Quick answer: L-citrulline is turned into L-arginine in the kidneys and then into nitric oxide, which helps blood vessels relax. A small trial in men with mild erection problems used 1.5 g a day for a month. It may add to blood pressure medicines, nitrates and ED pills.
How it works
Citrulline avoids much of the breakdown that plain arginine suffers in the gut, so it raises blood arginine more steadily.
What studies found
A small Italian trial reported modest improvements in erection hardness scores at 1.5 g a day; larger studies are lacking. PubMed search.
Gummy reality
1.5 g is a lot for one gummy. Without published doses, expect less.
Cautions
Do not combine with nitrates; ask your doctor if you take ED pills or blood pressure medicine.
