Fortiflora vs. Proviable: Which is Right for Your Pet? Experts Weigh In

As a pet parent, ensuring your furry friend stays healthy can sometimes feel like navigating a maze, especially when faced with seemingly similar products like Fortiflora and Proviable. Both probiotics are popular choices for improving gut health in pets, but how do they compare, and which one is best for your pet’s specific needs?

Key Takeaways:

  • What’s the main difference between Fortiflora and Proviable? Fortiflora is a single-strain probiotic, while Proviable is multi-strain, offering a broader spectrum of benefits.
  • Which product is better for acute digestive issues? Fortiflora may work faster for short-term, sudden issues.
  • What about long-term gut health? Proviable tends to be more beneficial for chronic or ongoing gut health management due to its diversity of strains.
  • How about ingredients and safety? Both are generally safe, but Proviable’s inclusion of prebiotics may offer a slight advantage for fostering good bacteria.

🤔 What’s the key difference between Fortiflora and Proviable?

It’s all about the strains.

Fortiflora contains one primary strain of beneficial bacteria: Enterococcus faecium. This singular focus allows it to target acute digestive issues, such as diarrhea, quickly. On the other hand, Proviable contains seven different strains of bacteria, including Enterococcus faecium but also others like Lactobacillus acidophilus and Bifidobacterium bifidum. This multi-strain composition can be more effective for long-term gut health and pets with recurring digestive problems.

ProviableMulti-strain Probiotic + PrebioticsLong-term gut health & chronic issues

⏳ Which one works faster for immediate digestive relief?

When your pet has sudden diarrhea or an upset stomach, you want quick resultsFortiflora has a reputation for working quickly due to its single-strain approach, which can take immediate action against harmful bacteria. However, Proviable might take a bit longer because it works by repopulating the gut with a broader range of good bacteria, addressing deeper issues.

So, if you’re dealing with something like a stress-induced upset stomach (e.g., after travel), Fortiflora might be your go-to for rapid relief. But if your pet has ongoing digestive sensitivity or issues, Proviable’s multi-strain benefit may offer sustainable relief over time.

🧬 How do the additional ingredients impact your pet?

Another critical difference lies in what else is in the formula besides probiotics. Proviable includes prebiotics, which essentially feed the good bacteria and help them thrive once they reach the gut. Prebiotics can give an added boost to your pet’s overall digestive environment, ensuring the good bacteria stick around longer and do their job more effectively. In contrast, Fortiflora focuses solely on probiotics without prebiotics.

However, prebiotics aren’t always necessary for every pet, especially if you’re only trying to correct a temporary issue. But for long-term maintenance, Proviable’s formula may help create a more balanced, sustainable digestive system for your pet.


🐶 Which one is better for pets with chronic digestive issues?

If your pet is prone to recurring issues, like IBD or chronic diarrheaProviable often emerges as the stronger candidate. Its combination of multiple strains and the inclusion of prebiotics can help build a more resilient digestive system over time.

On the other hand, Fortiflora excels in short-term solutions but might not provide enough diversity to combat ongoing or complex digestive issues effectively. So, if you’re looking for long-term gut health management, Proviable may be your best bet.

💡 Is there a significant difference in safety and side effects?

Both Fortiflora and Proviable are generally regarded as safe for most pets, including both dogs and cats. Neither product has a notable track record of adverse reactions, but it’s always good to check with your vet, especially if your pet has underlying health conditions.

However, some pets might react differently to a single strain versus multiple strains. Proviable’s prebiotics can also occasionally cause mild gas or bloating in certain animals as the gut flora balance is restored.

If your pet has had digestive issues before with supplements, starting with Fortiflora might be a better option, as its singular focus is less likely to cause unintended side effects.

Final Key Takeaways:

  • Fortiflora is ideal for quick fixes, while Proviable is better for chronic care.
  • Proviable offers more comprehensive digestive support with its multi-strain formula and prebiotics.
  • Consult your vet to tailor the probiotic choice based on your pet’s specific needs.

Understanding the difference between these probiotics can ensure your pet receives the care they need, whether it’s a one-off upset stomach or long-term digestive management.


Comment 1: “Can I give both Fortiflora and Proviable together?”

Absolutely! You can technically give both Fortiflora and Proviable at the same time, as they serve complementary functions. However, there’s no strong evidence suggesting that using both simultaneously provides significantly greater benefits than using one. In fact, using both together might not allow you to determine which product is actually helping your pet if issues arise or improvements are seen.

