Prebiotic Bifido Boost Powder (XOS): Comfortable Digestion, Balanced Microbiome and Sustained Immunity – Advanced Supplement For Daily Intestinal Health

Prebiotic Bifido Boost Powder (XOS), Now Foods contains Xylooligosaccharides (XOS) 1.55 g from PreticX™ Prebiotic Complex, a next-generation prebiotic, created to selectively nourish beneficial intestinal bacteria – especially Bifidobacteria. Unlike traditional fibers, XOS are short carbohydrates, resistant to digestion in the small intestine, which reach the colon, where they are fermented in a targeted manner toward "friendly" species. The result: digestive comfort, balanced transit, increased production of short-chain fatty acids (SCFA) with protective role, support for intestinal mucosal integrity and a valuable contribution to body immunity. The PreticX™-based formula stands out through purity, good solubility and superior digestive tolerance, suitable for daily use to maintain a harmonized microbiome.

As the modern diet becomes poorer in prebiotic fibers, the microbiome loses its diversity and stability, which can lead to abdominal discomfort, unpredictable transit, food sensitivities and reduced defense capacity at the intestinal barrier level. XOS contributes to restoring the intestinal ecosystem balance, providing "preferential food" for desired bacteria and limiting the expansion of opportunistic species. Benefits are felt not only at the digestive level, but also systemically, through the gut-immunity-metabolism axis.

Detailed Benefits of Xylooligosaccharides (XOS)

• Selective stimulation of Bifidobacteria – foundation of a resilient microbiome

Bifidobacteria are considered a "quality indicator" of a healthy microbiome. XOS acts in a targeted manner, promoting the growth of these friendly species, with impact on overall microbial balance. A microbiome dominated by beneficial bacteria means:
- Less "unfriendly" fermentation and disturbing gas
- Efficient fiber metabolism and optimal SCFA synthesis
- Stronger intestinal barrier and balanced immune response

Through XOS supplementation:
✅ Abundance of Bifidobacteria and other useful bacteria increases
✅ Risk of intestinal dysbiosis decreases
✅ Long-term microbiome stability is supported

• Digestive comfort and regular transit

Flora imbalances can generate bloating, heavy sensation and unpredictable transit. XOS contributes to normalizing motility and forming an optimal fecal bolus, without irritating the mucosa.
✅ Supports regularity without aggressive laxative effect
✅ Reduces post-prandial discomfort and bloating sensation
✅ Promotes calmer and more predictable digestion

• SCFA production (acetate, propionate, butyrate) and mucosal protection

XOS fermentation by beneficial bacteria generates short-chain fatty acids – essential fuel for colon cells and regulator of local pH. A lower pH in the colon limits opportunistic microorganism proliferation and supports a favorable environment for "good species."

✅ Increases butyrate production – energy for enterocytes and local anti-inflammatory support
✅ Maintains mucosal integrity and barrier function
✅ Contributes to a stable and protective intestinal ecosystem

• Sustained immunity through healthy intestinal barrier

Approximately 70% of immune cells are located in the digestive tract. XOS helps maintain tight junctions between epithelial cells, supporting an efficient selective barrier and educated immune response.

✅ Supports optimal functioning of GALT (gut-associated lymphoid tissue)
✅ Contributes to reducing mucosal irritation and to a balanced inflammatory profile
✅ Promotes oral tolerance and adequate immune reactivity

• Balanced metabolism and weight management

Through effects on the microbiome and SCFA production, XOS influences metabolic homeostasis: better insulin sensitivity, efficient energy substrate utilization and appetite control.

✅ Supports appetite regulation through metabolic signals derived from SCFA
✅ Contributes to glycemic balance in the context of an adequate diet
✅ Promotes a healthier body composition long-term

• Superior digestive tolerance and FODMAP-friendly profile

Compared to some prebiotic fibers that can produce discomfort (e.g., high doses of inulin), XOS are well tolerated at usual amounts, having more predictable fermentation and lower bloating risk for most users.

✅ "Gentle" prebiotic, suitable for daily use
✅ Targeted fermentation, with fewer unwanted effects
✅ Suitable option for those seeking comfort and efficiency

• Mineral absorption and bone health

SCFA resulting from XOS fermentation can improve mineral bioavailability (such as calcium and magnesium) by lowering colonic pH and facilitating their transport.

✅ Supports mineral absorption in the dietary context
✅ Indirectly contributes to bone health
✅ Optimizes essential nutrient utilization

• Gut-brain-skin axis: systemic well-being

The microbiome constantly communicates with the nervous system and skin through metabolites, microbial neurotransmitters and immune responses. Balancing flora with XOS can have positive echoes on mental tone and skin quality.

✅ Promotes general well-being by reducing digestive discomfort
✅ Contributes to a more tempered systemic inflammatory response
✅ Supports balance of functional organism-microbiome axes

• Synergy with probiotics and dietary compatibility

XOS functions as preferred food for probiotics (especially Bifidobacteria), transforming the product into an ideal partner for probiotic formulas or for diets rich in live cultures (yogurt, kefir).

✅ Potentiates probiotic colonization and activity
✅ Helps maintain effects even between probiotic courses
✅ Easily integrates into daily nutritional routine

• Harmonized intestinal ecosystem – basis of robust health

A coherent microbiome means more efficient digestion, sustained immunity and balanced metabolism. Through selective nourishment of beneficial species, XOS supports a virtuous circle: more "good" bacteria → more protective SCFA → stronger barrier → digestive comfort and systemic balance.

✅ Selective nourishment of friendly flora
✅ Daily intestinal comfort and predictable transit
✅ Support for immunity, metabolism and general well-being

Prebiotic Bifido Boost Powder (XOS), Now Foods offers a modern prebiotic solution, built on microbiome science, for those who want a calm gut, balanced transit and sustained immunity. With XOS 1.55 g from PreticX™, the product provides exactly what beneficial bacteria prefer, in a well-tolerated format that's easy to integrate into daily routine – a simple step toward harmonious digestion and a more resilient body.
