Kirkland Signature OPTIFIBER, 26.8 oz

This product works very very well, the price is absolutely affordable. I have no problems with this product, it is very effective.

I've been buying this Kirkland Signature fiber for many years and use it every day. The fiber is tasteless and melts in both hot and cold liquids (though hot is quicker). I really like the container - the snap-open/close lid is much easier than a traditional turning lid, especially when using it daily. I keep it right next to my coffee maker, which makes it easy to add a consistent dose of fiber to my diet.

Optifiber has been a true lifesaver for my digestive health! Since I started using it, my bathroom routine has transformed completely. This fiber supplement is incredibly effective, making it easier than ever to maintain regularity and promote overall gut health. What I appreciate most about Optifiber is its gentle yet powerful formula. It blends seamlessly into my daily routine—whether I mix it into my morning smoothie, yogurt, or even just a glass of water, it dissolves without any gritty texture. I love that I can easily incorporate it into my meals without altering the taste. The results have been remarkable. I’ve noticed a significant improvement in my digestion, and I feel lighter and more comfortable throughout the day. No more bloating or discomfort! It’s reassuring to know that I’m supporting my digestive system with a product that’s both effective and easy to use. Optifiber has truly made a positive impact on my life, and I can’t recommend it enough to anyone looking to enhance their digestive health. If you’re seeking a reliable and efficient way to keep things moving smoothly, Optifiber is the way to go!

Mixes well with hot tea or coffee.

This product is intended to aid in avoiding constipation, by increasing the amount of water retained in the solid waste moving through the intestines. It does what it claims to do. The white powder dissolves easily in any drinkable liquid, or it can be mixed into soft foods, like mashed potatoes. I sprinkle it on my breakfast cereal. Be careful with carbonated drinks; it can cause excess foaming. When used in water it is almost but not quite totally clear and tasteless.If you use significantly less water than indicated, as in less than a cup, there is the faintest yellow coloring, and a very mild taste. When mixed according to directions, you won't notice either the color or the flavor. If you use it in anything that has more color or flavor than pure water, like milk, juice, kool-aid, etc., you won't notice any effect on either the color or flavor. This does not thicken or "gummy" the water. And, this is a whole lot less expensive than the name brand of the same thing.

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’ve tried other brands, but this is the best value, easy to mix, and less taste than those claiming to be without taste. I also like the larger container, since this is something I take daily.

I fought using this type of product. My experience with the Metamucil powder found that it easily clumped and I didn't want that again. My doctor provided me with a list of options, with Kirkland being one of them. The powder is much silkier and DOES NOT CLUMP! There is no flavor and goes down easily with whatever I mix it with (usually Lactaid). Additionally, when checking the price on Costco, I found Amazon's price to be the same and it had free shipping. Seriously a no brainer purchase!

臭いも無く、普通に飲めます。 コーヒー、紅茶、ヨーグルトなどに混ぜて大丈夫です。 ちゃんとトイレ行くようになります。
