July 14, 2005
A study conducted by University of California-San Francisco
has published that weight
loss supplements containing ephedra and guarana
changes the cardiovascular system by increasing heart
beat rate and blood pressure. It also has negative influence
on glucose and potassium homeostasis.
The study spearheaded by Dr. Christine A. Haller and
colleagues from the above university took the experimental
group of 16 healthy adults. Two tests were performed
with this set of people. Supplements taken were Xenadrine
RFA and the other a combination of two supplements.
Xenadrine RFA contained 25.4 mg ephedra alkaloids and
85 mg caffeine. The other contained 23.2 mg ephedra
alkaloids and guarana containing 167 mg caffeine.
The results revealed that repeated intakes of supplements
had bad effects on the cardiovascular system. The results
published in the June, 2005 issue of Clinical Pharmacology
and Therapeutics said that weight loss supplements containing
ephedra and guarana may change cardiovascular and metabolic
conditions. These in turn prove harmful to obese people
with already have high blood pressure, clogged arteries,
or glucose intolerance. Therefore ephedra and guarana
could worsen obesity-related conditions such as insulin
resistance and metabolic syndrome, according to the
study.
