Good flavor
Size: 1.45 Pound (Pack of 1)
Good flavor. I quit drinking Metamucil in the past because I didn't like the orange. I was reluctant to try a different flavor but after reading many positive comments about this one I decided to try it. I was not disappointed. Thank you to all who left positive comments about the Berry flavor.

This could really be a life changer for you. It was for me.
Size: 1.46 Pound (Pack of 1)
I was having a real problem with severe constipation caused by medication I am taking. I mean it got scary bad and I was really worried if the rest of my life would have this problem. I made the mistake of thinking a laxative was the answer, although it did bring temporary relief (that one time), it was a mess to say the least. I talked to my physician about this problem and he said do not take the laxatives (they are an irritant), but to try a fiber product such as Metamucil. I thought Metamucil was for "old people", for "sick people" and such. So I got on Amazon (of course) and bought this product and started using it exactly as the instructions say to.
It has been an AMAZING transformation. Very quickly, my constipation problem began to go away until it was never a problem again. I noticed that I became much more healthier in my digestive system. It worked better, felt better and I am sure it was MUCH BETTER for my body health wise. I have to say that I was a little put off by some of the moderately graphic phrases that some reviewers said such as "cleanest wipe you will ever have" and "smooth as butter" and whatever. BUT, these people were exactly correct. The things that they said were completely true. I will get graphic myself since I want people to know. When you go, you will know it is time, and there is no running to the bathroom suddenly. There is no struggle, no waiting, no straining. You just go and everything comes out just the way it should. Very easy. Now, when you do use that toilet paper, you will be amazed that there just is no "residue" on that paper. Clean as a whistle both on the paper and your down under. Honestly, I don't know how or why, it just is.
This product will change your life for the better in several ways. Your daily functioning will be much smoother. You will probably lose some inches from the waist. Your bloodwork results will probably be more positive. You will be healthier. I wish I had known about this product a long time ago! What other things are out there that I should have know about, I wonder!
The orange sugar free tastes great, like Tang or even orange juice. I put a heaping teaspoon of powder in a normal sized glass of water, stir it immediately and down the hatch. I stir again halfway down to make sure there is not a bunch waiting for me at the bottom of the glass. I don't mind the taste or the grit or anything. It's all good. I love this stuff and what it does for me! I will be using it for the rest of my life.

Recommended by my M.D.
Size: 1.46 Pound (Pack of 1)
My M.D. told me to use this daily. It tastes a bit like "Tang" but that's fine. The fiber is good for regular bowel movements, but it also gives you a feeling of fullness which is helpful in reducing hunger sensations. So, it can help with weight loss. Be sure you get the sugar-free.
