Excess Weight Slimming Down Supplements

The FDA is said to have as of late instituted a crack down on weight loss supplements as a result of serious uncomfortable side effects and even death connected with some dietary supplements such as ephedra. The ban on ephedra goods resulted to the introduction of so-called ephedra free weight loss supplements, these too have been shown to yield their fair share of situations and they too could possibly be destined to the same fate as ephedra.

These ephedra free medications are said to result in an increase in heart rate and a several other unintended effects on healthy people based on a health expert who was in the study.

The study performed through the University of California at Berkeley was the best one to go into the health effects of reformulated weight loss supplements. Some of the things investigated for included high blood pressure and heartbeat rate of volunteers who were given reformulated weight loss supplements created from extracts of bitter orange.

Since the ban slapped on ephedra by FDA, a large amount of body weight loss product manufactures have turned to extracts of bitter orange. The USB research required 20 healthy volunteers, who received sole doses of a weight loss supplement or a placebo.

The diet supplements tried in the study were Xenadrine EFX and Advantra Z, each of which consists of bitter orange extracts. The administered drug was shown to influence 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, something which makes it almost similar in performance to ephedra.

Bitter orange extracts contain synephrine, a part specific to over 90% of citrus fruits but found in larger concentrations in fruits such as Sour orange, Zhi shi and bitter orange and which can be popularly used as a relief medication in the therapy of respiratory tract congestion and blood pressure. Xenadrine EFX includes a stimulant in the component, usually caffeine. The quantity of caffeine is Xenadrine is thought to be the same as 3 coffee cups. This is the element responsible for the boost in blood pressure and patients using this product are cautioned against over dosage.
