I smoke and have been having cramps when I walk. My doctor says I should try arginine. What do you think?

Well, my advice is stop smoking. It is an unhealthy habit. If you do not stop smoking, then nothing will help you. You may try arginine, but you also need to eat healthy, exercise and reduce your weight.

Some studies show that smokers with peripheral vascular disease do benefit from arginine supplements. It is not known if the benefits are sustained.
