Does supplementing l-arginine have a negative effect on athletes?

  1. Does supplementing l-arginine have a negative effect on athletes?


    I was wondering if taking l arginine as a supp has an effect on athletes? I have recently began taking it and noticed my legs (calves mainly) cramp alot easier and feel more stiff. and yes i stretch. I was just wondering if taking it has any negative effects? thanks


  2. i would tend to think it has a positive effect. i am a baseball player and drink no-shotgun before every game. i have never noticed cramping or any other negative side effect. i have also taken arginine caps and/or drank no-shotgun before playing pickup basketball and again have noticed no negative effects. if you are cramping i would make sure to drink at least a gallon of water a day and drink plenty during your athletic activity.

  3. Cramping? It should not affect cramping in any way, though you might mistake a thick pump for a cramp. You'd have to be working the muscle pretty hard to get that, though.

    There are other issues with arginine, like its effect on creatine in the body, and free-radical formation, that I'm more interested in. Arginine, as a whole, is pretty benign stuff.

    I have not read about it affecting ceatine. Is it a possitive or negative effect?

  5. Possibly negative.

  6. You aren't drinking enough water, maybe you need more electrolytes...
