What does the data say about Advanced Multi-Billion... vs Optibac Probiotics Every Day?
Both Solgar's Advanced Multi-Billion Dophilus and Optibac's Every Day capsules share the same 5 billion CFU per serving, so neither wins on raw numbers. The real difference is in strain selection. Solgar uses four premium branded strains — LA-5®, BB-12®, LGG®, and L. casei 431® — each with substantial clinical trial backing. Optibac uses NCFM, HN019, and Rosell-11, which are also well-researched, though Solgar's roster is arguably more prestigious in the literature. Optibac is third-party tested; Solgar is not, which matters if you want independent verification of what's actually in the capsule.
At £25.49 versus £13.99, Solgar costs nearly double. Given that both score similarly overall — 82 versus 80 — the price gap is hard to justify on performance alone. Solgar earns slightly higher marks for ingredient quality (88 versus 80), which reflects those branded strains. Optibac scores higher on effectiveness (90 versus 83), suggesting users feel the results more noticeably day-to-day. If budget is a real concern, Optibac delivers comparable gut health benefits at nearly half the price.
Both products are vegan and free from dairy and gluten, so allergen-wise they're broadly equivalent. Optibac's single daily capsule is convenient and well-suited to anyone building a simple supplement habit. Solgar suits those who specifically want those branded strains — particularly LGG® and BB-12®, which have strong evidence for post-antibiotic recovery — and are willing to pay the premium for that reassurance. For most people, Optibac is the more practical, better-value pick.
Solgar Advanced Multi-Billion Dophilus is a multi-strain probiotic supplement delivering 5 billion CFU per capsule across four clinically researched strains: Lactobacillus acidophilus (LA-5®), Bifidobacterium lactis (BB-12®), Lactobacillus paracasei (L.
