What actually works for bad breath?

I've been struggling with bad breath for a while now, and it’s starting to get frustrating. I brush, floss, and use mouthwash religiously, but sometimes it still feels like nothing works long-term. I’ve read that bad breath can be caused by more than just oral hygiene—things like digestive issues, diet, and even pH imbalances might play a role.

I’m looking into different solutions that go beyond just mints and mouthwash. Some people recommend probiotics, others swear by certain supplements that support digestion and throat health. Has anyone here found something that truly works for them? Would love to hear your experiences!