Fortiflora, being a single-strain probiotic, can deliver a concentrated dose of beneficial bacteria that may work quickly for short-term relief. Meanwhile, Proviable offers a broader approach with its multi-strain composition and prebiotics, supporting longer-term gut health.

The key question to consider is why you’d want to use both. If your pet is dealing with a sudden digestive upset, using Fortiflora might give quicker results, while Proviable can work in the background to stabilize the gut over the long term. If your vet recommends using both, it may be for specific reasons like needing immediate relief along with ongoing gut support.

However, always check with your vet before starting both, as too many probiotics could potentially disrupt your pet’s digestive balance rather than help it.


Comment 2: “Is one probiotic better for cats versus dogs?”

Both Fortiflora and Proviable are formulated for use in both dogs and cats, but how they work can depend on the unique digestive systems of each species. Dogs and cats have some differences in gut flora, so the way these probiotics interact with their digestive systems may vary slightly.

Fortiflora is known for being particularly helpful with cats that suffer from conditions like stress-related diarrhea. Cats tend to be more sensitive to changes in their environment, and this strain of Enterococcus faecium has been shown to help manage acute stress-induced digestive upsets. It’s often favored for short-term relief in cats, especially after vet visits or travel.

Proviable, with its multi-strain formula, offers a more comprehensive solution for both dogs and cats, but it’s particularly beneficial for pets with chronic issues like inflammatory bowel disease (IBD) or recurring digestive sensitivities. Cats, in particular, can benefit from Proviable’s variety of strains if they struggle with more persistent, long-term gut issues. The inclusion of prebiotics also makes it a stronger contender for maintaining ongoing digestive health in cats and dogs alike.

If your pet’s digestive issues are mild and short-lived, Fortiflora could be more appropriate, but for chronic or complex conditions, Proviable may be the better option, especially for long-term management.


Comment 3: “Are there any signs that show Fortiflora or Proviable aren’t working?”

If you’ve started your pet on Fortiflora or Proviable and aren’t seeing the desired results, there are some key signs to watch for. Both probiotics are generally well-tolerated, but it’s important to monitor your pet’s progress closely.

Signs Fortiflora or Proviable may not be working include:

  1. Persistent diarrhea or loose stools:
    If your pet continues to have diarrhea or loose stools after several days of probiotic use, this could be a sign that the product isn’t effective, or there may be an underlying issue that needs further attention. In some cases, you may need a different probiotic strain or even medical treatment.
  2. Increased gas or bloating:
    While it’s common for pets to experience some mild gas when starting a probiotic, excessive bloating or discomfort could indicate that your pet’s gut is struggling to process the formula. This is especially important to monitor with Proviable, as its multi-strain and prebiotic combination can cause temporary gas as the gut flora adjust.
  3. Lack of energy or appetite:
    Probiotics should improve overall gut health, leading to better nutrient absorption and, subsequently, more energy. If your pet’s energy levels remain low or their appetite decreases, it might be a sign that their digestive issues aren’t being resolved. This could indicate that the chosen probiotic isn’t the right fit for your pet’s specific needs.
  4. No noticeable changes after 7-10 days:
    Both probiotics should start to show some positive effects within a week, especially with acute conditions. If you’re not seeing any changes in your pet’s stool consistency, overall demeanor, or gut health after 7-10 days, it might be time to reassess the approach and consult your vet for further guidance.

Comment 4: “What’s the best way to administer these probiotics to a picky eater?”

Administering probiotics to picky pets can be tricky, but there are strategies to make the process smoother:

For Fortiflora, one of the biggest advantages is its flavor. It comes in a powder form that can be sprinkled over your pet’s food, and many pets actually enjoy the taste because it contains animal digest (similar to what’s found in pet food to make it more appealing). If your pet is particularly fussy, you can mix the powder with a small amount of water to form a paste and then coat a favorite treat with it. This can make it more palatable for even the pickiest of eaters.

Proviable offers more flexibility in terms of administration. It comes in both a paste and capsule form. The capsules can be opened and mixed into wet food, or you can wrap them in a small piece of cheese or pill pocket if your pet refuses capsules outright. The paste can be directly administered into the mouth or mixed with a small amount of food. The key with Proviable is its ability to be hidden in food without altering the flavor too much, making it ideal for sensitive eaters.

One more trick: if your pet is particularly suspicious of new additions to their meals, start with a tiny amount of the probiotic and gradually increase the dosage. This can help your pet acclimate to the new taste or texture.


Comment 5: “Can I give Fortiflora or Proviable to my pet every day, even when they’re not sick?”

