In a recent 22 week
study, funded by Applied Food Services, Inc. subjects lost an average of 22 lbs.
and no adverse side effects were found. Green coffee bean extract has been
associated with weight loss and with all weight loss products there is always
good reason to be cautious.
In theory, the caffeine
content of green coffee bean extract could
potentially cause problems for some people. However, since green coffee bean extract
contains only about 10% caffeine by weight, a high daily dose contains no more
than about 20% of the caffeine content of
a strong cup of coffee.
Animal studies have found evidence
that chlorogenic acids from green coffee bean extract can reduce blood
pressure. Based on this, researchers have started conducting human trials.
Right now there are not enough
studies to prove that green coffee bean extract lowers blood pressure but the
researchers are very excited about results. Chlorogenics Acids and green coffee
bean extract have been found to lower blood pressure in over stimulated rats
and humans in a controlled study. No adverse results were found.
Roasted (as opposed to
green) coffee beans contain the substances kahweol and cafestol, which appear
to increase levels of LDL ("bad" cholesterol). The fact that green
coffee bean extract does not contain these substances is used as an argument in
its favor. However, these substances remain in the coffee grounds and so they
are also not present in standard beverage coffee, so this is probably not a
significant point. Unfiltered or boiled coffee, with the grounds left in,
however, may present a risk.
Of course green coffee bean extract
has also shown a bit of promise for aiding weight loss, perhaps in part due to
its chlorogenic acid content. The caffeine in green coffee bean extract proves
to be a weight loss benefit.
In studies green coffee bean extract
is thought to be a safe substance. In human trials, no significant adverse
effects have yet to been seen.
In the large human trial of green
coffee bean extract for hypertension noted above, the extract was most
effective when taken at a dose of 185 mg daily.
Since green coffee bean extract
typically contains about 30% chlorogenic acids, this works out to a dose of
about 60 mg of chlorogenic acids daily. Another study used 140 mg of purified
chlorogenic acids daily. This is important in weight loss and in reducing blood
pressure.
In theory, the caffeine content of green
coffee bean extract could potentially cause problems for some people. However,
since it contains only about 10% caffeine by weight, a high daily dose contains
no more than about 20% of the caffeine content of a strong cup of coffee.
Maximum safe doses in pregnant or
nursing women, young children, or people with liver or kidney disease have not
been established.
Stay healthy,
live positive!!
