Product Description
Most athletes who take a daily probiotic are taking a general-purpose formula built for a general-purpose person. Every Day MAX is built for people who want the most researched strains available at a dosage that actually moves the needle — 75 billion live cultures per capsule, guaranteed until expiry, using three of the most clinically documented strains in the world.
The strain lineup here is the key. Lactobacillus acidophilus NCFM® is considered the most researched strain of acidophilus anywhere — not just one of the most researched, but the most researched.
Alongside it, Bifidobacterium lactis Bl-04® and Bifidobacterium lactis HN019 bring their own extensive clinical trail records, with research specifically covering digestive health, immune markers, and white blood cell activity. All three strains are scientifically proven to survive stomach acid and reach the gut alive. The 75 billion CFU count isn't a marketing number — it's the guaranteed minimum at the end of the product's shelf life, not just at manufacture.
Maximum Strength Formula – 75 billion CFU from three of the most clinically documented probiotic strains available. NCFM® alone has been featured in more published research than virtually any other acidophilus strain on the market. This is the probiotic for athletes who want both volume and evidence behind what they're taking.
FOS-Free — Suitable for Sensitive Guts – Unlike many high-strength probiotics that include prebiotic FOS fiber, Every Day MAX is formulated without it. For athletes prone to bloating, IBS symptoms, or GI sensitivity during training, this makes it significantly more tolerable. The bacteria do the work without the fermentable fiber that triggers discomfort for sensitive digestive systems.
Immune and Gut Health Support – All three strains have been studied in clinical trials for both digestive health outcomes — including occasional bloating and constipation — and immune health markers including immunoglobulin levels and white blood cell activity. For athletes managing heavy training loads that challenge immune function, this is meaningful support.
One capsule daily. Vegan, gluten-free, dairy-free, soy-free. No added sugars, no artificial ingredients, no refrigeration required. Each jar provides a full month's supply.
How to Use Optibac Probiotics Every Day MAX
Daily Use: Take 1 capsule daily, preferably with breakfast. Can be increased to 2 capsules daily if desired or professionally directed.
Timing: Breakfast is recommended as stomach acidity is closer to neutral after eating, improving survival of live cultures. Can be taken with or without food.
Pro Tip: If you're managing active GI sensitivity or transitioning from a lower-strength probiotic, start with 1 capsule daily and assess tolerance before increasing. The FOS-free formula makes this one of the most gut-gentle high-strength options available.

Optibac Probiotics Every Day MAX FAQ's
Everything you need to know about Optibac Probiotics Every Day MAX.
Once daily with breakfast — that's Optibac's specific recommendation, and the reason is practical: stomach acidity is closest to neutral during a meal, which gives the live cultures the best survival environment on the way to the gut. Can be increased to two capsules daily if desired or professionally directed.
Most supplements guarantee their CFU count at manufacture — by the time you take the last capsule, the actual count can be significantly lower. Every Day MAX guarantees 75 billion until the end of the product's expiry date. That's the minimum you're getting on day 30, not just day one.
NCFM is the most researched strain of acidophilus in the world — not just one of the top strains, but the single most documented. It's been the subject of more published clinical research than virtually any other acidophilus strain, covering digestive health outcomes, immune markers, and gut barrier function. When a supplement description says "clinically researched strains," NCFM is what that actually looks like in practice.
Yes — all three strains have clinical research covering both. B. lactis Bl-04 and HN019 have been specifically studied for immune markers including immunoglobulin levels and white blood cell activity. For athletes managing heavy training loads that chronically challenge immune function, that research is directly relevant — this isn't just a gut supplement that also mentions immunity on the label.
It's one of the most GI-friendly high-strength options available precisely because it's FOS-free. Optibac specifically notes it may be suitable for those with IBS. If you're managing active GI sensitivity or transitioning from a lower-strength probiotic, start at one capsule daily and assess tolerance before increasing.
