Hard to swallow
Size: 84 Count (Pack of 1)
This pill should have been in a tumbler or something to make it smooth like others. Otherwise I've had no issies or side effects. I'll continue to buy it, but i with it was more smooth to swallow.

Works great.
Size: 84 Count (Pack of 1)
Like the tablets much more than the powder, but need to take 3 fairly large tablets. If I could remember to take it 3 times a day, it wouldn't be bad, but I take 3 all together. A little hard to get down.

Easy tasty way to support digestive health
PSA- You need more fiber.
I've been using these prebiotic fiber gummies for a while now, and overall I've had a very positive experience. The Citrus Berry Splash flavor is genuinely enjoyable, which makes them much easier to take consistently than some other fiber supplements I've tried. I also love the convenience I keep the bottle on my coffee table and have them after dinner when I watch TV.
I've noticed that they help support regularity when taken consistently, and I like knowing that they contain prebiotic fiber to help nourish beneficial gut bacteria. For me, these gummies work best as part of an ongoing digestive health routine rather than as a quick solution when I'm already feeling backed up. In those situations, I personally find fiber powders to be a bit more effective. However, that's not really the purpose of these gummies—they're designed to help maintain digestive health and regularity over time, and I think they do that well.
The gummies tend to stick together in the bottle, especially once I've gotten about halfway through it. I've found that storing the bottle upside down helps prevent them from clumping too much and makes them easier to grab.
Overall, these are a great option if you're looking for a tasty, convenient fiber supplement that's easy to stick with long term. They've helped me maintain regularity, taste great, and are much easier to incorporate into a busy schedule than many other fiber products. I would definitely purchase them again.
