No flavor or taste and works well!
I use this in smoothies I make for me and my husband. There is absolutely no unpleasant flavor or taste and it helps thing to move along. A good product!

Fiber BLAST!
Fabulous way to get a ton of fiber each day. Mix it into your Stanley at the start of the day – add water throughout the day. Great product. Tasteless. Mixes well.
Paisley –
Good fiber product
A suitable substitute for my usual product. High quality contents, mixes fairly well, it does have a mildly earthy flavor to it. A bit pricier than similar products of the same quality. I’d buy it again if my usual product isn’t in stock at my local nutrition shop.

Great product just not for me
I liked the product, no taste was able to mix with anything, however I noticed after a few days I was beginning to itch, I stopped it for a few days and the itch went away, but when I restarted it the itch came back.

short 5 days worth of servings
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.

Highly Effective w. No Gas or Bloating
This fiber supplement is highly effective without nasty side effects. I’m now on a medication that causes bad constipation. I eat lots of fiber rich food but it wasn’t enough. I tried many of the more common supplements but they caused me to have horrible gas and bloating as they contained ingredients like husk or wheat that ferments in your stomach. Thorne’s ingredients do not cause ANY bloating or gas. It is gentle yet highly effective. The reason for the four stars instead of five is that it is not tasteless as they claim and to me has a rather mild but unpleasant taste. I manage that by putting some Milo flavor drops in the water that I mix it in – mixing it in juice or other flavored drink would work too. But for me it’s worth 30 seconds of a mildly unpleasant taste to finally be regular without the gas & bloating. And yes it is expensive. However I only need 1/2 scoop every other day so it actually lasts much longer.

Working well! Will buy again
Works well and is helping to keep me regular and helping me detox excess estrogen. It is kind of hard to mix in water but I use a hand frother and even then it can get clumpy. Some people complain about the taste but I don’t mind it.. it’s kinda of sweet and oaty or something

Goes down easy and tastes great. I mix it with warm water and add in my collagen and creatine powders.
