Rx Vitamins Liquid NutriCalm Calming Liquid for Dogs & Cats, 120 ml

Herbal Calm in a Liquid Format — No Pilling Required

Some pets simply will not accept tablets or capsules — and that's where liquid supplements earn their place. Liquid NutriCalm by Rx Vitamins is a natural herbal calming formula designed specifically for dogs and cats who need stress support in the most accessible format possible: a liquid that can be mixed directly into food or given orally with a syringe. It's especially practical for cats and small dogs, where precise, small-volume dosing matters.

Rx Vitamins is a manufacturer with a strong reputation in the veterinary nutraceutical space — their formulas are developed by veterinarians, carry the NASC (National Animal Supplement Council) quality seal, and are formulated without unnecessary fillers or artificial flavours. Liquid NutriCalm is authorized as a Veterinary Health Product by Health Canada (NN.M2F8).

Key Ingredients

• L-Theanine: The primary anxiolytic amino acid in this formula, L-theanine promotes alpha brain wave activity (relaxed, calm alertness) without causing sedation or behavioural blunting. It works by modulating inhibitory neurotransmitters (GABA) without directly suppressing CNS function.
• Valerian Root Extract: A well-documented botanical anxiolytic with GABA-A agonist properties. Particularly effective for situational anxiety — travel, veterinary visits, grooming sessions, fireworks.
• Ashwagandha Extract: An adaptogenic root that helps normalize the stress response by regulating cortisol and supporting adrenal function during chronic or repeated stressors.

Directions for Use

Shake well before each use. Give orally twice daily or one hour before a stressful event.

• Cats and very small dogs (under 10 lbs): 1 ml twice daily
• Dogs 10–25 lbs: 2 ml twice daily
• Larger dogs: as directed by your veterinarian or per product label

Do not use in pregnant or lactating animals, or in immature animals. Do not give prior to anaesthesia or alongside CNS depressants. Not for use in animals with kidney, liver, or thyroid disease unless directed by a veterinarian. Store at 15–25°C out of direct sunlight.

Supplement Advisor's Note

Liquid NutriCalm and NutriCalm Suspension (the newer salmon-flavoured version) share the same core active ingredient profile. If your pet accepts both, the suspension may offer a palatability advantage due to the salmon flavour. Liquid NutriCalm remains the established formulation and is appropriate for pets who take supplements mixed into food without concern about flavour. Both are appropriate for daily use — unlike pharmaceutical anxiolytics, the herbal ingredients in this formula support healthy neurotransmitter function rather than suppressing it, making them safe for chronic use without dependency risk.
