Do I need a probiotic or a prebiotic?
Probiotics are the bacteria; prebiotics are the fibre that feeds them. Many products combine both, and plenty of people take a live culture alongside simply eating more plants.
Do probiotics need refrigerating?
Some do, some are shelf-stable, and the pack is explicit. Shelf-stable does not mean lower quality - it reflects the strain and how it was dried.
How long before I notice anything?
Manufacturers generally suggest a few weeks of daily use. It is cumulative rather than something you judge after a couple of days.
Can I take them with antibiotics?
Many people do, spacing them a few hours apart and continuing after the course. Your pharmacist can advise on timing for the specific antibiotic.
