Zenka

Zenka comes in capsule form. It can be opened and mixed with food, or given whole directly into the mouth or placed in the bowl inside the capsule.

• Up to 40 lb (18 kg): 1 capsule per day
• Over 40 lbs: 2 capsules per day

Regularity is key: the effects are built up over time.

Zenka isn’t a sedative. Its strength lies not in acting within minutes, nor in causing the side effects of a tranquilizer. It’s an adaptogen: it helps the body gradually adapt to stress by naturally regulating the production of cortisol (the stress hormone).

For anxious or sensitive dogs, it’s recommended to administer Zenka for a period of 3 to 4 weeks for optimal results. While behavioural changes may not always be immediate, Zenka works in the body from the very first doses: it helps lower cortisol levels, which supports the nervous system, the immune system, and overall health.

Studies on ashwagandha show a stabilization of its effects over time: a reduction in biological markers of stress and an improvement in emotional and cognitive well-being after a few weeks of regular use. Generally, a dog gradually becomes calmer, more relaxed, and better able to adapt to their environment.

Zenka is licensed by Health Canada (NN.H6N1) . It has been approved to maintain calmness during periods of stress, support the proper functioning of the nervous system, promote balanced behaviour, and soothe animals exposed to external stressors. These effects have been scientifically demonstrated.

Zenka is formulated with organic ashwagandha, an adaptogenic herb known to help the body better manage stress. Studies have shown a reduction in cortisol in dogs subjected to stressful situations, with improvements in emotional well-being, social behaviour, and cognitive abilities, even in older dogs (Biswas et al., 2022; Cooley et al., 2024).

In other words, even if you don't see an immediate visible change, Zenka works from within the body: it helps lower cortisol, supports the nervous system, and contributes to better overall balance. The effects build gradually, with improvements in calmness, recovery, and general well-being.

But anxiety doesn't have just one cause: for the best results, look at the animal as a whole (environment, diet, health, emotional history). Zenka becomes an important ally, even more effective when integrated into a comprehensive approach, with the help, if needed, of a dog trainer, veterinarian, or nutritionist.

Every dog ​​is unique, but one thing remains true: when you support the body in the right way, it always ends up regaining its balance.

That's a very good thing. It shows that you're already looking to help your dog in a gentler, more respectful way. But not all natural products are created equal.

Zenka is a unique formula based on organic ashwagandha, developed with rigorous scientific methodology and approved by Health Canada (NN.H6N1). This approval confirms its calming effect during periods of stress, its support for the nervous system, its contribution to balanced behaviour, and its ability to soothe the body in the face of external stressors.

Recent studies demonstrate its effectiveness: a decrease in salivary cortisol in dogs under stress (Biswas et al., 2022, Journal of Veterinary Behavior). In older dogs, it improves emotional and cognitive well-being, reduces irritability, and enhances social interaction after 21 days, without side effects (Cooley et al., 2024, Frontiers in Veterinary Science).

In other words, Zenka acts on both visible behaviour and the physiological response (cortisol). This comprehensive approach is what makes the difference. Zenka is not just a "natural product"; it's a precise, scientifically validated tool designed for real and lasting support.

It's never too late to help a dog feel better. Zenka works gently, regardless of age or anxiety level, based on scientifically validated data.

Zenka is licensed by Health Canada (NN.H6N1):

• to maintain calm during periods of stress.
• to support the proper functioning of the nervous system.
• to promote balanced behaviour.
• to soothe animals exposed to external stressors.

These effects are supported in particular by:

• Biswas et al., 2022: significant reduction of salivary cortisol in dogs under stress, very good tolerance.
• Cooley et al., 2024: in older dogs, improved emotional and cognitive well-being, decreased irritability and better social interaction, with no reported side effects.

In short: even if visible improvement takes longer in very anxious or older dogs, Zenka works biologically by supporting nervous system balance, recovery, and emotional stability. It helps the body gradually regain a lasting state of calm.
