You can buy a range of L Arginine supplements, either at the drug store or at a health food store.
GNC or The Vitamin Shoppe sell them online, as do many others.
I like NoX 3000 or Nitruline , but there are a host of brands out there.
DO NOT FORGET TO DRINK A LOT OF WATER when taking these supplements.
Drinking more water on its own will improve your load a bit, anyway.
If you are wondering what sorts of foods contain Arginine naturally: peanuts (and peanut butter) are high in it, as are a variety of other nuts. Shellfish: crab, shrimp, oysters… Spinach has some.
Google is your friend.
