I can't really say if supplements help or not, honestly. However, based on personal experience, I think everyone should at least consider a multi, fiber, and protein. I say consider because I totally agree that eating actual food is better than taking some supplements.

One thing I think most people fail to realize is that supplements and bogus claims are nothing new to this world. I know in the wild west-era of America, they had people going town to town in carts selling people bogus items. Some of these things can actually kill people while other times it's just flat out weird (stuff like goat balls or something). I think overall, looking at the big picture, at least we're kind of safe in modern times - by that I mean if some supplement actually killed someone or harm you, you would at least have the resources to research it if you want.
