Memodyne's four amino acids -- L-Arginine, L-Arginine AKG, L-Citrulline HCl, and L-Citrulline Malate -- are all connected to one shared biological pathway.
Arginine and citrulline are both amino acids the body can use in producing nitric oxide, a molecule involved in relaxing and widening blood vessels.
Cognitive function relies on a steady blood supply reaching the brain. Formulas built around circulation-support amino acids are typically positioned on that basis.
Most published research on arginine and citrulline looks at these ingredients individually, often at doses used in exercise or vascular research, rather than testing Memodyne's specific finished formula.
