L. Bulgaricus
Brand: Custom Probiotics
Dr. Feb's Analysis
Scientific Mechanism
The primary active ingredient, L. bulgaricus, is a transient lactic acid bacterium. At the cellular level, it ferments lactose to produce lactic acid, lowering gut pH. This acidic environment inhibits pathogenic bacteria growth. L. bulgaricus also produces bacteriocins—natural antimicrobial peptides—that disrupt harmful bacterial cell walls. Unlike adherent strains, it passes through the digestive tract, aiding digestion and modulating the immune response via interaction with gut-associated lymphoid tissue (GALT) before excretion.
Key Benefits
Key benefits include:
- Supports transient gut microbiome balance
- Aids in lactose digestion and reduction of bloating
- Produces lactic acid to maintain healthy pH levels
- Supports immune system function via GALT interaction
Usage & Safety
Best practices: Take 0.1 gram (100mg) daily. Mix powder with water or a cool beverage; do not use hot liquids as heat kills bacteria. For best results, consume on an empty stomach, preferably 30 minutes before a meal or 2 hours after. Store in a cool, dry place or refrigerator to maintain potency. Consult a healthcare provider if you are immunocompromised or taking antibiotics.
