glutamine question

[njlw226]

guys, i just purchased glutamine powder of opti nutrition. one question though. im currently taking this with my post workout shake on workout days. do i need to take it on my off days? i work out 4 days a week, the other 3 days i just do cardio for 30 minutes. basically, do i need to be taking it every day like creatine? thanks.

ya take it a few times a day. post workout and right before bed is good too
