Weight Loss: Another Role for L-
Carnitine
I’ve always felt that L-carnitine is deserving
of more attention than it gets. Carnitine is a
substance that plays an important role in
energy production. That alone should get
your interest. Even better, it does this by
enhancing, or facilitating, the transport of
fatty acids across the cell membrane, from
the blood stream into the cellular mitochon-
dria, where it is used as “fuel” for energy
production. So, not only does it clear fats
(fatty acids), but it also boosts energy. In
addition, it has been shown to exert antioxi-
dant activity, enhance immune function and
support the body’s detox functions.
We have written about carnitine many
times in the past, and have discussed it on
The Willner Window radio show. You can
read these informative articles and tran-
scripts, and listen to audio files if you wish,
on the Willner Chemists web site. Go to
www.willner.com. Click on “Advanced
Search” in the “Library Quick Search” box on
the left side of the home page. Select “carni-
tine” from the drop-down keyword menu.
Why am I bringing it up again? I’ve always
felt that L-carnitine should be of value in
weight loss. A new, small study was released
recently that supports this idea. In the study,
they worked with 24 overweight Japanese
men. It was a double-blind randomized
placebo-controlled study.
The 24 overweight adult men were split
into 4 groups: Group A received 500mg L-
carnitine; group B received the same with
motivation training; group C received place-
bo and group D placebo plus motivation
training.
“Motivation training included a face-to-face
30 minute session with the principal investi-
gator at the baseline visit, where the subjects
were informed about L-carnitine and its
metabolic functions,” the researchers wrote.
“Furthermore, subjects learned about the
beneficial effect of weight loss on the risk of
metabolic diseases. Subjects were encour-
aged to perform daily physical activities like
‘taking stairs’ instead of ‘using escalators’.”
They were also instructed to try to reduce
calorie intake to 1500-1800 kcal by taking
lighter meals.
Surprisingly, that small 500 mg dose of L-
carnitine seemed to make a difference. Only
group B–the group receiving carnitine and
motivational training--showed a statistically
significant weight reduction of 1.1kg com-
pared to an increase of 0.7kg in the placebo
non-motivated group.
Now this was a small study, and certainly
should considered limited in value. But it’s
one of those situations where we are dealing
with a substance, a supplement in this case,
that has many beneficial actions. In this case,
the researches also measured a decrease in
triglyceride levels, for example. Even though
it was a small study, and only for four weeks,
the researchers point out that the results
were significant.
“This may be a crucial limitation that weak-
ens the significance of the results, although ...
Low dosage L-carnitine combined with moti-
vation may have a beneficial effect on several
metabolic syndrome risk parameters, includ-
ing triglycerides and adiponectin, which
could offer a safe, low cost, and easily appli-
cable strategy targeting weight loss in over-
weight humans."
