CARNIVORE BIOTICS
Carnivore Gut Health Probiotic - 3-Pack (90-Day Supply)
A 90-day microbiome rebuild for carnivore and keto. The most-asked question among meat-based eaters, how long does it take to heal your gut on the carnivore diet, has a consistent answer: most people see initial improvements in the first few weeks, but full microbiome adaptation takes closer to three months. This three-bottle bundle is built for the people committed to the full rebuild, not just the transition. Each delayed-release capsule delivers 30 billion CFU across three bile-tolerant strains formulated for a high-fat, low-fiber gut. LR08 L. reuteri produces bile salt hydrolase to support fat digestion and the absorption of fat-soluble vitamins (A, D, E, K). LRa05 L. rhamnosus supports intestinal barrier integrity and metabolic adaptation during ketosis. LG08 L. gasseri supports visceral fat management and healthy body composition. Save 15% versus single bottles. Zero fillers, sugars, or starches. NPN-licensed by Health Canada (NPN 80145666) and manufactured in an FDA-registered, GMP-certified facility.

90-Day Protocol
The 90-Day Microbiome Rebuild Timeline
The most-asked question among carnivore and keto eaters, how long does it take to heal your gut on a meat-based diet, has a consistent answer: most people see initial improvements in the first few weeks, but full microbiome adaptation takes closer to three months. The 3-Pack is built for the full rebuild, not just the transition. Here's what happens at each stage, and how Carnivore Gut Health Probiotic supports each phase.
Weeks 1–2: The Bile Bottleneck
Your fat intake has jumped sharply, and your gallbladder hasn't scaled bile production to match. This is when carnivore diet diarrhea, urgency after fatty meals, and the digestive symptoms commonly called carnivore flu are most likely to appear. LR08 L. reuteri produces bile salt hydrolase, which supports more efficient bile recycling and fat emulsification while your own bile capacity expands.
Weeks 3–6: The Microbiome Turnover
Fiber-fermenting bacteria are fading because there's no fiber to feed them, and bile-tolerant, protein-fermenting bacteria are establishing in their place. Bloating typically resolves, bowel patterns shift toward less frequent but firmer movements, and energy starts stabilizing between meals. LRa05 L. rhamnosus supports intestinal barrier integrity during this turnover, important because the gut wall is most vulnerable during microbiome change.
Weeks 7–10: Fat Adaptation
By the second month, your mitochondria are running on fat efficiently and your bile capacity has scaled up to match your intake. Most users report that digestion has stopped being something they think about, it's just working. This is also when the gut-brain axis effects (mental clarity, more stable mood, deeper sleep) typically become noticeable. The probiotic continues to reinforce barrier function and support the now-stable ecosystem.
Weeks 11–13: Full Rebuild
By the third month, the microbiome remodeling is durable. The bile-tolerant strains that established in weeks 3–6 are colonized, the gut wall has recovered from the dietary turnover, and fat digestion is operating at a higher baseline than it was at week one. LG08 L. gasseri's contribution to metabolic balance and body composition is most observable in this window, after the foundational digestive work is done.
What Comes After 90 Days
A full 90-day rebuild gives most users a microbiome that's adapted to a meat-based diet rather than just tolerating one. Many continue the probiotic long-term as maintenance; the supporting effects on bile recycling and barrier integrity remain relevant as long as you're eating high-fat. For the deeper science behind the rebuild, see our guide on how to rebuild your gut microbiome on a meat-based diet. Take each capsule with your highest-fat meal of the day.
Apex Advantage · Level II
WHAT CARNIVORE GUT HEALTH UNLOCKS
Beyond the baseline. Precision optimization for the modern predator.
Lion's Focus
Supports the gut-brain connection to promote mental clarity. By helping to stabilize neural pathways, CARNIVORE BIOTICS assists in reducing mental fatigue and supports sustained, high-level concentration.
Immune Support
Contributes to a resilient internal defense by helping to diversify the gut bacteria that support the immune system. This helps maintain natural barriers and aids daily recovery.
Digestive Strength
Helps the body more effectively utilize nutrients from your diet. By priming the gut environment, CARNIVORE BIOTICS supports the absorption of essential vitamins and fats for improved efficiency.
Energy Engine
Supports healthy mitochondrial function and metabolic flexibility. CARNIVORE BIOTICS helps the body more efficiently process fat for steady, all-day energy without the common, mid-afternoon energy crash.
Sleep & Recovery
Promotes a healthy balance of the hormones responsible for rest and stress. By helping to calm the nervous system, it contributes to a more restful, restorative sleep.
Skin & Vitality
Supports the gut-skin axis to promote healthy-looking skin from the inside out. It helps manage internal balance, leading to better structural integrity and a more vibrant appearance.

DELAYED-RELEASE TECHNOLOGY
Our capsule is engineered with an acid-resistant coating that only dissolves at the alkaline pH of the small intestine.
Ingestion
Capsule enters stomach intact, no premature breakdown.
Acid Bypass
Resistant coating shields bacteria from pH 1.5–3.0 stomach acid.
Targeted Release
Dissolves at pH 6.0+ in the small intestine for maximum colonization.
THE STRAIN PROFILES
Every strain was chosen for a specific role in the carnivore microbiome.
L. reuteri
Bile Support & Lipid Metabolism
- Aids fat digestion by producing bile salt hydrolase, which supports the breakdown of complex fats.
- Assists in easing the transition to high-fat diets, helping to minimize temporary digestive upset.
- Promotes the efficient absorption of fat-soluble vitamins (A, D, E, and K).
- Demonstrates high resilience, contributing to its ability to survive harsh gastric environments.
L. rhamnosus
Barrier Integrity & Metabolic Adaptation
- Supports 'tight junction' integrity, helping to maintain a strong and healthy intestinal barrier.
- Contributes to a smoother metabolic shift, assisting the body in maintaining ketone levels during adaptation.
- Helps manage markers of systemic inflammation by supporting gut-wall defenses.
- Aids in natural immune system modulation and response.
L. gasseri
Metabolic Balance & Composition
- Associated with the management of visceral fat and supporting healthy body composition goals.
- Helps maintain healthy uric acid levels, providing essential support for those on red-meat-heavy diets.
- Contributes to a healthy metabolic rate and overall energy balance.
- Assists in long-term weight management efforts when paired with proper nutrition.
Pro Tip
Take Carnivore Biotics CB-30B-CFU with a high-fat meal. The bile produced during fat digestion activates L. reuteri's bile salt hydrolase, making fat emulsification more effective and maximizes strain synergy.
