It was very hard to rate this product. As far as its efficacy as a fiber supplement it works better than any other product I've tried before. Having said that, its solubility is very poor. No matter what liquid I use, whether it is ice cold, room temp or warm, or for how long or vigorously I stir, the product will not mix in properly. It leaves many clumps and lumps. That isn't a big deal for me... I just drink them down! What really gets me angry is the misrepresentation that this is a 30 day supply (as is indicated on the label). The serving size is listed as two level scoops. I got 25 servings from the last container I ordered. I am a nurse and a science teacher, so believe me when I say I know how to measure properly. This product is expensive. It works very well, but to be so pricey, and then to be short 5 days worth of product is unacceptable. I will be measuring this new container and will report back on the serving count. Updated 4 July 2017: I changed my rating to one star because there is obviously a deliberate shortage of product. The first time I purchased this I noticed that it ran out too soon. The label says: Serving Size: two level scoops Serving Per Container: 30 I decided to carefully measure with the next container I purchased (see above review). It lasted from 5/16 to 6/9 = 25 doses. I know sometimes there are packaging errors, so I continued to count with the 3rd container. It lasted from 6/10 to 7/4 = 25 doses. Again. I will be contacting the company and asking them (or Amazon) for a refund for all three containers. To charge $41.10 for a one month supply of dietary fiber is ridiculous to begin with, but I bought it on the advice of my doctor. To charge $41.10 and then rip you off 5 days worth of product is completely unacceptable. I will also be informing my doctor to ask her to stop recommending this product until they treat their customers with integrity. Updated July 6th: This was the response from Thorne Research: "Thank you for reaching out! We’re sorry you didn’t have an excellent experience with our product, which is always our goal. At the time of manufacturing, each bottle of FiberMend is filled according to the weight of the powder listed on product label. Likewise, the Supplement Facts information is determined by the weight of one serving – according to the number of servings listed on the product label. However, by the time a powdered product, like FiberMend, gets to a customer, sometimes the powder will compact down – it “settles” – and therefore an individual scoop can vary in how much powder the scoop contains compared to when the powder was first manufactured. To maximize the consistency in the amount of powder each time you take a scoop of it, we recommend inverting the bottle a few times – you’re not “shaking” the powder, you’re just “fluffing” it – before each use. Plus, be sure to take care the powder is level with the top of the scoop." ***So basically the company tells me that in order to find an extra five day supply of product ($6.85 worth) I just need to "fluff" my fiber before each use. Never. Buying. Again. Read more

My daughter recommended this product for gut repair, and I’m so glad she did! I started adding it to my coffee, and four bottles later, I can’t have my coffee any other way. I love that it’s completely tasteless but adds a smooth, satisfying consistency. Best of all, it has made my stomach feel more relaxed and less tight, and it has helped keep me regular. Highly recommend for anyone looking for gentle gut support! Read more

Please read this review. First off, this product works like a charm to make you regular! ( Better than Psyllium husk) Thank you Thorne. Second, if you look up each individual ingredient and check its efficacy, you will be pleasantly surprised, I promise. Third, to all the customers that complain about not getting 30 scoops for the price...the product reviews on Thorne website suggest people flip the container over a couple of times to "re fluff" the contents and then you should get the 30 scoops. The product settles over time. Also, it mixes well with warm water. I personally loved the taste, like cream of wheat, or toasted rice. I take other Thorne vitamins, and no one paid me to write this review. I would love to know if customer can get away with taking 1/2 scoop after awhile. I have not been using it for that long.
