In this article, we’ll also share practical guidelines for those considering adding nootropics to their wellness routine, ensuring safe and effective use.

Let’s get started.

What are Nootropics?

Nootropics, a term coined by Romanian psychologist and chemist Dr. Corneliu E. Giurgea in the 1960s, are substances designed to enhance cognitive performance.

Derived from the Greek words “nous” (mind) and “trepein” (to bend), nootropics are thought to “bend the mind” towards improved mental and cognitive function, such as memory, focus, and mood.

Dr. Giurgea’s pioneering work laid the foundation for the modern understanding of nootropics. His criteria for these substances included enhancing learning and memory, protecting the brain against various forms of damage, and exhibiting low toxicity and side effects.

Nootropics are more than just performance enhancers; they potentially offer protective properties for the brain and are also being studied for their role in addressing cognitive impairments associated with various health conditions like attention deficit hyperactivity disorder (ADHD), age-related cognitive decline, and even cognitive impairments related to anxiety and depression.

Types of Nootropics

Nootropics come in many forms, each with unique characteristics and potential benefits. These substances interact with our brains in different ways, such as influencing the activity of brain chemicals or enhancing the brain’s natural processes.

Understanding the various types of nootropics helps us better grasp how they may improve cognitive functions like memory, attention, and mood when exploring the use of nootropics for cognitive enhancement or managing cognitive impairments associated with various health conditions.

In this section, we’ll learn about the different types of nootropics, from natural extracts to synthetic compounds, and discuss how they contribute to cognitive enhancement.

Synthetic Nootropics

These are man-made nootropics often developed for medical purposes but also used off-label for their cognitive enhancement properties.

Racetams are a family of synthetic compounds known for their diverse cognitive benefits. Each member of this family has unique properties:

  • Piracetam is believed to improve memory and cognition, though the exact mechanism is still not fully understood.
  • Aniracetam is known to affect serotonin and dopamine, potentially improving mood and reducing anxiety. It also may enhance memory and learning.
  • Oxiracetam is considered a true cognitive enhancer, as it may positively impact memory, learning, and attention span.
  • Phenylpiracetam is thought to have a broader range of effects, including improved cognition, motor function, and even cold resistance. It’s also known to have a stimulatory effect.
  • Pramiracetam is highly potent and is believed to improve memory and learning and may even enhance motivation and productivity.

Natural or Herbal Nootropics

These are substances found in nature that have cognitive-enhancing properties.

  • Ginkgo Biloba is a plant extract known for its potential memory-enhancing effects. It’s believed to improve blood flow to the brain and act as an antioxidant.
  • Bacopa Monnieri is an Ayurvedic herb believed to improve cognition and reduce stress. It’s thought to boost brain function by enhancing the communication of brain cells and reducing inflammation within the brain.
  • L-theanine is an amino acid found in green tea that has a relaxing effect without causing drowsiness. Combined with caffeine, it promotes focus and attention while reducing the jitteriness that caffeine can sometimes cause.


These are food-derived substances with potential health benefits beyond basic nutritional value.

  • Omega-3 fatty acids, especially DHA and EPA, are essential for brain health. They contribute to cell membranes’ fluidity and neurotransmitters’ functioning, which is critical for brain function.
  • Curcumin, derived from the spice turmeric, is believed to have neuroprotective properties due to its potent antioxidant and anti-inflammatory effects.
  • Caffeine is a natural stimulant in various plants, including coffee and tea. It blocks adenosine receptors in the brain, leading to increased alertness, attention, and wakefulness.

Smart Drugs

These substances, often prescription medications, are used off-label for their cognitive-enhancing effects.

Adderall and Ritalin are stimulants prescribed for ADHD but are often used by healthy individuals for their attention and focus-enhancing effects. They increase the availability of neurotransmitters in the brain, including dopamine and norepinephrine.


These short chains of amino acids can have various effects on the body and brain.

Noopept is a peptide-derived nootropic believed to improve memory, cognition, and mood. It’s thought to work by stimulating the expression of two chemicals, NGF and BDNF, which play a crucial role in cognitive function and brain health.

How Nootropics Work?

Nootropics operate through a series of complex biological mechanisms to enhance cognitive functions. Their effects can be widespread, influencing various neural pathways and biochemical processes.

Here are some of the primary ways nootropics work:

Neurotransmitter Modulation

Neurotransmitters are the brain’s chemical messengers that play crucial roles in cognitive functions like memory, attention, mood, and alertness.

Nootropics may influence neurotransmitters’ production, release, or breakdown and modulate their activity.

For instance, racetams, particularly piracetam, enhance cognitive function by improving the efficiency of the neurotransmitter acetylcholine, a key in learning and memory processes.

Natural nootropics like Bacopa Monnieri may affect serotonin and dopamine, neurotransmitters influencing mood and motivation.

Neuroprotection and Neurogenesis

Some nootropics may protect brain cells from damage caused by inflammation, oxidative stress, or aging. They can also promote the growth of new neurons, a process known as neurogenesis.

For example, curcumin, found in turmeric, has potent antioxidant and anti-inflammatory effects that can protect brain cells from damage.

The peptide nootropic, Noopept, is believed to stimulate the expression of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF), proteins that play a critical role in neurogenesis and maintaining the health of neurons.

Cerebral Circulation Enhancement

Some nootropics may enhance cognition by improving blood flow to the brain and increasing the supply of oxygen, glucose, and nutrients brain cells need to function efficiently.

Ginkgo Biloba, for instance, is known for its potential to improve blood flow to the brain, which may contribute to better cognitive performance.

Stress Resistance

Some nootropics may help the brain resist or recover from stress. They could potentially reduce the harmful effects of chronic stress on cognition and brain health.

Adaptogens like Rhodiola Rosea are believed to help the body maintain homeostasis during stressful situations, thereby potentially preserving cognitive function.

By understanding these mechanisms, we can better appreciate how nootropics may enhance cognitive function and potentially support brain health over time.
