Immunity Digestion Puppy Chews Supplement
Verified Jun 6, 2026
These soft chew supplements are designed for puppies over 6 months to support digestive function and developing immune defenses. They use yeast-derived prebiotics (MOS, FOS) and beta-glucans along with vitamins C and E to help promote healthy gut bacteria and immune support. The chews are meant to be given alongside a complete puppy diet, not as a primary food source.
This is a thoughtfully formulated supplement for puppies that focuses on gut and immune support using well-established ingredients like MOS, FOS, beta-glucans, and antioxidant vitamins. It’s most appropriate for otherwise healthy puppies over 6 months who may benefit from an added digestive or immune-supportive chew, used in addition to a complete and balanced puppy food. As with any supplement, it should be used in line with the recommended amounts and not as a replacement for veterinary care if your puppy has ongoing digestive issues.

At a Glance
KibbleLab Review
Strengths
- Targets digestive and immune support with MOS, FOS, and beta-1,3-glucans, which are commonly used to help nurture beneficial gut bacteria and immune function.
- Includes antioxidant vitamins C and E, which can help support normal immune defenses in growing puppies.
- Soft chew format can be easier to give than powders or capsules, especially for young dogs.
- Formulated for puppies over 6 months, a stage when many pups are transitioning diets and may be more prone to mild digestive upsets.
Considerations
- Contains dried chicken and wheat flour, which are common allergens, so it is not a good fit for puppies with known chicken or wheat allergies or sensitivities.
- This is a supplement, not a complete and balanced diet, so it must be given alongside an appropriate puppy food to meet your puppy’s full nutritional needs.
- Puppies under 6 months should not receive this product, so very young puppies or toy breeds started early may need a different approach.

Top 5 Ingredients Explained
01
MOS
MOS (mannan-oligosaccharides) are prebiotic fibers derived from yeast cell walls commonly added to dog and cat foods to support digestive health by encouraging beneficial gut bacteria and helping reduce adhesion of certain pathogens to the intestinal lining. They may improve stool quality and support immune function as a functional ingredient rather than a nutrient source; MOS is generally considered safe but effectiveness depends on dose and product quality, so consult your veterinarian for pets with specific gastrointestinal issues or special dietary needs.
02
Yeast Extract
Yeast extract is a concentrated, water‑soluble ingredient used primarily as a natural flavor enhancer and palatant in pet foods, while also supplying soluble proteins, free amino acids, nucleotides and B‑group vitamins. It can improve palatability and provide small supportive nutrients for metabolism and digestive/immune health, but may contain notable sodium and could be a concern for animals with yeast sensitivity or those on sodium‑restricted or renal prescription diets—consult your veterinarian if unsure.
03
Beta-1,3 Glucan
Beta-1,3 glucan is a functional, soluble fiber sourced from yeast, fungi, or grain husks and is added to pet foods and supplements primarily for immune support and gut health rather than as a macronutrient. It can help stimulate innate immune responses and modulate inflammation in dogs and cats, but effectiveness depends on source and dose, and pet owners should consult a veterinarian—especially for animals with autoimmune conditions or those on immunosuppressive drugs.
04
Yeast Extract
Yeast extract is a concentrated, water‑soluble ingredient used primarily as a natural flavor enhancer and palatant in pet foods, while also supplying soluble proteins, free amino acids, nucleotides and B‑group vitamins. It can improve palatability and provide small supportive nutrients for metabolism and digestive/immune health, but may contain notable sodium and could be a concern for animals with yeast sensitivity or those on sodium‑restricted or renal prescription diets—consult your veterinarian if unsure.
05
Zeolite
Zeolite is a naturally occurring microporous mineral (commonly clinoptilolite) used in pet products as an anti‑caking agent, carrier and adsorbent to help control odors, bind mycotoxins and heavy metals, and reduce ammonia in litter or feed; it is not a nutrient but can indirectly support gut/environmental hygiene rather than supply protein, vitamins, or calories. While some evidence suggests benefits such as improved fecal quality and reduced toxin exposure, zeolite can also adsorb minerals or medications at high inclusion rates, so only food‑grade sources at appropriate levels should be used and pet owners should consult their veterinarian before use.
