MedVant Advanced CALM Calming Liquid for Dogs & Cats

Natural Calm for Dogs and Cats — Without Drowsiness

Anxiety in companion animals is more common than most pet owners realize. Separation distress, noise phobias, veterinary-related fear, car anxiety, and reactions to household changes are among the most frequently cited reasons for veterinary behavioural consultations in Canada. The conventional response — pharmaceutical anxiolytics — can be effective in severe cases, but many pets need something that reduces reactivity without altering personality, causing sedation, or creating dependency.

Advanced CALM by MedVant is a highly palatable liquid formula that supports a calm temperament without drowsiness. It is authorized as a Veterinary Health Product by Health Canada (NN.V0R5), suitable for both short-term situational use (before stressors) and long-term daily support in chronically anxious pets. MedVant is a Canadian company based in Woodstock, Ontario, that specializes in evidence-based veterinary nutraceuticals formulated to minimize filler and maximize active ingredients.

Key Ingredients

• Colostrum Fraction: A specific bioactive fraction of bovine colostrum with demonstrated anxiolytic properties. The active components within this fraction interact with GABA receptors in the brain — the same receptor system targeted by benzodiazepines — but do so in a modulatory, non-sedating way. Unlike benzodiazepines, the colostrum fraction does not suppress consciousness or cause dependency.
• L-Theanine (as Suntheanine®): The patented, clinically validated form of L-theanine — an amino acid found naturally in green tea. Suntheanine is supported by research showing increased alpha brain wave activity (the "relaxed alertness" state) and reduced beta brain waves (associated with arousal and excitement). Studies specifically support its efficacy in reducing separation anxiety and environmental stress in dogs and cats.
• Thiamine (Vitamin B1): A B-vitamin essential for healthy neurological function. Thiamine deficiency in animals can manifest as nervous system dysfunction and heightened stress reactivity; supplementation supports baseline neurological calm.
• Lecithin: A phospholipid that supports neuronal membrane integrity and acetylcholine synthesis — both important for a well-regulated nervous system response.

How to Use

Shake well before each use. For maximum palatability, store at room temperature — even after opening.

• Short-term (situational): Give the appropriate dose one hour before the stressful event
• Long-term (ongoing): Give the appropriate dose twice daily

Do not use in immature, pregnant, or lactating animals. Store at 15–25°C out of direct sunlight. To avoid contamination, pour without touching the bottle opening to another surface.

Supplement Advisor's Note

What distinguishes Advanced CALM from many calming supplements is the colostrum fraction's mechanism: it acts on GABA pathways — the same biological target as prescription anxiolytics — but without the receptor downregulation and dependency risk associated with benzodiazepine drugs. The Suntheanine brand of L-theanine is also significant: it's the research-grade form used in the published studies, not a generic L-theanine. For pets with moderate anxiety that hasn't responded adequately to single-ingredient supplements, the multi-mechanism approach here (GABA modulation via colostrum, alpha wave promotion via theanine, and neurological baseline support via B1) often produces better results. For maximum effect, begin the twice-daily protocol 3–5 days before a known high-stress event rather than starting on the day itself.
