Skinny Fiber Review 2019 – Benefits & Side Effects

Skinny FiberWhat is Skinny Fiber

Skinny Fiber – as the name suggests – is all about using fiber to help the weight loss process. Because Skinny Fiber is one of the most appreciated weight loss supplements available at this moment, we decided to give it an in-depth review, with a closer look at ingredients, available clinical research, ingredients, and of course customer service quality.

Skinny Fiber weight loss supplement is produced by a US company called SkinnyBodyCare (SBC), located in Murray, Utah. They have an official website that is packed with information and user testimonials with dozens of “before and after” photos. However, the company operates as a multi-level marketing company, which is concerning, especially because of their very low rating on the Better Business Bureau.

Skinny Fiber Ingredients

Skinny Fiber includes the following ingredients: Proprietary blend (Glucomannan Powder, Caralluma Fimbriata Whole Plant, and Cha de Bugre Leaf Powder) 1100 mg and Proprietary Enzyme Blend (Amylase Powder, Protease Powder, Lipase Powder, Glucoamylase Powder, Papain Powder, Cellulase Powder, and Bromelain Powder) 180 mg.

Other ingredients include: Gelatin capsule, microcrystalline cellulose, and magnesium stearate.

Benefits of Skinny Fiber

According to SkinnyBodyCare, Skinny Fiber is an appetite suppressant and a powerful weight loss enablers that can also support proper metabolic functions.

To start with, this formula is not unique. It includes ingredients that are commonly used in other weight loss supplements too. One of the core ingredients, Glucomannan, is a water-soluble fiber that can absorb water and expand. But in order to do that, it needs enough water in the stomach for the Glucomannan to absorb and grow 10, 20, 30, or 40 times. This is one of the reasons the company recommends you drink a lot of water when taking Skinny Fiber.

The second core ingredient, Caralluma Fimbriata is a cactus extract that has been shown to reduce appetite. But that’s no different from the Hoodia cactus, which has far more medical benefits and it’s a far more traditional ingredient. Furthermore, our research team could not find any relevant clinical studies that can prove the benefits of Caralluma Fimbriata. While the company claims that this ingredient was added to reduce hunger and inhibit the formation of fat, there is no clinical evidence to support this statement.

Cha de Bugre Extract is the third core ingredient. Cha de Bugre is a Brazilian plant that has been used for centuries by the Traditional Medicine. It contains small amounts of high-quality caffeine, which is responsible for the stimulating effects of this plant.

The Proprietary Enzyme Blend seems a bit off. The blend contains seven different ingredients for a total amount of 180 mg. This means that, on average, the Proprietary Enzyme Blend contains about 25 mg of each ingredient – a tiny amount that is unlikely to provide any real benefits.

So why does this Proprietary Enzyme Blend even exists? These ingredients might act as enablers for the core compounds in Skinny Fiber, allowing them to act faster and better and provide more noticeable results. But we can only speculate without any clinical study to confirm this theory, which is never a good thing when it comes to weight loss supplements.

How Much Does Skinny Fiber Cost?

Skinny Fiber is quite expensive at $59.95 for a single bottle (120 capsules). The official website recommends two capsules before each meal. If taking the supplement before two meals per day (four capsules each day), a single Skinny Fiber bottle would last for up to 30 days. However, if taken before three meals per day (six capsules each day), a single bottle would last for just 20 days. So you would end up paying up to $100/month.

Potential Skinny Fiber Side Effects

Some consumers have complained about the many unpleasant and even serious side effects associated with the use of this supplement. Based on the testimonials we have found online, these side effects include increased bowel movements, diarrhea, vomiting, bloating, stomach cramps, trapped gas, constipation, acid reflux, and nausea.


  • Glucomannan, one of the core ingredients in Skinny Fiber, is a water-soluble fiber, which can expand up to 50 times in the stomach, reducing the sensation of hunger
  • All ingredients are listed on the official website
  • Many testimonials claiming the supplement works


  • Quite expensive compared to other weight loss supplements; you might end up paying up to $100/month
  • The Proprietary Enzyme Blend seems to serve no purpose in the overall formulation
  • Lacks proven weight loss ingredients

Final Verdict

The lack of proven ingredients and the high price/month many consumers will end up paying are the two reasons we can’t recommend Skinny Fiber. The company claims their product is a good source of fiber, but the fiber is widely available for $4-5 in many online and offline stores, while a single bottle of Skinny Fiber (120 capsules) costs $59.95.
