Nootropics are colloquially known as 'smart drugs' – substances that increase cognitive function in healthy people. The word nootropic is a combination of two Greek words, noos meaning 'mind' and tropein meaning 'towards'.
Dave Asprey discusses two naturally occurring smart drugs: Caffeine and nicotine. The latter might be a surprise, but while smoking, chewing tobacco and vaping have negative health consequences, there's evidence to suggest microdosing one milligram of nicotine, about 5% to 10% of a cigarette's worth, may protect against Alzheimer's.
Beyond naturally occurring smart drugs, Asprey discusses aniracetam, a pharmaceutical cognitive enhancer pioneered in Russia that may improve memory input and recall.
