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.

This stuff works great. I take it twice a day. But it is so expensive - not sure why.
