What fiber supplement for bloating and digestion that works for you?

I have been dealing with on and off bloating after meals and I'm trying to figure out if a fiber supplement would actually help with digestion or just make things worse. I've seen a lot of mixed takes online so I figured to just ask people who've actually tried stuff.

My diet isn't terrible but I probably don't hit the fiber intake I should daily. Just looking for something that doesn't wreck my stomach in the process. I heard psyllium can be hit or miss for some people so I'm a little hesitant.

What fiber supplement have you stuck with and noticed a difference? Did it take a while before your gut adjusted or was it pretty smooth from the start?
