I use a fiber supplement daily to address a condition which causes longer transit times for me during the digestive process, which could lead to serious and even dangerous constipation and even "impaction." My gastroenterologist said that I could either take medication for rest of my life or take Benefiber (his exact words). Because of the immediate relief I got from bloating and sharp, piercing pains in my back and sides, I felt that benefiber must be a miracle treatment, so despite the price tag, I gladly ran to Sam's every couple of months and spent the $23 or so per 190 dose container (26.8oz). The problem was, and later became all about availability, so I was always concerned about not being able to get it. I said all that to say that I was basically forced to try Optifiber. As a long-time user of "generics," even back when all types first came out in white (later yellow and black) bottles, cans, and bags with black writing in the late 70's or early 80's, I realized that if the active or main ingredients were the same (with few exceptions), the "thing," whatever it might be, was likely no different than the original. Also, while frugal, I make sure never to buy imitations or knock-offs, because they are always more expensive in the end. That brings me to the this point: optifiber is not a knock-off, but the genuine article (wheat dextrin). The only difference from benefiber, is that O-fiber is less refined and has a bit of a yellowish tint; none of which affects the quality or effectiveness of the product. As relates to it being more coarse, I tend to like that, as one of the few problems I had with benefiber, is that it was too powdery and tended to leave residue on my countertop; plus, it was so light that I always thought I needed heaping teaspoons of it, because it never seemed quite enough would make it into the glass. Also, with benefiber, I would still get episodic stabbing pains from time to time. With Optifiber, I made it through my first 190 dose container (of 3 total at an extremely reasonable price) with zero episodes of pain. Lastly, though the coarser powder dissolves more slowly in water, I did not experience any clumping, gumminess, or any other of the undesirable effects I'd read about when I researched the product for purchase in February (2022). I tend to allow the powder to sit in water for a minute, before stirring it for about 60 seconds. With Benefiber, I didn't wait the minute before stirring, but that's trivial for me. Lastly, since I take my first dose of Optifiber in my morning coffee, and my second in my oatmeal, I'm not inconvenienced in the least. I recommend this product to anyone tried of hunting down Benefiber, only to pay twice the price for something that may be only as effective as Optifiber, and possibly even less! Read more

The fact that this is flavorless and non thickening makes it ideal to help keep my aging father in law regular. We can stir it into oatmeal or coffee (warm beverages and foods are easier because it dissolves better). Highly recommended and this is an excellent price! Read more

I don't notice any taste. I'm doing the ketosis diet which is extremely light on fiber so any night's I "cheat" a little bit and have more carbs than I should I chug down 8 servings of this in a big Nalgene bottle of water. I use this every few days during my intermittent fasting routine so that whenever I do... go... the river runs smooth so to speak. Only downside is that it takes a bit of fishing to find the scoop. I like the little spot you can prop it up on the lid. Also worth keeping the scoop for other stuff that needs 1-2 teaspoon servings! Read more

Before using this product I had an awful problem with IBS. I had daily attacks which made it difficult to do many things that weren't close to a bathroom. After taking this the episodes stopped. After years and years of trying different prescription drugs to stop the problem all I really needed was Dextrin. No more IBS. Read more

This stuff is as good, if not better, than Benefiber and is way more cost effective. Highly recommend. Read more

It works well! ;-) It is ideal for those who have to sit most of the day. Read more

A great replacement for Benefiber. Cheaper as well. Read more

This supplier doesn't use sticky tape to hold the three containers together. The Sticky tape leaves sticky areas on the containers. Very annoying. Read more
