Kirkland Signature OPTIFIBER, 26.8 oz each, 3-pack

Very versatile and convenient fiber source, highly recommend.

Good

I've bought many of this brand. It works great for providing the fiber I need. Best price and quality.

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!

I take about 1 1/2 soon fulls a day mixed with my tea. Don’t mix it in a drink with bubbles. It keeps my digestive system functioning smoothly. I keep it all the time and I can tell when I haven’t taken it.

great product. all natural way to keep gut working on fiber i don't always get in my diet. gastroenterologist recommended years ago and have been using daily since.. Vendor isn't fast but price is fair good.

Tried after using brand name product. Dissolves well and equal in effect. Can recommend.

I have been using this for years, but never any issues at all. Always dissolves in practically every single thing, from ice water just brew hot coffee. And it’s cheaper than Benefiber.
