BiOptimizers P3-OM Probiotics Review (Probiotic Breakthrough)

BiOptimizers P3-OM Probiotics Review (aka. Probiotic Breakthrough)

Last updated: January 2026

If you’re researching P3-OM Probiotics in the UK, you’ll still find the product sold under this name. However, in some other countries, BiOptimizers now markets the same core formula as Probiotic Breakthrough. This has caused understandable confusion for readers and buyers.

In this updated review, I’ll explain how P3-OM Probiotics and Probiotic Breakthrough relate to one another, what the supplement is designed to do, who it may be suitable for, and whether it’s worth considering if you’re looking to support digestion, gut health, and immune balance.

What Is P3-OM Probiotics (Probiotic Breakthrough)?

Probiotic Breakthrough is an advanced probiotic supplement by BiOptimizers. In the UK and some other regions, it continues to be sold under the P3-OM name. In other international markets, the same product concept is marketed as Probiotic Breakthrough.

Both versions are built around a patented strain of Lactobacillus plantarum OM, often referred to as a “super probiotic” due to its resilience and targeted digestive benefits.

Unlike many traditional probiotics that struggle to survive stomach acid, Probiotic Breakthrough is designed to remain stable as it travels through the digestive tract, helping it reach the gut where it can be most effective.

Important note: While branding may vary by country, the product philosophy and primary probiotic strain remain consistent.

Key Features of P3-OM Probiotics / Probiotic Breakthrough

Why Probiotic Breakthrough Is Different From Regular Probiotics

Most probiotics are about adding “more bacteria” to your gut. Probiotic Breakthrough works a little differently.

The L. plantarum OM strain is often described as proteolytic, meaning it helps break down proteins more efficiently. It’s one reason P3-OM is popular with people who:

• Eat a higher-protein diet
• Feel heavy or bloated after meals
• Want digestive support without refrigeration

It’s also designed to survive stomach acid better than many standard probiotics, so more of it actually makes it to your gut.

Potential Benefits (What People Actually Use It For)

While results vary from person to person, Probiotic Breakthrough may help support:

• Reduced bloating and digestive discomfort
• Improved gut bacteria balance
• Better nutrient absorption
• Immune system support
• Digestive regularity

How P3-OM Probiotics Works

Probiotic Breakthrough focuses on optimizing the gut environment rather than flooding it with dozens of competing bacterial strains. The L. plantarum OM strain is known for its ability to:

• Help break down proteins more efficiently
• Support balanced gut bacteria
• Reduce gas and bloating associated with digestion
• Support immune system function through gut health

By supporting better digestion at the microbial level, this probiotic may also indirectly help with energy levels, mental clarity, and overall well-being.

How to Take P3-OM Probiotics

BiOptimizers recommends taking Probiotic Breakthrough with meals, especially meals that contain protein. This timing helps the probiotic work synergistically with digestion.

Typical guidance:

• Take 1 capsule with a meal
• Can be taken daily
• No refrigeration required

Always follow the manufacturer’s instructions and consult a healthcare professional if you have medical conditions or are taking medication.

About Proteolytic Probiotics?

One thing that makes P3-OM (also known internationally as Probiotic Breakthrough) a bit different from standard probiotics is that it’s often described as proteolytic.

In simple terms, proteolytic means it helps support the breakdown of proteins during digestion.

Most probiotics focus on adding beneficial bacteria to the gut. P3-OM is designed to do that while also supporting digestion, particularly after protein-heavy meals. This is one reason it’s popular with people who eat a higher-protein diet or feel bloated or uncomfortable after eating.

Probiotics in general are live microorganisms that help support a balanced gut environment. When digestion feels off — whether from diet, stress, or lifestyle factors — some people choose probiotics to help support healthier gut bacteria.

With P3-OM, the focus is on helping the digestive process run more smoothly rather than simply adding lots of different bacterial strains. The proteolytic aspect is intended to support protein digestion, which may help reduce that heavy or bloated feeling some people notice after meals.

It’s not designed to treat food intolerances or digestive conditions, but for everyday digestive support, this targeted approach is what many users find appealing.

This protein-focused approach is one of the main reasons people choose P3-OM over generic probiotics — especially if bloating after meals is an issue.

Who Is P3-OM Probiotics Best For?

Probiotic Breakthrough may be a good fit if you:

• Struggle with bloating or digestive discomfort
• Want a targeted probiotic rather than a multi-strain formula
• Eat a high-protein diet
• Prefer shelf-stable supplements
• Have previously used and liked P3-OM Probiotics

It may not be ideal if you’re specifically looking for a broad-spectrum probiotic with many bacterial strains.

