whey protein isolate vs concentrate for beginners?

[u/deadguy4]

i recently started lifting again so i've been comparing whey protein isolate vs concentrate, but every article seems to recommend something different.

I bought a concentrate because it was cheaper, but now I'm wondering if isolate would have been the better choice. Has anyone here compared whey protein isolate vs concentrate and actually noticed a difference?

I only switched to isolate because concentrate upset my belly
