there is "no whey" that this added protein alone will build muscle. extra protein -- above and beyond his nutritional needs -- has the potential of overloading his kidneys especially if he is sweating and exercising and not getting in sufficient water. all he needs to do is eat a good balanced diet (three meals and some healthy snacks) work out regularly (no power lifting weights! ) and he will get stronger. and leaner. he does not need "something stronger" like those bulk-builders at the health food stores.
at what age is it appropriate to use whey protein in weight training? . my grandson is almost 14 and has started weight training at school for football. he believes that whey protein will improve his muscular strength more rapidly. is it safe at his age to use these products or should he just continue with a balanced diet with added foods containing protein? will he be at greater risk of trying something stronger if the whey protein doesn't have some positive effect for him?
