootropics, its cognitive benefits are well documented.
Lion’s Mane (Hericium erinaceus):
Lion’s Mane mushroom contains compounds believed to promote nerve growth factor (NGF) synthesis, which contributes to maintaining healthy neurons and possibly forming new connections [9][10]. Research suggests this can improve memory, attention and mood. Some clinical trials have found that individuals taking Lion’s Mane extract performed better on certain cognitive tasks compared to placebo groups. Though more large-scale studies are needed, its historical use in some traditional cultures alongside more recent clinical research have led to it being widely recognized for its cognitive benefits.
Bacopa Monnieri:
This herb, long utilized in Ayurvedic medicine, is one of the most extensively studied natural nootropics [5][20]. Its bioactive compounds may improve synaptic communication and exert antioxidant effects in the brain. Numerous trials show Bacopa can improve memory recall, processing speed and reduce anxiety symptoms in healthy adults. Its effects often require several weeks of continuous use to appear. While not a stimulant, Bacopa can gradually support students or professionals interested in improving memory and recall.
N-Acetyl L-Tyrosine (NALT):
NALT provides a more soluble form of the amino acid tyrosine, a precursor to dopamine and norepinephrine [18][22]. Under conditions of stress or sleep deprivation, NALT supplementation may help maintain mental performance by ensuring that the brain has the raw materials needed to produce neurotransmitters. Evidence suggests NALT may improve focus, reaction time and working memory, even under demanding conditions. While not a cure-all, it may assist individuals who face demanding cognitive workloads.
Citicoline (CDP-Choline):
Citicoline supports the production of phospholipids in cell membranes, which assist neuronal communication [6][21]. Studies indicate citicoline supplementation can improve attention, mental energy and memory in both younger and older adults. It may help with verbal learning tasks and increase the availability of acetylcholine. Some evidence suggests it can aid in recovery from certain brain injuries and help maintain mental sharpness under normal conditions. As a choline donor, it is considered safe and well-tolerated.
L-Theanine:
Found in tea leaves, L-Theanine pairs well with caffeine (in supplement form or through beverages such as coffee) [8][22]. It may promote a state of relaxed alertness by modulating alpha brain waves and increasing levels of calming neurotransmitters. Research shows it can reduce stress responses and improve attention without causing sedation. When combined with moderate caffeine doses, L-Theanine can smooth out the jittery feelings that caffeine can cause, whilst retaining benefits like faster reaction times or greater mental clarity.
Rhodiola Extract (Rhodiola rosea):
This botanical is an adaptogen. Rhodiola has been studied for its ability to reduce feelings of fatigue and maintain mental performance in challenging situations [9][11]. Some trials show that Rhodiola can support attention, decrease mental exhaustion, and improve the sense of well-being. It may influence neurotransmitter systems and offer mild antioxidant properties. Whilst it’s a proven memory enhancer, Rhodiola’s main appeal lies in helping individuals stay mentally balanced during times of stress or heavy workloads.
Ginkgo Biloba:
Ginkgo leaves contain flavonoids and terpenoids that support blood flow to brain tissue and may protect cells from oxidative stress [4][7]. Research is mixed, but some analyses find modest improvements in working memory, attention and mood in healthy adults or older populations with memory difficulties. Ginkgo might also help with normal age-related cognitive slowdown. Its effects tend to be more subtle and can take several weeks of consistent supplementation to appear.
Ginseng Korean (Panax ginseng):
Panax ginseng’s use has a long history. Studies suggest it can improve attention, mental arithmetic and mood [12][20]. It helps with the modulation of neurotransmitter activity and as an antioxidant. Ginseng extracts may help sustain mental performance during prolonged tasks. Although not a stimulant like caffeine, repeated intake over days or weeks can yield improvements in mental energy and resilience. It can therefore help in managing cognitively demanding periods.
Phosphatidylserine (PS):
Phosphatidylserine is a phospholipid found in cell membranes, including neurons, where it supports membrane fluidity and signal transmission [10][14]. Studies have found that PS supplementation can improve memory, learning and attention, including in older individuals experiencing mild cognitive decline. It can also help athletes maintain mental sharpness during physical exertion. While not a quick fix, sustained use of PS may improve brain health as well as helping maintain processing speed and working memory.
