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