Aniracetam

Aniracetam is a fat-soluble pyrrolidinone racetam that acts as a positive allosteric modulator of AMPA receptors, slowing desensitization and enhancing synaptic plasticity in hippocampal CA1 and dentate gyrus regions. One open-label study (n=276) showed maintained cognition at 12 months and improved emotional state vs cholinesterase inhibitors in mild dementia. Prescribed in Greece/Italy for cognitive disorders. Withdrawn from Japan after failed placebo-controlled trial. Not FDA-approved in US.

Related Supplements

Vitamin E

1 shared condition · 274 outcomes

Vitamin E is a fat-soluble antioxidant that protects cells from oxidative damage and is found in several common foods. Supplementing with extra vitamin E does not have broad health benefits, except in people with vitamin E deficiency, and long-term high-dose supplementation may cause harm.

Piracetam

1 shared condition · 15 outcomes

Piracetam is the parent compound of the racetam class of nootropic supplements. When supplemented, it provides a mild boost to brain function.

Phosphatidylserine

1 shared condition · 73 outcomes

Phosphatidylserine (PS) is an amino acid derivative that is fat soluble and found in high amounts in the brain, where it contributes to cognitive functioning. PS has been studied the most for cognition in adults over 50, for people with high chronic stress, and for exercise performance, but further research is needed to confirm any benefit.

Phlebodium aureum

1 shared condition · 9 outcomes

Polypodium Leucotomos (Calaguala) is the commonly referred to name of a herb that appears to possess moderately potent protective effects against sun-induced skin damage; may also be an immune booster.

Oxiracetam

1 shared condition · 10 outcomes

Oxiracetam is one of the three first-tier racetam compounds, being produced after both Piracetam and Aniracetam. Oxiracetam appears to enhance the release of excitatory neurotransmitters and can aid in memory formation, but lacks human studies.

Kanna

1 shared condition · 28 outcomes

Kanna is a South African succulent with unique dual mechanism: serotonin reuptake inhibition (SSRI-like) + PDE4 inhibition. Active alkaloids include mesembrine, mesembrenone, mesembrenol. Brain imaging shows reduced amygdala reactivity to threat (anxiolytic mechanism). Small trials show cognitive/mood benefits. CRITICAL: Do NOT combine with SSRIs, SNRIs, or MAOIs - serotonin syndrome risk. Not addictive. Standardized extract (Zembrin) used at 25mg daily.

Ginkgo Biloba

1 shared condition · 173 outcomes

Ginkgo biloba is the most commonly ingested herb for brain health. While it may boost cognition in older populations, this effect is not very reliable or generalizable.

Alpha-Lipoic Acid

1 shared condition · 40 outcomes

Alpha-lipoic acid (ALA) is an endogenous antioxidant involved in mitochondrial energy metabolism. Notable: Most evidence is C-grade or D-grade despite popularity. Best evidence is for diabetic neuropathy (IV administration - prescription in Germany), blood flow improvement, and inflammation reduction in RA. Often combined with L-carnitine. R-ALA is the biologically active form; supplements often contain racemic (R+S) mixture. Effects are short-lived due to rapid metabolism. May cause mild hypoglycemia.
