In my anatomy class i take (my major is neurosurgeon) ive learned that your body only uses a certain amount of protein, therefore, only needs a certain amount of protein. The only way to build bigger muscles is to excercise them. All these companies selling proten shakes to people the consume 200g (example) of protein daily are making money off a misconception. As a matter of fact its not even recommended you take vitamins often those pills give you too big of a dose to consume on a daily basis. The only vitamins that are safe to take daily are water soluble ones because excess amounts are lost in urine, these include vitamin C and all vitamin B
