13 Week Kit — Bravo Probiotic Yogurt — 300 Probiotic Strains
Microbiome Restoring Probiotic System
Our most comprehensive kit for a full 13-week probiotic protocol. Contains everything needed to make Bravo Probiotic Yogurt at home.
Key Features
The 13-Week Bravo Probiotic Yogurt Kit is our flagship product — a complete, all-inclusive system for producing the world's most probiotic-rich yogurt in your own home. This kit provides a full 13-week supply of the Swiss-formulated Bravo culture, containing over 300 distinct probiotic strains.
Bravo Probiotic Yogurt is not an ordinary yogurt. It is a scientifically engineered fermented food that replicates the complex microbial ecosystem of the human gut. Unlike commercial yogurts that contain 2–5 strains, Bravo contains the full spectrum of bacteria, yeasts, and other microorganisms found in a healthy human microbiome.
What Makes Bravo Unique
The Bravo formula was developed by Dr. Marco Ruggiero, a molecular biologist and former professor at the University of Florence. The culture is based on colostrum and whey proteins, which serve as the ideal substrate for the complex microbial community. During fermentation, the culture produces:
- GcMAF — the macrophage-activating factor that supports immune function
- Short-chain fatty acids — including butyrate, propionate, and acetate for gut lining integrity
- Bacteriocins — natural antimicrobial peptides that suppress pathogenic bacteria
- Vitamins B12, K2, and folate — synthesized during fermentation
- Bioactive peptides — derived from the colostrum and whey substrate
The 13-Week Protocol
The 13-week protocol is designed to achieve a comprehensive restoration of the gut microbiome. Research suggests that meaningful, lasting changes to the microbiome require consistent probiotic exposure over an extended period. The 13-week kit provides the optimal duration for this process.
Each kit contains 13 individually packaged culture sachets, one per week, along with detailed preparation instructions, a thermometer, and a preparation guide booklet.

Published by Bravo's formulator Dr. Marco Ruggiero, this study demonstrates that GcMAF — produced naturally during Bravo's fermentation — stimulates macrophages to attack and destroy cancer cells. It provides direct mechanistic evidence for GcMAF's role in immune activation.
