Probiotics

A probiotic supplement contains live bacterial cultures, most often named Lactobacillus or Bifidobacterium strains, sold as capsules, powders or gummies. A prebiotic is a different ingredient — a specific plant fibre such as FOS or inulin — which some probiotic products include on the same label as a combined formula. Check the ingredient list to see whether a product contains live cultures, fibre, or both.

It depends on the specific product: some probiotic supplements are freeze-dried and labelled shelf-stable at room temperature, while others need refrigeration so the labelled CFU count stays accurate until the best-before date. Always follow the storage instructions printed on your product's own packaging, since this differs by brand and strain.

There is no single timing that applies to every product — manufacturers set their own directions based on the specific strains and capsule coating used. Check your product's label for the recommended serving size and timing, and if you take other medication, ask a pharmacist how to time it.
