Product Features

One XS is a dietary supplement claiming to suppress appetite, increase metabolism and assist dieters lose weight fast. The website states dieters will lose a minimum of 15 pounds in the first month. There was no information relating to clinical trials or scientific research. The only information available relating to the efficacy of One XS was online testimonials. Even the testimonials were a mixed bag. Several claimed the product did not provide energy or suppress appetite.

The cost of the product is rather expensive compared to similar products. One bottle retails for $40 on the website. Even third-party supplement sites sell the product for the same price.

We did notice the inclusion of green tea. This is the only proven weight loss ingredient. The unfortunate side of including a proven ingredient is the dieter does not know the exact amount contained in One XS. The ingredients are listed in a proprietary blend.

Between the misinformation on the official website and the misleading testimonials online, we are up in the air regarding One XS. The claims on the website tell the dieter they will lose a minimum of 15 pounds in one month. The company goes further and states dieters could lose more. The company also makes claims of appetite suppression as well as increased metabolism. There are several red flags relating to One XS. There is not information relating to clinical trials associated with anyone taking the supplement. There is no information relating to scientific research.

The ingredients listed on the site include clinically proven ingredients, but the amount of the ingredients is not available. In addition, there is no verifiable research proving the efficacy of Garcinia Gambogia as an appetite suppressant. There are several concerns noted as to why dieters should avoid One XS. A balanced diet combining the correct amount of supplements and exercise will result in weight loss, not a “magic” diet pill.
