Did you know that your "gut feeling" actually does come from your gut? Bacteria in your gut can influence how you feel.
Serotonin: A Natural Hormone Controls Mood
95% of serotonin in your body is created and located in your gut (1). Serotonin is a chemical that is responsible for balancing our mood and is sometimes called a “happy hormone”. A deficit of serotonin leads to depression. Drugs for treating anxiety and depression, like Prozac, Zoloft, and Paxil, work by modulating levels of serotonin.
Bacteria Signal Your Gut to Produce Serotonin.
A recent study showed that certain bacteria in the gut regulate the production of serotonin in colon cells (2). It is reported that probiotics could up-regulate the serotonin transporter protein (3).
Multispecies probiotics studies showed that probiotics could be used as a potential preventive strategy for depression and obsessive–compulsive-like behaviors (4, 5).
