Arginine & Citrulline
L-Arginine and L-Citrulline are two of Memo Vance Pro's seven named ingredients, and they're more often seen in sports-nutrition products than in traditional "brain supplements." Here's an honest look at both.
L-Arginine
An amino acid that serves as the substrate for nitric oxide production in blood vessel walls, a process tied to vascular tone and blood flow regulation. A 2022 trial in frail, hypertensive older adults found improved cognitive assessment scores after four weeks of supplementation, with endothelial function proposed as the mechanism.
L-Citrulline
Functions as a precursor to L-Arginine in the body, and is more extensively studied in exercise performance and blood pressure research than in cognition specifically.
An Honest Note On The Research
The cited L-Arginine trial tested plain L-Arginine, not this finished product, in a specific population (frail, hypertensive older adults) at a dose that isn't stated in directly comparable terms to this label. This research is relevant background, but it does not establish that Memo Vance Pro improves memory, focus, or cognitive performance in general healthy adults.
