We carefully selected real food ingredients for a better choice product. See why we included some of these key ingredients:

Fructooligosaccharides, Hydrolyzed Guar Fiber, Organic Apple Fiber, Inulin (Chicory Root)

Fiber that does more than just help digestion. A smooth, non-gritty blend of prebiotic fibers to nourish your microbiome and support your body's natural GLP-1 response, promoting fullness and overall metabolic health.

Shake
Add 1 scoop of fiber powder with 10-12oz of your drink of choice in a shaker bottle and shake.

Stir
Add 1 scoop of fiber powder with 10-12oz of your drink of choice into a glass and stir.

Some people may experience mild gas or bloating when increasing fiber intake. To minimize discomfort, start with a smaller serving and increase gradually.

Our quality assurance process for our nutritional and supplement products begins with collecting, from our suppliers, Certificates of Analysis (COAs) for our ingredients. We then retest the final product blend. We share our COAs because we believe the results are worth sharing.

Frequently Asked Questions

Some traditional fiber powders can begin to clump over time. We have not found this to be the case with our fiber powder. It mixes smoothly when added to water or your favorite beverage.

For some people, a full serving works just fine. However, if your gut is not used to higher amounts of fiber, you may experience some stomach discomfort. If that happens, we recommend starting with one-third to one-half of a serving and consuming it with food. You can gradually increase to a full serving as your body adjusts.

No, there is no added sugar, flavor, or added sweetness. It can be blended or mixed into any drink.

Just Ingredients Fiber Drink contains both soluble and insoluble fiber: fructooligosaccharides (a soluble, prebiotic fiber), hydrolyzed guar fiber (a soluble fiber that contributes to digestive regularity), organic apple fiber (an insoluble fiber that promotes digestive comfort), and inulin (a soluble plant fiber).

Reviews

Love the plain flavor

"I love being able to add this to my morning drink of protein, collagen, creatine and now fiber. Easy and ready for the day! My drink tastes like the JI protein flavor of the season and the rest is flavorless but still fuels my body."

— Jessica D. (5/5)

Another Super Product

"I have been using this product for about 1 month. I add a scoop daily to my lunch time smoothie. I wouldn't even know it is in there. No taste, no grittiness, just plain fiber that aids in digestion and overall wellness. Thanks Just Ingredients!"

— Sharon S. (5/5)

Fiber drink

"I have to admit I was on the fence about ordering this but when I travel it is difficult to get enough fiber so I decided to give it a try. Oh my goodness it works! It gives you a little boost of fiber for your gut health and I really do like it and will be ordering again."

— Sears (5/5)

Works great

"I’ve been using this during my pregnancy and anyone who has been pregnant understands the constipation that comes. This fiber has helped me stay regular each day. I mix it into the hot chocolate mix or the bone broth protein powder in the morning."

— LONG (5/5)

Love it!

"I love the plain because I mix it with my collagen. It mixes well and doesn't clump. I do give my drink a swish before drinking if it sat for awhile as it can separate a bit. I use half a scoop to start. No bloating!"

— Lisa A. (5/5)

I struggle to eat enough

"I struggle to eat enough fiber each day and was looking to find a plain fiber supplement to add to my smoothie each day. This one is plain and doesn't have any added citric acid. I blend some into my chocolate peanut butter banana protein smoothie every night after dinner as my dessert. Yum! My whole family enjoys it! Also, the closure on the bag is wonderful! I don't know why all bags don't close this way! It's like food appropriate velcro. Haha"

— Rachel P. (5/5)

Fiber

"This has been a staple in my and my mom's routine! We both struggle with fiber intake and this has been so helpful. We just add it to our yogurt every morning and it gives us a good head start to our day!"

— Andrea T. (5/5)

Helpful

"I love how I can put it in any drink that I choose and it’s making my body work better. I just added it to my electrolytes. I didn’t realize how important fiber was and it really makes my gut feel better."

— Sarah L. (5/5)

Easy product

"This product is great! It's great for days when fiber intake is a little shy of the mark. It mixes nicely with other drinks."

— Jennifer B. (4/5)

Up your fiber!

"Fiber has always been difficult for me to get enough of in my regular diet. This supplement works great!"

Q&A

Can the plain fiber mix be used in hot coffee without ruining the fiber?
Hi! Yes, our Fiber Drink can absolutely be added to hot beverages. It mixes well into warm drinks like coffee, tea, or hot water. We recommend stirring well and avoiding boiling temperatures when possible, as very high heat can sometimes affect the texture.
Can this be consumed while breastfeeding?
For pregnancy and breastfeeding, we always recommend consulting with your doctor to determine what is best for your individual needs. While there are no ingredients in this formula that we specifically identify as contraindicated during pregnancy or breastfeeding, we recommend checking with your doctor or healthcare provider before using the product. Pregnancy can change nutritional and supplement needs, and your healthcare provider can review the complete ingredient list and your individual circumstances to determine whether it is appropriate for you.
Can you mix the fiber and protein powders together in the same drink?
Yes you can add them all together!
Is the fiber drink mix safe for kids?
Great question! This product is generally safe for children when used as directed.The ingredients are made from organic fruits, plant-based fibers, and natural sweeteners that are commonly used in kid-friendly foods.​ That said, each serving contains 6 grams of fiber, which can be a significant amount for younger children. We recommend starting with a smaller serving, especially for kids under 8, and making sure they drink plenty of water. Introducing fiber gradually can help avoid temporary digestive discomfort like gas or bloating. We always recommend checking with their pediatrician first before introducing new supplements.​
Can this be combined with either the probiotic complex or nighttime relax? Trying to get all 3 into my kid each day and wondering what, if anything, would be best to combine.
Yes this could be mixed with the Probiotic Complex or Nighttime Relax! We would just recommend reaching out to your doctor if you have any questions on how much fiber to give your child.
