Metabolife 356 Information
Related Brand Names: Metabogenic
Metabolife 356 is the main thermogenic weight-loss pill of
Metabolife International. Metabolife 356 contains a proprietary
blend of guarana, ma huang, Siberian ginseng, ginger and seven
other herbs. It also contains spirulina, lecithin, bovine
complex, chromium picolinate, zinc, magnesium and vitamin
E.
The most active ingredients in Metabolife 356 are ephedrine
and caffeine. Like other ephedrine/caffeine-based products,
Metabolife 356 works by inducing thermogenesis (the production
of heat), which speeds up your metabolism and burns calories.
It also has an appetite-suppressing effect, so you feel less
hungry and therefore eat less.
Thus, Metabolife 356 works on two fronts:
- thermogenesis: 'speeding up' you metabolism, and making
you burn more calories
- appetite suppression: making you eat less, and forcing
the organism to mobilise the supplies it already posseses
- ie. use up fat.

How Does Metabolife 356 Work?
Metabolife 356 contains a variety of nutrients that helps
you to lose weight through different mechanisms. But the main
ingredients that produce its fat-burning effects are ephedrine
and caffeine. Studies have shown that when these ingredients
are combined in fairly specific ratios - 200 mg caffeine to
20 mg ephedrine (two or three times daily) - the results are
synergistic. In other words, the effects of each are greater
than the sum of their individual effects.
Here is a breakdown of the individual ingredients in Metabolife
356 and what they do:
Ephedra in Metabolife 356
Ephedrine is the primary fat-burning chemical in the Ephedra
sinica plant, from which it gets its name. Also known as ma
huang, this plant has a long history of usage in Asian countries
for the treatment of asthma and other bronchial conditions.
A related chemical, pseudoephedrine, is also found in the
plant and is an ingredient in many cold and flu remedies.
Ephedrine is a stimulant that works on the adrenergic receptors
of the central nervous system. It has been shown to increase
the level of dopamine, which is a precursor to both epinephrine
and norepinephrine, which are vital neurotransmitters. Dopamine
is also an important neurotransmitter around the hypothalamus,
an area of the brain that is important for body arousal. Unlike
caffeine, which exerts many of its benefits in muscle tissue,
ephedrine appears to work primarily on the central nervous
system.
Ephedrine inhibits the reuptake of norepinephrine, a hormone
secreted by the medulla of the adrenal glands, that acts as
a neurotransmitter. The sympathetic nervous system functions
in response to short-term stress; hence norepinephrine increases
the heart rate as well as blood pressure. Other actions of
norepinephrine include increased glycogenolysis (the conversion
of glycogen to glucose) in the liver, increased lipolysis
(the conversion of fats to fatty acids) in adipose (fat) tissue,
and relaxation of bronchial smooth muscle to open up the air
passages to the lungs. All of these actions represent a mobilization
of the body's resources in order to meet the stressful challenge;
such a response is often termed the 'flight or fight' syndrome.
Basically, ephedra in Metabolife 356 keeps your body in 'combat'
mode for extended periods of time, facilitating weight loss.
Ephedrine is an effective fat burner on its own, and when
it is combined with caffeine, the effects are even greater.
While the reasons for this are still not known, it is thought
that caffeine has a "permissive" action on ephedrine, lowering
the amounts needed to achieve its physiological effects. In
other words, caffeine potentiates ephedrine's effect. The
E/C studies that showed the greatest benefits used a 10:1
ratio of caffeine to ephedrine.
Caffeine in Metabolife 356
The caffeine source in Metabolife 356 is guarana seed extract.
Guarana is a bushy tree that grows in the Amazon rainforest.
Known botanically as Paullina cupana, it is almost as popular
as coffee in Brazil. Guarana does not have as much acid as
coffee, so it can be less irritating to the stomach than coffee
can. Guarana also has epicathechin and proanthocyanidins,
both of which are powerful antioxidants that help reduce free-radical
damage in cells. Epicathechin is chemically related to epigallocatechin
gallate (EGCG), which prolongs the life of norepinephrine.
As a result, the epicathechin may keep the thermogenic process
going for a even longer period of time, further boosting your
metabolic rate and facilitating fat loss.
