A well-functioning immune system is the foundation of long-term health in dogs and cats. Animals recovering from illness, undergoing chemotherapy, managing chronic infections, or simply aging benefit from targeted nutritional support that helps modulate and sustain immune response. Rx Vitamins Liquid Immuno delivers a concentrated combination of immune-supportive nutrients in a palatable liquid that integrates easily into a daily feeding routine.
Liquid Immuno is built around a core of beta-glucans, vitamin C, and proprietary botanical extracts shown to support innate immune function. Beta-glucans — polysaccharides derived from yeast cell walls — interact with macrophage and natural killer cell receptors to prime the immune system for faster pathogen recognition and response. Vitamin C acts as a cofactor in collagen synthesis and supports antioxidant defences during immune activation. The liquid format allows these nutrients to be absorbed quickly and dosed precisely by body weight.
Available in two flavour options — Bacon and Chicken — to accommodate the preferences of picky pets. The 60 ml and 120 ml sizes allow you to choose based on the duration of support needed and the size of your pet. The product requires no mixing or preparation and can be added directly to wet or dry food.
Rx Vitamins Liquid Immuno is manufactured as part of the Rx Vitamins veterinary supplement line by MedVant, available through professional channels in Canada.

Key Ingredients
Beta-glucans (yeast-derived) — immunomodulatory polysaccharides that activate macrophages and NK cells. Vitamin C (ascorbic acid) — antioxidant and cofactor in collagen synthesis. Proprietary botanical blend — supports immune cell function.
Directions for Use
Dose by body weight as directed by your veterinarian. Add directly to food at each meal or administer orally by syringe. Shake well before each use. Refrigerate after opening.
Supplement Advisor's Note
Liquid immune supplements are particularly useful during the recovery phase following illness or surgery, when oral intake may be limited and IV nutrition is no longer an option. The liquid format ensures that even animals with reduced appetite receive the full dose without the guesswork of powder mixing. Beta-glucans are one of the more well-studied immunomodulatory agents in veterinary medicine — their mechanism is specific enough to meaningfully support immune surveillance without the risks of non-selective immune stimulation.
Frequently Asked Questions
- Is Liquid Immuno suitable for both dogs and cats?
- Yes. The formula is appropriate for both species, with dosing adjusted by body weight.
- Should I use this long-term or only when my pet is sick?
- Both approaches are used. Some pets with chronic immune challenges benefit from ongoing maintenance dosing; others use it short-term during illness or recovery.
- Does it need to be refrigerated?
- Yes, refrigerate after opening to maintain potency and freshness.
- Can it be given alongside antibiotics or chemotherapy?
- Consult your veterinarian. In many oncology cases, immune support products are recommended alongside treatment; however, individual protocols vary.
- What is the difference between the Bacon and Chicken flavours?
- The active ingredient formula is identical. The only difference is flavouring — choose based on your pet's preference.
