What does the data say about Bio-Kult Advanced Multi-Strain vs Optibac Probiotics Every Day?
Both probiotics score equally at 80/100 and share identical effectiveness and ingredient quality ratings, which makes the choice come down to practical differences rather than performance. Bio-Kult Advanced Multi-Strain contains 14 bacterial strains at 2 billion CFU per capsule, meaning you'll need 2–4 capsules daily to reach a meaningful dose, at £16.95. Optibac Every Day uses fewer but more clinically documented strains — NCFM, HN019, and Rosell-11 — at 5 billion CFU in a single capsule, for £13.99. Optibac's value score of 70/100 edges ahead of Bio-Kult's 60/100, largely reflecting that lower price and simpler dosing.
Bio-Kult is the better pick if you're specifically taking antibiotics or dealing with candida issues — users consistently report it prevents thrush and microbiome disruption during antibiotic courses. Optibac suits people with ongoing digestive discomfort, bloating, or dietary restrictions, as it's vegan, gluten-free, and dairy-free, and the once-daily convenience is genuinely easier to stick to long term.
Both are third-party tested and come in capsule form. Bio-Kult's multi-capsule dosing means you'll get through a bottle faster, which adds to its higher running cost. If budget matters, Optibac is the more economical option day-to-day.
Bio-Kult Advanced is a 14-strain probiotic supplement delivering 2 billion CFU per capsule (up to 10 billion at maximum dose), widely recommended by UK healthcare professionals.
