Introduction
Just a couple of days ago, scientists from FOODBIOMES, in collaboration with our team at QLC, published a study in Medicina showing that there are alternative ways to enjoy the benefits of probiotic foods beyond dairy and other fermented products. Instead, we leveraged everyday oat flakes as a delivery vehicle for Lactococcus cremoris—friendly microbes that can help maintain a balanced gut ecosystem.
What we did
Fifty-four healthy adults joined a twelve-week study. Half of them ate just five grams of plain oat flakes each day, while the other half ate five grams of oat flakes coated with Lactococcus cremoris. Nobody knew which version they had until the end. At the start, the halfway point (six weeks), and the finish (twelve weeks), the researchers took simple blood and urine tests to check things like inflammation, blood-sugar control, vitamin levels, and stress hormones.
What we found
By the end of the trial, people eating the probiotic oats showed a clear drop in their C-reactive protein, a key sign of inflammation in the body. They also tended to have lower levels of another inflammation signal, IL-6. Around six weeks in, their insulin measurements suggested their bodies were handling sugar more smoothly, though that difference wasn’t as strong at twelve weeks. On top of that, the probiotic group saw a boost in vitamin B₁₂ and healthier patterns in their stress hormone (cortisol), hinting at both better nutrient absorption and lower stress.
Why it matters
These findings show that a small daily serving of oats carrying beneficial bacteria can help reduce inflammation, support balanced glucose metabolism, and enhance micronutrient status—all without any dairy or fermented product. This exciting result paves the way for innovative, plant-based-, non-fermented-probiotic foods. Stay tuned on the QLC website for upcoming studies as we expand our research, refine optimal dosing, and continue our mission to develop accessible, science-backed health solutions.
