WHAT ARE “NOOTROPICS"?
Nootropics is an umbrella term for a class of chemicals — some naturally-occurring, some manmade — that give cognitive benefits to the human brain.
To get really technical, in order to be a nootropic, a substance must meet five criteria set by Dr. Corneliu E. Giurgea, the man who coined the term “nootropic.”
The substance must…
Enhance memory and ability to learn.
Help the brain function under disruptive conditions, such as hypoxia (low oxygen) and electroconvulsive shock.
Protect the brain from chemical and physical assaults, such as anti-cholinergic drugs and barbiturates.
Increase the efficacy of neuronal firing control mechanisms in cortical and sub-cortical regions of the brain.
Possess few or no side effects and be virtually non-toxic.