Pine Bark Extract (Pycnogenol):
Pine bark extract when standardized to pycnogenol, contains procyanidins and other antioxidants which may help sustain vascular function and reduce oxidative stress in brain tissues [19][23]. Some controlled trials have found improvements in working memory, attention and mood after weeks of use. It may also enhance microcirculation, supporting oxygen and nutrient delivery. Consistent supplementation has also been shown to yield improved scores in mental performance tests.
Spanish Sage (Salvia lavandulifolia):
Spanish sage is a herb and has been linked with positive impacts on cholinergic systems and memory function [24]. Extracts or essential oils from Spanish sage can enhance short-term memory and attention. Some trials with healthy adults found improved performance during certain cognitive tasks within hours of first use. The plant’s interaction with the cholinergic system suggests a plausible mechanism for supporting processing speed and concentration during mental activities.
Caffeine:
Caffeine is amongst the most widely used stimulants worldwide [2][16]. Caffeine works by blocking adenosine receptors, meaning it can temporarily reduce fatigue and sharpen alertness. Many experiments confirm caffeine’s effect on reaction times and simple attention. Its impact on complex reasoning or memory is modest, but some people find it useful for short-term tasks. Caffeine tolerance can develop, so moderate and sensible intake is key. Excessive amounts may cause restlessness, sleep disturbance, or irritability.
“All-in-One” Nootropic Supplements:
How To Get The Best Results
Dosage and Quality:
Standardized extracts and purity testing help assure the intended ingredient is present in the required amount. Overdosing or using poor-quality products may reduce benefits or raise safety concerns [16][21].
Lifestyle Factors:
Ample sleep, whole-food nutrition, basic physical activity and stress relief techniques can improve the improvements experienced [9][12]. Even the best supplement cannot compensate for chronic sleep deprivation or nutrient-poor diets.
Individual Differences:
Genetic factors or existing conditions can influence how one responds to nootropic supplementation [2][23]. If you’re unsure consultat with a physician, pharmacist, or a well-informed dietitian.
Safety Considerations and Potential Side Effects
Start slowly and watch out for headaches, nausea, or restlessness. Some nootropics may interact with medications, so those on prescriptions should exercise care or get medical input. Look for companies that follow good manufacturing practices and disclose ingredient details [17][24]. Avoid products making grandiose claims without references. Each person’s tolerance varies, and what feels helpful for one may not suit another.
How to Choose the Right Nootropics for You
Define your personal aims. Whether its memory support, improved concentration for a project, or maintaining cognitive steadiness during tough periods. Consult credible sources or peer-reviewed journals. Reliable brands may highlight clinical data and should have transparent labeling. Take notes when trying new nootropics and see whether any measurable improvements occur. Give each change time and adjust course if necessary.
Frequently Asked Questions (FAQ)
Do nootropics really work?
Many nootropics have be proven to deliver tangible benefits in controlled studies, but clinical evidence for others is less clear [1][5].
How long does it take to notice benefits?
Quick-acting compounds like caffeine may work within minutes. Herbal extracts like Bacopa or Ginkgo might require weeks of steady use [4][20].
Can I combine multiple nootropics?
It is possible, but introduce new ones gradually. Some combinations are common (e.g., L-Theanine with caffeine). Start low and note any changes. Better yet, using an all-in-one nootropic can be a good way to combine different nootropics at safe and effective levels [22][23].
Are nootropics safe for long-term use?
Safety depends on the substance. Long-standing traditional herbs and vitamins have longer histories of safe use, while newer synthetics may lack extensive data [6][25].
Do nootropics replace lifestyle factors like sleep and diet?
They cannot stand in for proper rest, balanced meals, and physical movement. They can help when the basics of a healthy lifestyle are in place [12][19].
Recap
Nootropics include vitamins like B6 or B12, herbal extracts such as Bacopa, compounds such as Citicoline and even well-known stimulants like caffeine. Each has the potential to improve mental performance, but none should be considered a miracle. Good research, cautious experimentation and a foundation of healthy habits can lead to better results.
