Best one yet
Best tasting Metamucil if you enjoy carbonation. Less sweet than regular (even the no added sugar version felt a bit overly sweet to me). Lemonade is a close second but a bit too expensive. Wish it would come with a scoop but I saved one from a different product and dropped it into the jar here.

Great product, dislike new 43oz size
Works well. Prefer the “fizzy” formula over all others.
I recommend adding powder to your cup, fill 30-50% with cold water, then use a small handheld milk frother to blend. It’ll “foam” then settle, add you can add more water. (If you fill the whole cup with water right away it’ll overflow when it foams up.)
I prefer to drink it quickly, before it starts to thicken into a heavy gel/paste.
3 star rating for 2 reasons:
1) Strongly dislike the food coloring!
2) They recently changed container size and shape. It used to be a 29oz cylinder, now it’s 43oz and more like a tub.
The new format is too large for my kitchen vitamin drawer + too wide and heavy to grab with one hand. (I’ve included side by side pics here - didn’t think to take them until I’d already removed the 43oz label for recycling.)
I saved my last 29oz canister and I’ve been decanting powder from the 43oz, keeping the 43oz in pantry storage.

Great product
I have been using Metamucil for a long time!
I can tell a difference in using the plain and the vitamin variety. I feel a more energetic. I will not use this variety close to bedtime.
It does fizz a lot. Only add a small amount of water to the glass and after the fizz settles down add more water.
Great product!

The best no sugar natural fiber
Even if you have no problems with your dietary system, fiber is an excellent way to protect your lower GI system. I use the no sugar version as I want the fiber, but I want the extra carbs in the regular version. Regular no sugar is fine, and has no problems with taste. Every so often, I treat myself to this better stevia sweetened version. I don’t take either one 3 times a day, as recommended, but I do take it every morning. If you like the regular sugar free version, give this a try. Since I take it every day, I do like occasionally switching to the better version.
Read the labels of your fiber supplement products, if you take them. Very few give you the amount of fiber that this does, and you control exactly how much fiber you want. If you read up on the benefits of adding to your daily fiber intake, you will wonder why you haven’t been adding this to your daily healthy supplements This is a very effective way to protect yourself, and most other products don’t come close!

Great product for bloat and regularity
This works! I try to take a big tablespoon in the morning and if Im feeling bloated maybe one at night. Within a day or two, it helps you get regular! And it makes you go..and not loose, runny stool either. It leaves with that “empty stomach” feeling. I have this set up on auto delivery. Its a bit expensive but like that it has stevia, so am willing to pay the extra. It tastes like OJ but drink it asap or it becomes thick and slime like within a few minutes.
