Neurapezil names all 6 of its ingredients, which is genuinely good. But once you look at what they are, a clear pattern emerges — and it changes how you should read the “memory” claims.
L-Arginine, L-Arginine AKG, L-Citrulline HCL and L-Citrulline Malate all feed the nitric-oxide pathway that widens blood vessels. That’s four of the six ingredients doing essentially the same job: vasodilation. The remaining two are Niacin (a vitamin) and Beta-Alanine (a sports-nutrition amino).
This is a circulation stack — the kind of thing sold for exercise “pumps” — repositioned for the brain. The logic is that more cerebral blood flow supports brain function. It’s plausible, but it’s not the classic evidence-backed memory line-up (Bacopa, Lion’s Mane, Ginkgo, phosphatidylserine), and strong proof that arginine/citrulline improve memory in healthy people is limited.
