-HTP is a naturally-occurring amino acid and the precursor to serotonin, the neurotransmitter often touted for its role as a “happiness hormone”. Taking 5-HTP is a simple way to increase brain serotonin levels.
5-HTP affects the brain and the central nervous system by increasing the production of serotonin. Low levels of serotonin can affect sleep, appetite, sexual behavior. 5-HTP has been proven to reduce symptoms of low-mood, improve sleep and sometimes aid within a weight loss regimen.
