As probiotics continue to gain their deserved recognition in helping to alleviate and mitigate various issues originating in the GI tract, they are now also being considered for therapeutic use for a range of other conditions. It appears that this enteric system with a "brain" of its own has more influence over brain processes – which include thinking – than previously believed. For instance much of our neurotransmitters are manufactured in the GI tract. This fact alone means your GI health is linked to the health of your brain and nervous system.
With this knowledge in mind, a team of researchers in Spain hypothesized that fibromyalgia (FM) may benefit from probiotics, stating their use "might be a new treatment that could improve the physical, psychological and cognitive state in FM."
