Fat Loss Nutritional Supplements

 

The FDA is said to have just lately instituted a crack down on weight loss supplements as a result of very bad negative effects and even death associated with some dietary supplements like ephedra. The ban on ephedra products resulted to the creation of so-called ephedra free weight loss supplements, these too are said to yield their own fair share of conditions and they too might be most likely going to exactly the same fate as ephedra.

These ephedra free medications are said to cause a boost in heartbeat and a couple other unintended effects on healthy folks reported by a health authority who participated in the research project.

The study done with the University of California at Berkeley was the first one to go into the health effects of reformulated weight loss supplements. One of the things analyzed for included high blood pressure and heart beat rate of volunteers who were given reformulated weight loss supplements made from extracts of bitter orange.

Because of the ban slapped on ephedra by FDA, an ever-increasing number of unwanted weight loss product manufactures have switched to extracts of bitter orange. The USB research engaged 20 healthy volunteers, who were given sole doses of a weight loss supplement or a placebo.

The diet supplements examined in the research program were Xenadrine EFX and Advantra Z, each of which possesses bitter orange extracts. The administered drug was shown to produce a rise in heart pulse rate as high as 16 beats in one minute. The Thermogenic Xenadrine EFX in particular was shown to rev up heartbeat by 13 per cent, something that makes it almost the same in performance to ephedra.

Bitter orange extracts include synephrine, a component specific to over 90% of citrus fruits but found in greater concentrations in fruits such as Sour orange, Zhi shi and bitter orange and which happens to be commonly used as a medicine in the control of respiratory tract congestion and blood pressure. Xenadrine EFX is known for a stimulant in the part, usually caffeine. The quantity of caffeine is Xenadrine is thought to be the same as 3 coffee cups. This is the component the cause the increase in blood pressure and people using this product are cautioned against over dosage.
