The first thing you should remember is this: authentic hoodia supplements rarely cause any side effects. But just like any other popular commodity, cheap replicas come out claiming to be as good as the real thing. These contain additional ingredients such as stimulants that cause negative side effects on a person. The most usual symptoms include a constant feeling of nervousness or being overexcited. If you experience those mentioned above, it could mean that what you bought were counterfeit hoodia supplements. Natural herbal supplements became popular in the market sometime in 2004. We must take note that although African natives have long been using hoodia with no side effect whatsoever, their consumption of the plant was not as often compared to let’s say, a young woman who intakes it everyday as a diet supplement. Comprehensive studies have to be done in order to completely authenticate the safety of any herbal product especially if they are not authentic. In order to save yourself from any unwanted side effects brought about by fake hoodia, make sure that you’re buying the real thing. Always read the product labels carefully. Look for "hoodia gordonii" that has little to no additives if possible. As mentioned earlier, some additional ingredients may cause side effects that you would rather not face. Watch out for caffeine and other stimulants as these may cause unexplained nervousness or overexcitement. Try to look for supplements that contain 100% pure hoodia gordonii extract in order to gain maximized effectivity with less risks. You can also do a background check on the manufacturers of the product and try to see if they are duly accredited by the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES). The hoodia gordonii plant is actually a well-protected plant that entails tight restrictions on its manufacturing and exportation. Browse on the company’s website and look for a CITES certification. Examine the products out there. Make sure that you are buying an authentic hoodia supplement. It may bother you for a few minutes but it could spare you from the negative effects of buying an adulterated fake.
