Quick answer: L-Arginine and L-Citrulline both feed the nitric oxide pathway, which helps relax blood vessels and supports healthy circulation, oxygen delivery, and nutrient transport throughout the body, including to the brain.
What is L-Arginine?
L-Arginine is an amino acid directly involved in nitric oxide production. VapoCept includes it at 400mg combined across two forms — the base form and an AKG extract.
What is L-Citrulline?
L-Citrulline is converted by the body into L-Arginine, offering a second route to sustained nitric oxide support. VapoCept includes 200mg combined across the HCl and Malate forms.
Why use both?
Combining direct L-Arginine with L-Citrulline (which converts gradually) is generally associated with more sustained circulation support than either ingredient alone.
⚠ Know before you start
Before your first capsule: because these ingredients support the nitric oxide pathway, consult your doctor before use if you take blood pressure or circulation medication.
