means that taking L-tryptophan will result in producing
less serotonin than after supplementing with 5-HTP. Both
L-Tryptophan and 5-HTP must cross the blood-brain
barrier to make serotonin in the brain. However, unlike L-
Tryptophan 5-HTP doesn’t have to compete with other
amino acids to cross the blood-brain barrier. As a result 5-
HTP is much more e ective in getting into brain than it is
in case of L-tryptophan. For this reason 5-HTP is regarded
as signi cantly more e ective form of tryptophan in
boosting brain serotonin levels. Human body uses L-
tryptophan to produce a number of compounds including
Niacin (Vitamin B3), but 5-HTP is only used to produce
serotonin and melatonin (from serotonin). Your body can
convert L-Tryptophan and 5-HTP to serotonin in the liver
and also in the brain. When Part of L-tryptophan can be
converted to serotonin in the liver and this serotonin can’t
be used by the brain to improve mood or prevent
migraine.
While supplementing with L-tryptophan and 5-HTP it is
also very important to make sure that the rst is taken
with vitamin B3 and the second with vitamin B6.
Tryptophan is crucial in boosting serotonin levels because
serotonin is made in the body from tryptophan.
Tryptophan is rst converted in the liver into 5HTP (5-
Hydroxy L-Tryptophan) by the enzyme tryptophan
hydroxylase with the help of vitamin B3 (niacin). The
problem, however, is that when the liver attempts to
convert tryptophan to 5HTP in the absence of adequate
levels of vitamin B3, it will use tryptophan to synthetize it,
and it uses 60mg of tryptophan to produce 1mg of niacin,
thus leading to tryptophan and serotonin de ciency! That
is why if L-tryptophan supplements are taken instead of 5-
HTP it should be used with B3. On the other hand, when 5-
HTP gets into the liver another enzyme (decarboxylase)
converts it to 5HT, but it can do it e ectively only with the
help of vitamin B6 (pyridoxine). Unfortunately, when body
is de cient in this vitamin, liver will convert 5HTP to some
toxic metabolites! For this reason 5-HTP, which
e ectiveness in boosting serotonin levels is higher than
