I have some L-Citrulline from Source Naturals too, but it is in capsule form, 500 mg each, so I will start taking 2. (They're not too big) Dr. Ignarro suggests 2-3000 mg of L-Arginine twice a day, and that seems like a lot. I'll wait and see how I do without adding it. I did notice that iHerb had a combination pill of both, but wasn't sure about it since the dosage was different.

Thanks again for your response.
