L Tryptophan for
insomnia, stress relief, help with sleep, safety
L-Tryptophan is an essential amino
acid found in foods that contain protein and is able to convert
into 5-HTP (5-hydroxy-tryptophan), and then to
serotonin. Serotonin is
involved in mood, appetite, sleep and behavior. For a
product that helps with sleep, see
Good-Night-Rx. L-Tryptophan may reduce appetite in some individuals.

Behavior effect
Social behaviour and mood in everyday life: the effects of tryptophan in
quarrelsome individuals.
J Psychiatry Neurosci.
2006.
We hypothesized that increasing brain serotonin in healthy individuals
with high scores on 2 self-report measures of trait quarrelsomeness would
reduce quarrelsome behaviours and enhance agreeable behaviours when
measured ecologically using an event-contingent recording method. We
conducted a double-blind crossover study, in which participants took
l-tryptophan at 3 grams a day and placebo for 15 days each and recorded how
they behaved, felt and perceived others during everyday social
interactions. L-Tryptophan supplement use significantly decreased
quarrelsome behaviours and increased agreeable behaviours and perceptions
of agreeableness. Men also behaved less dominantly, whereas both men and
women perceived others as more dominant. L-Tryptophan's effects on
behaviours and perceptions, while more marked in the men, were generally
positive and accompanied by improved affect. Increasing serotonin in
quarrelsome people may not only reduce behaviours associated with a
predisposition to various mental and physical disorders but also enhance
socially constructive behaviours and improve social perceptions.
Sleep and insomnia
Dietary carbohydrate intake has been shown to increase the plasma concentration
of l-tryptophan, a precursor of serotonin and sleep-inducing agent.
Does this really work for insomnia? Wasn't
this amino acid banned just a few years ago? I assume it is now legal or you
would not be selling it. If I took this product should I take something in
addition to it? I have had insomnia for years, tried so many products and
nothing seems to work. I try to stay away from prescription drugs like Ambien
but sometimes I find that is the only thing that "knocks" me out.
Yes, it is now legal and some people find it helpful for
insomnia although those who are used to taking potent prescription sleeping
pills may not find it strong enough.
5-HTP or L
tryptophan, which is better?
5-HTP is also available over the
counter.
5-HTP converts into serotonin.
Use with SAM-e
natural antidepressant
Can i take Sam-e and L-Tryyophan
together for antidepression and sleep.
SAM-e causes alertness and interferes with sleep. L Tryptophan
can work well for sleep, but even better is Good Night Rx.
Gourd seed as a
source
Protein source tryptophan versus pharmaceutical grade tryptophan as an
efficacious treatment for chronic insomnia.
Nutr Neurosci. 2005.
Intact protein rich in tryptophan was not seen as an alternative to
pharmaceutical grade tryptophan since protein also contains large neutral amino
acids (LNAAs) that compete for transport sites across the blood-brain barrier
(BBB). Deoiled gourd seed (an extremely rich source of tryptophan - 22 mg
tryptophan /1 g protein) was combined with glucose, a carbohydrate that reduces
serum levels of competing LNAAs which was then compared to pharmaceutical grade
tryptophan with carbohydrate as well as carbohydrate alone. Subjects were
randomly assigned to one of three conditions: (1) Protein source tryptophan (deoiled
gourd seed) in combination with carbohydrate; (2) pharmaceutical grade
tryptophan in combination with carbohydrate; (3) carbohydrate alone. Protein
source tryptophan with carbohydrate and pharmaceutical grade tryptophan, but not
carbohydrate alone, resulted in significant improvement on subjective and
objective measures of insomnia. Protein source tryptophan with carbohydrate
alone proved effective in significantly reducing time awake during the night.
Protein source tryptophan is comparable to pharmaceutical grade tryptophan for
the treatment of insomnia. For information on natural
insomnia cures.
Metabolism and
biochemistry
L-Tryptophan converts into
Hydroxy tryptophan, which then readily converts into
serotonin which has a brain and mood
influence, there are several nutrients that increase serotonin levels. Once serotonin is made, the pineal gland is able to convert it at night into
melatonin, the sleep-inducing hormone.
Pregnancy
I am very interested to use 5 HTP and Tryptophan supplements. My
question is if can I use both products if I am pregnant? I actually take Prozac
because I have a big problem with serotonin.
We are not aware of any human studies in women who are pregnant
who have been placed on long term 5-HTP or tryptophan supplement treatment.
Since we don't know if these supplements are safe during pregnancy, we cannot
advise them to be used.
Interactions
with medications
Is it safe to take tryptophan with Tofranil?
Tofranil, imipramine hydrochloride USP, the original
tricyclic antidepressant, is a member of the dibenzazepine group of compounds.
It is not easy to predict interactions between medications and supplements and
dosage has a major factor.
The
history
During the 1980s consumers were using l-tryptophan for sleep and as
an antidepressant. L-Tryptophan was available without prescription until 1989 when the FDA prohibited its
over-the-counter sale because a l-tryptophan manufacturer in Japan shipped a contaminated
batch to the U.S. This caused a serious illness called eosinophilia myalgia syndrome
in about 1,000 individuals.
