Inulin and FOS are found in many foods, but are especially concentrated in chicory root, which is about 20% inulin and 10% FOS. Structurally, inulin is a long-chain molecule while FOS is a short-chain molecule. Both are soluble fibers with prebiotic properties that can enhance multiple measures of digestive health and overall well-being.

Performance Lab® Prebiotic’s Inulin-FOS Microflora Support
Inulin-FOS is noted for its resilience: It passes undigested through the stomach and small intestine, arriving intact in the colon.
In the colon, Inulin-FOS selectively feeds Bifidobacterium probiotic strains, stimulating their growth and proliferation.
A robust intestinal microbiome of Bifidobacterium (and other strains) is important for digestive and metabolic health because probiotics supply enzymes that enable the efficient breakdown and utilization of foods in the gut. This bioactivity accounts for probiotics’ most well-known benefits for digestive regularity, comfort and overall healthy function.
Why Performance Lab® Prebiotic Targets Bifidobacterium Probiotic Species:
  1. Bifidobacterium is suggested to more easily adhere to and reinforce the intestinal lining;
  2. Bifidobacterium are considered a highly competitive probiotic strain, possibly due to enhanced energy-scavenging capacity from a wider variety of nutrients;
  3. Bifidobacterium’s superior metabolic performance may outcompete bad bacteria in the gut more efficiently than other probiotic species
Beyond digestive health, Performance Lab® Prebiotic’s Bifidobacterium-promoting activity helps contribute to other beneficial activities associated with a healthy gut microbiome, including:
Pathogen resistance
Bifidobacterium fermentation of Inulin-FOS produces lactic acid that reduces gut pH, acidifying the colon to limit growth and activity of bad bacteria and pathogens, such as Candida albacans and E. coli. Bifidobacterium also adheres to the intestinal lining, helping to strengthen a critical barrier against pathogens and microbes.
Immune function
Probiotics’ anti-pathogen bioactivities contribute to their association with robust immune system health. Probiotics may also support healthy immune performance by enhancing the synthesis and proliferation of immune cells lymphocytes and macrophages, which play important roles in overall immune system function.
Nutritional status
In addition to creating an unfavorable environment for pathogens, Bifidobacterium and other lactic-acid producing flora promote a favorable acidic environment for absorption of minerals including calcium, magnesium, iron and zinc. Bifidobacterium also synthesizes B-vitamins and vitamin K in the gut.
Microbiome-gut-brain axis
Emerging research suggests probiotics may modulate stress, anxiety and mood by optimizing the microbiome-gut-brain axis, also known as the gut-brain connection.
The Bifidobacterium strain of probiotics nourished by Performance Lab® Prebiotic has been shown in animal research to increase tryptophan, a precursor to serotonin: A brain chemical with calming, mood-enhancing activities.
Studies have suggested the Inulin-FOS may support weight control by reducing food intake, which researchers attributed to Inulin-FOS’s suppression of the hunger hormone ghrelin and promotion of the satisfaction hormone peptide YY:

Performance Lab® Prebiotic’s Inulin-FOS Soluble Fiber Support
As a soluble fiber, Inulin-FOS cannot be digested in the small intestine. Instead, during digestion soluble fiber absorbs water, expanding and forming a gel as it passes through the GI tract. This biological activity accounts for many of soluble fiber’s benefits, including its support for:
Digestive health
  1. Inulin-FOS’s solubility adds bulk to stools while making them softer, helping to promote easier, more comfortable elimination;
  2. Soluble fiber can help ease issues with loose or watery stools, absorbing excess fluid to help form firmer stools and more regular elimination;
  3. Bulkier stools also help with constipation and related straining, which contribute to hemorrhoids and colon health concerns
Weight control
  1. Inulin-FOS’s ability to absorb water and swell in the stomach blocks the “hunger hormone” ghrelin and promotes feelings of satiety that help with appetite control;
  2. Influencing the caloric density of foods (when taken with food and water), functionally reducing the calorie content of any food item that is consumed;
  3. Balancing blood sugar: Inulin-FOS has no impact on blood sugar and slows food transit time in the gut, for a more gradual rise in post-meal blood sugar and a reduced glycemic load;
  4. Countering triglycerides. Taking inulin lowers triglycerides, the building blocks of fatty tissues associated with weight gain
Heart health
Soluble fiber from foods such as Inulin-FOS promote heart health by helping to maintain cholesterol levels that are already in normal range. In the gut, soluble fiber binds cholesterol from foods with bile, thereby limiting cholesterol absorption and encouraging cholesterol elimination. Strong evidence backing this bioactivity has earned soluble fiber a rare FDA qualified heart health claim:
“As part of a diet low in saturated fat and cholesterol, soluble fiber may reduce the risk of heart disease. A serving of Performance Lab® Prebiotic contributes 1.7 grams of soluble fiber to the 7 grams necessary per day to have this effect.”

Why Take Performance Lab® Prebiotic instead of a probiotic supplement?
Probiotic supplements may help to support healthy intestinal flora, but may also have limitations and side effects that influence their efficacy.
Performance Lab® Prebiotic takes a different approach to microflora health that may offer several advantages over standard probiotic supplements:
Probiotic Supplements Performance Lab® Prebiotic Advantage
Deliver multiple new probiotic strains to the gut’s existing microflora colony. Some bombard the gut with 10+ probiotic strains in unnatural ratios that may yield unpredictable or uncomfortable results Designed to fertilize the gut’s unique existing microflora colony, helping to promote robust, organic probiotic growth in a gentle, harmonious manner for superior activity, tolerability and efficacy
Must arrive alive in the colon to confer digestive benefits, but are easily destroyed by heat, cold, light and stomach acids Resilient, Orafti® Synergy1 inulin-FOS fiber passes through the stomach acids unharmed and is fermented by Bifidobacterium in the colon
Some products’ labels claim up to 2+billion “live” cultures, but are shown on analysis to have far fewer, with significant percentages as “dead on arrival” Always 100% bioactive and supplying the exact nutrition that is listed on the label, Performance Lab® Prebiotic arrives ready to support digestive health
Take Performance Lab® Prebiotic to nourish your
gut’s microflora and unlock the digestive and
whole-body health benefits associated with
probiotic balance.

Is Performance Lab® Prebiotic safe?
Like all Performance Lab® supplements, Performance Lab® Prebiotic is designed to be safe for long-term daily use, without the need for cycling. Performance Lab® Prebiotic achieves this by using pure, potent ingredients that are dosed appropriately and in line with clinical research. Performance Lab® Prebiotic’s clean formula design – free of GMOs, gluten, soy, colorants, preservatives and other additives – is also well-tolerated by the body; safe and beneficial for long-term use.
How is Performance Lab Prebiotic better than a supplement that has 1+ Billion live cultures of 10+ probiotic strains?
Supplements that supply multiple strains of live active cultures in high numbers have many variables that make it hard to predict efficacy and outcomes. More probiotic strains are not necessarily better, and may be associated with undesirable side effects like gas and bloating. High numbers of live active cultures look appealing on a label, but due to the fragility of probiotics and less-than-optimal manufacturing practices of some brands, the actual number of live cultures that reach the colon may be far less.
Performance Lab® Prebiotic takes a different approach: instead of flooding the digestive system with as many different probiotic strains in the highest quantities possible, Performance Lab® Prebiotic selectively nourishes a single superior strain that already exists in the gut: Bifidobacterium.
Supplying the ideal nourishment for Bifidobacterium, Performance Lab® Prebiotic encourages robust probiotic growth that works in harmony with your unique gut environment – helping to support all the benefits of probiotics more comfortably, organically and reliably than some probiotic supplements.
