Excess Weight Reducing Supplements

 


The FDA is said to have as of late instituted a crack down on weight loss supplements as a result of serious negative effects and even death associated with some dietary supplements such as ephedra. The ban on ephedra products resulted to the roll-out of so-called ephedra free weight loss supplements, these too have been shown to yield their fair share of situations and they too could be meant to the same fate as ephedra.

These ephedra free supplements are said to trigger an increase in heartbeat and a some other unwanted effects on healthy people as outlined by a health authority who took part in the research.

The inquiry done through the University of California at Berkeley was the initial one to research the health effects of reformulated weight loss supplements. Among the things screened for included blood pressure and pulse rate of volunteers who were given reformulated weight loss supplements produced from extracts of bitter orange.

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

The diet supplements used in the research program were Xenadrine EFX and Advantra Z, each of which includes bitter orange extracts. The administered drug was shown to produce a slight increase in cardiovascular pulse rate as high as 16 beats in one minute. The Thermogenic Xenadrine EFX especially was shown to rev up heart rate by 13 per cent, a thing that makes it almost equivalent in performance to ephedra.

Bitter orange extracts possess synephrine, a element present in over 90% of citrus fruits but found in increased concentrations in fruits such as Sour orange, Zhi shi and bitter orange and which is widely used as a medicine in the management of respiratory tract congestion and blood pressure. Xenadrine EFX is known for a stimulant in the constituent, usually caffeine. The amount of caffeine is Xenadrine is estimated to be the equivalent of 3 coffee cups. This is the ingredient to blame for the surge in blood pressure and patients using this product are informed against over dosage.
