Fat Reduction Fitness Supplements
The FDA is said to have recently instituted a crack down on weight loss supplements as a result of serious side effects and even death associated with some dietary supplements like ephedra. The ban on ephedra goods resulted to the creation of so-called ephedra free weight loss supplements, these too are said to yield their fair share of issues and they too could be destined to the same fate as ephedra.
These ephedra free medications are said to result in a boost in heartbeat and a few other unwanted effects on healthy individuals according to a health expert who participated in the research project.
The inquiry done with the University of California at Berkeley was the primary one to look into the health effects of reformulated weight loss supplements. Among 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.
Because of the ban slapped on ephedra by FDA, an ever-increasing figure of weight loss product manufactures have turned to extracts of bitter orange. The USB study involved 20 healthy volunteers, who were given sole 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 incorporates bitter orange extracts. The managed drug was shown to effect an increase in cardio pulse rate of up to 16 beats in one minute. The Thermogenic Xenadrine EFX in particular was shown to rev up heartbeat by 13 per cent, something which makes it almost the same in performance to ephedra.
Bitter orange extracts include synephrine, a part present in over 90% of citrus fruits but found in higher concentrations in fruits such as Sour orange, Zhi shi and bitter orange and which is popularly used as a medicine in the control of respiratory tract congestion and high blood pressure. Xenadrine EFX is known for a stimulant in the part, usually caffeine. The amount of caffeine is Xenadrine is estimated to be the equivalent of 3 coffee cups. This is the ingredient responsible for the increase in blood pressure and people using this product are informed against over dosage.
