Probiotic (Multi-strain) vs Psyllium Husk
Probiotic vs prebiotic fiber: which for gut health?
The verdict
Fiber first. Most people don't need a probiotic if fiber and diet diversity are handled.
Fiber is what your existing gut bacteria eat. Probiotic strains often don't colonize long-term — they pass through. Feeding the microbes you already have usually beats adding new ones.
