Feel lighter from the inside out
The fiber supplement designed for people on GLP-1 medications.
Regularity
GLP-1 medications slow the digestive process, which can lead to constipation. The three soluble fibers in this blend act like magic in your gut to keep things moving as they should.*
Gut Health
A happy gut is linked to so much: healthy digestion, a well-functioning immune system, and a balanced mood, to name a few. The probiotic strain in SoWell Fiber does it all.*
Digestive Comfort
While some forms of magnesium come with unwanted laxative side effects, the magnesium glycinate we included in SoWell Fiber gently relaxes muscles for more comfortable digestion in a way that is mild enough for daily use.*
Zero Sugar, 1g Net Carbs
While this fiber might taste like a treat, it won’t spike your blood sugar. It’s sweetened naturally with Stevia—not sugar—and features 1g net carbs, making it the perfect choice for those who are mindful about carb intake.*
Feel the Difference from Day One
Formulated to support digestion, reduce bloating, and keep things moving so your body feels lighter, more balanced, and easier to manage daily.
You may start to notice improved bowel regularity and a feeling of fullness immediately, thanks to the soluble fiber in this blend.
Day 3
Bacillus subtillis, as a probiotic, works to balance gut bacteria, potentially improving digestion, immune function, and nutrient absorption.
Day 30
Regular magnesium consumption leads to improved muscle function, reduced muscle cramps, and better overall energy levels.
Day 90
You’re reaping the long term benefits of adding fiber to your diet, supporting healthy blood sugar levels and heart health.
Clean Ingredients That Work With Your Body
A targeted blend of protein, collagen, and digestive enzymes designed to help GLP-1 users maintain muscle, support digestion, and feel their best.
Psyllium Husk
Derived from the seeds of the Plantago ovata plant, this renowned fiber promotes digestive health and regularity. It acts as a gentle bulking agent, which helps move waste through the digestive tract while supporting healthy cholesterol levels.
Guar Gum
A soluble fiber extracted from the seeds of the guar plant that can help balance stomach acid. It aids the digestive process by gently scrubbing the gut, supporting digestive health and regular bowel movements.
Apple Pectin
Another soluble fiber sourced from apples, known for its ability to support digestive health and promote a feeling of fullness. It helps regulate bowel movements and promote overall gut health.
Ceylon Cinnamon Bark
A spice renowned for its rich flavor and potential health benefits. In SoWell Fiber, it serves as a natural flavoring agent while also providing antioxidants and anti-inflammatory properties that support overall well-being.*
Bacillus Subtilis
Bacillus subtillis is a highly stable strain of bacteria that supports gut health, digestion, and immune health. We use a standardized form called Sporevia™ to ensure the highest quality and benefits.
Magnesium Glycinate
A superior form of magnesium known for its ability to calm both the body and mind without irritating the digestive tract. This essential mineral plays a crucial role in numerous bodily functions, including muscle and nerve function.*

"Usually don't like taking fiber in powder form because it often tastes weird and has a thick texture, but that all changed with SoWell Fiber. I tried it after dinner while winding down, and the Apple Cinnamon flavor was a delicious treat before bed. I mixed it with really cold water in a blender bottle, and the texture was perfect—not too thick. I also love the individually portioned packets, which make it easy to take on the go, especially when traveling. Taking fiber daily is important to keep things regular while on Zepbound, and this product also has probiotics and magnesium for a healthy gut!"

