Nitrolithic Labs | Gutriva20 Probiotic | 20 Billion CFU | 30 Caps | Digestive & Immune Support

The gut microbiome does considerably more than digest food. It produces neurotransmitters, regulates immune function, synthesizes certain vitamins, and communicates with the brain via the vagus nerve. Gutriva20 delivers 20 billion CFU per serving across 13 probiotic species to support microbial diversity and gut function.

What's inside and why it matters:

1. 20 billion CFU per serving (at manufacture): A meaningful dose for daily maintenance. Adequate for most adults eating a varied diet who want consistent gut support.
2. Multiple Lactobacillus and Bifidobacterium strains: Different strains colonize different parts of the gut and perform different functions. Strain diversity matters more than CFU count alone.
3. Supports digestion and immunity: 70-80% of the body's immune tissue lines the gut wall. Microbial health directly influences immune function.

Here's the Science

A 2019 review in Cell found that gut microbiome composition influences metabolic health, immune regulation, neurological function, and mood — through direct production of neurotransmitters like serotonin (approximately 90% of which is produced in the gut) and through signaling pathways connecting the gut to the brain.

Lactobacillus acidophilus colonizes the small intestine, produces lactic acid that inhibits harmful bacteria, and supports lactose digestion. Bifidobacterium strains are the primary colonizers of the large intestine and are most associated with healthy immune regulation.

Helps replenish and maintain a healthy balance of gut bacteria, especially when your routine gets thrown off.

Suggested use: One capsule daily with or without food. Refrigerate after opening to extend shelf life.
