I don't know the exact percentages, but I know that most of it is in other organs such as the digestive tract. There are also different types of serotonin.
Current thinking among mainstream docs is that although some antidepressants increase serotonin,
that's probably not how they relieve anxiety and depression.According to a recent Newsweek, they think that they work by some other currently unknown mechanism which increases the size of a certain part of the brain called the hippocampus. Imaging shows that depressed people tend to have a smaller than normal size hippocampus. With AD treatment, it increases to a more normal size. But the docs now think that increased serotonin is a by-product rather than a reason for the antidepressant effect.
