What Are Nootropics? A Simple Definition

 

 

The term "nootropic" sounds complicated, but the definition is fresh and theoretical. The chemist that coined "nootropic" in 1972, Dr. Corneliu E. Giurgea, created the term with the Greek words noos (mind) and tropos (turning).

 

Essentially, nootropics are "brain enhancers"—compounds that are able to help turn your brain on.

 

Scientific in Simple Terms

 

Nootropics accomplish several goals when supporting the brain:

 

• Increasing Neurotransmitter Levels: They are generally able to synthesize or modulate the brain's chemicals, including dopamine (for motivation), serotonin (for mood), and acetylcholine (for memory).
  
  

• Increasing Brain Energy: They support mitochondrial function, which are like the tiny batteries in the cells where the energy to carry out the hard work of the brain is produced.
  
  

• Increasing Resistance to Stress: They help modulate the body's stress response system, which can defend the brain from mental fatigue and reduce brain fog due to excess cortisol.
  
  

There are several classifications of nootropics:

 

• Natural Nootropics: These are derived from food (like adaptogens), amino acids, or vitamins and minerals that have been used by people for centuries to support cognition.
  
  

• Synthetic Nootropics: These compounds are synthetic drugs, like racetams.
  
  

At Jaan, we only sell evidence-based natural nootropics. We believe the most effective solutions come from nature, upregulated by modern science.

 

Why Bioavailability is the Secret to Success

 

Here's a tidbit that many supplement brands will not tell you: the majority of nootropics fail, because the body simply can't properly absorb them in an effective way. You can consume the best ingredients in the world, but if they do not target your brain cells, they can't do their job.

 

This is exactly why Jaan is a game changer. The proprietary IPH AVN and AEN Peptides are short-chain amino acids that serve as cellular guides - essentially helping deliver vitamins, minerals, and other essential nutrients to your brain and nervous system directly. This means enhanced absorption, improved effectiveness, and measurable results.

How Nootropics Improve Brain Function (And the Jaan Ingredients that do it Best)

 

 

Let's break down the core functions of a healthy brain - and then look specifically at the unique, evidence-based ingredients included in Jaan ' formulas that support these functions.

 

A. For Lasting Energy & Mental Endurance.

 

Mental fatigue can sabotage the most productive days. Instead of using stimulants that could lead to a crash, these ingredients provide sustained cognitive energy from the cellular level up.

 

Beta-Alanine (from Jaan Brain Boost)

 

• What it does: During periods of intense mental effort, your brain creates lactic acid just like your muscles do during physical exercise. Beta-Alanine provides a buffer against the lactic acid, which delays mental fatigue.
  
  

• The result: You are able to maintain higher levels of focus and cognitive function over a longer period, especially when pressure is applied.
  
  

• The science: A study in the Journal of Applied Physiology stated that Beta-Alanine supplementation improved cognitive performance and reduced fatigue during combat simulation tests in soldiers.
  
  

• Included in: Jaan Brain Boost
  
  

The B-Vitamin Complex (from Jaan B-Vitamin Complex)

 

• What it does: Thiamin (B1), Riboflavin (B2), Niacin (B3), B6, B12, Biotin, and Folate are the unsung heroes of energy metabolism. They are absolutely required for converting food into cellular fuel (ATP) and they will help synthesize important neurotransmitters such as dopamine and serotonin.
  
  

• The result: A fully fueled brain with balanced brain chemistry, stable energy, and a brighter mood.
  
  

• The source: The Mayo Clinic confirms that B-vitamins play a vital and direct role in brain function, and cellular energy production.

B. For Laser Focus & Mental Clarity

 

Distraction is the antithesis of progress. Nootropics can help shut out the mental clatter that is clamoring for your attention so you can begin to focus on what you want to do, and begin to flow.

 

L-Leucine & L-Lysine (these are in Jaan Brain Boost)

 

• What they do: These amino acids are essential raw ingredients for brain health. Leucine is especially important in that it has a role in many dopamine signaling pathways for keeping able to focus and stay motivated. Lysine will help put balance in neurotransmitters and help repair brain cells.
  
  

• The Result: A more stable and focused mind, with the bandwidth to stay on task.
  
  

• The Science: A recent research article in Frontiers in Aging Neuroscience first describes leucine's potential role as a modulator for cognitive health, and its protective role against a lifetime of age-related decline.
  
  

Adaptogens: Ashwagandha, Rhodiola & Ginseng (these are in Jaan Metabolic Adaptogen & Male Vitality)

 

• What they do: Adaptogens are a special class of herbs which we classify as adaptogens because they help your body to adapt to stress. Adaptogens lower HPA axis activity, which is primarily a lower cortisol response, and high levels of cortisol are associated with brain fog and unreliability of thoughts.
  
  

• The Outcome: Improved mental clarity and continued attention even on long workdays or heavy projects especially in stressful scenarios.
  
  

• The Evidence: The National Institutes of Health (NIH) database includes many studies, such as a review on their neuroprotective benefits; many studies show that adaptogens increase tolerance to cognitive load and mental stress.

C. For improved memory & mood balance

 

Your ability to access stored information and a positive perspective are closely tied. These ingredients give support to the underlying systems responsible for emotional regulation and memory formation.

 

L-Glycine (from Jaan Brain Boost)

 

• What it does: Glycine is an amino acid that acts as an inhibitory neurotransmitter (meaning it has a calming effect on the brain). It is known to improve the quality of sleep - a critical process for memory consolidation.
  
  

• The Outcome: Better sleep, improved memory retention, and a more balanced mood the next day.
  
  

• The Science: In studies from the Journal of Psychiatric Research, it has been shown that glycine supplementation leads to significant improvements in sleep quality and memory performance following an hour's sleep.
  
  

Choline & Inositol (from Jaan B-Vitamin Complex)

 

• What they do: Choline is a direct precursor to acetylcholine, the brain's core neurotransmitter for memory and learning. Inositol works behind the scenes to modulate other mood-related neurotransmitters like serotonin and dopamine.
  
  

• The Result: Better recall memory and ultimately feel more stable and resilient emotionally.
  
  

• Where they usually get referenced: Leading institutions such as Harvard Health, & Mount Sinai, have referenced choline's essential role in cognitive function, and inositol in support of mood.
