Now I know why this one was so cheap! The taste was not pleasing to me at all... I threw it away. However, I do love their other lines, with the berry flavor being the best! Orange is good too but to obtain the best flavor, 2 spoons are required (for me anyways). Also, the berry flavor (while only taking 1 spoon) is even better tasting if you add a little lemon juice to it. Finally, I read that adding lemon juice to water helps to prevent kidney stones! Who knew! This is a good product but I think they went to far trying to add "fizz".... the effect was negative while the previous products are great!

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!
