I've noticed that my 'first' brain acts faster and better if my 'second' brain is feeling good. Probiotic foods, plenty of water and movement have been key factors there.
what kind of probiotic foods have you successfully included in your daily life?
I am in no way an expert and only have experiments on myself to go off, but I've been experimenting on this particular question for a decade or so my anecdata might be thicker than average.
Probiotics to recover from antibiotics, prebiotics to maintain.
