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
Gut health is where blends are sold hardest and where the single ingredients are easiest to judge one at a time.
Why these
Combocillus Probiotic Powder: Multi strain probiotic capsules at 10 billion CFU; the benefit in trials shows up over about four weeks.
Lactobacillus Rhamnosus Powder: One well-researched strain as a powder, dosed by the scoop.
Enzymase Digestive Enzyme Complex: Digestive enzymes taken with meals.
Colon Support Formula Capsules: Prebiotic fibre with a probiotic blend, increased gradually.
L-Glutamine Capsules: L-glutamine, the amino acid most used by the gut lining.
Magnesium Citrate: For regularity; the bowel effect arrives within a day.
What to skip
Anything called a cleanse or a detox. Persistent bloating, a change in bowel habit, or blood in the stool needs a GP, not a supplement.

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.