Yes, daily use of probiotics like Fortiflora or Proviable can be beneficial even when your pet is not showing any symptoms of digestive distress. Probiotics are not just a remedy for diarrhea or upset stomachs; they play a crucial role in maintaining balanced gut flora, which is key to overall health.

In the case of Fortiflora, it is safe for everyday use because it contains a single strain of beneficial bacteria that can help maintain gut stability and prevent digestive upsets from recurring. Pets that are frequently stressed or have sensitive stomachs, such as those traveling often or changing environments, may benefit from this daily addition to their diet. It can act as a preventative measure, helping to regulate digestion and reduce the likelihood of sudden gastrointestinal issues.

Proviable, with its multi-strain formulation and prebiotics, is also suitable for long-term daily use. The diverse strains of bacteria work together to promote a robust immune system and support nutrient absorption, leading to improvements in your pet’s overall health. The inclusion of prebiotics helps nourish the beneficial bacteria in the gut, ensuring they can thrive and provide long-term benefits.

However, while daily administration is generally safe, it’s essential to monitor your pet’s overall health. If your pet shows signs of bloating, gas, or digestive discomfort even after consistent probiotic use, it may indicate that their gut needs a different strain or combination of probiotics, and a discussion with your vet is recommended.

Comment 6: “How long does it take for Fortiflora or Proviable to start showing results?”

The timeframe for when you can expect to see results from Fortiflora or Proviable can vary based on your pet’s condition and individual response to probiotics.

For Fortiflora, because it contains a single strain of Enterococcus faecium, you might begin to see improvements within 24 to 48 hours, especially if your pet is experiencing acute digestive issues like diarrhea or loose stools. This is one of the reasons why Fortiflora is often recommended for short-term, fast relief during times of digestive upset. Its streamlined formula is designed to deliver targeted benefits quickly, addressing immediate symptoms of gut imbalance.

Proviable, on the other hand, might take slightly longer to show visible improvements because it’s designed to rebuild and maintain a healthy gut environment over time. With its multi-strain composition and inclusion of prebiotics, it’s working to repopulate the gut with beneficial bacteria, which is a more gradual process. You may start seeing changes within 3 to 5 days, but for chronic conditions or long-term gut health, the full benefits of Proviable might become more evident after 7 to 10 days of consistent use.

If after 10 days you don’t see any changes, it’s a good idea to consult your veterinarian. There may be an underlying issue that requires a different treatment approach or a more targeted probiotic solution.


Comment 7: “Are there any dietary changes I should make when giving my pet probiotics?”

While giving probiotics like Fortiflora or Proviable can offer great support for your pet’s gut health, adjusting your pet’s diet in conjunction with probiotic use can enhance their effectiveness and further optimize digestion.

If your pet is experiencing digestive issues, switching to a more digestible, low-fat diet can help reduce the strain on their gut. Diets that contain easily digestible proteins (such as chicken or lamb) and limited additives or fillers will make it easier for probiotics to do their job by not overwhelming the digestive system with hard-to-process ingredients.

Additionally, some pets may benefit from a diet with higher fiber content, particularly if they suffer from chronic issues like constipation or loose stools. Fiber helps to regulate digestion, and when paired with probiotics, it can help maintain a healthy balance of gut bacteria. Proviable, with its prebiotic component, already provides some of this benefit, but a fiber-rich diet can work in tandem with probiotics to support more consistent bowel movements.

On the other hand, pets with sensitive stomachs or food allergies may require a more limited-ingredient diet. In this case, introducing probiotics like Fortiflora can help alleviate any lingering digestive discomfort while you identify and eliminate problematic food items.

If your pet’s diet is already balanced and working well, you don’t necessarily need to make drastic changes. However, always ensure your pet is drinking plenty of water, especially when introducing new supplements or dietary changes, to aid in digestion and hydration.


Comment 8: “What should I do if my pet refuses to take the probiotics?”

Some pets can be a bit stubborn when it comes to taking supplements, but there are several creative strategies you can try to make the process easier.

For Fortiflora, which comes in a powder form, it’s designed to be easy to administer by simply sprinkling it on your pet’s food. If your pet is turning up their nose at their meal after you’ve added the probiotic, consider mixing it with a small amount of wet food or a treat they can’t resist. You can also dissolve the powder in a small amount of water and offer it on a spoon or syringe, which can sometimes be more palatable for pets sensitive to changes in texture or flavor.

Proviable offers more options, as it comes in both capsule and paste forms. For pets who resist capsules, you can open the capsule and sprinkle the contents over their food, much like Fortiflora, or use a pill pocket to disguise it. The paste form of Proviable can be administered directly into your pet’s mouth or mixed into a favorite soft food. Many pets are more receptive to paste forms of supplements because the texture is easier to tolerate than powders or capsules.

