Eating less?
Your gut still needs its fiber.
GLP-1 medications reduce how much you eat — and fiber intake often drops right along with it. Constipation is the most common GI side effect people report. Ageless Multi Fiber™ is designed to support digestive comfort during reduced-calorie eating, and help fill nutritional gaps when appetite is reduced.

You don't have to take our word for it.
Hear directly from people who added Ageless Multi Fiber™ to their routine, in their own words.
When your appetite changes,
fiber is often the first thing to go.
Fiber is already one of the most under-consumed nutrients in the average diet.
Most people fall short even eating normally.
When food intake drops, that gap widens fast, and resistant starch intake can fall to almost nothing. Your gut microbiome doesn't need less fiber just because you're eating less overall, it needs it consistently, scoop after scoop.
Americans don't get enough fiber to begin with.
Let alone on a GLP-1.

Frequently asked questions
Powered by clinically studied Solnul® resistant potato starch and supported by complementary fibers, Ageless Multi Fiber supports digestive health, regularity, gut microbiome balance, metabolic health, and healthy aging.
Rather than relying on a single fiber source, Ageless Multi Fiber delivers a diversified fiber system designed to support the body through multiple complementary mechanisms.
• Feeding beneficial gut bacteria
• Supporting healthy microbial balance
• Promoting digestive regularity
• Supporting healthy stool consistency
• Providing fermentable substrate for short-chain fatty acid (SCFA) production
• Supporting gut barrier function
• Helping promote satiety and fullness
• Helping fill widespread fiber and resistant starch gaps
Unlike many fiber products that focus on a single mechanism, Ageless Multi Fiber supports the entire gut health cascade—from prebiotic activity to postbiotic production to digestive regularity.
• Solnul® Resistant Potato Starch: A clinically studied type 2 resistant starch that acts as a prebiotic fiber. Solnul® has been shown to support beneficial bacteria such as Bifidobacterium and Akkermansia, healthy stool patterns, gut barrier function, nutrient absorption, and metabolic health.
• Partially Hydrolyzed Guar Gum (PHGG): A gentle, soluble, fermentable fiber that supports digestive comfort, regularity, and microbiome balance.
• Acacia Gum: A well-tolerated soluble prebiotic fiber that helps nourish beneficial bacteria while supporting digestive health.
• Oat Fiber: A predominantly insoluble fiber that supports stool bulk, intestinal transit, and healthy bowel function.
• FIBRISS® Organic Baobab Fruit Powder: Provides soluble fiber, insoluble fiber, and naturally occurring polyphenols that support microbiome diversity and digestive wellness.
• Citrus Pectin: A soluble, fermentable fiber that complements the microbiome-supporting benefits of the formula and contributes additional polyphenols.
Together, these ingredients provide a diversified fiber system designed to support digestive and overall health from multiple angles.
In clinical studies, participants consumed Solnul® resistant potato starch daily for four weeks, during which researchers observed significant improvements in beneficial gut bacteria and markers related to digestive and metabolic health. For best results, Ageless Multi Fiber should be taken consistently every day as part of a healthy diet and lifestyle.
• Adults 40+
• Individuals who consume relatively few fruits, vegetables, legumes, or whole grains
• People looking to support digestive regularity
• Individuals interested in supporting their gut microbiome
• Those seeking a diversified fiber supplement rather than a single-fiber product
• People looking to increase resistant starch intake
• Individuals using GLP-1 medications who may be consuming less dietary fiber as a result of reduced food intake
Because fiber needs vary from person to person, please consult your healthcare provider if you have specific medical concerns.
1) Fiber Diversity
Most fiber supplements rely on a single fiber source, such as psyllium husk. Ageless Multi Fiber combines:
• Soluble fiber
• Insoluble fiber
• Resistant starch
• Fermentable fibers
• Naturally occurring polyphenols
This allows the formula to support multiple aspects of digestive and gut health simultaneously.
2) Clinically Studied Resistant Starch
Ageless Multi Fiber includes 3.5 grams of Solnul® resistant potato starch, a clinically studied ingredient shown to support beneficial bacteria, healthy stool patterns, gut barrier function, and metabolic health.
3) Supports More Than Regularity
While many fiber products focus primarily on bowel movements, Ageless Multi Fiber was designed to support:
• Digestive health
• Microbiome diversity
• Gut barrier function
• Nutrient absorption
• Metabolic health
• Healthy aging
4) Gentle Daily Use
The formula includes well-tolerated fibers such as Solnul®, PHGG, and acacia gum, making it suitable for consistent daily use.
• Clinically studied Solnul® resistant potato starch
• Partially hydrolyzed guar gum (PHGG)
• Acacia gum
• Oat fiber
• Baobab fiber
• Citrus pectin
These fibers were selected not only for their benefits, but also for their digestive tolerance.
In clinical research, Solnul® resistant starch was shown to be well tolerated and did not increase reports of:
• Bloating
• Gas
• Abdominal discomfort
• Belching
• Nausea
That said, anytime fiber intake is increased, some individuals may experience temporary digestive changes as the gut microbiome adapts. For those who currently consume very little fiber, starting with a partial serving and gradually increasing to a full serving may help improve tolerance.
• Insoluble fibers help provide stool bulk.
• Soluble fibers help support digestive wellness and microbial balance.
• Resistant starch helps nourish beneficial gut bacteria and support healthy stool patterns.
Clinical research on Solnul® resistant starch demonstrated improvements in constipation-associated stool patterns, helping support more normal bowel function.
For best results, Ageless Multi Fiber should be used consistently and consumed with adequate fluid intake.
• Increased bowel activity
• Changes in stool frequency
• Mild gas
• Mild bloating during the adjustment period
These effects are typically temporary and often improve as the digestive system adapts. The fibers in Ageless Multi Fiber were selected in part because of their favorable digestive tolerance profile compared to many traditional fiber supplements.
Because fiber plays a critical role in digestive health, regularity, microbiome balance, satiety, and metabolic health, consuming less food can make an already significant fiber gap even larger. Ageless Multi Fiber was designed to help address this challenge by providing 6 grams of dietary fiber from a diversified blend of:
• Soluble fiber
• Insoluble fiber
• Resistant starch
• Naturally occurring polyphenols
This diversified approach supports multiple aspects of digestive and gut health rather than relying on a single type of fiber.
We do not recommend mixing Ageless Multi Fiber into hot beverages or foods that exceed approximately 140°F (60°C). Ageless Multi Fiber contains resistant starch, which is valued for its ability to resist digestion in the small intestine and reach the colon intact.
Exposure to high temperatures may alter the structure of resistant starch and reduce some of its unique prebiotic properties and benefits. For best results, mix Ageless Multi Fiber into cold or room-temperature beverages, smoothies, yogurt, or other cool foods.
• Gluten-free
• Vegan-friendly
• Non-GMO
These attributes make it suitable for a wide range of dietary preferences and lifestyles. Ageless Multi Fiber is both vegan- and vegetarian-friendly. It contains no animal-derived ingredients and is made with plant-based ingredients.
