Nutricology Dietary Fiber Powder - 2000mg Insoluble Fiber Supplement, Microcrystalline Cellulose Powder, Powdered Cellulose, Non-Fermentable, Hypoallergenic - 8.8 Oz

This is my second purchase. When you put it in water and let it dissolve, its taste does indeed resemble chalk. But for me, its effect is much better than that of psyllium husk. I am extremely satisfied.

This fiber is essential, and often seems more useful to me than soluble fiber. But, a balance of both is very important in any form of diet, whether from supplements like this and/or from food. The folks leaving bad reviews may not understand the nature of INsoluble fiber. It's going to keep its form, it will be gritty a bit, and it's NOT going to mix well in water. It's INSOLUBLE fiber. Same as in any food, it's what moves stuff through your system like a "broom". It speeds transit. Soluble MIXES and/or becomes gel-like in some cases, slowing digestion, adding bulk to doo doo. Both are useful and needed for normal function. Just understand that insoluble fiber isn't a "mix in water to dissolve" sort of thing. If you drink it fast, or mix it with, say, smoothies or something, it's fine. UPDATED: This has now priced itself out of sustainability for me. I'm now achieving same sorts of results and function buying NuNaturals Oat Fiber, which per ounce, or pound, is much cheaper, I get more insoluble fiber per like amount...AND, with oat fiber, I can bake with it, put it in smoothies, etc.

Regularity. Thats what it is for and does it very well. Takes about 12 -36 hours for it move through the digestive track depending upon how fast your digestion is. It help eliminate any existing bloat or cramps as it moves through the intestines. I feel that it almost scrubs off the inner walls of the gunk and removes from the system. If you eat a lot of dairy (cheese, mild, yogurt etc), or too much sugary products, then you may have noticed that the next day bowels are not emptied well. But if you take 2 doses of this supplement, you will feel your system cleaned out. There is no discomfort. Tasteless and easy to take. Mix vigorously with cool water and drink it down. Easy. It also gives me a full feeling in stomach so that I do not eat too much.

Not for me. Taste like chalk Didn't do anything after 3 days in a row drinking it twice a day. Easy to mix Value for the money, nope

This product does what I needed it to do. Keep me regular. The texture is the only thing displeasing about this, which I only notice when drinking it in a glass of water. Helps to drink it with a straw. Other drinks I don't notice it as much. Good buy if you suffer from constipation and if you're not regular. I would stay away from this if you are pretty regular or have normally more watery stools.

Adequate methylcellulose fiber supplement. Less expensive than premium Dr. Natura, but the grind is not as fine, making it less easily dispersible in liquids and a bit gritty when mixed. Should be fine, however, when used in cooking. No flavorings, sweeteners, or other fillers.

Been using it with our cavapoo for years. She is so regular!

I only drink insoluble fiber going on 6 years. That being said this formula smells like a strong chemical and has a weird sour sweet taste that goes with nothing. It is very gritty like sand too but that is ok and tolerable because its supposed to be insoluble BUT the flavor, seriously is intolerable, run from this one folks. There is another brand out there that has no smell, no taste, and is way less gritty. If you need something to mix with your drink or food and you don't want to taste it then this is not it. This stuff can't be put in anything without changing its flavor into a chemical type taste. They need to remove the smell and taste from this product. There's better out there.
