This article first appeared in "Social Policy", Vol. 26, No.
2 Winter 1995. Dr. Manders has lectured and done extensive research
on the medical politics of L-Tryptophan. The article also appeared
in "Blazing Tattles" June 1996.
In the fall of 1989, the FDA recalled L-Tryptophan, an amino acid nutritional
supplement, stating that it caused a rare and deadly flu-like
condition (Eosinophilia-Myalgia Syndrome / EMS). On March
22, 1990, the FDA banned the public sale dietary of L-Tryptophan
completely. This ban continues today. On March 26, 1990, "Newsweek"
featured a lead article praising the virtues of the anti-depressant
drug Prozac. Its multi-color cover displayed a floating, gigantic
green and white capsule of Prozac with the caption: "Prozac:
A Breakthrough drug for Depression." The fact that the FDA ban of L-Tryptophan and the Newsweek Prozac cover
story occurred within four days of each other went unnoticed
by both the media and the public. Yet, to those who understand
the effective properties of L- Tryptophan and Prozac, the
concurrence seems "unbelievably coincidental." The link here
is the brain neurotransmitter serotonin---a biochemical nerve
signal conductor. The action of Prozac and L-Tryptophan are
both involved with serotonin, but in totally different ways. Elevated levels of serotonin in the body often result in the relief of
depression, as well as substantial reduction in pain sensitivity,
anxiety and stress. Prozac, as well as other new anti-depressant
drugs such as Paxil and Zoloft, attempt to enhance levels
of serotonin by working on whatever amounts of it already
exists in the body (these drugs are known as selective serotonin
reuptake inhibitors). None of these drugs, however produce
serotonin. In contrast, ingested L-Tryptophan acts to produce
serotonin, even in individuals who generate little serotonin
of their own. The most effective way to elevate serotonin
would be to use a serotonin producer rather than a serotonin
enhancer. The continuing FDA public ban of L-Tryptophan prevents popular access
to this most effective serotonin producer. The millions of
Americans who for decades safely have relied upon L-Tryptophan
to relieve depression, anxiety and PMS, as well as to control
pain and induce natural sleep, have been forced elsewhere
for solutions. Routinely, such solutions are pharmaceutical in nature: people are forced
to use either often highly addictive, expensive, and sometimes
dangerous drugs like Xanax, Valium, Halcion, Dalmane, Codeine,
Anafranil, Prozac, and others, or simply suffer. Present FDA
public policy maintains that L-Tryptophan is an untested,
unapproved and hazardous drug. The analytical work done a
few years ago by the Centers for Disease Control and the Mayo
Clinic, research which traced the fall of the serious flu-like
condition to contaminants found in batches of L-Tryptophan
made by the Japanese company Showa Denko, has not convinced
the FDA to allow L-Tryptophan back on the market. This decision
is based primarily on the research of FDA and NIMH scientists
who state that L- Tryptophan itself, irrespective of contaminants,
is a dangerous substance. Other university-based research
scientists disagree with these findings. The public availability of L-Tryptophan is too important an issue only
to be argued and shrouded within scientific debate that remains,
ultimately, mystifying to the vast majority of Americans.
There are many obvious facts worthy of public attention, and
concern. For example, consider the following: On February 9, 1993, a United States
government patent (#5185157) was issued to use L-Tryptophan
to treat, and cure EMS, the very same deadly flu-like condition
which prompted the FDA to take L-Tryptophan off the market
in 1989. Notwithstanding its public ban and import alert on L-Tryptophan, the FDA
today allows Ajinomoto U.S.A. the right to import from Japan
human-use L- Tryptophan. Distributed from the Ajinomoto in
Raleigh, North Carolina, the L- Tryptophan is then sold to,
and through, a network of compounding pharmacies across the
United States. Purchased by individuals only under a physician's
order, L-Tryptophan emerges here as a new prescription drug
in the serotonin marketplace; one hundred 500 mg. capsules
cost about $75.00, approximately five times more than if they
were sold as a dietary supplement. Since the FDA holds the political mandate and power of a public regulatory
agency established ostensibly, to protect people from raw
corporate interests in drug production and distribution, the
actions of the FDA in concert with Ajinomoto U.S.A. are illuminating.
By publicly banning L-Tryptophan from its dietary supplement
status and price, while allowing L-Tryptophan to be sold as
a high-priced prescription drug, the naked duplicity of the
FDA L-Tryptophan policy is revealed. During and after the 1989 EMS outbreak, the FDA did not totally ban the
use of L- Tryptophan in humans---then, as today, the FDA has
granted the pharmaceutical industry the protected right to
use L-Tryptophan in hospital settings. Manufactured by Abbott
Laboratories, the amino acid injectable solutions Aminosyn
and Aminosyn II contain as much as 200 mg. of L-Tryptophan.
