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.

Delicious and easy to chew probiotic gummies that also add fiber to your diet!
i just received this package of probiotic fiber gummies and can assure you that they taste terrific!
The container is easy to open and includes an internal seal both to assure freshness and the safety of the product.
These are individual gummies that are easy to chew and taste yummy! One flavor is citrusy and another has a berry flavor. Chewing them was not at all difficult and I did not feel like I ended up with lots of residual product stuck in my teeth.
Each serving of 3 gummies provides 6 grams of fiber which is an additional benefit to the probiotics! The recommended dose is 3-6 gummies per day. As well as being flavorful and easy to chew, the addition of fiber is a great benefit for most people’s diets!
I am a healthy woman of “a certain age” as the French say. I don’t have specific health problems that I know of but I am trying in general to maintain a healthy lifestyle. That was my goal in acquiring this product.
This is the first day I have eaten and enjoyed these probiotic gummies. Of course I have not experienced any health benefits yet but my initial experience eating these soft gummies has been extremely positive!
If you are interested in adding probiotics or fiber to your diet, I encourage you to purchase these inexpensive, delicious and easy to chew gummies!

Tastes Great!
I’ve tried a lot of fiber supplements over the years, and these are honestly one of the easiest ones to stick with consistently. The biggest thing for me is that they actually taste good. The Citrus Berry Splash flavor is pleasant without being overly sweet or having that weird artificial vitamin aftertaste some gummies have.
They’re soft and easy to chew too. Some fiber gummies can be oddly hard or stick to your teeth, but these have a good texture and are easy to take daily.
What I really appreciate is the convenience. It’s so much easier for me to remember gummies than mixing powders into drinks all the time. I can just take them quickly in the morning or after dinner and be done with it.
After using them consistently, I’ve noticed they help keep things more regular without feeling harsh or causing the kind of stomach discomfort some fiber products can. They feel gentler compared to a lot of other options I’ve tried.
The large bottle is another plus. With 126 gummies, it lasts quite a while, so even though the upfront cost might seem a little high, I think the value is pretty reasonable for how long they last.
I also like that they’re a simple way to add a little extra support to my routine, especially on days where my diet probably isn’t perfect.
Overall, easy to take, good flavor, gentle on the stomach, and something I’ll continue buying.