BiOptimizers Probiotic Breakthrough Ingredients

Probiotic Breakthrough uses a simple but targeted ingredient profile aimed at supporting digestive balance and gut health:

🍃 Key Active Ingredient

• Lactobacillus plantarum OM (500 mg per serving, ~5 billion CFU) – This is the patented proteolytic probiotic strain that survives stomach acid and reaches the gut where it can work. It’s designed to support protein digestion and help maintain a balanced gut microbiome.

🧠 Supporting Ingredients

• Fructooligosaccharides (FOS) – A prebiotic fibre that helps nourish and feed beneficial bacteria in the gut.
• Stabilized Rice Bran – Provides additional fibre and helps support overall digestive function.
• Vegetable Capsule (plant cellulose and water) – The plant‑based capsule shell that encloses the probiotic and prebiotic blend.

📌 Notes

• CFU stands for Colony Forming Units — a measure of live probiotic cultures. This product delivers about 5 billion CFU per serving.
• The formula is vegan, soy‑free, gluten‑free, and shelf‑stable, so refrigeration isn’t required.

Is P3-OM the Same as Probiotic Breakthrough?

In many respects, yes — P3-OM Probiotics and Probiotic Breakthrough are closely related products sold under different names depending on region.

In the UK, P3-OM remains the active product name. In other countries, BiOptimizers uses the Probiotic Breakthrough branding. This regional naming difference has led to confusion when comparing reviews, labels, and availability.

If you are purchasing in the UK, P3-OM is the correct product name to look for.

Main Advantages of Taking P3-OM / Probiotic Breakthrough

One of the main reasons people are drawn to P3-OM Probiotics is that it’s designed to do more than just add “good bacteria” to the gut.

As mentioned earlier, P3-OM uses a proteolytic probiotic strain, meaning it’s intended to support protein digestion. This can be especially useful for people who feel heavy, bloated, or uncomfortable after meals — particularly protein-rich ones.

Another key advantage is survivability. Many lower-quality probiotics don’t make it past stomach acid, which means they never reach the gut where they’re supposed to work. P3-OM is formulated to be more resilient, increasing the chances that the probiotic actually reaches the digestive tract intact.

Based on how it’s used and discussed, people often choose P3-OM for potential support with:

• Digestive comfort and regularity
• Reduced bloating and gas
• Better tolerance of protein-heavy meals
• Supporting a balanced gut environment

There’s also growing interest in the gut–brain connection, and while P3-OM isn’t a treatment for mood or mental health conditions, many people aim to support overall well-being by improving digestion and gut balance.

By focusing on one targeted strain rather than dozens of competing ones, P3-OM appeals to those who want a simpler, more focused probiotic rather than a generic blend increasing amino acids and help with recovery after intense workout sessions.   By and large, this can help enhance mental clarity, focus and ultimately the immune system.

Side Effects and Safety Warnings

Most people who use P3-OM Probiotics appear to tolerate it well, and it’s commonly taken as part of a daily routine. That said, as with any probiotic, individual experiences can vary.

Some users report mild digestive changes when first starting, such as temporary bloating or an upset stomach. These effects are usually short-lived and often settle as the body adjusts.

P3-OM is made with a relatively simple, targeted formula, which may be one reason many people find it easy to use compared to more complex probiotic blends. However, “natural” doesn’t automatically mean side-effect free for everyone.

Safety notes:

• Not intended for children — keep out of reach
• If you’re pregnant, breastfeeding, or managing a digestive condition, it’s best to check with a healthcare professional first
• If you have an existing stomach condition or concerns, professional advice is recommended before use

As always, following the manufacturer’s instructions and starting slowly can help you see how your body responds.

What Customers are Saying about Probiotic Breakthrough

As with most popular supplements, P3-OM Probiotics has a mix of reviews across different platforms — though the overall feedback tends to lean positive.

On retailer sites and review platforms, many users mention improvements in digestion, reduced bloating, and feeling more comfortable after meals. Some also like the fact that it doesn’t need refrigeration and is easy to take consistently.

There are, of course, a small number of negative reviews. These usually relate to personal expectations, individual results, or issues around ordering and product versions rather than safety concerns. That’s fairly typical for any supplement, as results can vary from person to person.

Overall, the general sentiment around P3-OM is favourable, especially among people who were specifically looking for digestive support rather than a generic probiotic.

If you prefer to do your own research (which is always a good idea), you can also find independent feedback on platforms like Trustpilot and Amazon to get a broader picture before deciding.

Final Verdict: Is Bioptimizers Probiotic Breakthrough Worth It?

P3-OM Probiotics stands out due to its focus on a single, resilient probiotic strain rather than a high-count blend. For those who want digestive support without refrigeration, unnecessary fillers, or dozens of competing strains, it may be a solid option.

For UK readers, P3-OM remains the relevant product name, while Probiotic Breakthrough is best understood as an alternative branding used in other markets. If you’ve seen both names online, they refer to the same probiotic concept rather than two entirely different supplements.

As with all supplements, results depend on diet, lifestyle, and individual gut health.