(Moreover, L-Tryptophan has never been removed from baby food
produced and sold within the United States.) While the FDA
has banned the public sale and use of safe, non-contaminated,
dietary supplements L-Tryptophan for people, the United States
Department of Agriculture still sanctions the legal sale and
use of non-contaminated L-Tryptophan for animals. Today, as
in the past, feed grade L-Tryptophan continues to be used
as a nutritional and bulk feed additive by the commercial
hog and chicken farming industry. Additionally, L- Tryptophan
is now available for use by veterinarians in caring for horses
and pets. Outside of the United States, in countries such as Canada, the Netherlands,
Germany, England, and others, L-Tryptophan is widely used.
Nowhere, have any serious or widespread health problems have
occurred. At bottom, the FDA public ban of safe, non-contaminated L-Tryptophan is
uneven, expensive, and biased in favor of the pharmaceutical
industry. The FDA proscription effectively awards billions
of dollars in profits to pharmaceutical companies and their
suppliers in the same proportion as it adds billions of unnecessary
dollars to the nation's already bloated health care expenditures. On June 15, 1993, the FDA Dietary Supplement Task Force published a report
on the work it had been doing in the area of developing FDA
policy around nutritional supplements. On page two, the report
admits, "The Task Force considered various issues in its deliberations,
including ... what steps are necessary to ensure that the
existence of dietary supplements on the market does not act
as a disincentive for drug development." In this case, the FDA has succeeded in carrying out its stated policy
goal. With competition from publicly available L-Tryptophan
removed, the rapidly expanding market in prescription serotonin
drugs---now among them L-Tryptophan itself---contains no major
"disincentives" for the massive accumulation of pharmaceutical
industry profits. It is now time for appropriate congressional committees to review openly
and aggressively the entire matter of L-Tryptophan. This will
provide a needed forum where political, corporate, and scientific
issues of the FDA L- Tryptophan regulatory policy may be addressed.
There exists ample precedent for such hearings: in the 1980's
and early 1990's, for example, such investigations uncovered
favoritism in the approval of generic drugs and the bribery
of FDA officials. The story of L-Tryptophan illustrates a sad perverse picture of the politics
and priorities of public health in America: A safe, dietary-supplement
serotonin producer is publicly unavailable to people, while
daily fed to animals by corporate agribusiness. A patent is
approved to use L-Tryptophan to cure the very condition the
FDA claims it caused. And, while publicly exclaiming that
L-Tryptophan is a dangerous and untested drug, the FDA more
quietly, allows human-use L-Tryptophan to be imported, and
then marketed and sold by the pharmaceutical industry. To allow the FDA ban of L-Tryptophan to continue unreviewed and univestigated
condemns millions of Americans to unnecessary financial expenditures
and needless suffering. Are you Dean Manders,or do you have his email address or know anyone who
does? I have a ton of info on this subject. The patent he
is discussing on L-tryptophan for the cure of eosinophilia
myalgia syndrome is held by Dr.Christopher Caston of Spartenburg
S.C. and info about his patent was published in two peer reviewed
medical journals at the exact same time the FDA banned l-tryptophan.
I have a transcript of the entire FDA run hearing on Dietary
Supplements which took place in the Masur Auditorium of NIH
on August 29th 1990 in which the FDA was shamelessly parading
eosinophilia myalgia victims up to the microphone for propaganda
purposes, in order to have them denounce the dietary supplement
industry over the Showa Denko contaminated tryptophan. (Showa Denko is a PHARMACEUTICAL company, and a really bad actor at that-
they once BLEW UP part of their plant to thwart a Japanese
government inspection which would have proved that they were
responsible for contaminating a river in Japan with mercury,
causing untold misery and suffering- kids born with birth
defects, etc, ad nauseum. The contaminated l-tryptophan was
caused by using genetic engineering to crank up a strain of
bacteria used in the fermentation process that the amino acid
is generated through. They wanted to make the stuff FASTER
than their competitors, and tossed GMPs out the window. At NIH these poor people were being plugged full of prednisone, and other
highly dangerous drugs, which did NOTHING to alleviate their
condition, while a patented, peer reviewed nutritional protocol
including l-tryptophan existed, to the FDA's knowledge, but
the FDA and NIH did not let these patients at NIH hospital
have it, because they wanted to use them as political pawns.
I can document everything I'm saying here because I testified
at that hearing and exposed the whole charade, and I have
the official government transcript of my testimony, along
with the proof of everything I said, stored in multiple locations
in case they ever burn my house down. You are right, there
should be a congressional investigation- but there never will
be unless we CRUSH congress with faxes about this. Anyone
want to?
