The FDA is said to have as of late instituted a crack down on weight loss supplements as a result of very bad adverse reactions and even death associated with some dietary supplements such as ephedra. The ban on ephedra merchandise resulted to the roll-out of so-called ephedra free weight loss supplements, these too are said to yield their own fair share of problems and they too might be meant to the same fate as ephedra.

These ephedra free drugs have been shown to trigger a rise in heartbeat and a couple other unintended effects on healthy people as outlined by a health expert who participated in the research project.

The inquiry carried out by the University of California at Berkeley was the initial one to research the health effects of reformulated weight loss supplements. One of the things tested for included blood pressure and heart beat rate of volunteers who were given reformulated weight loss supplements made out of extracts of bitter orange.

After the ban slapped on ephedra by FDA, a growing sum of body fat loss product manufactures have changed to extracts of bitter orange. The USB examination included 20 healthy volunteers, who received single doses of a weight loss supplement or a placebo.

The diet supplements tried in the research program were Xenadrine EFX and Advantra Z, each of which possesses bitter orange extracts. The applied drug was shown to cause an increase in heart pulse rate all the way to 16 beats in one minute. The Thermogenic Xenadrine EFX for example was shown to rev up heartbeat by 13 per cent, a thing that makes it almost similar in performance to ephedra.

Bitter orange extracts possess synephrine, a element specific to over 90% of citrus fruits but found in increased concentrations in fruits such as Sour orange, Zhi shi and bitter orange and which happens to be popularly used as a medication in the management of respiratory tract congestion and high blood pressure. Xenadrine EFX includes a stimulant in the part, usually caffeine. The amount of caffeine is Xenadrine is approximated to be very similar to 3 coffee cups. This is the element to blame for the rise in blood pressure and people using this product are informed against over dosage.
