My 15 yo son is a keen footballer and in the last year has started going to the gym. He is NOT doing massive weights or anything, in fact the gym has an e-gym which sets the machines according to his age/weight/ability/training programme (he's chosen athletic) with some cardio and a bit in the weights room.
He has done lots of reading and spends a lot of time being influenced by social media.
I am really struggling to make my own informed decision because there is SO much information out there.
My instinct is that most people should be able to get what they need from their diet (I have been a keen and competitive runner since way before the days gels and sports drinks were around and when fuel was called food and hydration was called drink!) and that children really shouldn't need supplements.
I'm OK with him doing it if it's safe i.e I want to support what's important to him.
Can anyone advise or point me somewhere with unbiased studies?
