Which substances are listed for memory & learning?

12 substances appear in the table, ordered by how often the curated memory & learning stacks use them, then by evidence grade and safety score. The first five are Alpha-GPC (grade A), Bacopa Monnieri (grade A), Omega-3 (DHA/EPA) (grade A), Piracetam (grade A), Lion's Mane (grade B). The order reflects stack usage in this library, not a recommendation.

How strong is the evidence behind them?

Of the 12 listed substances, 9 graded A, 3 graded B. Each grade is the overall grade on that substance's own entry, where its references are listed. Source: How evidence grades are assigned.

Are any of them prescription-only or restricted in the US?

No. Every substance in this table is recorded as over-the-counter or unscheduled in the US. Other countries can differ.

Memory & Learning

Memory benefits emerge over weeks, not minutes. Cholinergic enhancement (Bacopa, Alpha-GPC) and BDNF/NGF support (Lion's Mane, Noopept) are the two most-validated mechanisms. Pair them with adequate sleep and consistent dosing for 8-12 weeks before evaluating.

What the evidence shows

Bacopa Monnieri has the strongest individual evidence base, Stough 2001, Roodenrys 2002, and the Calabrese 2008 meta-analysis all show consistent benefit on memory acquisition and retention at 300-600mg/day after 8-12 weeks. Citicoline (CDP-choline) has well-replicated evidence in stroke recovery (ICTUS trial) and age-related cognitive decline. Huperzine A reliably improves memory in Alzheimer's (Wang 2009 Cochrane review of 6 RCTs) and a smaller signal exists in healthy adults. Lion's Mane has emerging evidence (Mori 2009) with a unique NGF mechanism. Creatine improves working memory under fatigue and sleep deprivation (Rae 2003; McMorris 2006).

How to actually run a protocol

Build a stack around Bacopa (300-600mg daily, with food, indefinitely) plus a choline source (Alpha-GPC 300mg). Add Lion's Mane if you can budget for the dual-extract form (1000-3000mg/day). Add Huperzine A at 100mcg with a strict cycle (2 weeks on / 2 weeks off) for acute amplification. Sleep matters more than any substance, protocols fail when chronic sleep restriction is the actual problem.
