Are there any supplements that can help boost serotonin levels?

5-HTP (natural Amino Acid 5-hydroxytryptophan) may help to promote the brain chemical Serotonin. 5HTP is a naturally occurring amino acid from which the neurotransmitter serotonin is made. Serotonin appears to play significant roles in sleep, emotional moods, pain control, inflammation, intestinal peristalsis, and other body functions.

5-htp and St. Johns wort may boost serotonin levels. There has not been a huge amount of research into this and although they are classified as supplements by law there are not any general chemical distinctions between supplements and drugs.

Also tryptophan is available, which is the pre-cursor to 5-htp. Magnesium and vitamin B6 aid in the conversion to serotonin.
