Help him poop

Noodle has chronically had weird stool. The past few months he’s been getting constipated more usual that before so my vet prescribed lactulose when he needs extra help. He will usually have a massive hard bowel movement like every 38 hours or so. I have tried proviable probiotics and adding extra water to his meal toppers but wondering if there’s any good supplements or additives that could possibly help. I also recently started adding laxatone the hairball paste that I haven’t noticed a difference just yet.
