A study published in Nutritional Neuroscience in January 2026 is adding fresh scientific weight to something many Bravo users already feel: what happens in the gut doesn't stay in the gut.
Researchers looked at how milk kefir affects both gut and brain health, and found measurable improvements across several markers, from gut tissue repair to blood-brain barrier strength. It's a striking illustration of what's known as the "psychobiotic effect," where the health of the gut microbiome directly influences brain function.
In his latest video, Dr. Marco Ruggiero walks through the study's findings and explains what they mean for Bravo, which shares the same living microbial spectrum found in traditional kefir, along with fermented colostrum and GcMAF activity.
