Research shows that L-citrulline works better then L-arginine as L-arginine taken orally looses effect while L-citrulline is converted into L-arginine inside your body:) but if you want L-arginine Im sure this product is perfect.

L'Arginine has been used for some years in conjunction with prescribed cardiac medications. The Now product is always of consistent quality and we have now experienced the fastest and most reliable delivery service from iHerb. We will continue to use iHerb as a reliable supplier.

I had lost the ability to have a sustained erection due to blood pressure medication. After taking two tablets a day for 2weeks, all erectile problems have gone, I'm sleeping better and my mood is calm. Fantastic results
