Better digestion starts with a balanced microbiome.
Your gut is home to trillions of microbes but only a few have the power to truly transform your health.
When it comes to gut health, the details matter. The right probiotic strains can restore microbial balance, strengthen the intestinal barrier, and regulate immune function.
VitaminLab’s Advanced Probiotic Support Formula provides a blend of spore-forming bacteria, beneficial microbes, and yeast-based probiotics. Practitioners have exclusive access to this protocol in our portal. Consumers looking for probiotic options can include these when creating their custom VitaminLab formula.
Why Gut Health Matters
Your gut microbiome isn’t just about digestion. It’s a living ecosystem that influences inflammation, nutrient absorption, mood, and even immunity.
Stress, antibiotics, travel, and dietary choices can disrupt this balance, leading to bloating, irregularity, or fatigue.
Clinically supported probiotics help restore equilibrium, supporting both short-term relief and long-term microbiome resilience.
The VitaminLab Difference
VitaminLab’s Advanced Probiotic Support Formula isn’t one-size-fits-all (find out why True Personalization is better than Pill Packs here).
The formulation offers a clinically validated foundation for addressing digestive dysfunction, inflammation, or immune imbalance with the flexibility to pair it with complementary products like VitaminLab GI Repair for comprehensive GI recovery.

What’s Inside: Key Protocol Ingredients
Bacillus clausii – 2 Billion CFU
A resilient spore-forming probiotic shown to withstand gastric acid and colonize the intestine. B. clausii is known for its immunomodulatory properties, supporting both innate and adaptive immunity. Clinical studies show benefits in restoring gut microbiota homeostasis (1, 2).
Bacillus coagulans – 3 Billion CFU
Known for its ability to survive stomach acid and help regulate gut flora. Research shows this strain improves bloating, abdominal pain, and stool regularity in individuals with IBS and dysbiosis. It also supports immune function and anti-inflammatory balance (3).
Bacillus mesentericus – 2 Billion CFU
Traditionally used in Japanese gut formulations, this strain supports digestive enzyme production and encourages the growth of other beneficial microbes. It’s often used in synbiotic blends to amplify probiotic colonization and support nutrient absorption in elderly populations (4).
Bacillus subtilis – 2 Billion CFU
A well-researched soil-based probiotic known for promoting intestinal barrier integrity, reducing inflammatory markers, and resisting pathogenic bacterial overgrowth. It plays a key role in detoxifying the gut, supporting SCFA production, and modulating immune pathways (5).
Bifidobacterium bifidum – 1 Billion CFU
A core member of the gut microbiota, B. bifidum supports the breakdown of complex carbohydrates and maintains intestinal barrier function. It also helps crowd out harmful bacteria and has been linked to improvements in IBS symptoms and immune response (6).
Lactobacillus acidophilus – 2 Billion CFU
One of the most studied probiotic strains, L. acidophilus supports gut HP balance and may prevent pathogen colonization. It’s beneficial in reducing diarrhea, gas, and bloating, particularly after antibiotics or during travel (7).
Lactobacillus rhamnosus – 5 Billion CFU
Clinically shown to improve diarrhea outcomes, vaginal microbiome balance in women, and eczema symptoms in children, L. rhamnosus is one of the most effective and researched probiotics available. It enhances gut-immune communication and reduces intestinal inflammation (8).
Saccharomyces boulardii – 5 Billion CFU
A probiotic yeast with strong evidence in managing antibiotic-associated diarrhea, Clostridioides difficile infections, and traveler’s diarrhea. It helps restore intestinal homeostasis, prevents pathogen binding, and supports gut lining repair. Unlike bacterial probiotics, it is not killed by antibiotics (9).
