- Increases enzymes and transporters that increase serotonin (TPH2, SERT), which is involved in learning and memory enhancement [R].
- Increases antioxidant enzymes (SOD, catalase, GPx, GSR) and glutathione, protecting the brain from oxidative stress [R].
- Increases brain blood flow by increasing nitric oxide (NO) production and inhibiting calcium fluctuations. This is vital to memory and brain health [R].
3) Huperzine A Improves Memory
Parkinson’s and Alzheimer’s disease patients experience degeneration in a region of the brain (nucleus basalis). In an animal model, Huperzine A restored healthy brain electrical activity (EEG). In animals suffering from lesions in this brain region, Huperzine A reduced the decay in cognitive and memory functions caused by the lesions [R].
Huperzine A enhanced the memory and learning of junior middle school students complaining of memory problems [R].
Huperzine A holds multiple neuroprotective effects [R].
How Huperzine A Improves Memory (Mechanisms)
- Increasing acetylcholine by inhibiting acetylcholinesterase [R].
- Increasing levels of NGF, BDNF, and TGF-Beta. These protect the brain and improve memory and learning ability [R].
In mice with reduced blood flow to the brain (chronic cerebral hypoperfusion), Huperzine A treatment reduced cognitive impairment by [R]:
- reducing myelin damage
- decreasing inflammation and white matter lesions
- reducing cell death
- improving learning and memory [R]
- reducing inflammation (TNF-alpha)
- reducing negative effects of low oxygen, significantly improving cognitive impairment
4) Semax Improves Memory

Sodium butyrate also increased memory function in patients with age-related brain diseases [R].
How Butyrate Improves Memory (Mechanisms)
7) Creatine Improves Memory
Creatine is currently in Phase III clinical trials for the treatment of Huntington’s disease [R].
In elderly patients, creatine supplementation improved cognition and memory in all but one tests, showing that creatine can aid cognitive function in the elderly [R].
How Creatine Improves Memory (Mechanism)
- Creatine is stored as phosphocreatine, which acts as a high-energy reserve. Phosphocreatine decreases rapidly during brain activity. Supplementing with creatine (2 grams per day for 1 month) increased average brain creatine by 9.7%. It acts as an energy source for the brain to focus on learning tasks, as well as an energy source for storing memories.
- Protects against beta-amyloid toxicity in the hippocampus [R].
- Protects neurons by maintaining mitochondrial energy production and protecting the mitochondria (by increasing mitochondrial membrane potential, reducing intra-mitochondrial levels of reactive oxygen species, and reducing calcium inside the mitochondria) [R].
8) Glucose Improves Memory
Studies Show Glucose:
- Improved cognitive functions in subjects with different neurodegenerative diseases [R, R, R].
- Enhanced learning and memory in healthy young animals and humans [R].
- Improved verbal memory associated with conditions [R].

- Increases dopamine (through inhibiting MAO-B) [R, R].
- Acts as an antioxidant and protects against glutamate toxicity [R].
- Inhibits acetylcholinesterase and thus increases acetylcholine [R, R].
14) Modafinil Improves Memory
Adult ADD/ADHD patients given modafinil (200 mg/day) showed significant improvements in short-term memory, visual memory, and spatial planning. However, although they responded more accurately on tests, they had slower responses (DB-RCT) [R].
How Modafinil Improves Memory (Mechanisms)
- Increases glutamate in the thalamus [R].
- Prevents glutamate toxicity [R].
- Increases dopamine, norepinephrine (inhibits dopamine/norepinephrine transporter) and serotonin [R].
- Increases histamine neurons in multiple parts of the brain [R].
15) Armodafinil Improves Memory

18) Coluracetam (BCI-540/Mkc-231) Improves Memory
In rats with brain damage from chemicals, coluracetam reduced the memory impairments with no significant side effects [R].
Coluracetam also displayed long-lasting (72 hours after the last dose) cognitive function improvement after repeated administration [R].
How Coluracetam Improves Memory (Mechanism)
19) Pramiracetam Improves Memory
Pramiracetam is marketed as a treatment for memory and attention deficits in aging people with brain degenerating diseases and vascular dementia.
In males with brain injuries, pramiracetam (400 mg) improved memory with no tolerance over an 18 month period. The effect was sustained even 1 month after discontinuing treatment (DB-CT) [R].
In rats, pramiracetam (7.5 mg/kg and 15 mg/kg) improved long-term memory but did not significantly improve working memory [R].
Pramiracetam was able to partially reduce the memory impairment caused by scopolamine in both young and old (18-42 and 55-65 years) patients [R].
How Pramiracetam Improves Memory (Mechanism)
- Increases nicotinic acetylcholine receptor activity [R].
- Increases choline uptake in rat hippocampus [R].
20) Phenylpiracetam/Phenotropil Improves Memory
