Herbsmith Microflora Plus Digestive Support Supplement for Cats (4 Pack)

Microflora Plus goes far beyond a standard probiotic. This 4-in-1 synbiotic formula pairs probiotics, prebiotics, digestive enzymes, and gut-soothing herbs to help restore balance to your cat's microbiome - the ecosystem that drives digestion, nutrient absorption, immune health, and everyday vitality. Powerful enough to help during digestive upset; gentle enough for daily use. Vet-developed by Dr. Chris Bessent. NASC approved. Capsule format for protected delivery.

The Case for a Complete Gut Formula

Loose stool, gas, vomiting after meals, and occasional GI upset are signs that the gut microbiome is out of balance. That community of trillions of gut bacteria influences far more than digestion - it drives nutrient absorption, skin health, immune function, and systemic inflammation. A probiotic alone only replenishes bacteria; it does not feed them (prebiotics), help break down food before bacteria ever see it (enzymes), or soothe the gut lining during recovery (herbs). Microflora Plus delivers all four layers in a single capsule, making it the most comprehensive approach to feline gut health available in a single product.

When to Use Microflora Plus For Cats

  • Healthy stool and regular digestion: Supports normal bowel movements and helps maintain firm, consistent stool, especially during digestive upset.
  • Sensitive stomachs and vomiting after meals: Digestive enzymes and soothing herbs help cats who experience occasional vomiting, gurgly stomach, or discomfort after eating.
  • Post-antibiotic gut support: Replenishes beneficial bacteria to help restore balance after antibiotics, GI illness, or stress-related digestive changes.
  • Food transitions and finicky eaters: Helps stabilize digestion when switching foods; ideal for picky or sensitive cats.
  • Gas, bloating, and smelly stool: Balances gut flora to reduce odor, discomfort, and excess gas.
  • Immune and skin support: Because most immune function lives in the gut, supporting the microbiome helps maintain healthy skin and seasonal comfort.

Active Ingredients and Their Actions

Per two capsules (guaranteed analysis):

Probiotics - 10 Billion CFU (Bacillus and Lactobacillus blend):

  • Bacillus subtilis and Bacillus licheniformis (soil-based/spore-forming): Spore-forming bacteria that survive passage through stomach acid and reach the intestine intact - a critical advantage over fragile strains that degrade before doing any good. Soil-based Bacillus strains colonize the gut transiently but persistently during daily use, crowding out pathogenic bacteria, producing natural antimicrobial compounds (bacteriocins), and actively rebalancing the microbial community. Bacillus subtilis also produces enzymes that assist in digestion directly.
  • Lactobacillus acidophilus: One of the most well-researched probiotic strains in veterinary medicine; colonizes the small intestine, produces lactic acid to lower intestinal pH and inhibit pathogenic bacteria, and supports the integrity of the gut mucosal lining. Particularly helpful for post-antibiotic recovery and food-transition diarrhea.

Prebiotics:

  • FOS (Fructooligosaccharides) - 100 mg: A soluble prebiotic fiber that selectively feeds beneficial Lactobacillus and Bifidobacterium species in the colon while being indigestible to pathogenic bacteria. FOS fermentation by gut bacteria produces short-chain fatty acids (SCFAs), particularly butyrate, which is the primary energy source for colonocytes (colon cells) and a key regulator of gut mucosal integrity and immune function. Prebiotics are what make the probiotic strains establish and thrive - without a prebiotic, even high-CFU probiotics have reduced efficacy.

Digestive Enzymes (per two capsules):

  • Protease - 5,625 HUT/g: Breaks down proteins into amino acids. Cats are obligate carnivores with high protein requirements; efficient protein digestion is critical for nutrient absorption and reducing the fermentation of undigested protein in the colon (a driver of gas and foul-smelling stool).
  • Amylase - 3,750 SKB/g: Breaks down starches and carbohydrates into sugars. Cats have limited endogenous amylase production; supplemental amylase helps process the starches found in commercial cat foods more completely.
  • Lipase - 750 FIP/g: Breaks down fats and oils into glycerol and fatty acids for absorption. Supports fat-soluble vitamin absorption alongside fat digestion.
  • Cellulase - 600 CU/g: Breaks down plant cell walls (cellulose), releasing nutrients from plant-based food components that cats cannot digest on their own.
  • Bromelain - 22.5 GDU/g (from pineapple stem): A proteolytic enzyme from pineapple with additional anti-inflammatory activity in the gut mucosa, beyond protein digestion alone.
  • Papain - 3.75 TU/mg (from papaya): A proteolytic enzyme from papaya that complements protease and bromelain to provide broad-spectrum protein breakdown across a range of pH levels in the GI tract.

Enzyme activity units explained: SKB = starch dextrinization rate; HUT = protein hydrolysis from hemoglobin; FIP = fatty acid liberation from olive oil; CU = cellulose hydrolysis rate; GDU = tyrosine liberation from casein (bromelain); TU = tyrosine liberation from casein (papain).

