This formula's own materials describe L-Citrulline converting to L-Arginine specifically in the kidneys — worth understanding why that detail matters if you have any kidney-related concern.
Since L-Citrulline's conversion to L-Arginine happens in the kidneys specifically, rather than the gut or liver, this pathway depends on normal kidney function to work as intended.
If you have any diagnosed kidney condition or reduced kidney function, this specific mechanism detail is worth raising directly with your doctor before starting, rather than assuming it's a general, universally low-risk ingredient.
The 3-bottle package is our suggested starting point — backed by the 60-day money-back guarantee.
