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. These are 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 about it. Bloating, irregular days, and a general sense that things just don't feel quite right are all common. Soluble prebiotic fiber feeds the good bacteria in your gut and helps support a healthy, comfortable digestive routine.

What's inside

  • Soluble prebiotic fiber, chosen specifically because it dissolves cleanly in water, coffee, smoothies, or recipes, with no grit and no taste.
  • 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, formulated to support consistent daily use without the bloat or harsh feel of some fiber supplements.

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 with plenty of water through the day.

Why women keep reordering

Most women tell us Fiberus is the supplement they didn't realize they needed until they started using it. The shift in how their day feels, fewer "ugh" mornings, less bloat, more comfort, is the kind of small, steady change that adds up.

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?

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.

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. 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.

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?

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.

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 7 grams?

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: 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.

Can men use Fiberus?

Yes, they can.

Do you have any tips to help with gas and bloating?

Yes, we do. Here are 14 Tips to Banish Gas and Bloating in Perimenopause and Menopause.
