THE LIVER, THE GUT AND A MILK BACTERIUM: what a new study teaches us and why it pertains to the Bravo approach
A study published in September 2026 by a team at Emory University (Atlanta) investigated a lactic acid bacterium very common in fermented products, Lactococcus lactis subsp. cremoris, abbreviated as LLC.
It is not an exotic bacterium: it is the same type of microorganism used for centuries to make cheese and yogurt. The authors wanted to understand how this single strain influences the gut-liver axis, that is, the constant dialogue between what lives in the intestine and the liver, which receives from the portal blood metabolites, bile acids, and substances originating from digestion.
What they found, in simple terms: In mice fed a Western-style diet (rich in fats and sugars), LLC noticeably altered metabolites in the blood and liver. In particular, pathways related to the following improved:
lipid metabolism�transformation of foreign substances (xenobiotics, meaning drugs, toxins, dietary compounds)�redox balance (the ability of cells to manage oxidative stress)��LLC also reduced two different types of experimental liver damage: the accumulation of fat in the liver following an acute alcohol load and liver cell death following an overdose of paracetamol (acetaminophen).
A particularly clear result: LLC, even on its own, was sufficient to reorganize liver metabolism.
How this study connects to Bravo
In 2025 René Badolato and Marco Ruggiero described in the International Journal of Radiology & Radiation Therapy the case of an 83-year-old man with already documented hepatic fibrosis. Liver stiffness measured by FibroScan was 7.6 kPa, an index of moderate fibrosis, stage F2. After about six months of daily intake of Bravo (Freeze Dried Bravo) the value had dropped to 3.6 kPa, compatible with the absence of fibrosis (F0).
During the same period other parameters also improved: blood glucose, creatinine, BUN, red blood cell indices (MCH and MCHC), and a reduction in white blood cells, interpreted as a decrease in a low-grade chronic inflammatory state.
Why the study on LLC helps interpret the results observed with Bravo
The Emory study uses a single strain. Bravo, on the other hand, is not a single strain; it is complete microbiome restoration system with a far higher biodiversity: hundreds of strains, phages, plasmids, in addition to prebiotics and postbiotics produced during fermentation, including naturally derived GcMAF.
The list of microorganisms associated with Bravo includes numerous strains of Lactococcus lactis subsp. cremoris (in addition to L. lactis subsp. lactis), along with many species of Lactobacillus, Bifidobacterium, Leuconostoc, and others. Therefore, the bacterium studied at Emory is present within the Bravo ecosystem, but it is not the sole actor.
If a single LLC is already capable of:
remodeling serum and hepatic metabolites��reducing intestinal bile acid conjugation��attenuating damage from alcohol and paracetamol��then a product containing that strain plus dozens of other lactobacilli and bifidobacteria, plus fermentation metabolites, plus colostrum components, can be understood as an amplification of the same principle: acting on the gut-liver axis on multiple levels simultaneously (intestinal barrier, bile acids, oxidative stress, systemic inflammation, detoxification).
The message for those who follow Bravo research is clear. We are talking about a bacterium already contained in the product, studied with advanced tools, whose effects point in the same direction as the clinical observations on Bravo, a much richer product.
