Fiber Prebiotic Complete RS (Formerly PaleoFiber RS)

Resistant Starch and Fiber Blend for Gut and Heart Health*
Powdered formula with resistant starch fiber to promote healthy GI function by supporting microbial balance, short-chain fatty acid production, and intestinal barrier integrity.*
Provides 10 g per serving of a proprietary resistant starch/fiber blend, containing 4 g of total resistant starch and 5 g dietary fiber.
• Supports healthy gut motility*
• Helps promote colonic health*
• Supports proper intestinal permeability*
• Provides support for microbial balance*
• Promotes healthy glucose metabolism*
Recommended Use: Take 10 grams (approximately one scoop) per day or as
directed by your health‑care practitioner. Best if mixed into liquid using a blender or shaker bottle. Can also be mixed into food, such as yogurt or gluten‑free cereal. Due to the nature of resistant starch, consider starting with a smaller dose and gradually increasing to a full serving depending on your tolerance.
Features two forms of resistant starch: organic green banana flour and organic potato starch powder
Resistant starch acts like a fiber because it resists digestion, as enzymes in the gastrointestinal (GI) tract are inactive against it. Once RS reaches the large intestine, it is fermented into short‑chain fatty acids (SCFAs), which serve as a fuel for both beneficial bacteria and cells of the GI tract. SCFAs have been shown to influence GI cellular health, cellular metabolism and signaling, and cardiovascular health.*

What This Product Is
Fiber Prebiotic Complete offers a unique blend of beneficial fiber sources from various fruits, vegetables, roots, seeds, and tree extracts, providing 8 grams of dietary fiber per serving. Many Americans fall short of the recommended daily fiber intake, which can lead to digestive discomfort, such as occasional constipation or diarrhea. Unlike many fiber supplements, this product is free from grain-based fibers (such as wheat, oat, and rice bran) and legume-based fibers (such as peas, beans, and soy), making it a great option for individuals with specific dietary sensitivities.*
Getting enough fiber supports digestive health by promoting bowel regularity and the growth of beneficial gut bacteria to help maintain a healthy gut microbiome. Additionally, the benefits go beyond digestion — fiber also plays a supportive role in healthy blood sugar and fat metabolism, normal appetite, and potentially healthy body composition.*
Mechanism of Action
Synergistic Soluble and Insoluble Fiber Blend
The diverse blend of fibrous ingredients provides both soluble and insoluble fibers. Soluble fiber dissolves in water to form a gel-like substance that promotes overall intestinal health, helps maintain normal appetite, and supports occasional diarrhea. Insoluble fiber does not dissolve in water, helping add bulk to stool and support healthy bowel movements, supporting those with occasional constipation.*
Prebiotic Support with Acacia Gum and Inulin
Acacia gum and inulin serve as prebiotic fibers that help promote the growth of beneficial gut bacteria and overall digestive health. These prebiotics nourish the existing beneficial microbiome, supporting a healthy GI environment and optimal gut function.*
Metabolic and Body Composition Benefits
Beyond digestive support, the fiber blend plays a supportive role in healthy blood sugar and fat metabolism, normal appetite and satiety after meals, and potentially healthy body composition. Ingredients include acacia gum, vegetable fiber, guar gum, cranberry seed powder, carrot fiber, inulin, psyllium husk, flax seed, glucomannan (from konjac), and prune powder.*
Applications
- Individuals seeking comprehensive fiber supplementation with 8 g per serving*
- Those needing grain-free and legume-free fiber for dietary sensitivities*
- Individuals wanting prebiotic support for a healthy GI microbiome*
- Those seeking appetite and satiety support for body composition goals*
