Nootropics Guide: Complete Guide to Cognitive Enhancement Supplements

Nootropics, often called “smart drugs” or cognitive enhancers, are substances that may improve cognitive function, memory, creativity, or motivation in healthy individuals. From ancient herbal remedies to cutting-edge synthetic compounds, nootropics represent a fascinating intersection of neuroscience, psychology, and human optimization.

What Are Nootropics?

The term “nootropic” was coined in 1972 by Romanian psychologist and chemist Corneliu E. Giurgea, who defined several criteria that substances must meet to be considered true nootropics:

Giurgea’s Criteria:

Enhancement of Learning and Memory: Improve acquisition and retention
Resistance to Brain Damage: Protect against physical or chemical injury
Increased Efficacy: Enhance neuronal firing control mechanisms
Low Toxicity: Minimal side effects and high safety profile
Evidence-Based: Measurable effects in humans

Modern Definition:

Today, the term “nootropic” is used more broadly to describe any substance that may enhance cognitive performance, including:

Prescription medications
Dietary supplements
Natural compounds
Synthetic research chemicals
