Top 5 Organic Nootropics For Your Memory

We know that nootropics are used to enhance cognitive function, including memory. However, evidence for many is limited or mixed, with small effect sizes in most studies. Some have been studied more than others in placebo-controlled trials. Below is a list of 5 organic nootropics with some evidence for memory support. 

Bacopa Monnieri is one of the more researched herbal nootropics for memory. Across multiple placebo-controlled human trials, it has demonstrated moderate improvements in certain memory domains, particularly delayed recall and information retention, typically after consistent use for around 12 weeks or longer. Evidence also suggests small supportive effects on learning and attention, though results vary between extracts and study designs, and the average effect size remains modest. Reported side effects mostly involve digestive discomfort, such as increased stool frequency or nausea. Bacopa is widely sold as a dietary supplement in countries such as the United States, the United Kingdom, Canada, Sweden, and Australia.

Extracts of sage have been investigated in several small studies examining acute and short-term cognitive effects. These trials report minor improvements in memory performance and attention compared with placebo, though the total number of participants across studies remains relatively low. Some research also hints at small benefits on alertness and subjective cognitive state. Overall, results appear promising but require larger and longer-term research to determine reliability. Sage may cause gastrointestinal upset or allergic reactions in sensitive individuals. Sage-based supplements are legally available in the United States and Canada.

Curcumin, the active compound found in turmeric, has been evaluated in multiple human trials, primarily in older adults or individuals with mild cognitive concerns. Across these studies, curcumin supplementation produced small improvements in memory performance and general cognitive measures relative to placebo, although total participant numbers remain limited and bioavailability differences across formulations complicate interpretation. Evidence also suggests potential mood-supporting effects, but these remain preliminary. Gastrointestinal discomfort is the most commonly reported side effect. Turmeric and curcumin supplements are permitted for purchase and use in the United States, the United Kingdom, Sweden, Canada, and Australia.

American ginseng has been examined in controlled human research focusing on aspects of cognitive performance. Results indicate slight improvements in memory accuracy and short-term cognitive processing compared with placebo, though the total body of evidence is still relatively small and based on short study durations. Some findings point to mild improvements in subjective stress or mental fatigue, but these require further confirmation. Possible side effects reported across research include insomnia, headaches, and blood pressure changes. American ginseng is legally available as a dietary supplement in the United States and Canada.

Ginkgo Biloba is one of the most commonly studied herbal cognitive supplements. Across multiple placebo-controlled trials, it has shown small positive effects on memory performance, cognitive speed, and attention, though results vary and the average improvement tends to be modest. Some research also reports slight support for mood and focus. Despite a long research history, findings remain inconsistent—benefits appear more likely in older adults or those experiencing cognitive decline rather than in young, healthy individuals. Reported risks include headaches, digestive upset, and bleeding-related concerns due to antiplatelet activity. Ginkgo is legally sold in the United States, the United Kingdom, Sweden, Canada, and Australia.

While these natural nootropics show some evidence of supporting memory and broader cognitive function, effect sizes are generally small, and results differ between individuals and study designs. Many trials involve limited sample sizes and short durations, making it difficult to draw firm conclusions about long-term impact or effectiveness in healthy populations. There is significant individual variability in response, meaning some people may experience noticeable improvements while others may notice none. More robust, long-term research is needed to clarify optimal dosing, target populations, and the reliability of effects.
