I've been reading about protein shakes, it's benefits and side effects. However i've used it many times as my post workout recovery drink.
I have no doubt in the benefits i get in my protein shake, i gained mass ( i was a skinny guy back then) , and i'm not talking about fat mass, i gained muscle, Now i've read that protein shakes actually damage the kidneys and the liver since the body cannot synthesize the protein very well.
This article i've read says it damages the kidney and liver:
But other articles suggest that protein only damages more those persons who have already pre-damaged their kidneys, in other words it only worsens it , but does not cause the damage itself.
Because of conflicts in what i should believe in. I'd like to ask from you, who have experienced drinking protein shakes, probably long term or short term. How true are these side effects? And can you mention how long have you been taking protein shakes?and your experiences on this. Thanks!
