The three most-researched compounds
Bacopa Monnieri, Phosphatidylserine, and Huperzine A each have a substantial body of published research tied to memory and cognitive function. See our full Bacopa Monnieri deep dive, Phosphatidylserine article, and Huperzine A article.
DMAE and N-Acetyl L-Tyrosine: focus support
Both compounds have research tied to neurotransmitter production and cognitive focus. See our DMAE and Tyrosine article.
The proprietary blend transparency gap
Neurapezil's label discloses all 19 compound names and the combined blend weight (661mg), but not individual per-ingredient doses — standard practice for proprietary blends, but a genuine limitation when comparing the formula to clinical literature that specifies exact doses used in studies.
The full B-vitamin panel
Unlike many nootropic formulas, Neurapezil discloses a complete 21-micronutrient vitamin and mineral panel with exact amounts and %DV, including notably high levels of B6 (735% DV) and B12 (375% DV), both tied to nervous system function.
Bottom line
Neurapezil's formula reflects a reasonably transparent approach for a proprietary-blend product, naming all compounds even without individual doses, and pairing well-researched nootropics with a genuinely comprehensive B-vitamin panel. See our overall worth-it review for the full picture.
