What are nootropics?
What are the key benefits of nootropics, according to science?

Improved focus and attention:
Several studies have found that certain nootropics can improve the quality of our focus, especially during lengthy work-related tasks. They can help us stay sharper, more alert, and more focused during the day - which may in turn improve our productivity.

Enhanced mental clarity:
Nootropics are also known to be very effective at clearing “brain fog”. Many people who take nootropics report having a clearer mind and an improved ability to think straight. This can be explained by the several brain-boosting hormones that nootropics are capable of stimulating, including serotonin and dopamine.

Improved memory:
Studies also indicate that certain nootropics may improve both short-term and long-term memory, allowing people to retain information faster and longer.

Increased mental energy:
According to studies, some nootropics have been found to significantly reduce mental fatigue and boost mental energy and vitality. They can keep our brain sharper and more energetic throughout the day.
What are the main types of nootropics?

Synthetic drugs:
Drugs created by pharmaceutical companies, such as Modafinil or Adderall. These drugs have been proven to increase alertness and cognitive function, but they also come with a range of undesirable side effects (more on that later).

Natural nootropics:
Natural ingredients typically found in plant or herbal extracts, capable of boosting the brain capabilities with fewer side effects than synthetic nootropics. Well-researched natural nootropics include caffeine, L-Tyrosine, and Panax Ginseng, to name a few.
Why nootropic drugs should be avoided, according to brain health specialists
Synthetic nootropics have been proven to improve cognition in multiple studies. Modafinil, for example, a common nootropic drug, has been clinically found to boost cognitive function, improve working memory, and enhance problem-solving skills.

"In acute studies from my laboratory at the University of Cambridge, we have shown that methylphenidate and modafinil as compared with placebo do enhance cognition in healthy people,"
— says Barbara Sahakian, DSc, FBA, FMedSci, Professor of Clinical Neuropsychology in the Department of Psychiatry at the University of Cambridge.

"While products like modafinil offer a fast track to sharper focus, they're not without their drawbacks. These cognitive-enhancing drugs tend to come with many unwanted side effects that may permanently affect brain chemistry. On the other hand, many natural nootropics, backed by solid research and history, provide similar cognitive boosts but with significantly fewer and less severe side effects."
— Dr. Alexander Bennett, Neuropharmacology and Brain Health Specialist

"We have seen, for example, improvements in working memory, planning, and problem-solving. We have also shown that modafinil enhances task-related motivation; people found doing the tests and tasks more enjoyable with modafinil. This was not a general euphoric effect, which may be why modafinil is used by people as a 'work drug.'"
— That being said, drugs like modafinil also come with serious side effects in the long-term, which may include:
- Nausea
- Dizziness
- Irregular heartbeat
- Fever
- Swollen lymph nodes
- Difficulty breathing
That’s why health specialists tend to recommend natural nootropics instead of synthetic ones. They can be just as effective in boosting cognitive performance, with less pronounced side effects. Some of them are even free of side effects, as we’ll discuss later.
Which nootropics are safe and effective?
Certain nootropics can indeed boost your cognitive performance and help you function at your best. But if you want to try nootropics, it’s best to make sure that those are not only effective but also safe to use on the long-term.
We’ve examined scientific literature to identify a few proven natural nootropics that have been found to enhance cognitive function with excellent safety profiles. For each natural nootropic, we also mention the potential side effects they may produce.

L-Tyrosine
L-Tyrosine is a natural amino acid mainly in high-protein foods, such as nuts, fish and beans. This molecule is known for boosting mental sharpness, without creating jitters or overexcitation often associated with caffeine.
Clinically proven benefits:
- Enhances focus and mental clarity. L-Tyrosine has been shown to improve attention, focus and mental clarity, especially when combined with caffeine.
- Improves cognitive flexibility. Enhances the brain’s ability to switch smoothly between tasks or thoughts,
- Reduces stress and promotes relaxation. The molecule promotes relaxation without causing drowsiness, by promoting healthy neuronal activitiy
- Improves stress resistance. L-tyrosine can enhance cognitive performance under stressful conditions, by boosting certain neurotransmitters like dopamine and norepinephrine
Effects of Tyrosine on mental accuracy

In a placebo-controlled study evaluating the effect of L-Tyrosine on cognitive flexibility, participants showed 91% mental accuracy during an n-back task, compared to 87% for placebo
Potential side effects (rare):
- Dizziness
- Headache
- Stomach discomfort

