Need To Know: FAQs

Introduction & Background

What is FBCx?

FBCx is a naturally occurring soluble dietary fiber with a fat binding patent. Unlike any other naturally-occurring fat binding ingredients, it has the ability to bind nine times its own weight of dietary fat and eliminate it from the body.

What is it made from/what does it contain? (What about GMOs?)

FBCx is a soluble fiber derived from grain. One FBCx tablet contains 1 gram of the fiber, α-Cyclodextrin. FBCx contains no genetically modified components.

Who discovered FBCx?

The weight management benefit of FBCx was discovered by two professors from the Department of Nutrition and Food Science and Department of Pathology, of Wayne State University in Detroit, Michigan.

They discovered FBCx in their day jobs as faculty at Wayne State University. A pure research project to satisfy the curious minds of scholars turned out to be much more exciting than they had dreamed. The original research project with an obese animal model identified that one gram of FBCx binds and eliminates 9 grams of dietary fat. It also showed the beneficial effects of FBCx on body weight management, as well as improved glycemic control. These beneficial effects were later verified in clinical trials with overweight healthy adults.

Use and Dosage

How do I use FBCx?

FBCx binds to dietary fat in the stomach. Thus, in order for FBCx to assist you in your weight management, you should take it when you have fat in your stomach. It is recommended that you take 2 grams of FBCx with each of three meals, a total of 6 grams per day. Alternatively, FBCx can be taken with snacks (that contain fat).

When do I take FBCx?

Take FBCx with a fat containing meal or snack.

How much fat is removed from my diet with each dose?

One gram binds and eliminates 9 grams of dietary fat. The recommended dosage of two grams eliminates 18 grams of dietary fat.

How do I determine how much fat is in my meals?

For most of us, the average daily fat intake is about 90-100 grams. Fat is an essential part of a balanced nutritious diet. By taking 2 grams with fat containing meals three times a day, up to 54 grams of fat will be bound and reduced daily.

How long should I take FBCx before I will see results?

Taken as directed, six grams per day is sufficient to decrease your daily caloric absorption by up to 500 calories. 500 calories per day becomes up to 3,500 calories per week, or 15,000 a month. You should begin to see the results in about 2-3 weeks.

Do I have to change my diet?

No, you do not need to change your diet if you are eating a normal, healthy diet. If for you are on a low fat diet, FBCx will not work best for you. FBCx is not a license to overeat, nor is it a magic bullet for quick weight loss.

Does FBCx treat all fats equally? (or does it target certain fats in preference to others?)

Even though FBCx binds and eliminates fat in food, it preferentially binds with and eliminates saturated and trans fats. An animal study conducted by professors at the University of Minnesota demonstrated that FBCx preferentially binds with saturated fat. Another study conducted by scientists at the National Institutes of Health (NIH) showed that animals receiving FBCx had significantly lower levels of saturated and fatty acids in their blood.

What kind of fatty food works most effectively with FBCx?

Since FBCx binds with all fats it works with any fat-containing food. FBCx appears to preferentially bind saturated fats which are most often found in animal products such as red meat and whole-milk dairy products, as well as plant based products such as palm oil and coconut milk.

Will FBCx be useful if I am at a normal weight / BMI index?

Yes. You don’t need to take it with every meal if you have a normal weight. However, when you splurge or enjoy holiday meals and overeating is anticipated, you can take FBCx to reduce absorption of the extra fats you consumed.

What are the health benefits of FBCx, other than weight management?

FBCx helps maintain healthy triglyceride and LDL (bad) cholesterol levels in.

FBCx appears to preferentially bind saturated fats over unsaturated dietary fats.

FBCx may help promote gastrointestinal (GI) regularity.

Safety, Side Effects, Drug Interactions:

Are there any negative reactions?

FBCx is a dietary fiber, albeit with superior fat-binding properties, and like all dietary fibers if you take too much or, in the case of FBCx, if you take it without fat you may get intestinal upset or flatulence. When taken as recommended – 2 grams with fat-containing meals/snacks three times a day, no negative effects are reported.

Will I get diarrhea or some other negative digestive effect – or other negative side effects?

No, unlike other weight loss products FBCx binds the fat from food so that it will not be digested by the enzymes in your small intestine. Similarly, the FBCx-fat complex that passes into the large bowel cannot be fermented by your natural intestinal bacteria. The fermentation process requires free unbound fat and causes the flatulence, explosive diarrhea and anal leakage that are the common side effects of some pharmaceutical products.

No messy side effects have been observed in clinical studies.

Will there be a period of adjustment to tolerating FBCx? 

For those individuals whose typical diet is low in dietary fiber, it may take a few days to adjust to the increase in dietary fiber; whether from FBCx or any source of dietary fiber. This tolerance adjustment may be manifested by constipation, bloating and flatulence.

What happens if FBCx is taken with a fat-free meal?

If a meal contains no fat, then there is no need to take FBCx. Otherwise there may be intestinal upset or flatulence.

Is FBCx safe?

The FDA have designated the GRAS (Generally Recognized As Safe) status to FBCx α-cyclodextrin.

How long can I take FBCx?

You can take FBCx as long as you like. FBCx, as a fiber, is not absorbed into our body hence there is no concern about developing a tolerance. Once you have reached your ideal weight you may wish to lower your intake or just take it during dietary indiscretions, like holiday meals.

How long does FBCx remain in your system?

FBCx binds with dietary fat and is eliminated bowel movements. FBCx is not metabolized, it binds to dietary fat and passes through the system and into the feces.

Does FBCx just work in your digestive tract and get excreted (along with the fat it has bound to) or does some get digested? 

FBCx will be eliminated together with bound fat. It is a dietary fiber and will not be absorbed by the small intestine. Therefore FBCx will never enter the bloodstream. Like other dietary fibers, if when it enters the large bowel it is not bound to fat, a small portion of it may be fermented into small naturally occurring fatty acids that may be absorbed.

Are there health warnings?

FBCx doesn’t have any health warnings. Instructions to “Keep out of the reach of children” serves as a precaution.

Has FBCx been approved by the FDA?

FBCx is a food supplement and is allowed by the FDA. The FDA “approves” pharmaceuticals and “allows” dietary supplements.

What happens if I forget to take FBCx with one of my meals?

We recommend that you save it for the your next fat containing meal or snack.

Is FBCx safe to take with prescription drugs?

We are not aware of any reports of adverse events from taking FBCx with prescription drugs. If you have concerns you should talk to your health professional.

Can I take FBCx when I am pregnant or nursing?

We do not recommend pregnant or nursing women take FBCx.

Should I avoid a high fiber diet while taking FBCx?

All other fibers are not efficacious in binding and eliminating dietary fat. Therefore, there is no need to avoid a high fiber diet.

Does the FBCx fiber count as part of my daily fiber intake?

Yes, FBCx can be counted as part of the daily fiber intake. Most of us consume only about half of the recommended daily fiber intake.

Are there more studies underway?

SFI is committed to ongoing clinical trials for FBCx.
