How many people do
you know who have an insatiable carbohydrate craving or engage in binge
eating? I believe one of the reasons we see so many obese people around is
that they're deficient in L-Tryptophan. Tryptophan, an amino acid, is the
only dietary raw material that the brain can use to produce the neurotransmitter
serotonin. Low levels have been linked to not only diet control issues,
but depression, anxiety, and disturbed sleep. Now you can have the safest,
purest form of tryptophan found anywhere in today's market. That's why I
take this every night. - Peter
L-Tryptophan is an essential amino
acid, which means it cannot be synthesized by the human body and therefore must
be part of the diet or supplementation. The best sources for tryptophan are
high-protein foods such as oats, bananas, dried dates, dairy products, fish,
many nuts, and poultry.
Tryptophan is critical in helping your body
produce proteins for muscle, hair, and skin. Unfortunately, tryptophan is
the least abundant amino acid in your diet. Even a person on a high-protein diet
gets less than 1.5 grams of tryptophan a day. What’s more, when you ingest
tryptophan it undergoes degradation processes that dramatically reduces the
amount actually available for conversion to serotonin in the brain. Some experts
estimate that only 1% of the dietary tryptophan you take in reaches the brain.
For some this is sufficient, but for others, low levels can adversely affect
sleep, weight, and mood.
Tryptophan is a precursor for serotonin.
Unlike other products that influence serotonin reuptake, L-tryptophan is a
direct precursor that results in almost immediate increases in serotonin, which
is one of the primary neurotransmitters involved with sleep and mood.
In those people with low serotonin levels,
L-tryptophan has been shown to help establish and maintain healthy levels, which
may help to improve mood9
and reduce tension. In those people with serotonin levels already within
the normal range, L-tryptophan acts as a natural sleep aid, not only helping
people fall asleep,10-13 but also helping them stay asleep throughout the
night and wake without grogginess. For this reason, some experts believe
tryptophan can be a safe and effective sleep aid when added to your diet as a
supplement. Supplementing your diet with tryptophan, specifically TryptoPure™,
may mean a more restful night’s sleep, a brighter mood, and a host of other
benefits.
Life Extension has selected TryptoPure™ as

Vitamin B6 is an essential cofactor in
the conversion of L-tryptophan to serotonin in the body, while niacinamide
plays an important role in enabling the body to properly utilize amino
acids like tryptophan. Therefore, those taking L-tryptophan may find
optimal results by consuming a B-complex supplement during the day that
provides at least 50 mg of niacinamide and 50 mg of vitamin B6.
| | | Caution | |
Serotonin syndrome is characterized by high
levels of serotonin and symptoms like confusion, sweating, agitation, nausea,
involuntary muscle contractions, and racing heartbeat. Do not take L-tryptophan
if you experience these symptoms. Do not take L-tryptophan in combination with
other agents that increase serotonin levels in the central nervous system.
Agents that increase serotonin levels can include psychiatric medications (e.g.,
antidepressants, lithium), migraine medications (e.g., sumatriptan), Parkinson’s
disease medications (e.g., carbidopa), and dextromethrphan, an over-the-counter
cough suppressant. Do not use before driving or operating heavy
machinery. | | Warnings |