Ginger root
Ginger is a flowering plant that has been used in ancient medicine for thousands of years. While the plant is well known for its benefits on digestion and inflammation, it could also deliver powerful cognitive-enhancing benefits, according to recent research.
Clinically proven benefits:
- Enhances cognitive function. Studies suggest that ginger root extract may improve memory and reaction times in cognitive tests.
- Improves mood and reduces depressive symptoms
- Combats oxidative stress, supporting brain health
- Protects the brain against certain neurodegenerative diseases
Potential side effects (rare):
- May cause stomach issues, such as diarrhea
- Can interfere with some medications, especially those for diabetes and hypertension
- May cause allergic reactions including itching or skin rash

Panax ginseng
Panax ginseng is an ancient medicinal plant traditionally used in Chinese medicine. It’s well known for its powerful adaptogenic properties, helping the body fight stress and function better. Recent studies indicate that it may improve cognitive function and mental clarity, which makes it a particularly effective natural nootropic.
Clinically proven benefits:
- Improves memory and cognitive function. Studies suggest that panax ginseng can improve memory, focus and attention in healthy subjects, allowing them to perform better in cognitive tasks.
- Reduces mental fatigue. Can help reduce work-related fatigue and boost cognitive performance in tasks requiring prolonged attention.
- Reduces stress. Due to its adaptogenic benefits, panax ginseng can help the body feel more relaxed, less stressed, which may indirectly benefit cognitive function
Effects of Tyrosine on mental accuracy

In a placebo-controlled study evaluating the potential benefits of ginseng on fatigue, ginseng was found to significantly decrease fatigue perception compared to placebo. These findings indicate that ginseng may be an effective natural solution to reduce fatigue and promote healthy energy levels during daytime
Potential side effects (rare):
- Headache
- Insomnia

Caffeine
Caffeine is one of the most well-known cognitive stimulants in the world. Found naturally in coffee beans, tea leaves, and other plants, caffeine can improve focus, alertness, cognitive performance, making it a popular ingredient in nootropic supplements.
Clinically proven benefits:
- Increases alertness. The mind is more alert after caffeine consumption, enhancing immediate responsiveness.
- Improves concentration and focus due to elevated attention
- Enhances short term memory. Studies show improvements in short-term recall after caffeine consumption
Potential side effects (rare):
- Jitters (common)
- Insomnia
- Upset stomach
- Dependance
What are the key things to look for in a nootropic?
Must use a sufficiently high dose of each ingredient. Low doses are unlikely to work.
Many nootropic supplements use low doses of nootropic ingredients to reduce production costs. This can be a problem as low doses are unlikely to produce any noticeable effects on brain cognition. For example, dieticians recommend a dose of at least 150 mg of tyrosine for optimal effects. For panax ginseng, at least 200 mg is recommended. Any dose below that is likely to produce mild cognitive benefits at best.

Only use natural nootropic ingredients that have been clinically studied.
There are plenty of commercialized nootropics that don't use clinically proven ingredients, or the ingredients they use are backed by very little clinical evidence. To feel a strong and healthy cognitive boost, it's important to choose nootropics that only contain ingredients with clinically proven cognitive benefits. These well-studied nootropics include: L-theanine, ginger, panax ginseng, caffeine, theobromine, among others.
Produce a significant and long-lasting cognitive boost.
Many nootropic supplements on the market produce a mild cognitive boost, especially if they contain low-dose ingredients. If you're looking to boost your cognitive performance, it's better to choose supplements that create strong and long-lasting brain-boosting effects, using high-dose natural nootropics. Certain nootropics can produce a major, clearly perceptible cognitive boost for several hours in a row (we present some of these below)
Free of any major side effects.
To get the benefits without the bad side (jitters, energy crashes, anxiety), only choose supplements that cause no to minimal side effects. In general, supplements made of natural and clinically tested nootropics such as L-theanine or ginseng are very safe and free of side effects. That means they can be taken every day without causing any issues. It's however always advised to consult with a health specialist before taking health supplements
Doesn't contain aspartame or acesulfame potassium
Unhealthy artificial sweeteners such as aspartame or acesulfame potassium (often used as sweeteners in nootropic supplements, specifically drinks) should be avoided. These chemicals can destroy gut health and have bad long-term consequences on your body.
What to avoid:
Cause jitters or energy crashes
Use ingredients that haven’t been clinically tested
Excessive use of synthetic nootropic ingredients
Contain aspartame or ace-K
