for Digestive Health, 30 Capsules | 6 Scientifically Researched Strains with 5 Billion Live Cultures | Gluten Free & Vegetarian | Supports Gut Flora & Digestive Health

For years, I struggled with fatigue, digestive issues, and overall poor health—despite my efforts to eat well. Over the course of my lifetime, I’ve taken a plethora of antibiotics to fight various infections. While they were effective in treating those infections, they also caused significant damage to my gut flora. As a result, at a certain point my gut biome had been so badly damaged that even healthy food couldn’t be properly assimilated. Worse, the food I ate would rot in my gut, leading to foul-smelling gas and barely-passable, pencil-thin bowel movements. My gut was in a constant state of dysfunction, and I felt utterly drained. I tried many other highly advertised single strain doctor recommended probiotics with varying less than optimal RESULTS. That’s when I decided to do a deeper dive to research and came upon the OPTIBAC probiotic formula. Within just four days of taking them, I began to feel a noticeable boost in my energy levels. My bowel movements became more normal, and I no longer felt like my digestive system was in turmoil. My understanding of what these probiotics do is they help establish temporary colonies of healthy bacteria in the gut. These new bacteria provide support to the remaining beneficial bacteria, helping them recover and rebuild. The proof of their effectiveness is clear—not only did my bowel movements improve, but started to feel energy again. I imagine they were helping my body to properly digest, break down, and synthesize the nutrients from my food. It’s a small but powerful transformation. While they’re a bit pricey, the results are more than worth the investment. If you’re dealing with similar digestive issues, I highly recommend giving this product a try.

Perfect! Works as promised!!

I love it

Helps my IBS!

Opitbac has never failed me! Once taken how directed, it works EXACTLY how it should. No bloating, just good vibes for the stomach and digestive tract. I would HIGHLY recommend for anyone who's having a hard time eating certain foods (gut wise). Shipping was fast as well!

Best Probiotic Ever! ( or at least for Me🤭😁) A Probiotic that can be taken ,by People on Antibiotics whether short or long term use.🎉

We had been using a brand sold in Costco but it was not helping my husband. He has used this product for a month and feels better.

Didn’t help me

Do the job.

Ich habe diverse Allergien und Unverträglichkeiten (Laktose, Fructose, Histamin) seit meiner Kindheit. Eigentlich weiß ich was ich essen darf/kann, aber gerade im Restaurant/bei Einladungen/Zeiten wie z.B. Weihnachten ist das nicht immer so einfach. Auf andere (auch sehr gut bewertete) Probiotika habe ich mit starken Bauschmerzen/Blähungen reagiert. Im Internet habe ich dann gelesen, dass es Probiotika gibt, bei denen bestimmte Bakterienstämme Histamin produzieren und das erklährt meine starken Reaktionen darauf. OptiBac dagegen ist einfach super: keine Durchfälle mehr, wenn ich es in solchen Situationen vorbeugend nehme (Morgens und Abends je eine Tablette), schnelle Hilfe wenn der Bauch doch einmal durcheinander gerät, bessere Verträglichkeit von Produkten, bei denen ich sonst schon auf kleinste Mengen reagiere und keine Nebenwirkungen. Ich kann es uneingeschränkt empfehlen!

Gutes Produkt. Meine Mutter nimmt das täglich. Ihr hilft es.

In 2025 my 86-year-old mother survived a massive heart attack. As a result she’s on 10 tablets a day which cause havoc to her system. Prior to the attack she also had gastric issues and was on a well-known brand for this almost daily. It would cause her painful bloating and other issues. She was also getting bad diahorrea from time to time and was quite miserable overall. While she was recovering I noted that she seemed to tolerate yoghurt really well and found Optibac, checking that there were no issues with her heart medications. I told her to take them for at least a week, warning that she might have early side effects but to push through those. The results: She ‘s just finished taking them for a month. She mentioned that the diahorrea has pretty much stopped and that she no longer gets the painful bloating that was a regular part of her life. She also mentioned that she feels ‘better in herself’. She seems to have more stamina and energy too. This is a brilliant result for her and I’m glad to have found these. She’ll be taking them regularly from now on. VERY highly recommended.

Purchased mainly for my wife, who has taking this brand of probiotic’s for more than 3 years now. Claim is effective for her.
