VFCore BIO — Postbiotic Gut & Immune Supplement for Dogs & Cats

For decades, "probiotic" has been the default term for gut health supplementation — live bacteria meant to colonise the gut and improve digestion. The problem is that most live probiotics fail before they ever reach the intestine. Stomach acid, bile, and digestive enzymes destroy a large fraction of the bacterial dose, and what survives often doesn't establish a stable population. Postbiotics solve this problem completely.

A postbiotic is the inactivated form of a beneficial bacteria — the bacterial cell, its components, and its bioactive metabolites — that retains the immune-stimulating and gut-balancing benefits of the live organism without needing to survive digestion. Postbiotics also offer better stability, longer shelf life, and consistent dosing, making them the next generation of gut health supplementation.

VFCore BIO is built around HK L-137™ — the gold-standard postbiotic produced by House Wellness Foods Corporation, Japan. HK L-137 is heat-killed Lactobacillus plantarum L-137, a strain extensively researched for its ability to enhance immunity, reduce gastrointestinal inflammation, promote gut balance, and demonstrate superior heat stability and shelf life. The mechanism is elegant: HK L-137 binds to M cells in the gut-associated lymphoid tissue and stimulates production of crucial immune cytokines including IL-12 and IFN-Beta. Comparative studies show HK L-137 stimulates IL-12 production to a greater extent than BCG, Bifidobacterium longum, Lactobacillus casei, Bifidobacterium bifidum, Lactobacillus acidophilus, or Lactobacillus delbrueckii.

In a canine clinical study on acute or intermittent diarrhoea (double-blind placebo-controlled efficacy study), the HK L-137 treatment group showed significantly better fecal scores than placebo at every measured time point (P<0.05), and significantly lower pathogenic bacterial loads of Clostridium perfringens and Enterococcus faecium (P<0.05). In feline trials, HK L-137 improved diarrhoea outcomes in 72% of cases.

VFCore BIO doesn't stop at HK L-137. The formula layers in four additional gut and immune ingredients to deliver complete coverage:

Nano-Chitooligosaccharide 145mg is the smallest subunit of chitosan, processed for nano-scale absorbability. It provides anti-inflammatory and antioxidant action and aids gastrointestinal balance — particularly valuable in inflammatory bowel disease (IBD) and chronic enteritis.

Yang® 100mg is a synergistic dual-yeast complex from Saccharomyces cerevisiae and Cyberlindnera jadinii. The specific genome and physical structure activates immune receptors (Dectin-1, MBR, TLR2) more efficiently than standard yeast derivatives, delivering up to 3× stronger immune support than standard beta-glucans alone.

Agrimos® MOS 50mg delivers beta-glucan and mannan-oligosaccharide — yeast cell wall components that boost immunity and physically trap harmful gut pathogens (binding their fimbriae so they can't adhere to gut walls).

FOS / Fructooligosaccharide 100mg is a true prebiotic — selectively feeding beneficial gut bacteria (Bifidobacteria, Lactobacilli), increasing intestinal absorption, reducing constipation and soft stool, exerting immunostimulant effects, and promoting healthy stool formation. FOS works synergistically with HK L-137 to create a gut environment that favours beneficial flora.

Vitamin B2 1mg + Vitamin B6 1mg support metabolic recovery and nervous system function — both impacted by prolonged GI disease.

The lickable tuna-with-salmon paste base ensures consistent voluntary intake even in unwell pets. GI conditions often come with reduced appetite, and the format is engineered to be accepted when dry powders, capsules, and tablets are refused.

VFCore BIO is appropriate for acute diarrhoea from infection, dietary indiscretion, stress, or diet change; chronic diarrhoea and IBD; enteritis and gut inflammation; immune support post-vaccination, post-illness, or in immunocompromised pets; and post-antibiotic recovery to rebuild beneficial gut bacteria lost during antibiotic therapy.

Pair with VFCore SK if skin issues are gut-driven (atopic dermatitis often has gut dysbiosis), or with VFCore Feline Vitality for cats requiring full daily nutrient coverage during recovery.

Daily Feeding Guide

Standard Dosage: 1 sachet per 5 kg body weight per day

For promotion of immune system in pets. Or as recommended by your veterinarian.

Recommended use periods:

• Acute diarrhoea: full dose during episode + 5–7 days after recovery
• Chronic diarrhoea / IBD: ongoing daily use
• Post-antibiotic recovery: 2–4 weeks following antibiotic course
• Immune support: ongoing daily during high-stress periods (vaccination, boarding, weather change)

How to give: Tear sachet, squeeze paste directly into the mouth, onto a clean plate, finger, or mix with food. The tuna-salmon paste base is highly palatable.

Storage Guidelines

• Store in a cool, dry place below 25°C
• Keep away from direct sunlight and moisture
• Postbiotic is heat-stable but extreme heat should still be avoided
• Do not refrigerate unopened sachets
• Once opened, use immediately — do not store partial sachets
• Keep out of reach of children
• Check expiry date before use
• Tamper-evident sachet — do not use if seal is broken or damaged
