Probiotics: Brain - Gut Axis and Better Mood, Better Memory

I just received an email from Harvard Medical School with their publication on probiotics elevating mood. 

In fact, the research they cited was not just about elevating mood, calming the mind and heart, but the significant positive effect of probiotics on the cognition of Alzheimer's patients (Akbari et al., 2016), and the ability to withstand stress (Guiao et al., 2021). 

We have discussed brain - gut axis for many years, one of Seann's favorite topics! The gut is called a 'second brain' since it produces many of the neurotransmitters as the brain does (e.g., serotonin, dopamine) and hence plays an important role in regulating our mood. 

I have also written on 'psychobiotics' - probiotics used for depression and enhancing our mood. Recent research literature from the last year or so show hundreds of articles on probiotic intervention studies for cognition, mood, better mood, and neurological conditions such as Alzheimer's and Parkinson's. 

Take a look at the references below for some encouraging research articles.
