Coles has Tonik's Prebiotic (PrecticX) Capsules for $16.25 today, knocked down from the regular $65.00, so you're saving $48.75 a pack. Tonik is an Australian brand and this one uses PrecticX, a research-backed prebiotic fibre ingredient that feeds the good bacteria already in your gut rather than adding new ones. If you've been meaning to try a prebiotic but baulked at the usual price tag, this is a good moment to throw one in the trolley. Stock at this price won't hang around.