Frequently Asked Questions
Common questions about using the SoWell Protein
GLP-1s cause slowed gastric emptying, which can be both a blessing and a curse. On the plus side—it’s one of the reasons you’re not as hungry on these medications. But you don’t want things to slow down too much, or you’ll suffer from uncomfortable side effects like bloating and constipation.
That’s where fiber comes in. Experts recommend increasing both fiber and water for anyone on a GLP-1 medication to help pass waste effectively and comfortably.
But that’s not the only reason fiber is excellent for GLP-1 users. Fiber has been shown in many studies to lower the risk of excess weight, type 2 diabetes, high cholesterol, and/or heart disease. Which—aren’t these the reasons you’re on a GLP-1 in the first place? It’s a win-win.
If you’re thinking, “Oh, I’m probably eating enough fiber in my diet,” keep in mind that only 5% of Americans are meeting adequate intake levels of fiber to reap the benefits—and GLP-1 users need the right kind of fiber even more than most!
We created SoWell Fiber to make it easy for GLP-1 users to get the perfect type and amount of fiber they need to support healthy digestion on GLP-1 medications. Unlike other fiber powders, it’s made with three types of fiber—plus probiotics and magnesium glycinate—that work together to balance your gut and digestion. Our favorite part? The delicious, natural-tasting apple cinnamon flavor. (Don't knock it 'til you try it!).
The main difference between our fiber and others is that ours was designed specifically for GLP-1 users!
Because digestive issues are so common on these medications, GLP-1 users need a fiber that is gentle, yet effective, enough to be taken daily to prevent these issues. That's where SoWell Fiber comes in.
Others
Too harsh for daily use
Does nothing to specifically address the needs of GLP-1 users

A lot! Our founder, Dr. Alexandra Sowa, has clinical experience working with GLP-1 users for a decade.
This product was created using her clinical experience and all available research on GLP-1 medications.
If you really want to nerd out, you can read some of the clinical papers that went into our research process here:
“Populations that consume more dietary fiber have less chronic disease. Higher intakes of dietary fiber reduce the risk of developing several chronic diseases, including cardiovascular disease, type 2 diabetes, and some cancers, and have been associated with lower body weights. The Adequate Intake for fiber is 14 g total fiber per 1,000 kcal” “ only 5% of the population meet the Adequate Intake” Position of the Academy of Nutrition and Dietetics: Health Implications of Dietary Fiber
“Unless constipation is present, consider doses of 200 to 600 mg daily of forms of magnesium less likely to cause loose stools: magnesium glycinate (chelated magnesium),” Science Direct Magnesium Glycinate
“Sporevia is a spore-former with a protective outer layer that survives processing and the path to the gut to support digestive health.”Kerry Sporevia® Probiotic
You can take SoWell Fiber anytime, but we recommend enjoying as an after-dinner treat. The magnesium glycinate in the blend has a relaxing effect, so it can help you wind down after a long day,
While this product is designed for GLP-1 users, it's clean, safe, and beneficial for everyone to enjoy!
It may be especially helpful for anyone who is trying to limit carbs and sugar, as well as anyone who wants to reap the long-term benefits of fiber: improved blood sugar, appetite control, cardiovascular health, and of course, healthy digestion.
Also, if you hate the taste of other fiber powders, you should give this one a try! (It's SO delicious.)

The flavor of this is phenomenal. Most fiber supplements are either unflavored or berry, which doesn't allow much room for experimentation.
I tried this 3 different ways.
1). I mixed it into Greek yogurt with some peanut butter to make a protein-packed yogurt dip to go with my apple slices. This was a great afternoon snack, definitely will probably be my go-to
2). I had it like a tea. I mixed the fiber supplement with hot water in a mug. It dissolved nicely and tasted like apple cinnamon tea. It will be a go-to when it gets cold out.
3). I mixed it in with my cottage cheese, which was my least favorite. The directions are correct; you only have a certain window of time to drink/eat this supplement before it gets a weird texture.
Overall I like this a fiber supplement option!

Fiber's newest Fan
I was incredibly skeptical about taking this fiber supplement. The only context I had of drinkable fiber was watching my dad try to force down another very popular brand in warm water every morning with great distress. What a pleasant surprise to have a fiber option as tasty and smooth as this SoWell one! The Apple Cinnamon flavor was also an unexpected delight - not overpowering at all, just a pinch of sweetness and hint of an Autumn drink! It dissolves completely - I thought I would have to use an electric hand mixer, but just using the shaker bottle got all the powder dissolved. It’s not thick or clumpy by any means.
The biggest improvement I have seen while using this fiber is actually regulating my appetite - which tends to get a bit off cadence while being in the office. Drinking the fiber once I get to my desk helps keep me satiated longer so I am not snacking before lunch.
