5-HTP Plus
capsules (60ct)
$36.80
5-HTP Plus Formula capsules, provided by
Douglas Laboratories, contain 75 mg of natural
L-5-hydroxytryptophan (5-HTP) extracted from seeds of
the Griffonia plant, together with 7.5 mg of
pyridoxal-5-phosphate and 50 mg of a proprietary
blend of the neurotransmitters L-tyrosine and L-glutamine. This product has been certified to be free of a
contaminant, peak "x", implicated in a past incidence of
dietary tryptophan-associated eosinophilia myalgia
syndrome (EMS).
FUNCTIONS
Serotonin, an important brain neurotransmitter, is key
in the regulation of appetite, mood, and melatonin
production. The presence of serotonin in the brain is
associated with a balanced emotional state. This is
achieved in part by decreasing the activity of certain
excitatory hormones, including dopamine and
noradrenaline. Serotonin also acts as a satiety signal
in the brain, thereby naturally regulating food intake.
Additionally, as a precursor of melatonin, serotonin is
involved in regulating sleep patterns. Serotonin
is unable to cross the blood-brain barrier and is
therefore synthesized in the brain. Tryptophan, an
essential amino acid, is a precursor for the synthesis
of serotonin. Tryptophan crosses the blood-brain barrier
and is converted to L-5-hydroxytryptophan, which in turn
is converted into serotonin. Unfortunately, tryptophan
faces many obstacles during its journey into brain
tissue. First, dietary intake directly affects
body levels of tryptophan, as the body can not
endogenously produce it. High protein diets often
provide greater amounts of tryptophan, yet higher
carbohydrate diets appear to enhance tryptophan uptake
into the brain. Secondly, tryptophan must compete with
other amino acids for entry into the
brain. Finally, tryptophan may be taken up by other
tissues for protein or niacin synthesis, and thus is not
exclusively for use by the brain. As a metabolic
intermediate in the conversion of tryptophan into
serotonin, 5-HTP can also serve as a precursor of
serotonin. 5-HTP offers a number of advantages over
tryptophan. 5-HTP is derived naturally from the seeds of
the Griffonia plant, unlike
tryptophan which is produced synthetically or through
bacterial fermentation. 5-HTP crosses into the brain
more readily than tryptophan as it is able to cross the
blood-brain barrier without competition for uptake.
5-HTP is significantly more effective than tryptophan;
one 50 mg capsule of 5-HTP is roughly equivalent to
500 mg of tryptophan. Finally, research studies have
shown 5-HTP to be safe at levels as high as 900 mg.
As a result, 5-HTP is a safe and effective means of
increasing brain serotonin levels.
INDICATIONS
5-HTP Plus Formula capsules may be a useful nutritional
supplement for individuals wishing to obtain the
benefits of this well-documented plant extract to
increase their levels of brain serotonin.
FORMULA (#85073)
Each Vegetarian Capsule Contains:
L-5-hydroxytryptophan ................................75
mg.
Pyridoxal-5-Phosphate...........................7.5 mg.
Proprietary
Blend...........................................50 mg.

SUGGESTED USE
One to two capsules per day, between meals or as
directed by a physician. Vitamin B6 is necessary for the
conversion of 5-HTP to serotonin. Thus, an
adequate intake of vitamin B6 is necessary to derive
optimal benefits of 5-HTP.
