Nootropics as Cognitive Enhancers: Types, Dosage and Side Effects of Smart Drugs

Ginkgo biloba is used in traditional Chinese medicine as a treatment for symptoms of dementia and for its supposed nootropic effects. Although research supporting its positive effect on cognitive function is limited and unclear, the supplement is generally well-tolerated and safe to use in most populations, barring those with bleeding disorders. 

Ginkgo (Ginkgo biloba)

Maca root is prepared and consumed in a number of ways in South America, and has been shown in mice studies to demonstrate neuroprotective effects which are thought to aid against cognitive deterioration over time. In humans, it has been found to be safe and well-tolerated.

Maca (Lepidium meyenii)

Centella asiatica is prepared, consumed, and utilized in multiple ways for its strong antioxidant properties. Due to this and its purported nootropic and anxiolytic effects, it is used in traditional medicine and is thought to show promise in treating illnesses like Alzheimer's disease.

Eleuthero (Eleutherococcus senticosus)

Rhodiola's plant extract has demonstrated neuroprotective effects. Likewise, human trials have indicated its potential benefit in treating anxiety, depression, and other mood-related issues, and mouse studies have confirmed these antidepressant and anxiolytic effects in addition to potential stimulant and adaptogen properties. However, it is not recommended for many groups of people, such as those with hypertension or certain psychotic disorders, pregnant and breastfeeding individuals, and children. 

Rhodiola (Rhodiola rosea)

Schisandra's seeds and fruits are prepared in a variety of ways, often consumed as a drink for its stimulant effects. One component of the plant, schisantherin A, has been demonstrated to have neuroprotective effects in mouse studies and may be promising in treating symptoms of neurodegenerative disorders like Parkinson's disease.
