Sweet but good.
Size: 1.45 Pound (Pack of 1)
Make sure to buy flavorless fibers as well and blend together with this one at least 50/50 if not 25/75 since it's very flavorful and very sweet with not so healthy sweeteners.

Tell R&D to find a new flavor house, this tastes awful
Size: 1.45 Pound (Pack of 1)
This “berry” flavor tastes astoundingly terrible. It is a wonder to me that this could have passed any product development team. It is like the worst kind of cough medicine mixed with bitter off notes, and it is a very strong flavor, so it is very in your face. The orange original is not great tasting but not bad, you would assume they would only release a new flavor if it was better. They ought to call a flavor house and reformulate this, the technology exists to make this taste good, but wow, this is really unpleasant.

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.

Great Product, Works as Advertised
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
This product works exactly as described. It makes BM's smoother and gentler. I personally use the unflavored, no sweeteners added version, and honestly, it does not taste very good, but I feel that the results are worth it, and I do not like adding extra sweeteners or flavorings to my diet. I have used this product for many years and have found that about 1 1/2 to 2 tbsps in 12 ounces of water works the best for me. You will need to experiment a bit to find the ratio that works best for you. I recommend that you start on the low side and gradually increase the amount of Metamucil as needed.
