The Carnivore Diet: A "Gut Reset" in Itself
Many advocates of the carnivore diet argue that its very nature makes external probiotic supplementation unnecessary, and potentially counterproductive. By eliminating all plant-based fibers, carbohydrates, and plant toxins, the diet removes the fermentable materials that feed many types of gut bacteria.
The Argument Against Probiotic Supplements
Proponents of this view suggest that the carnivore diet inherently promotes a healthy, balanced gut microbiome without outside intervention. Their reasoning includes:
- Removal of Stressors: Plant-based foods contain anti-nutrients and toxins like lectins, which can contribute to gut inflammation and permeability. Eliminating these substances allows the gut lining to heal.
- Natural Selection: Without plant-based carbohydrates, the gut microbiome adapts to a different food source. The bacteria that thrive on fiber and starch die off, while those that can digest protein and fat flourish. Introducing external bacteria via supplements might disrupt this natural selection process.
- Lack of Evidence: Some clinical reviews suggest there is little to no evidence that probiotic supplements benefit the microbiota of healthy individuals. For those who follow the diet for autoimmune issues, probiotics may even be contraindicated.
- Potential Risks: The use of probiotics is not without risks, particularly for those with compromised immune systems. Concerns include infections from the microorganisms, transfer of antibiotic resistance genes, or contamination in unregulated supplements.
Arguments for Probiotic Use on Carnivore
Conversely, some individuals and practitioners believe that supplementing with probiotics can be beneficial, especially when starting the diet or dealing with specific digestive issues. This viewpoint acknowledges that the abrupt dietary change can be a shock to the system, and probiotics may ease the transition.
Reasons to Consider Probiotics
- Easing Transition: During the initial phase, digestive upset such as bloating, constipation, or diarrhea is common. Introducing beneficial bacteria can help restore balance and reduce these temporary issues.
- Replenishing Bacteria: The lack of fiber on a carnivore diet means the old gut bacteria are starved. A probiotic supplement can help introduce beneficial bacteria to repopulate the gut and aid in the digestion of meat and fat.
- Immune Support: Probiotics are known to support immune function, which can be a concern for some on highly restrictive diets.
- Targeted Support: Certain strains of probiotics, like Lactobacillus casei and Bifidobacterium lactis, are specifically known to assist with digestion and may be helpful for those who still experience discomfort.
Carnivore-Friendly Probiotic Sources
For those who wish to incorporate probiotics, relying on fermented foods or carefully selected supplements is key. Plant-based fermented foods like sauerkraut or kombucha are not carnivore-friendly due to their carbohydrate and plant content. Instead, consider animal-based or carefully chosen options:
- Fermented Dairy: Traditional buttermilk and aged cheeses (like gouda, cheddar, and mozzarella) contain live cultures. For those who tolerate dairy, these can be a viable option.
- High-Quality Supplements: Seek out reputable probiotic supplements containing multiple bacterial strains and a high CFU count. Ensure the product is shelf-stable or properly refrigerated to maintain potency.
- Bone Broth: While not a probiotic in itself, homemade bone broth provides gelatin, which can support gut lining health.
Comparison of Carnivore Diet and Probiotic Benefits
| Feature | Carnivore Diet Effect | Probiotic Effect (Advocated) |
|---|---|---|
| Mechanism | Removes plant-based fermentable fibers and toxins, naturally resetting gut flora. | Introduces beneficial bacteria to colonize the gut and rebalance the microbiome. |
| Application | Long-term strategy for gut health improvement, especially for those with autoimmune or inflammatory issues. | Short-term aid to manage digestive symptoms during the transition phase of the diet. |
| Microbiome Diversity | Selectively eliminates bacteria that thrive on carbs, leading to a narrower but potentially more stable meat-adapted microbiome. | Aims to increase diversity by introducing new strains, which some argue can promote a healthier gut. |
| Primary Goal | Heals the gut lining by removing irritating plant compounds. | Supports digestion and nutrient absorption, and boosts immune function. |
| Potential Risks | May lead to an unbalanced microbiome initially, causing temporary digestive issues. | Infections, transfer of resistance genes, and d-lactic acidosis in susceptible individuals. |
| Sourcing | Inherent to the diet itself (meat and fat). | Derived from specific fermented animal foods or high-quality supplements. |
Conclusion: Making an Informed Decision
Ultimately, the decision to take probiotics on a carnivore diet is personal and depends on individual health goals and body response. Many thrive without them, finding that removing inflammatory plant foods is all that's needed to restore gut health. For these individuals, supplements could be an unnecessary and potentially risky expense. However, for those struggling with digestive discomfort during the initial adaptation phase, a high-quality, carnivore-friendly probiotic supplement or food source may provide welcome support. A sensible approach is to first try the diet without supplements, and only consider probiotics if persistent issues arise. Consulting a healthcare professional is always recommended before making significant changes to your dietary or supplement regimen.

Additional Considerations for Gut Health on Carnivore
Beyond the probiotic question, other factors can influence gut health on a carnivore diet. These include stress management, getting adequate sleep, and proper hydration. Consuming bone broth can also be a beneficial practice, as it provides nutrients that support gut lining integrity. These foundational lifestyle factors are crucial for overall digestive wellness, regardless of whether you choose to add a probiotic to your regimen.
Making Your Choice
Your body's response to the carnivore diet is the best indicator of whether probiotic supplementation is necessary. If you feel great, have regular digestion, and experience symptom relief, adding a supplement might not be needed. If you face persistent issues like bloating or constipation, a short course of a high-quality probiotic could be helpful during the transition. Listening to your body and making slow, intentional changes is the most effective strategy for optimizing gut health on this dietary approach.
