Serotonin increase - Serotonin levels are increased by hydroxytryptophan (5-HTP)
Serotonin happens to be the most widely studied neurotransmitter since it helps
regulate a vast range of psychological and biological functions. Serotonin
(5-hydroxytryptamine or 5-HT) was first identified in 1948. The wide extent of
psychological functions regulated by serotonin involves mood, anxiety, arousal,
aggression, and thinking abilities. You may recall that other brain chemicals, such as
dopamine and norepinephrine, also influence mood and arousal. However, serotonin generally
has different effects. For instance, excess amounts of serotonin cause relaxation,
sedation, and a decrease in sexual drive.
Prozac, a common antidepressant, elevates
serotonin levels, and perhaps influences the levels of other brain chemicals. There is an
over-the-counter nutrient called 5-Hydroxytryptophan (5-HTP) that is the immediate
precursor to serotonin and can, in some cases, temporarily substitute for
serotonin-influencing drugs (see chapter 13). Some research suggests that perhaps the
herbal antidepressant St. Johns wort also works by elevating levels of serotonin in
the brain.
Disruption of the normal functioning of the serotonergic system leads to a number of psychiatric conditions, which include anxiety
disorders, depression, improper social behavior, and sexual aberrations. Common medical
conditions associated with disruption of the serotonergic system include disturbance in
the sleep-wake cycle, obesity or eating disorders, and chronic pain.
Suppliers of 5-HTP and natural supplements
5-HTP
is available online at low prices and you can purchase
5-HTP
at Physician Formulas. We don't suggest using 5-HTP the same day
as fluoxetine,
also known as Prozac, or the other SSRIs.

Side effects of Serotonin
One of the side effects of excess serotonin
is reduced sex drive. However, there are many natural herbs that can reverse
this process.
Selective Serotonin Reuptake drugs may lead to more bone fractures in older adults
The daily use of a selective serotonin reuptake inhibitor antidepressant
drugs such as Prozac, Zoloft, Paxil, and others increases the risk of fractures
in adults 50 years of age or older. Doctors who prescribe these serotonin drugs to older
patients should let them know of the risk and consider whether the benefits
outweigh the risks in cases of mild depression. The most common site of fracture
is the forearm, followed by ankle and foot.
Many people have benefited from the use of selective serotonin
reuptake inhibitor drugs. However these serotonin enhancing medications do have
several side effects and doctors have to balance the benefit versus the risks.
Natural antidepressants are a good option for those with mild or moderate
depression. They also have side effects but they are less serious.
The promise of serotonin
drugs in appetite suppression and weigh loss

Endogenous hypothalamic serotonin (5-hydroxytryptamine) plays an important part
in within-meal satiation and post-meal satiety processes. Thus, the serotonin
system has provided a viable target for weight control, critical to the action
of at least two effective anti-obesity treatments, both producing clinically
significant weight loss over a year or more. Numerous serotonin receptor
subtypes have been identified; of these, serotonin 5-HT(1B) and 5-HT(2C)
receptors have been specifically recognised as mediators of serotonin -induced
satiety. A number of serotonin drugs, including selective serotonin reuptake
inhibitors (SSRIs), dexfenfluramine and 5-HT(2C) receptor agonists, have been
shown to significantly attenuate rodent bodyweight gain. This effect is strongly
associated with marked hypophagia and is probably mediated by the hypothalamic
melanocortin system. Additionally, sibutramine, dexfenfluramine, fluoxetine and
the 5-HT(2C) receptor agonist chlorophenylpiperazine (mCPP) have all been shown
to modify appetite in both lean and obese humans, resulting in reduced caloric
intake. Clinical studies demonstrate serotonin drugs specifically reduce
appetite prior to and following the consumption of fixed caloric loads, and
cause a reduction in pre-meal appetite and caloric intake at ad libitum meals.
Weight loss in the obese has also been produced by treatment with both the
serotonin precursor
5-hydroxytryptophan 5-HTP and the preferential 5-HT(2C) receptor agonist mCPP.
Email Questions about
Serotonin
Q. Is it possible to measure the brains
serotonin levels via blood tests and if so, how accurate are the
results?
A. Most researchers find that levels of serotonin and other brain
chemicals are more accurately measured in spinal fluid as opposed to blood.
Q. Serotonin so far is helping me to sleep better
for a while. But I ve been seeing some nightmares. Should I take any other
formula, and it should not has a counter act with serotonin 5hp. Does serotonin
gives this effect of nightmare. But serotonin is helping me know about my eating
sleep disorder. Please advise me.
A. You mean 5HTP
or 5-HTP, right, not serotonin.