If you’re still struggling, one tip is to introduce the probiotic slowly. Start by mixing a small amount into your pet’s meal and gradually increase the dose over several days. This helps them get used to the new taste or smell without overwhelming them. Consistency and patience are key, and finding the right method may take a little trial and error.

  1. My 10-year-old mixed breed pup has had digestive issues for several years. mostly diarrhea sometimes bloody. In the past, I’ve given him a proviable forte kit, capsules, and paste. He recently had an episode of diarrhea. I wanted to purchase the proviable forte kit but found it is only available through the vet. I’m wondering what the difference is between the proviable forte kit and the plain proviable kit available from the pet store. Since this has been a chronic problem and I know how to treat it, I’d like to avoid an unnecessary vet visit which in itself is stressful. Can you tell me what the difference is between the 2 products.

    1. Since your 10-year-old mixed breed has been battling chronic diarrhea—sometimes even bloody—it’s awesome that you’re on top of finding solutions that work for him. You’ve used the Proviable Forte Kit before, and now you’re eyeing options to manage this latest flare-up without the hassle of a vet trip. I totally get wanting to skip the stress of an appointment, especially when you’ve got a handle on what helps. So, let’s break down the differences between these two products in a way that’s clear, detailed, and gives you the confidence to choose what’s best for your furry friend.

      The Proviable Forte Kit is like the deluxe edition of digestive support, designed with a bit more oomph for dogs (and cats) facing intestinal imbalances. It’s a two-part system: you get a tube of KP paste and a set of sprinkle capsules. The paste is a short-term helper, packed with kaolin and pectin—natural ingredients that coat the gut and firm up loose stools fast, usually within 48-72 hours. Think of it as a quick fix to stop the runny mess while the capsules get to work. Those capsules? They’re loaded with 10 billion CFUs (colony-forming units) of seven beneficial bacterial strains per dose, plus two prebiotics to feed those good bugs and help them settle in your pup’s gut. This combo is meant to tackle bigger disruptions—like after antibiotics, stress, or chronic issues—and it’s exclusive to vets because of its potency and the need for proper guidance on use.

      On the flip side, the plain Proviable Kit—sometimes labeled just as “Proviable” or “Proviable-DC Kit”—is the more basic version you can snag at pet stores or online without a vet’s nod. It also comes with a KP paste and capsules, but here’s the kicker: the capsules only deliver 5 billion CFUs per dose with the same seven bacterial strains and prebiotics. It’s still a solid choice for rebalancing the gut, especially for milder upsets like a dietary slip-up or temporary stress, but it’s got half the probiotic punch of the Forte version. The paste works the same way—kaolin and pectin to firm things up—but the overall kit is gentler, making it more accessible for everyday pet parents who don’t need the heavy-duty stuff.

      Now, why does this matter for your pup? With his history of chronic diarrhea, sometimes bloody, the Forte Kit’s higher probiotic count might be why it’s worked well for him before—it’s got more firepower to restore order in a gut that’s been off-kilter for years. Bloody stools can hint at inflammation or irritation, and while both kits can help, the Forte’s extra bacteria could offer a stronger boost to calm things down long-term. The plain kit isn’t weak by any means, but it’s more of a maintenance or light-recovery tool, not the big gun for stubborn, recurring issues.

      Here’s a little side note: the Forte Kit’s vet-only status isn’t just about control—it’s because vets want to ensure it’s used right, especially since the paste shouldn’t be overdone (it can cause constipation if used too long), and the higher CFU count might not suit every dog, like those with super-sensitive systems. But since you’ve used it successfully before, you’ve got a good sense of how your pup responds.

      So, could the plain Proviable Kit work for this episode? Possibly! If the diarrhea isn’t as severe this time—no blood, less frequency—it might hold the fort until things settle. But if it’s a full-on repeat of past flare-ups, the Forte’s extra strength could be the smarter play. You know your pup best, and avoiding the vet stress is a big plus. Just keep an eye on him—if the plain kit doesn’t firm things up in a couple days or if blood shows up, that’s your cue to rethink the plan.

      Probiotic Power 10 billion CFUs per capsule 5 billion CFUs per capsule

      For your situation, the Forte Kit’s edge lies in its beefier probiotic dose, which could be key for a chronic case like your pup’s. The plain kit’s still a contender, though—easier to grab and less intense if you’re testing the waters. Either way, you’re a rockstar for staying proactive about his health! Keep watching how he does, and you’ll nail the right move for this round.
