Lipo 6 Black Ultra Concentrate is a nonprescription weight loss supplement from an American manufacturer called Nutrex. This product is marketed not only as a fat burner, but something that goes above and beyond that level. It goes to the extent of saying that there is “Extreme Caution Advised” in the product description on its own official site. The reason is that they claim that this is the strongest of their Lipo 6 products.
What this implies is that this product is targeted at people whose primary concern is to be able to lose weight quickly, even if that means that they will be taking a few risks with their health along the way.
The reason that Lipo 6 Black Ultra Concentrate comes with a warning is that it is very high in stimulants, which will increase energy, metabolic, and adrenaline levels. While this could mean that you will burn fat more quickly and your appetite may shrink, it may also mean that many dieters will experience uncomfortable unwanted side effects such as shakes and jitters, nausea, headache, increased heart rate, heart palpitations, anxiety, nervousness, restlessness, gas, diarrhea, and other discomforts. For people who have certain common health conditions, this product could actually be dangerous.
At the time of the writing of this review, the ingredients listed on the package for Lipo 6 Black Ultra Concentrate were: caffeine anhydrous, theobromine anhydrous, Advantra Z (citrus aurantium), yohimbine, and rauwolscine. All of these ingredients are stimulants and it is important to point out that there are two types of stimulant in this product that are known to produce dangerous effects in some people. The combination of caffeine anhydrous and synephrine (the Advantra Z is 50 percent synephrine) is dangerous enough that the FDA has released a warning against using these substances together. The reason is that it places dieters at an increased risk of certain very serious cardiac events such as heart attack and stroke.
When there is such a large range of different weight loss products on the market today, it is very difficult to be able to come up with a single reason to recommend this product. It is highly recommended that a doctor be consulted before using this product as it could help to reduce the chances that you will use this product if you have any of a number of common health conditions that could cause the stimulants in this product to become hazardous to you.
