Quick answer: L-citrulline raises arginine and nitric oxide; a small trial in men with mild erection problems found modest benefits at 1.5 g a day. Pine bark extract studies report better blood vessel function, often combined with arginine. Both can lower blood pressure.
L-citrulline
Found in watermelon, citrulline raises nitric oxide more reliably than arginine itself. Small studies suggest modest improvements in erection hardness in mild cases.
Pine bark extract
A branded French maritime pine bark extract has been studied for blood vessel function, blood pressure and, combined with arginine, erectile scores.
Cautions
- Both may lower blood pressure, especially with nitrates or ED pills.
- Pine bark may add to blood thinners.