As far as fat burning is concerned, the primary active ingredient
in guarana is caffeine. This plant chemical is rapidly absorbed
by the body and remains in circulation for more than seven
hours. Plasma concentrations reach a peak one hour after it
is consumed. It is then slowly metabolized, with a half-life
of four to six hours.
Caffeine has been shown to dramatically increase free fatty-acid
levels, providing the body with a fuel source that it can
use instead of the glycogen stored in your liver and muscles.
In fact, one study found a 100% increase in plasma free fatty
acids after the subjects took 330 mg of caffeine.
At the same time, caffeine has been shown to increase adrenaline
levels. This "fight-or-flight" hormone increases alertness
and boosts energy levels, helping you to go through your daily
tasks with less food intake. Most people experience a reduced
appetite when their adrenaline levels are high, usually because
they are focused on more essential tasks. With these two mechanisms,
it's easy to understand why caffeine is an important ingredient
in Metabolife 356 for jump-starting your weight-loss efforts.
Ginger root in Metabolife 356
Ginger (Zingiber officinale) is indigenous to tropical Asia
and is now cultivated in tropical areas throughout the world.
The rhizome, which is technically an underground stem instead
of a root, contains oleoresins that are rich in gingerols.
These compounds have a variety of sedative effects. Ginger
is traditionally used to calm the stomach and as a treatment
for motion sickness. Since some individuals experience gastrointestinal
upset with caffeine and other stimulatory chemicals, ginger
should help to eliminate this occasional Metabolife 356 side
effect. Ginger does not have any fat-burning properties.
Siberian ginseng in Metabolife 356
Siberian ginseng (Eleutherococcus senticosis) has a well-deserved
reputation as an adaptogen. This means that it helps the body
to deal with stress, including
the stress caused by a diet and exercise
program. Siberian ginseng has been shown to reduce the secretion
of cortisol in the adrenal glands. Cortisol is a catabolic
hormone that can eat away at muscle tissue, so it is best
to keep it under control. Siberian ginseng also promotes the
health of the adrenal gland while strengthening the immune
system and helping the body fight inflammation. The quantity
of Siberian ginseng in this formulation is not indicated.
Chromium picolinate in Metabolife 356
Chromium is a mineral that helps insulin bind to its receptor
sites. It is also involved in the metabolism of glucose for
energy. A deficiency of chromium can lead to increased fat
storage, fatigue, sugar cravings and mood swings, all of which
are counterproductive to your weight-loss goals. The average
Westerner does not get close to enough chromium, so supplementation
is often required. Getting your chromium in a fat burner is
as good as buying and consuming it separately.
The picolinate part of the molecule increases the bioavailability
of the chromium compared to the pure metal. While there is
a lot of propaganda about the supposed advantages of specific
carrier molecules, no comparative research has ever been done.
All of the commonly available forms of chromium supplements,
including the chromium in Metabolife 356, are sufficiently
bioavailable to eliminate any deficiency of this mineral that
you may have. What about Myogenix
Metabolife Results From Other ingredients
The five Metabolife 356 ingredients described so far in this
section are the ones that will provide virtually all of the
benefit from this product. The remaining nutrients are either
unproven or are - in all likelihood - included in such low
dosages that they will not burn significant amounts of fat
(even if they would have worked if taken in larger quantities).
Since the amounts of each nutrient in the proprietary blend
are not specified, it is impossible to say for sure.
Lecithin was once popular as a fat-burning agent back before
the ephedrine/caffeine blend became popular. It helps to metabolize
fatty acids, but this is normally not a limiting factor in
fat loss. As a result, you are not likely to experience any
benefit from it. Bovine complex is completely ambiguous. It
comes from a cow, but what part of the cow is unknown. Even
if it's glandular extracts, it's no going to help you burn
fat. The spirulina and seven additional herbs in Metabolife
356 have a variety of benefits in promoting general health,
as do the vitamins and minerals. However, there is no evidence
that they contribute to thermogenesis or fat loss in any appreciable
way.
How To Take Metabolife 356 and Metabolife 356 Dosage
and Administration
Take 2 Metabolife 356 tablets 2 or 3 times per day on an
empty stomach 1 hour before meals. Do not exceed 8 tablets
per day.
