Advanced gut-health support.

Our premium Prebiotic formula is made using research-backed Inulin-FOS from chicory root. Produced to the highest quality clean label standards. To deliver gut health benefits like no other Prebiotic supplement.

Orafti® Synergy1 Inulin-FOS.

Inulin and FOS are soluble fibers with prebiotic properties. Structurally, inulin is a long-chain molecule while FOS is short-chain. Both are found in chicory root, which is 20% inulin and 10% FOS.

Inulin-FOS is resilient: It passes undigested through the GI tract, arriving intact in the colon where it selectively feeds Bifidobacterium probiotic strains and stimulates their growth.

Performance Lab® Prebiotic Inulin-FOS fiber has been shown in human research to shift Bifidobacteria distribution in the gut from 20% to 71%

Why Prebiotic selectively nourishes Bifidobacterium

  • Bifidobacterium is suggested to more easily adhere to and reinforce the intestinal lining;
  • Bifidobacterium is a highly competitive probiotic strain, possibly due to enhanced energy-scavenging capacity from a wider variety of nutrients;
  • Bifidobacterium's superior metabolic performance may outcompete bad bacteria in the gut more efficiently than other probiotic species.

By stimulating robust growth of indigenous Bifidobacterium rather than introducing multiple new probiotic strains, Performance Lab® Prebiotic promotes more organic, comfortable and reliable digestive support.

2-in-1 prebiotic support.

Together in Prebiotic Orafti® Synergy1, inulin + FOS optimize two key pathways that unlock multiple bio-performance benefits:

Prebiotic takes a different approach to microflora health that may offer several advantages over standard probiotic supplements:

  • checkmark icon Some products' labels claim up to 2+billion 'live' cultures, but are shown on analysis to have far fewer. With many cultures 'dead on arrival'.
