Optibac's bestselling daily probiotic earns that status for a reason. Every Day EXTRA hits the sweet spot that most athletes are actually looking for: four extensively researched strains, 20 billion CFU guaranteed until expiry, no FOS fiber to trigger GI sensitivity, and a clean four-strain formula collectively studied across approximately 70 clinical trials. It's the daily probiotic for athletes who want more than a generic gut health supplement but don't necessarily need maximum-strength dosing every day. The four strains inside — Lactobacillus acidophilus NCFM®, Lactobacillus paracasei Lpc-37®, Bifidobacterium lactis Bi-07®, and Bifidobacterium lactis Bl-04® — are each among the most documented probiotic strains in clinical literature. Four Strains and ~70 Clinical Trials Behind Them – Every strain in this formula has its own peer-reviewed research portfolio. Together they cover gut bacteria balance, digestive comfort, bloating management, immune support, and post-antibiotic microbiome recovery — the full spectrum of what a serious athlete's daily probiotic should address. FOS-Free and IBS-Friendly – Like Every Day MAX, this formula contains no prebiotic FOS fiber — a deliberate choice that makes it significantly better tolerated for athletes with IBS tendencies, GI sensitivity during training, or anyone who has found high-fiber probiotic blends trigger bloating. The bacteria deliver the benefit without the fermentable fiber that causes discomfort for sensitive systems. What the EXTRA Is All About – Every Day EXTRA adds L. paracasei Lpc-37® and B. lactis Bi-07® to the NCFM® and Bl-04® core found in the MAX formula. That broader strain diversity means wider microbiome coverage — more types of beneficial bacteria supported across different areas of the gut. How to Use Optibac Probiotics Every Day EXTRA Daily Use: Take 1 capsule daily, preferably with breakfast. Can be increased to 2 capsules daily if desired or professionally directed. Post-Antibiotic Recovery: Every Day EXTRA is specifically noted as suitable for replenishing gut bacteria after antibiotic use. Take during and for at least two weeks following a course of antibiotics to support microbiome recovery. How does Every Day EXTRA differ from Every Day MAX? Both share the NCFM® and Bl-04® strains and are FOS-free. Every Day EXTRA adds two additional strains — Lpc-37® and Bi-07® — for broader microbiome coverage at 20 billion CFU. Every Day MAX delivers a higher dose (75 billion CFU) with three strains. EXTRA is the choice for strain diversity; MAX is the choice for maximum dosage.
