Most people do not need to take extra arginine. While some people with serious infections, burns, or other trauma should take arginine, appropriate amounts must be determined by a doctor. Levels used in research vary considerably (2–30 grams per day). Most research on cardiovascular disease has used between 6 and 20 grams per day. Optimal intakes remain unknown and are likely to vary depending upon the individual.
Dairy, meat and poultry, and fish are good sources of arginine. Nuts and chocolate also contain significant amounts of this amino acid.