Gut-Soothing Herbs - 270 mg (Cinnamon, Ginger, Licorice blend):

  • Gui Zhi (Cinnamon Bark - Cinnamomum cassia): Warms the middle burner (Spleen and Stomach in TCVM), supports healthy gut motility, and has documented antimicrobial activity against gut pathogens. Cinnamaldehyde constituents inhibit pathogenic bacteria while sparing beneficial strains - a selective antimicrobial effect that supports microbiome rebalancing.
  • Sheng Jiang (Ginger Root - Zingiber officinale): One of the most important digestive herbs in both TCVM and Western botanical medicine. Ginger supports gastric emptying, reduces nausea and vomiting, stimulates digestive enzyme secretion, and has documented anti-inflammatory and carminative (gas-reducing) activity in the GI tract. Gingerol and shogaol constituents have extensively documented anti-nausea and prokinetic mechanisms - directly addressing the vomiting and gurgly stomach patterns that drive cat owners to seek gut support.
  • Gan Cao (Licorice Root - Glycyrrhiza uralensis): Soothes and protects the gut mucosal lining, reduces intestinal inflammation, and harmonizes the actions of the other herbs. Glycyrrhizin and glycyrrhetinic acid constituents have documented mucosal-protective and anti-inflammatory activity in the GI tract, supporting gut lining integrity during and after digestive upset.

Why Capsule Format Matters

Probiotics are live microorganisms in a dormant state. As soon as they contact moisture - even humidity in the air - they activate and begin consuming their own food supply, reducing potency rapidly. Each Microflora Plus capsule is individually sealed in a blister pack to prevent moisture exposure until the moment of use. Once opened and mixed with food, activated bacteria have a limited lifespan; the sealed format ensures that the full CFU count is still viable at the time of administration. This is why the format is capsule and blister-packed rather than a powder jar or soft chew - it protects potency in a way that bulk powder formats cannot.

How to Feed

Pop the recommended capsule out of the foil only when ready to administer. Options for serving:

  • Slip the whole capsule onto food or into a treat
  • Open the capsule and sprinkle the powder over their regular meal
  • Open the capsule and mix the powder into bone broth, wet food, canned pumpkin, or a small amount of yogurt

Daily consistency is key. Beneficial bacteria do not persist indefinitely - daily replenishment keeps the microbiome balanced. Even after symptoms resolve, ongoing daily use supports long-term digestive resilience, immune health, and overall wellbeing.

Directions for Use

Cats (all weights): 1 capsule daily, or as directed by your veterinarian

Kittens under 6 months: 1/2 capsule daily, or as directed by your veterinarian
Kittens over 6 months: Follow adult cat dosing, or as directed by your veterinarian
Consult a veterinarian for kittens under 12 weeks.

Cautions

For animal use only. This product is intended for intermittent or supplemental feeding only. Safe use in pregnant animals or animals intended for breeding has not been proven. If the animal's condition worsens or does not improve, stop product administration and consult your veterinarian.

Frequently Asked Questions

Does Microflora Plus need to be refrigerated?

No refrigeration required, though it will not harm the product. Keep capsules in their blister pack and only remove the daily dose when ready to administer. The sealed blister format protects the live bacteria from moisture and air exposure, which is what maintains potency without refrigeration, or as directed by your veterinarian.

Why does Microflora Plus come in capsule form instead of powder?

Probiotics are live microorganisms in a dormant state. Once they contact moisture - even humidity from the air - they activate and begin consuming their food supply, quickly reducing potency. Individual blister-sealed capsules prevent moisture contact until the moment of use, ensuring the full CFU count is still viable at administration. Bulk powder jars cannot maintain the same protection. The capsule format is what makes the potency claim reliable, or as directed by your veterinarian.

What do the enzyme activity abbreviations (SKB, HUT, FIP, etc.) mean?

These are standardized units of enzyme activity - they measure how much work a given amount of enzyme can do, not just how much enzyme is present by weight. SKB measures starch breakdown rate (amylase); HUT measures protein hydrolysis rate (protease); FIP measures fat liberation rate (lipase); CU measures cellulose breakdown rate (cellulase); GDU and TU measure protein digestion by bromelain and papain, respectively. The practical takeaway: amylase breaks down starches and carbohydrates, protease breaks down proteins into amino acids, lipase breaks down fats, and cellulase breaks down plant fiber. All six enzymes are calibrated for carnivore digestion - the enzyme profile reflects what cats actually need, or as directed by your veterinarian.

How is Microflora Plus different from a standard probiotic supplement?

Most probiotics deliver one thing: bacteria. Microflora Plus delivers four: probiotics to replenish beneficial bacteria, prebiotics (FOS) to feed and establish those bacteria in the gut, digestive enzymes to improve nutrient breakdown upstream of where bacteria work, and soothing herbs (cinnamon, ginger, licorice) to calm the gut lining during recovery. The soil-based Bacillus strains also provide a colonization advantage over standard dairy-derived strains, which are more fragile and shorter-lived in the gut environment. The result is more comprehensive, more durable gut support than a single-strain or multi-strain probiotic alone, or as directed by your veterinarian.
