- Enhance rest
- Help in Sleep Quality

5-Hydroxytrytophan (HTP) enhanced the activity of serotonin, a
hormone produced by the brain that is involved in mood, sleep,
and appetite. Low levels of serotonin are associated with
disturbed rest.

Usage: Take 1 capsule per day on an empty stomach, or as
directed by your qualified health consultant. Do not exceed
recommended amount. NOTE: Do not take if pregnant, lactating,
trying to conceive, under age 18, or have a medical condition. If
taking perscribed medication(s), e.g. antidepressant SSRIs, MAO
inhibitors or sedatives, consult health professional before taking
5-HTP.

Jarrow formulas® 5-HTP (5-Hydroxytryptophan) is an extract of
Griffonia simplicifolia seeds from coastal West Africa and is
verified to be free of “peak X” contaminant. Purity is assured by
HPLC. 5-HTP is the direct metabolic precursor of serotonin and
is important for the production of melatonin.
