Other ·Insufficient evidence ·Reviewed May 2026
Noopept is a synthetic peptide-derived nootropic compound developed and used as a medicine in Russia for some cognitive-disorder contexts. It is not FDA-approved for any indication in the United States, is not a normal dietary nutrient, and English-language human evidence is limited. Supplement use should be treated as experimental and high caution.
The bottom line
Evidence rating insufficient. Most-documented uses: experimental nootropic use for memory consolidation, studied outside the united states for mild cognitive disorders, preclinical neuroprotection and neurotrophin signaling interest. 3 sources indexed (2008–2020), with 3 interaction records on file.
Core mechanism
Noopept is an N-acyl-proline-containing dipeptide analog reported in preclinical studies to influence neurotrophin expression, glutamatergic signaling, oxidative stress, and memory-consolidation pathways. Human evidence is sparse and not adequate to establish efficacy or long-term safety for healthy cognitive enhancement. Its CNS activity and uncertain pharmacokinetics support psychiatric, seizure, cardiovascular, and drug-interaction cautions.1,2
Human pharmacokinetic data for supplement use are limited. Taking with food may reduce nausea, but route, product quality, and dose accuracy are major uncertainties.
Ranked by evidence and value.
Real-world pricing across three quality tiers. Assumes Noopept capsule.
Low price can reflect bulk powder or weak quality controls. Third-party testing and avoiding unapproved-drug blends are critical. Updated 2026-06-04.
Dose: No FDA-approved dose; non-US use often starts at 10 mg/day2,3
Timing: Morning with food
Evidence is insufficient and regulatory status is unfavorable; use should not be routine.
Dose: No FDA-approved dose; non-US use patterns are 10-20 mg/day
Timing: Morning or early afternoon
No FDA-approved dose exists and long-term safety is unknown.
Dose: Avoid stacking initially2
Timing: Not applicable
Adding noopept to complex stacks increases attribution and safety problems.
Where this appears in the symptom-to-supplement map, ranked by relevance.
Proposed neurotrophin and glutamatergic mechanisms are mostly preclinical.1
Seek medical evaluation for progressive memory problems.
CNS-active effects may alter subjective clarity, but evidence is insufficient.3
Risk-benefit is poor for unexplained brain fog.
May affect attention subjectively, but controlled evidence in healthy adults is lacking.
Do not stack with stimulants or unapproved nootropics.
Caffeinated green tea extract can add stimulation, anxiety, insomnia, or palpitations to a CNS-active nootropic.
Recommendation: Use decaffeinated products or avoid the combination if sleep, anxiety, or blood pressure is an issue.
Combining two nootropic products makes headache, dizziness, insomnia, or adverse neurologic effects harder to detect.
Recommendation: Do not start together; avoid in seizure disorder or before surgery.
St. John's Wort can alter drug metabolism and has neuropsychiatric effects; noopept interaction data are lacking.
Recommendation: Avoid combining, especially with psychiatric medications or mood instability.
