Stupendous! Amazing!

It’s says there is not taste but honestly it dissolves like magic without an aftertaste! I have found it so helpful since I started taking it, I am more regular and hands down it’s the best fiber supplement I have ever had! 100 stars!!!

Fiberus is Morphus's gentle, soluble prebiotic fiber blend, formulated to help support digestion, regularity, and gut comfort, three of the most common things women say start to shift in perimenopause and menopause. Unflavored, dissolves clear, and easy to add to anything you're already drinking or making.

Why fiber matters in midlife

Most women aren't getting close to the daily fiber target, and as hormones shift, the gut tends to let you know. Bloating, irregular days, and a general sense that things just don't feel quite right are all common. You may notice changes in your digestion: different bowel movements, more sensitivity, or unpredictable days. Soluble prebiotic fiber feeds the good bacteria in your gut and helps support a healthy, comfortable digestive routine.

What's inside

  • 6.5 grams of Sunfiber® guar fiber per serving, a soluble prebiotic fiber chosen specifically because it dissolves cleanly in water, coffee, smoothies, or recipes, with no grit and no taste. One ingredient, nothing else.
  • Unflavored and invisible: once dissolved, you won't see it, taste it, or feel it changing the texture of your food.
  • Gentle on the gut, and made for consistent daily use. Start with a quarter scoop and build up as your body adjusts.

What it may help support

  • Regularity and healthy bowel movements, including changes in stool consistency that are common in perimenopause
  • Everyday digestive comfort
  • A healthy gut microbiome through prebiotic fiber

How to use Fiberus

  • Drink it: stir into water, coffee, tea, or your morning smoothie.
  • Cook and bake with it: dissolve in liquid first, then add to oatmeal, sauces, soups, baked goods, or anywhere you want to quietly boost the fiber content.
  • Pair it with hydration, since fiber works best when you drink plenty of water throughout the day.

Built for the long haul

Fiberus is designed to fit into a daily routine you can keep up with over time. It is formulated to help support daily digestive comfort as part of a consistent routine, which is really the whole point of a fiber supplement: you take it, you keep taking it, and it quietly does its job in the background.

Looking for the full daily routine? Fiberus pairs beautifully with Magnesium and Omega 3-T in our Essential Starter Bundle.

Your gut does more than digest food. It plays a role in how well you absorb nutrients, how balanced your energy feels throughout the day, and even how your immune system functions. Prebiotics like Fiberus help nourish the beneficial bacteria that keep this system running smoothly.

Unlike fiber supplements that feel like a chore, Fiberus disappears into whatever you're already eating or drinking. Stir it into your morning coffee, blend it into a smoothie, mix it into soup, or bake it into muffins. Dissolve it in liquid first for the best results. You'll get the benefits of 6.5 grams of fiber without noticing it's there.

Ingredient: Sunfiber® Guar Fiber

Free from dairy, lactose, soy, gluten, and eggs.

Product labels, packaging, and materials may contain additional information not shown here. Always read labels, warnings, and directions before using any supplement.

Start by dissolving ¼ to ½ scoop into 6 to 8 oz of water or any hot or cold beverage. Gradually work your way up to 1 scoop daily as your body adjusts.

Avoid adding Fiberus to carbonated drinks, as the bubbles prevent it from dissolving properly.

How much fiber do I need in a day?

Women need about 25 grams of fiber a day, and about 21 grams from age 51 (Institute of Medicine). Vegetables, fruit, beans and whole grains are the place to start. 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.

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 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 (every day), the more it has a chance to work its way through your digestive tract.

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. Start with 1/4 scoop and work your way up to a full one.

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.

Can I take it more than once a day?

Yes, you can split your daily scoop into smaller amounts through the day. Just keep the total to 1 scoop a day, and build up slowly. 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.

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.

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

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

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.

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

Yes! It is certified by Monash 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 one scoop?

Each scoop of Fiberus equals roughly 3 teaspoons.

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: Sunfiber® guar fiber.

Does Fiberus contain psyllium?

No. Fiberus contains one ingredient: Sunfiber® guar fiber. We chose guar fiber because it dissolves completely and invisibly into hot or cold liquid, with no grit, no thickening, and no taste, which makes it a lot easier to actually take every day. Psyllium is another well known soluble fiber, and it simply behaves differently: it has a noticeable texture, it thickens quickly, and it needs to be taken with plenty of liquid. Both are soluble fibers. We built Fiberus around the one that disappears into your coffee.

Can men use Fiberus?

Yes, they can.

Do you have any tips for everyday digestive comfort?

Yes, we do. Here are 14 tips for gas and bloating in perimenopause and menopause.

Of all my perimenopausal symptoms the changes in GI were the most frustrating. I am physically active, eat healthy, and my GI just became very strange and unreliable. Fiberus has been an amazing product and has stabilized my GI. I am so, so, grateful! I will absolutely take this forever.

That is so awesome! Thank you for the excellent review. We love hearing that. xo ~ Andrea, Co-founder of Morphus

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

Fiberus dissolves well, is tasteless, & easy on tummy.

Since I’ve been having tummy troubles with certain foods, I allowed myself 5 days to work my way up to a full scoop of Fiberus. Guess what! No belly discomfort!!

I love how it completely dissolves in an 8oz glass of water with the mix of a spoon AND that it has no taste. BONUS - I get 8oz of water in towards my daily water intake.

Truly a great product.

Thank you so much for your review Kristina! I am so happy to hear how much you are enjoying Fiberus. It is really a remarkable product with a ton of research behind it. I love that you started with a smaller amount and increased it to a full scoop slowly. Keep us posted on how you continue to love using it. xo ~ Andrea

AMAZING company!

I’ve gone through most of my life without health problems until I hit menopause. Boy did it throw me for a scary loop! So thankful to have serendipitously come across Andrea Donsky’s lives on tiktok. What a wealth of information about peri/menopuase that I had gone my whole life and never knew! ( podcasts are fabulous as well!)
Suddenly finding myself with GI/digestive problems (as well as a slew of other meno symptoms ) at age 51 and many unanswered questions from my GP and Gastro drs, I am so thankful for Morphus.
Andrea has been so helpful and knowledgeable about helping me find the right fiber dose for me and even offering alternative options if needed.
Fiberus is so easy to use. It dissolves instantly and no flavor at all. Packaged perfectly as well.
So grateful to this AMAZING company and for they do for educating women. They truly are passionate about what they do.

Thank you SO much Jennifer for your kind review. It really means a lot to me. I'm thrilled you found me on TikTok and you love Fiberus as much as I do. ~ Andrea xoxo
