Fiberus is an unflavored soluble prebiotic fiber made from guar fiber. Each serving contains 6.5 grams of fiber that dissolves clearly, quickly and easily into hot or cold liquid, and doesn’t have any taste, texture, or smell. It also won’t clump or thicken. Fiberus helps to keep food moving through the digestive tract therefore improving both occasional constipation and occasional diarrhea without excess gas, cramping or bloating. Fiberus helps to lower the glycemic index of foods, and helps to support healthy weight management by reducing hunger. It can also help to improve the absorption of essential minerals.

Fiberus is excellent for women in perimenopause and menopause, as well as anyone over the age of nine months looking to support their digestive health.

Prebiotics help to feed the good bacteria in our gut, promoting healthy gut flora, which in turn promotes healthy digestive health and overall wellness. You can add Fiberus to cooking and baking to increase the fiber content of those foods (just be sure it’s dissolved beforehand so you don’t get any clumps) as it won't change the taste or texture of the food or liquid you put it in. Once added to liquid, it turns invisible so you won’t even know it’s there!

Sunfiber® Guar Fiber

*Actual product labels, packaging and materials may contain more and different information than what is shown on our website. We recommend you don't rely solely on the information presented here, and that you always read labels, warnings, and directions before using or consuming any of our supplements.

Dissolve ¼ to ½ scoop into 6-8 oz of water or any hot or cold liquid of your choice. Work your way up to 1 scoop daily. (Note: We don’t recommend adding it to carbonated beverages since the bubbles impact its ability to dissolve properly.)

How much fiber do I need in a day?

We recommend aiming for 25 to 35 grams of fiber a day by eating a variety of fruits and vegetables. Since many of us don’t get the amount of fiber we need, supplementing with a soluble fiber can help you to reach that goal.

Can I take it more than once a day?

You can safely take Fiberus more than once a day, but be sure to build up your tolerance to the added fiber. We don’t recommend using Fiberus as your only source of fiber. The bulk of your daily fiber should come from your diet including a rainbow assortment of fruits and vegetables.

Why do you recommend starting with ¼ to ½ scoop?

It’s always a good idea to start slowly when taking a fiber supplement.

How much water should I drink with it?

We recommend drinking lots of water and/or caffeine-free liquids when taking any fiber supplement as it will help to hydrate your digestive tract and help to move things along.

Can I add it to my morning coffee?

Yes! You can add it to coffee, tea, soups, yogurt, smoothies, water, and any hot or cold liquid of your choice.

How long will it take to start working?

You may see a difference as early as the first week. Consistency is key, the more you take it, the more it has a chance to work its way through your digestive tract.

Can I take Fiberus if I follow a LOW FODMAP diet?

Yes! It is certified by Monashe University.

Can I bake with Fiberus?

Yes! You can add Fiberus to whatever you are cooking and baking to increase the fiber content of those foods (just be sure it’s dissolved beforehand so you don’t get any clumps).

How many teaspoons is 7 grams?

Each scoop of Fiberus equals roughly 3 teaspoons.

Can I take ½ a scoop in the morning and half at night?

Yes! You can split the dose and still get the same effects.

How long does it take Fiberus (the powder) to dissolve?

It takes about 60 seconds or less for the powder to completely dissolve.

What makes Fiberus different from other fiber supplements?

We believe fiber supplements should not contain any unnecessary ingredients such as food coloring, artificial flavoring, artificial sweeteners or preservatives. Fiberus only contains one ingredient: guar fiber.

Does Fiberus contain psyllium?

Psyllium is a popular form of soluble fiber however it comes with several downsides. For example, popular nutrition protocols advise against eating psyllium, there have been reports of allergic reactions, it can block the colon if not enough water is consumed when taking psyllium, it is not recommended for people who had bowel surgery, and psyllium contains phytates. Phytates (or phytic acid) bind to minerals (like zinc, iron and manganese) and can decrease the absorption of these minerals in the body. While psyllium has been shown to help relieve constipation, there are other products on the market, like Fiberus, that has a similar effect but without the negative side effects.

What is the best time of the day to take Fiberus?

You can take Fiberus anytime of the day (whenever you remember). Establishing a routine is best (ie. with your morning coffee, tea or water, or at dinner). You can add it to foods as well (soup, yogurt, smoothies, etc.). Feel free to play around with when to take it and always listen to your body to see what it likes best. You shouldn't get any gas or bloating from taking it. Start with 1/4 scoop and work your way up to a full one. You can even increase it from there if need be.

Truly the Best Fiber supplement!

I am so pleased with this fiber supplement. It worked well for me and was so gentle and Iight that I recommended it to a few of my nutrition clients. They all experienced good results but the best testimonial came from a client who had experienced constipation since childhood. She had tried butyric acid, an herbal supplement, and other clean products with some success but nothing worked as completely as the Fiberus. She thanked me every day for 7 days straight. This is a great formula!

Hi CG. Wow, wow, wow!! Thank you so much for your feedback as well as your clients. I'm so happy to hear it's working so well for all of you. Knowing we're helping all of you on this journey is what keeps our passion going. ~ Andrea, Co-founder, Morphus

Life saver!

I recently started a medication that made me constipated (TMI) and went through two other fibers and was still miserable. Finally tried this one that a friend recommended and oh my gosh. It works so well and I feel amazing! I can't get over the difference in this brand vs others that are supposedly without fillers and "good" for you. I'll be a customer for life! Thank you!!!

Thank you so much Charlotte for this amazing review!! We are thrilled to hear how much Fiberus is helping you with going to the bathroom and your gut health. No bathroom talk is TMI on our website! LOL (it's my favorite thing to talk about as a nutritionist!). We appreciate you and your business. Please let us know if you have any questions. ~ Andrea, Co-founder Morphus xo

A safe, effective way to add healthy fiber to your diet

Fiberus is a fabulous product! I love it and love to recommend it to my thyroid health clients.

Most fiber supplements on the market taste terrible or have an awful "mouth-feel" Some even make your gut health worse, by adding too much or the wrong kind of bulk, leaving you feeling gassy and bloated.

But Fiberus is perfect! Not only does it have no taste and dissolve easily in water, it's make of prebiotic fiber, which nourishes the bacteria in your gut! So at the same time that it's making your digestion smooth and comfortable, it's also helping to support a healthy gut.

Thank you for ANOTHER awesome product, Morphus!

Yay!! We love hearing this feedback! Our goal was to provide a fiber that has minimal ingredients and that's backed by research, both of which check the boxes for Fiberus. Thank you for loving this product as much as we do. xo ~ Andrea, Co-founder

Even My Daughter Loves It!

I have been looking for a fiber supplement that doesn't clump and I have to "choke down". And I have found it! Fiberus is the BEST fiber supplement I have found. It dissolves completely IN WATER! Even my tweenage daughter is using it without a fuss. I recommend this for anyone.

That makes us soooo happy Dr. LaKeischa. We are thrilled that your daughter loves it too. It's super easy to take, which makes it a great option for anyone age 1 and up. ~ Andrea, Co-founder xo
