Supplements for gut health
Probiotics, digestive enzymes, prebiotic fibre, L-glutamine and magnesium citrate: what each is for and how long the trials took.
How to choose a gut health supplement
A calmer, more comfortable gut: less bloating, better digestion and regularity you can rely on. Probiotics restore balance, enzymes help you digest meals, fibre keeps you regular and feeds good bacteria, and glutamine nourishes the gut lining. Choose by the symptom that bothers you most.

Common questions
How long do probiotics take to work?
It depends on why you are taking them. Alongside antibiotics the benefit shows during the course; for general gut symptoms the trials mostly measured at four weeks or more.
Should I take digestive enzymes with every meal?
They are taken with the meals that cause trouble, not every meal. The label gives the directions.
Do I need a probiotic and a prebiotic?
Not necessarily. Prebiotic fibre feeds the bacteria you already have; a probiotic adds specific strains. Many people start with one and judge over a month.
