Quick answer: L-arginine is a building block for nitric oxide; studies in mild erection problems used several grams a day, often with pine bark. Cnidium's compound osthole relaxes smooth muscle in lab studies, but human trials are lacking.
L-arginine
Some trials found modest improvements in mild erectile dysfunction at 1.5 to 5 g a day. It is partly broken down in the gut, which is why citrulline is sometimes preferred.
Cnidium monnieri
Used in traditional Chinese medicine. Lab and animal studies suggest effects on smooth muscle; there are no solid human trials.
Cautions
- Arginine with nitrates or ED pills may drop blood pressure too far.
- Arginine is not advised after a recent heart attack.
- Cnidium has rare liver injury reports.
