Trim Spa Reviews
The combination
of ephedrine and caffeine is a widely documented nutritional method
of inducing weight loss. Numerous studies have confirmed the effectiveness
of the ingredients in Trim Spa. For a
discussion of what results you can expect when taking Trim Spa,
see Trim Spa Results.
Like any fat
burner, Trim Spa is only as good as its ingredients. So Trim Spa
reviews includes a complete analysis of each of its fat-burning
ingredients.

Ingredients In Trim Spa
Ephedrine
and Caffeine
Renowned weight-loss expert Arne Astrup, MD, and his associates
performed a study with ephedrine at the University of Copenhagen
and two Danish hospitals. Five young females were given 20 mg
of ephedrine three times per day one hour before meals and were
told to continue eating normally. Even though there was no dieting
involved, the women lost an average of 2.5 kg of body weight after
four weeks and 5.5 kg after 12 weeks. They also held onto their
lean muscle, while their body-fat percentage dropped by 3.5% after
four weeks and 5.2% after 12 weeks. Two months after the experiment
stopped, they had only gained back 0.5 kg. The only side effect
was a mild rise in blood pressure at the start of the experiment.
Two studies by the same Danish researchers indicate the benefits
of combining ephedrine with caffeine. In both studies, the participants
took a supplement with 20 mg of ephedrine and 200 mg of caffeine
three times per day. They also followed a low-calorie diet. In
the first study, the test subjects lost 16.2% of their body weight
in 24 weeks, significantly more than the 13.4% loss by the placebo
group. The second study confirmed that most of this loss was body
fat. In that eight-week study, the E/C group lost 10.1 kg, compared
to only 8.4 kg with the placebo. But the E/C group lost twice
as much fat (9.0 kg vs. 4.5 kg) and much less fat-free mass (1.1
kg vs. 3.9 kg). Only mild side effects were reported.
The E/C combination has been extensively studied, but space limitations
do not allow a detailed listing of the many studies that have
showed benefits. All of this research, however, supports the effectiveness
of the E/C stack and demonstrates the moderate level of side effects
when you take appropriate dosages. (For more information on the
side effects of Trim Spa, see Trim
Spa side effects.)
L-tyrosine
Research suggests that supplementing with tyrosine may minimize
the degradation of the neurotransmitters involved in the metabolic
process while enhancing the thermogenic effects of the ephedrine/caffeine
stack. With more raw material available, the neurotransmitters
controlling metabolism are produced at a higher level with beneficial
results. The increases in alertness and energy level will also
make it easier to stick to your diet program.
Ginger root
Ginger has a long history of use as a treatment for motion sickness.
In one double-blind, placebo-controlled study by Danish researchers,
naval cadets unaccustomed to sailing in rough seas were given
1 gm of ginger root or placebo every hour for four hours. The
ginger root reduced the tendency toward vomiting and cold sweating.
Thermogenic formulations only produce gastrointestinal distress
in some sensitive individuals, so ginger should definitely be
able to relieve these much milder symptoms. There are no studies
showing that ginger by itself has fat-burning properties.
Citrus bioflavonoids
Numerous studies have indicated that the citrus bioflavonoid naringin
prolongs the chemical activity of caffeine. Research published
in the British Journal of Clinical Pharmacology found
that the half-life of caffeine was extended by 31% when naringin
was present in sufficient amounts. Studies of various citrus fruits
have shown that grapefruit has by far the highest content of naringin.
It is, in fact, what gives grapefruit its characteristic bitter
taste. The activity of other citrus bioflavonoids has not been
studied.
Cayenne and other peppers
The capsaicin in cayenne has been shown to be effective in animal
and human experiments. In a recent 14-day study, rats were given
capsaicin or placebo and put on an exercise program. Compared
to the control rats, the capsaicin group had a greater reduction
in their fat stores. These benefits appear to take place with
both high-carb and high-fat diets. A study of Japanese women on
these two types of diets found that adding cayenne to their food
led to increased energy expenditure and fat oxidation. Both of
these effects would result in a loss of body fat over time. The
extent of the benefits from black pepper and long pepper has not
been clarified by scientific research.
Cinnamon
Cinnamon has been shown in scientific studies to have numerous
benefits related to its antiviral and antibacterial activity.
However, while it is traditionally recommended to treat fatigue,
no study has examined its ability to actually increase thermogenesis
or metabolic rate.
Chromium dinicotinate glycinate
The studies on chromium are all over the board. While it can be
very helpful for diabetics, the demonstrated benefits (or lack
thereof) for nondiabetics depend on the nutritional status of
the participants and the amount and length of the supplementation
program. One study that did show a benefit from the use of chromium
picolinate was presented at the national meeting of the Federation
of American Societies for Experimental Biology in 2000. This study
found a 40% increase in glucose uptake into muscle tissue compared
to the placebo group.
Since insulin can also transport glucose to the fat cells for
storage, these results suggest that chromium helps to shunt the
glucose towards the active working tissues where it can be burned
for energy. The end result could well be a loss in body fat, although
this benefit was not measured. The bottom line is that chromium
is an essential nutrient that is often deficient in most people's
diets. Eliminating this deficiency should at a minimum increase
your adherence to your diet by improving your energy levels and
reducing mood swings.
Methionine
Methionine is an amino acid that must be obtained from the diet,
as the body cannot manufacture it. It assists in fat breakdown
(lipolysis), although it has many other roles in the body. Methionine
is included in fat-burner formulations because of its ability
to support greater levels of fatty-acid oxidation. However, it
has not been studied as a fat burner on its own, so it is not
known how much methionine is needed to promote significant levels
of fat loss.
Siberian ginseng
Siberian ginseng is widely regarded as an effective herb for promoting
the health of the adrenal glands. A study published in Naval
Research Review found that Siberian ginseng has a tonic effect
on the adrenal glands, reducing the production of the catabolic
hormone cortisol. Additional studies have shown that this herb
has an anti-inflammatory effect and that it strengthens the immune
system through its adaptogenic actions.
Other ingredients
Most of the other ingredients in Trim Spa's formulation have –
at best – anecdotal evidence of their effectiveness. Virtually
none of them have been subject to the kind of scientific scrutiny
that is needed to clearly support their use as fat burners. Although
vanadium has been shown to improve insulin sensitivity in diabetics,
its effectiveness in nondiabetics is unproven. Also, while glucosamine
is a valuable nutrient for your joints, its ability to act as
a "thermogenic maximizer" is questionable. Moreover,
since these ingredients are provided in such low dosages, they
cannot significantly contribute to the product's effectiveness.
While Trim
Spa reviews sheds light on the science behind Trim Spa, the only
real way to determine its effectiveness is to actually try the
product out for yourself.
