What is FBCx?

The fiber alpha-cyclodextrin is derived from corn and is marketed under the name FBCx. It is a soluable fiber which is claimed to bind with and eliminate up to nine times its own weight in dietary fat. FBCx is marketed in the U.S. under the brand name Calorease.

FBCx.com was registered in November 2005, while Calorease.com was registered in July 2011. Below is a screen shot of fbcx.com, captured in February 2014.


How much does FBCx cost?

A 90-count (15-day supply) of Calorease direct from the official website costs about $30. A 180-count (30-day supply) costs $49.99. Shipping is $5.99.

At GNC, they use the same pricing as calorease.com, but offer member discounts. The 180-count at GNC, for example, costs members $34.99. (Note that Calorease disappeared from GNC’s website, which is possibly due to high demand. We’ll keep an eye on this to determine if that is temporary or permanent.)

Other FBCx/Calorease Reviews

Calorease is available online at GNC, and as of this writing the reviews are mixed, with comments ranging from “waste of money” to “it’s working.” It has a 3.5 star rating with only a small handful of reviews. After the Dr. Oz show aired, Calorease went out of stock in some locations and online.

Dr. Oz

FBCx was featured in a segment of Dr. Oz in February 2014. He referred to it as a “fat-eating fiber.” He did not mention Calorease, and the display used in the episode was a generic-looking bottle that may have been used for demonstration purposes only. “This is a very cool fiber which as amazed my entire staff,” Dr. Oz said. “It can eliminate nine times its weight… It’s gonna do it over time, but it will do it.”

FBCx Research

There have been a few studies published regarding FBCx, incluidng:

  • The benefits of early intervention in obese diabetic patients with FBCx: a new dietary fibre (Grunberger G, Jen KL, Artiss JD., 2007). This study concluded, “FBCx has thus shown promising benefits in weight maintenance, a reduction of blood lipids and an increase in adiponectin levels. It can be easily incorporated into a diabetic management regimen.”
  • The beneficial effects of ?-cyclodextrin on blood lipids and weight loss in healthy humans (Comerford KB, Artiss JD, Jen KL, Karakas SE, 2011). This study found that FBCx works in non-obese people as well, concluding, “These results suggest that a-CD exerts its beneficial health effects on body weight and blood lipid profile in healthy nonobese individuals, as previously reported in obese individuals with type 2 diabetes.”
  • Earlier studies on rats saw promise with the new fiber, such as this study which concluded, “It would appear that FBCx might be effective in reducing body weight gain and improving metabolic syndrome.”

Side Effects of FBCx

The most prominent side effect is gas if is not taken with a meal. As the Calorease FAQ states, “If you take too much or don’t take it with a meal or snack containing fat, you may experience intestinal upset or flatulence.”

  1. if you are on a diet and you mess up and consume a greasy meal then you should take the pill.. that was the only instruction

  2. If I understand it correctly FBCx binds fat that’s eaten with your meal. My question is if a person’s meal contain little fat will it bind fat that is already stored in the person’s body? Will the person still see results and at the same rate?
