Works well, but is now too expensive...
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
The "No added sweeteners" has been my go-to version of Metamucil, but I'm giving it 4 stars and moving on to another brand as the price is over $35 which is too much imo...

I like the mildly tart taste of this unflavored, unsweetened drink made up with water.
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I like the mildly tart taste of this unflavored, unsweetened drink made up with water. The texture doesn't bother me, with stirring right from the beginning of adding the water, there is no clumping. After 10 days there is no effect on my bowels which were regular previously anyway. My doctor wanted me to use this although I already have a high fiber diet.

Definitely Not Unflavored. This is Tart / Sour, Which Limits the Options to Certain Juices
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was expecting an unflavored fiber powder. However, expect a sour/tart taste. This means you can't add it to tea or coffee. I don't think it is appropriate to say that it is "unflavored" as I've had psyllium husk from other vendors that are truly "unflavored" (i.e. no citric acid). Dextrin (another fiber source) is also unflavored. But this Metamucil is tart (like sucking a lime) and can only be added to tart juices like orange juice or lemonade.

Happy it is unflavored
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was worried about the taste based on some of the reviews. I tried it in my coffee, and I'm glad I did it that way. I keep coffee in the fridge, so that is what I mixed with one tablespoon of this. I use half and half and no sugar. I tasted it. It tastes like burnt coffee. Not a bad thing...thats just what the taste it added. I decided to see what would happen if I added a splash of a flavored creamer. The taste went away instantly. Hope this helps someone!

Great for my tidy mind. Now the cabinet is organized and clean. Space saving too
Size: Left Facing, Size: Left Facing
Easy install. Glides nicely holds the jars without much movement. The labels are wonderful. I am super pleased. We bought 4 left facing for our cabinet. Not done replacing all the jars and such. But you can see a good idea how it will be. The fit out needs perfectly and looks great. I really like how neat and good visibility too. They seem sturdy with all the weight of the filled bottles also.
