You only need protien if you dont get enough of it through eating you're normal meals, for example if your a big guy and you want to gain muscle you need alot of it to gain, otherwise all you're really doing is becoming stronger but you wont physically see any difference in you're body.....depending on how much you eat, you can take protein shakes as supplements and theres not really and side affects because all it really is...for example imagine have a piece of chicken in liquid form its got all the same amount of protien in it...also if you want to build muscle and get lean eat TUNA its nothing but protein.