Around
1995,
l-tryptophan gradually became available by prescription through compounding
pharmacies, and then since about the year 2000 l-tryptophan slowly and cautiously was
placed on the over the counter market through a few small vitamin companies. Few
large vitamin companies are selling l-tryptophan at this time (2008).
questions
I am 98 Kg and had no food 3
hours before taking it.
I took 4 tryptophan capsules with water and was still awake after 3 hours. I
took 2 more capsules still could not sleep.
One hour later I took 2 more capsules and have been awake all night and could
not sleep. I took a total of 8 capsules and the L-Tryptophan and it had no
effect on me. Does it take a while to get into your system.
Sometimes taking too much of a certain herb or supplement can
cause stimulation as opposed to sedation. It is better to stay with 500 mg of
l-tryptophan a few hours before bed. A better option for sleep is Good Night Rx
which is much more consistent.
Q. I was just wondering why the directions
on a l-tryptophan web site say to take only 4 days a week. I work nights, and have
a horrible time sleeping, expecially when I am off.
A. Tolerance can develop to most pills used for sleeping, therefore it is better not to use them every night so that their
benefit continues longer. Some people can take Good Night Rx 2 or 3 times a week
as a substitute for the times a l-tryptophan supplement is not taken. However, it
is still best not to take a pill every night of the week.
Q. I currently take a tryptophan
supplement at night but would like to try taking part of my dosage in the
morning to see if more of it might convert to serotonin. I have a thyroid
problem. I am hypothyroid and take 112mcg of Synthroid each morning. Would it be
ok to take both the Synthroid and tryptophan in the morning before eating?
A. This is a question for your doctor since different people may
respond differently. When adding a new supplement, it is often a good idea to
first use a low dosage even if it requires taking a portion of a capsule.
Q. Does Taking 4000 mg of Tryptophan per
day( overdosing) for a long period of time harmful? A doctor told me that it
would cause stiffness in the tissues and even bleeding internally. I was
wondering would it be harmful to take 500 mg of tryptophan per day for a period
of 1 year? Also how much of tryptophan gets converted to serotonin comparing to
5-htp?
A. Tryptophan converts to 5-HTP which converts to serotonin.
Therefore, much less 5-HTP is needed to convert to serotonin that tryptophan.
The exact percentage of conversion of tryptophan to serotonin varies among
individuals and it can vary depending on time of day and whether there is food
in the stomach or not. There are many variables that influence the conversion of
tryptophan to 5htp to serotonin so there is no simple answer. Plus, different
tissues and organs of the body may have a different conversion rate.
Long term human studies with high dose tryptophan supplements are
not available to know the safety and danger or long term tryptophan side
effects. It is a good idea, until we learn more, to limit the use of tryptophan
supplements to 5 days a week with a week off each month. This is just a rough
guideline.
I'm curious whether I can take the three
supplements I am ordering at the same time...Tryptophan, Passion Rx and
Resveratrol. I'm 60, take only vitamins and have no medical condition. Plan to
take only low dosage.
We suggest taking them separately for a few days before
considering combining them.
Can 5 HTP boost levels of norepenephrine: what other supplements do? Are L tryptophan
and 5HTP ever taken together? What's the difference? From what I've read &
learned it seems, L tryptophan is more connected with serotonin, than
noreprenephrin.
5-HTP has more of an effect on serotonin levels, its actions
are similar to and overlap with tryptophan, if both are taken together the
dosages need to be reduced. Tyrosine and phenylalanine are more likely to effect
norepinephrine levels.
I have read that when taken in the
morning, tryptophan will be converted to seratonin, but when taken at night,
tryptophan will be converted to melatonin. Therefore, if tryptophan is being
taken for depression, would taking it in the morning rather than the night be
advisable?
Before converting to melatonin, tryptophan converts into serotonin.
Most people find mood elevating properties of this amino acid whether taken
during the day or evening but most people find it to be effective taken in the
evening.
Thank you for your informative website, I
am interested in some of natural products but wanted to ask a question about an
interaction I had had with a different product because I want to avoid it
happening again if I try something else. After doing some research I decided to
take 500mg of tryptophan (Jarrow brand I think) to begin with before bed,
doubling up to 1g after a couple of nights. It worked well at first, however
after a few nights as I was drifting off to sleep I felt an electrical buzzing
sensation at the front of my head, which came in waves and kept me awake all
night. Needless to say I stopped taking this but it has left me wondering
whether it was a poor quality product or whether this was a unique interaction
with my chemistry. I appreciate you can't offer medical advice on my individual
circumstances but I wonder if you could comment generally on this type of side
effect and whether their are other types of amino acids I should avoid.
Sometimes taking too high a dosage of a supplement can cause
unexpected reactions, and some people have reported this kind of strange
sensation with 5-htp or tryptophan.
I am currently taking tryptophan, gaba,
sedaplus and melatonin to help me sleep. Also one of my other supplements is
methionine. I was wondering if any of those could help cause a amaurosis fugax.
Had it to happen last night. Couldn't really see out of one eye.... very dark
gray... lasted a few minutes. My eye felt strange as well. Went to optometrist
and things look ok. I saw something that a couple of these supplements could
cause vasospasms even in the eye. Have you all heard or know of such research? A
little afraid to continue with supplements.
We have not.
