Is anyone aware of a supplement that is shown to reduce serotonin levels in the brain?
Low serotonin is thought to cause pathological mental conditions such as depression. However, there is some evidence that higher levels of serotonin may be implicated in some forms of anxiety. Which makes some sense, in spite of the fact that SSRIs and SNRIs are frequently prescribed for anxiety and sometimes work. These drugs have other effects aside from preventing serotonin reuptake, notably increasing BDNF leading to increases in brain volume and dendritic connections.
I'm wondering if anyone knows of a supplement that either decreases serotonin synthesis or acts as a receptor antagonist?
