Product Description
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.

Optibac Probiotics Every Day EXTRA FAQ's
Everything you need to know about Optibac Probiotics Every Day EXTRA.
One capsule daily with breakfast — stomach acidity is closest to neutral during a meal, which gives the live cultures the best chance of surviving the journey to the gut. Can be increased to two capsules daily if desired or professionally directed. For anyone who can't swallow capsules, the contents can be opened and mixed into cool non-acidic food or drink.
It means 20 billion live cultures guaranteed until the end of the product's expiry date — not just at manufacture. By the time you take the last capsule, you're still getting the full dose. That's the standard Optibac holds across their range and it's the number that matters, not what's printed at the point of production.
L. acidophilus NCFM is the most researched acidophilus strain in the world, covering digestive comfort and immune support. L. paracasei Lpc-37 adds coverage for gut bacteria balance and immune function. B. lactis Bi-07 has strong clinical research for bloating reduction and immune markers. B. lactis Bl-04 rounds out the formula with research on immune health and post-antibiotic microbiome recovery. Together across approximately 70 clinical trials they cover the full spectrum of what a daily athlete probiotic should do.
FOS is a fermentable prebiotic fiber that feeds gut bacteria but also triggers bloating and gas in people with IBS or GI sensitivity. Optibac deliberately formulated Every Day EXTRA without it — the four strains deliver the benefit without the fermentable fiber that causes discomfort for sensitive systems. For athletes managing GI sensitivity during training, this is a meaningful distinction from most multi-strain probiotics on the market.
Both share NCFM and Bl-04 and are FOS-free. EXTRA adds Lpc-37 and Bi-07 for four-strain coverage at 20 billion CFU — the wider strain diversity gives broader microbiome coverage across different areas of the gut. MAX delivers a higher dose at 75 billion CFU with three strains. Choose EXTRA for strain diversity as your daily foundation; choose MAX if you want maximum dosage intensity.
