What is 5-HTP?
5-Hydroxytryptophan (5-HTP) is an amino acid that is the
intermediate step between tryptophan and the important brain chemical
serotonin. There is a massive amount of evidence that suggests that low
serotonin levels are a common consequence of modern living. The
lifestyle and dietary practices of many people living in this
stress-filled era results in lowered levels of serotonin within the
brain. As a result, many people are overweight, crave sugar and other
carbohydrates, experience bouts of depression, get frequent headaches,
and have vague muscle aches and pain. All of these maladies are
correctable by raising brain serotonin levels.
What is the best way to take 5-HTP?
For depression, weight loss, headaches, and fibromyalgia the
dosage should be started at 50 mg three times per day. If the response
is inadequate after two weeks, increase the dosage to 100 mg three
times per day. This recommendation will greatly reduce the mild
symptoms of nausea often experienced during the first few weeks of
5-HTP therapy. Because 5-HTP does not rely on the same transport
vehicle as L-tryptophan, it can also be taken with food. But, if you
are taking 5-HTP for weight loss it should be taken 20 minutes before
meals.
What is the Evidence for 5-HTP?
Depression
Several small clinical trials have found that 5-HTP is as
effective as antidepressants. For example, in a six week clinical
trial, 63 people were given either 5-HTP (100 mg three times a day) or
an antidepressant (fluvoxamine, 50 mg three times a day). The 5-HTP was
found to be as effective as the antidepressant, with fewer side effects.
Migraine
Some research indicates that 5-HTP may prevent migraines and reduce the
frequency and severity of migraines, however large randomized
controlled trials are needed.
In one study, 124 people were given 5-HTP (600 mg/day) or the drug
methysergide. After 6 months, 5-HTP was found to be as effective as
methysergide in reducing the severity and duration of migraines.
Another study looked at 5-HTP or the drug propranolol for 4
months. Both treatments resulted in a statistically significant
reduction in the frequency of migraines. However, the propranolol group
fared better, with a reduction in the duration of episodes and the
number of analgesics used for the treatment of episodes.
Fibromyalgia
Fibromyalgia is a chronic condition characterized by fatigue,
widespread pain in the muscles, ligaments and tendons, and multiple
tender points.
A double-blind, placebo controlled study looked at 5-HTP or
placebo in 50 people with fibromyalgia. After four weeks, there was
improvement in pain, stiffness, anxiety, fatigue, and sleep. Side
effects were mild and transient.
Insomnia
Serotonin is converted into melatonin, a hormone need to regulate
sleep-wake cycles. Because 5-HTP is thought to increase serotonin
levels, it may increase melatonin and help normalize sleep patterns
5-HTP against depression?
Yes. In fact, there is excellent documentation that 5-HTP is an
effective antidepressant agent. 5-HTP often produces very good results
in patients who are unresponsive to standard antidepressant drugs. One
of the more impressive studies involved 99 patients described as
suffering from "therapy resistant" depression. These patients had not
responded to any previous therapy including all available
antidepressant drugs as well as electro convulsive therapy. These
therapy resistant patients received 5-HTP at dosages averaging 200 mg
daily but ranging from 50 to 600 mg per day. Complete recovery was seen
in 43 of the 99 patients and significant improvement was noted in 8
more. Such significant improvement in patients suffering from
long-standing, unresponsive depression is quite impressive prompting
the author of another study to state "5-HTP merits a place in the front
of the ranks of the antidepressants instead of being used as a last
resort. I have never in 20 years used an agent which: (1 was effective
so quickly; (2 restored the patients so completely to the persons they
had been and their partners had known; [and] (3 was so entirely without
side effects)".
What effect does 5-HTP have on weight loss?
As far back as 1975, researchers demonstrated that administering 5-HTP
to rats that were bred to overeat and be obese resulted in significant
reduction in food intake. It turns out that these rats have decreased
activity of the enzyme that converts tryptophan to 5-HTP and
subsequently to serotonin. In other words, these rats are fat as a
result of a genetically determined low level of activity of the enzyme
that starts the manufacture of serotonin from tryptophan. As a result,
these rats never get the message to stop eating until they have
consumed far greater amounts of food than normal rats.
There is much circumstantial evidence that many humans are genetically
predisposed to obesity. This predisposition may involve the same
mechanism as that observed in rats genetically predisposed to obesity.
In other words, many people may be predisposed to being overweight
because they have a decreased conversion of tryptophan to 5-HTP and, as
a result, decreased serotonin levels. By providing preformed 5-HTP,
this genetic defect is bypassed and more serotonin is manufactured.
5-HTP literally turns off hunger.
The early animal studies that used 5-HTP as a weight loss aid have been
followed by a series of three human clinical studies of overweight
women, conducted at the University of Rome. The first study showed that
5-HTP was able to reduce caloric intake and promote weight loss despite
the fact that the women made no conscious effort to lose weight. The
average amount of weight loss during the five-week period of 5-HTP
supplementation was a little more than 3 pounds.
The second study sought to determine whether 5-HTP helped overweight
individuals adhere to dietary recommendations. The twelve-week study
was divided into two six-week periods. For the first six weeks, there
were no dietary recommendations; for the second six weeks the women
were placed on a 1,200-calorie diet. As shown in Table 1, the women who
took the placebo lost 2.28 pounds, while the women who took the 5-HTP
lost 10.34 pounds. As in the previous study, 5-HTP appeared to promote
weight loss by promoting satiety-the feeling of satisfaction-leading to
fewer calories being consumed at meals. Every woman who took the 5-HTP
reported early satiety.
In the third study involving 5-HTP, for the first six weeks there were
no dietary restrictions, and for the second six weeks the women were
placed on a 1,200-calorie-per-day diet. The results from this study
were even more impressive than the previous studies for several
reasons. The group that received the 5-HTP had lost an average of 4.39
pounds at six weeks and an average of 11.63 pounds at 12 weeks. In
comparison, the placebo group had lost an average of only 0.62 pounds
at six weeks and 1.87 pounds at twelve weeks. The lack of weight loss
during the second six-week period in the placebo group obviously
reflects the fact that the women had difficulty adhering to the diet.
Early satiety was reported by 100 percent of the subjects during the
first six-week period. During the second six-week period, even with
severe caloric restriction, ninety percent of the women taking 5-HTP
reported early satiety. Many of the women who received the 5-HTP (300
mg three times per day) reported mild nausea during the first six weeks
of therapy. However, the symptom was never severe enough for any of the
women to drop out of the study. No other side effects were reported.
Fibromyalgia and Migraines.....how does 5-HTP help?
The history of the development of
5-HTP as an effective
treatment for fibromyalgia began with studies on the drug fenclonine.
This drug blocks the enzyme which converts tryptophan to
5-HTP and as a
result blocks serotonin production. During the late 1960s and early
1970s, it was thought that increased serotonin formation may promote
migraine headaches (the opposite of what was later proved, i.e.,
increasing serotonin levels reduce migraine headache occurrence). The
researchers discovered that providing headache sufferers with
fenclonine resulted in very severe muscle pain. This effect was exactly
opposite of what was expected, but led to some important advances in
the understanding of fibromyalgia--a way to induce its severe symptoms
of (as well as symptoms nearly identical to EMS, the condition caused
by contaminated L-tryptophan). The researchers also discovered that
migraine sufferers reacted to the drug much more than non-headache
sufferers. In fact, in most normal subjects fenclonine produced no
fibromyalgia. These occurrences highlight just how sensitive migraine
sufferers are to low serotonin levels.
