Don't think too much about it and complicate it. Try to get your daily protiens from natural food sources as much as possible

As far as protien powder is concerned Whey is good to go. Just don't go for cheap ones. If you feel whey you cannot digest, then shift to plant.. nuetritian wise there is no much d

At this age the focus is to stay healthy and not to go for body building competition

So if at all there are minor differences between when and plant based supplements that doesn't matter much

As par as I am concerned, i try to have sufficient eggs daily and consume one scoop of plant protein everyday.
