Product Information


BarnDad’s FiberDX™

    44% of daily requirement*

BarnDad’s FiberDX™ is a 100% natural, time-release, soluble and insoluble fiber matrix that naturally reduces hunger and supports healthy weight management, lean muscle and a healthy digestive system. Originally developed in Germany, where it was used to successfully treat diabetic and obese patients, BarnDad’s FiberDX™ reduces hunger and slows the digestion and absorption of sugars and carbohydrates. This helps reduce insulin spikes and allows glucose to be metabolized more effectively.

BarnDad’s FiberDX™ also supports heart health. It’s long been clinically proven that a diet high in fiber helps reduce cholesterol and triglycerides, which has a positive impact on the body’s mechanisms for regulating healthy cholesterol production. Health experts recommend a healthy diet include a minimum of 25 grams or more of fiber per day. One serving of BarnDad’s FiberDX™ provides 11 grams of Fiber, a full 44 PERCENT of your daily fiber requirement.

While many single fiber products or supplements (imbalanced blends) often cause bloating, BarnDad’s FiberDX™ patent-pending, eight-layer fiber matrix works in days to provide consumers all the benefits of a high fiber diet without the negative side effects.

BarnDad’s FiberDX™ is a flavorless, universal ingredient that easily mixes with water or other beverages and can also be used in baking as a flour substitute, resulting in healthy and delicious meals, snacks and desserts. BarnDad’s FiberDX™ is the ultimate fiber supplement for optimum health, peak performance and vitality at any age.

Perfect to start the day with a ton of your daily fiber already taken care of. I have used many different fiber supplements...this one is a keeper! My wife and I add Fiber DX to our Vega One in the morning for a power packed breakfast that keeps us full! Mixes easily with protein shakes or is ok with water too. Smooth texture. Get your blender bottle and go!

Best fiber supplement out there
I've been using Barn Dad's Fiber DX supplement for a couple of weeks and I'm impressed. Goes great with most drinks as it mixes well. I enjoy it most with vanilla almond milk. 11g of fiber which is near 50% of my recommended dose and also has 7g of protein as an added incentive. Definitely worth the price!!

A 15% price increase, seriously?
While I think the product is good - GNC is the one that gets "one star" for recently imposing a ridiculous price increase on this product. In 11/2015, I paid $27.99 per unit as a "GNC Member". It's since gone up by 15%! Even with the "member discount", I can get it cheaper elsewhere. I won't be renewing my GNC membership, that's for certain.

Fiber DX is great.
Fiber is one of the most overlooked nutrients, Fiber DX is an effective way to get the fiber we need to keep us healthy. I recommend mixing this in with your protein shakes once or twice a day!

Best way to get your fiber!
I felt compelled to mention my good experience since this product became available. Nothing I've ever found provides the level of fiber without gassiness and improved level of elimination. Your system will be quite regular with the benefit of a much flatter stomach. Simply adding this product to my regular diet has benefitted me with a lower LDL profile over the last year (2 separate tests)

Great daily fiber addition!!
I use this daily in my protein shakes. I like the fact that it gives the shakes substance and fulfills my daily fiber requirement. Would definitely recommend to anyone on a disciplined workout routine.

Wonderful source for fiber!
I am very happy with the taste of the product. It was an excellent source of fiber without the uncomfortable bloating that is common with other fiber supplements. I highly recommend this product for my clients.
