Overcoming the Challenges of Probiotic Stability
Probiotics have long been recognized for their health benefits, particularly in maintaining gut microbiota balance and supporting digestive health. However, their effectiveness largely depends on their ability to survive external environmental stressors such as heat, moisture, stomach acid, and bile salts before reaching the intestines. Traditional probiotics often suffer from low viability, leading to diminished clinical efficacy.
To address this, ILDONG Bioscience has developed an advanced quadruple-coating technology, Q-Shield®, designed to significantly enhance the stability and functionality of probiotics. Recent clinical studies have validated the superior performance of quadruple-coated probiotics, demonstrating their effectiveness in gut health improvement, competitive exclusion of harmful bacteria, and enhanced intestinal adhesion.
The Science Behind Quadruple-Coating Technology
The Q-Shield® quadruple-coating method involves four layers of protective materials, each serving a crucial function:
Outer Protective Layer – Shields probiotics from heat and moisture during storage.
Acid-Resistant Layer – Protects against harsh stomach acid, ensuring probiotics survive the gastric environment.
Bile-Resistant Layer – Enhances resistance to bile salts, allowing probiotics to reach the intestines intact.
Adhesion-Promoting Layer – Improves intestinal adherence, ensuring prolonged colonization and beneficial interactions with gut microbiota.
This multi-layered coating system drastically enhances probiotic survival rates compared to uncoated or single-layer-coated probiotics, leading to greater bioavailability and improved clinical outcomes.
Clinically-Proven Gut Health Benefits
1. Enhanced Survival and Colonization
A 2022 study on quadruple-coated probiotics confirmed their significantly higher adhesion to intestinal epithelial cells, with up to 10.8 times improved adherence compared to uncoated strains. This increased adhesion allows probiotics to establish themselves in the gut more effectively, leading to longer-lasting health benefits.
2. Competitive Exclusion of Harmful Bacteria
The study further demonstrated that quadruple-coated probiotics exhibited 4.3 times stronger competitive exclusion against Salmonella Typhimurium, a common gut pathogen. This suggests that these probiotics not only colonize effectively but also prevent harmful bacteria from thriving, thereby maintaining a healthier gut microbiome.
3. Clinical Efficacy in IBS Patients
A randomized, double-blind, placebo-controlled clinical trial on ILDONG Bioscience’s Lacticaseibacillus rhamnosus IDCC 3201 highlighted significant improvements in irritable bowel syndrome with constipation (IBS-C). Participants who consumed the quadruple-coated probiotic for 8 weeks experienced:
Reduced abdominal pain and bloating
Improved stool frequency and consistency
Increased levels of beneficial bacteria, such as Akkermansia muciniphila
Additionally, untargeted metabolomic analysis indicated that specific metabolites linked to gut health, such as N-acetylornithine and 3-phenylpropionic acid, were significantly increased, further validating the probiotic’s role in modulating gut microbiota composition and metabolism.
4. Probiotic Diversity and Sex-Specific Benefits
Another clinical study on gQlab, a quadruple-coated multi-strain probiotic product, demonstrated significant improvements in IBS symptoms, particularly in female participants and constipation-predominant IBS patients. The study confirmed an increase in key probiotic strains, such as:
Lactobacillus plantarum
Lactobacillus acidophilus
Bifidobacterium longum
This suggests that quadruple-coated probiotics can enhance microbiome diversity, making them particularly beneficial for individuals with disrupted gut microbiota balance.
Why Q-Shield® is a Game-Changer in Probiotics
ILDONG Bioscience’s Q-Shield® technology is redefining probiotic efficacy, ensuring maximum survival, targeted intestinal delivery, and enhanced gut microbiota modulation. The clinical studies on quadruple-coated probiotics reinforce their superiority over conventional probiotics, making them a promising solution for addressing digestive health challenges.
