Great value
This is 1 of those items that would take months to give a fair assessment. It takes time for things like this to get into your system. This was a vine item and I wanted to try them as fiber is very important after 50. But I can not speak to the effectiveness. I hope and expect there would be no side effects. Texture seems normal for something like this. Not sure if theres a odor. But seems a good value. Not sure about taste either.

A decent tasting Metamucil that does the job efficiently
Size: 1.86 Pound (Pack of 1)
The Metamucil powder inside does the job very well. I only need to take once a week in to maintain a consistency of bowel movement throughout the week. The flavor is decent as well. It doesn’t overdo so that I feel a good balance.

Easy way to add collagen to your daily fiber
Size: 1.86 Pound (Pack of 1)
I find taking a lot of supplements boring. I do take Metamucil daily. Even though I eat a lot of salad and fruit, I find this is a helpful habit. The flavor is a bit different but not objectionable.

Works great - just so expensive!
Size: 1.86 Pound (Pack of 1)
This stuff works great. I take it twice a day. But it is so expensive - not sure why.
