Free Shipping

Main Highlights

Dont be fooled! Not all fiber pills and capsules are the same. Many fiber supplements on the market contain cheap, non-organic, insoluble bulking fibers. Peak Performance USDA Organic Prebiotic Fiber is an all plant-based soluble fiber supplement that blends with water in the gut, and can help speed the passage of food and waste through your gut to help prevent leaky gut as well as other health benefits. Great for men and women.
3-in-1 Organic Prebiotic Fiber Pill - Our capsule supplement is a soluble combination of what we believe are the 3 best dietary fibers, including: Inulin (Jerusalem Artichoke), Acacia Fiber, and SunFiber (Guar Seed) that helps the intestinal gut flora microbiome to flourish, and in turn produces the short-chain fatty acids that nourish the cells lining the colon. Great for digestive and intestinal health without feeling bloated, stuffed or heartburn.
Natural vs Synthetic: Synthetic vitamins and supplements are not as bioavailable, not absorbable / usable and not recognizable to the body as naturally derived supplements. Mounting studies show natural supplements have adaptogenic benefits. All of our ingredients are carefully chosen and 3rd party tested for purity.
Vegan Formulated & Allergy Free - Free Of Soy, Milk, Egg, Shellfish, Corn, Wheat & Peanuts. Contains NO Gluten or Preservatives. Manufactured Under The Highest Quality FDA, GMP & NSF Regulations and USA Standards.
