Skinny Fiber – as you can probably get from its name – is all about using fiber to support the weight loss process. Because Skinny Fiber is one of the most popular weight loss supplements available on the market, we decided to give it a 360-degree review, examining ingredients, side effects, clinical research and customer-service quality.

As stated above, Skinny Fiber is a diet pill. It’s formula features glucomannan, a water-soluble fiber that is claimed to expand in the stomach to help you feel fuller and eat less.

While the overall formula looks interesting, we are somehow concerned about the company behind Skinny Fiber. A quick online research revealed that the manufacturer’s headquarters is located în the middle of a shopping center. It is hard to imagine someone researching, developing and testing formulas in a facility in the middle of a shopping center.


Skinny Fiber contains the following ingredients: Skinny Fiber contains the following ingredients: Proprietary blend (Glucomannan powder, Caralluma fimbriata, Cha de Bugre powder), Proprietary Enzyme Blend (Amylase powder, Protease powder, Lipase powder, Glucoamylase powder, Papain powder, Cellulase powder, Bromelain powder), gelatin capsule, microcrystalline cellulose, and magnesium stearate.

Product Features

We have to start our review by saying that Skinny Fiber’s formula is not unique, it consists of ingredients that are commonly used in other weight loss supplements too.

Glucomannan is a water-soluble fiber. This fiber has the property to absorb water and expand. However, in order to do that it needs to be enough water in the stomach for the fiber to absorb for it to expand 20, 30 or 40 times.

The second key ingredient, Caralluma Fimbriata is a cactus extract that reduces appetite. But this sounds a lot like the Hoodia cactus, right? According to the company, Caralluma Fimbriata will reduce hunger and inhibit the formation of fat, but none of these claims are supported by relevant clinical research.

The final key ingredient is another plant extract – Cha de Bugre, a Brazilian plant that contains caffeine. However, the caffeine levels are much lower in this plant than in other stimulant herbs, but even so the stimulating effect may last longer than with standard caffeine.

  • Skinny Fiber contains Glucomannan, a water-soluble fiber, which can expand up to 50 times in the stomach and reduce the sensation of hunger;
  • A full list of ingredients is available on the official website.


  • Unimpressive formula that lacks proven weight loss ingredients;
  • At $39.90 a bottle, Skinny Fiber is more expensive than other similar weight loss supplements;
  • The official website lacks relevant information. Most of their research links to a “Coming Soon!” page.


We have some concerns regarding the information provided by the manufacturer. For instance, the official website has a button for dieters to learn more about how Skinny Fiber is supposed to work, but the button links to a “Coming Soon!” page.

The price is another concern. According to the company, Skinny Fiber contains a good source of fiber but that fiber is widely available for around $5 in many stores, while a bottle of Skinny Fiber is just under $40.

BrainReference.com is always interested in looking deeper into weight loss pills like Skinny Fiber, and we appreciate the fact that the company provides a weight loss pill that can help you feel fuller, longer.
