Do prebiotics, probiotics or postbiotics help restore balance to the gut microbiome? I spend a lot of time writing about biomedical sciences, and I have a weird and annoying tendency to develop symptoms of whatever condition I’m looking into. When I was working on a piece about chronic sinusitis, I developed a persistent snuffle. A recent article on hearing loss made me sure I was going deaf. When my subject was snoring, I snored louder and longer than ever.
