There is far more serotonin within our digestive system than is located within our brain. Serotonin seems to be related to our moods and lower amounts seem to cause mental problems. But we don't have enough knowledge to understand how this works. I suspect that learning how serotonin works within the digestive system as well as the brain would be more helpful to us understanding more about this.
A natural source that creates serotonin is salt. There are scientists that argue we have reduced too much salt within our diets. They say that our salt requirements are now almost 50% lower than it should be.
