Can probiotics help prevent Alzheimer's Disease
We wanted to share a new 2025 study that shows how improving your gut health
might help protect your brain from Alzheimer's disease.
What the study found:
Researchers gave a special mix of probiotics (10 different strains)
to mice that were genetically programmed to develop Alzheimer's disease.
After 16 weeks, these were the results:
Better memory and learning ability.
Less brain inflammation.
Reduced toxic protein buildup (the hallmark of Alzheimer's).
And a stronger protective barrier around the brain.
The study shows that an unhealthy gut allows harmful substances
to leak into your bloodstream, causing inflammation throughout your body.
This inflammation eventually reaches your brain
and contributes to Alzheimer's disease.
The probiotics helped combat this by strengthening the gut barrier to prevent a leaky gut.
They also reduced the amount of inflammation in the gut,
which led directly to less inflammation in the brain.
What this means for you:
While this study was done in mice, it's the first to show that probiotics can actually
prevent Alzheimer's-like brain damage through the gut-brain pathway.
This gives us a potential new tool that might help
protect against cognitive decline as we age.
We will keep you updated as new studies around this emerge.
P.S. We released a new ingredient called Probiotic last year,
which is a combination of 10 different probiotic strains that strengthen your gut microbiome.
