The ingredients in the Xentrafen proprietary formulation include: 1,3,7 Trimethylxanthine (caffeine anhydrous), Synephrine HCl, N,N-Dimethyltyramine, Schizandrol A, 5-Hydroxytryptophan, Yohimbine HCl. Additional ingredients listed are: Magnesium Stearate and Silicon Dioxide. No specific information was provided on the manufacturer’s website about these ingredients and no studies were mentioned or cited to backup claims that were made about the efficacy and benefits of this diet pill product.
At the time this review was written, a bottle of Xentrafen contained 60 capsules (a 30-day supply), sold on the manufacturer’s website for $44.99, and came with a 100% money-back guarantee. Users are directed to take two capsules, daily (1 capsule before lunch and 1 before dinner). It is also noted that “advanced users” can take a third capsule if additional appetite suppression is needed.
It is surprising that it is recommended to users to take a capsule before dinner and that even a third capsule is recommended for advanced users. The reason being is this product contains caffeine and other stimulants, which means that it increases the risk of unpleasant side effects that can effect and disrupt sleep, among other adverse effects.
In addition, another red flag about this product is that it contains synephrine. Although this was once considered an ideal replacement for Ephedra, after it was banned, this is no longer the case. The FDA has released a warning, cautioning consumers not to use products that contain this ingredient – which is also commonly known as bitter orange and citrus aurantium – for the purpose of losing weight. The issue is that synephrine can lead to dangerous and powerful side effects, especially when combined with other stimulants such as caffeine, which is one of the ingredients in Xentrafen. The possible adverse effects include, but are not necessarily limited to, an increased risk of stroke and heart attack.
Therefore, if you do decide to consider Xentrafen, do so with caution. Even though it is available without prescription, it may not be a safe product for you to take. For this reason, it is in your best interest to consult with your doctor.
