You can get all the protein you need from your diet..Tuna, Chicken even peanuts..as Kbox said above you can only process around 30g of protein at at time for an average person...so until you actually pack on some muscle mass, a supplement is not much use to you...personally I would start with adding extra chicken and tuna to my diet and as you begin to work out you body will become more efficient and better able to process proteins, then you can add the supplements.
