Defining Nootropics and Adaptogens

Nootropics and adaptogens may sound like terms from a science fiction novel, but they’re more accurate and beneficial than you might think. Nootropics, often referred to as “smart drugs,” are substances that may potentially enhance mental performance. Adaptogens, on the flip side, are naturally occurring herbs and plants recognized for their capacity to assist the body in managing stress.

But let’s study these intriguing compounds more thoroughly through a systematic review.

What are Nootropics?

Nootropics boost cognitive functions, such as memory, creativity, and motivation. They achieve this by stimulating neurotransmitters and protecting brain cells from toxins. Just think of them as dietary supplements for your brain.

Nootropics, including nootropic supplements, can come in many forms, from natural dietary supplements to prescription drugs. They can include substances like piracetam, noopept, and meclofenoxate, which are accessible in a variety of forms. Though these substances come in various forms, they all aim to elevate mental function.

The way nootropics work can vary, but most function by:

  • Enhancing blood circulation to oxygenate the brain and support the central nervous system
  • Decreasing inflammation
  • Safeguarding the brain from toxins
  • Regulating cholinergic systems, which are associated with memory and attention

Some nootropics may also help address cognitive impairment.

What are Adaptogens?

Adaptogens, on the other hand, are natural herbs and plants that help the body handle stress. They are known to regulate cortisol levels and support the nervous, immune, and endocrine systems, which can help in dealing with stress-related disorders.

Adaptogens contain active compounds such as complex phenolics or tetracyclic triterpenoids/steroids. These compounds significantly contribute to the beneficial stress-protective effect of adaptogens, which regulate homeostasis through mechanisms related to the Hypothalamic Pituitary Adrenal (HPA) axis and key mediators of the stress response.

Adaptogens manage the body’s response to stress by:

  • Modulating the release of cortisol and other stress hormones
  • Improving the functioning of three crucial systems: the nervous, immune, and endocrine systems
  • Aiding in addressing stress-induced impairments and disorders associated with these systems.

Comparing Nootropics and Adaptogens

While both nootropics and adaptogens pack a punch in the health department, they are not precisely the same. Nootropics are designed to improve brain health and cognitive function, whereas adaptogens primarily focus on mitigating mental and physical stress.

The differences between these two types of substances are significant, but they can complement each other when used correctly.

Primary Aims

The primary aims of nootropics are to augment cognitive performance, enhance brain function, and improve memory retention. By enhancing the brain’s supply and function, nootropics can have psychostimulating and antiasthenic effects.

On the other hand, the primary goals of adaptogens are to restore the body to a state of balance (homeostasis) and to increase the body’s resilience to stress. This balance is essential for maintaining a healthy body and mind.

Hence, while nootropics target enhancing brain health and cognitive performance, adaptogens focus on reducing both mental and physical stress. These substances have different primary aims, but they can work together in a complementary manner to promote overall health and well-being.

Effects on Cognitive Performance and Stress Reduction

Both nootropics and adaptogens can positively affect cognitive performance and stress reduction. Nootropics enhance cognitive performance by optimizing the brain’s supply of neurochemicals. Studies indicate their potential in treating memory, consciousness, and learning disorders.

Adaptogens, on the other hand, contribute to stress reduction by modulating the HPA axis, suppressing JNK and cortisol levels, stimulating HSP70 production, and activating signalling pathways. Their neuroprotective, anti-fatigue, antidepressive, anxiolytic, and nootropic effects contribute to the body’s stress resistance.

Nootropics and adaptogens can be complementary. For instance, Rhodiola serves both purposes and demonstrates benefits for cognitive function and stress alleviation, indicating synergistic effects when combined with complementary and integrative health approaches.

Common Nootropics and Their Benefits

Shifting from nootropics, let’s examine some popular adaptogens and their benefits. We’ll look at three commonly used adaptogens: Ashwagandha, Rhodiola Rosea, and Reishi Mushroom.


Ashwagandha, also known as Indian ginseng or winter cherry, is one of the most widely used adaptogens, similar to panax ginseng. It helps regulate cortisol levels, supports sleep-wake cycles, and is a potent antioxidant.

Ashwagandha regulates cortisol levels by decreasing its production and restoring its balance in the body, consequently alleviating stress and anxiety. It also aids in regulating the sleep-wake cycle by enhancing sleep quality and decreasing the time it takes to fall asleep.

Besides these benefits, Ashwagandha is perceived as a powerful antioxidant due to its inherent anti-inflammatory properties, which help fight oxidative stress in the body.

Rhodiola Rosea

Rhodiola Rosea is another popular adaptogen known for reducing stress and anxiety, improving mood, and enhancing strength and stamina. It helps the body manage stress by increasing resilience, safeguarding the brain and heart during stressful situations, and reducing anxiety.

Rhodiola Rosea extract has demonstrated the ability to prevent exhaustion and fatigue during prolonged intensive mental activity tasks. Reducing stress and anxiety is also noteworthy for its ability to decrease fatigue.

Rhodiola Rosea extract should be taken at 5–25 drops, three times daily in a quarter of a glass of water, 15–30 minutes before meals. This dosage is considered optimal for its effectiveness. The duration of therapy may range from 10 days to 4 months, tailored to the individual’s specific requirements.

Reishi Mushroom

Reishi Mushroom, a key component in traditional Chinese medicine, is a powerful adaptogen that modulates the immune system, provides anti-inflammatory and anti-ageing benefits, and helps with anxiety and sleep. It influences hematopoietic stem cells, lymphocytes, macrophages, T cells, and dendritic cells, which may result in a more robust immune response.

Reishi Mushrooms offer anti-inflammatory benefits due to their substantial antioxidant content, which effectively diminishes inflammation and can enhance overall immunity.
