Verified Jun 4, 2026
A soft chew calming supplement for dogs that uses a blend of botanicals, amino acids, and a postbiotic to help support relaxation and emotional balance. Key active ingredients include magnolia bark, ashwagandha, chamomile, passion flower, L-theanine, L-tryptophan, and a heat-treated probiotic blend, delivered in a chicken and bacon-flavored chew. It’s designed for daily or as-needed use alongside a complete and balanced dog food.
This is a thoughtfully formulated calming supplement for dogs that combines several well-known calming botanicals and amino acids with a postbiotic blend for gut–brain support. The active ingredients are clearly identified with specific amounts, which is helpful for assessing what your dog is getting in each chew. It can be a reasonable option for dogs who need a gentle, non-sedating calming aid used together with a balanced diet and appropriate behavior support.

KibbleLab Review
Strengths
- Multiple recognized calming ingredients (magnolia bark, ashwagandha, chamomile, passion flower, L-theanine, L-tryptophan) included at specified amounts, which adds transparency about dosing.
- Includes a postbiotic blend (heat-treated Lactobacillus rhamnosus and Bifidobacterium longum) aimed at supporting the gut–brain axis and mental wellbeing.
- Palatable base with chicken bone broth, bacon fat, and salmon oil, which most dogs find tasty, making daily administration easier.
- Uses safe, common preservatives (citric acid, mixed tocopherols, rosemary extract) rather than artificial colors or flavors.
Considerations
- This is a supplement, not a complete diet, so it must be fed alongside a fully balanced dog food and not as a primary source of nutrition.
- Contains chicken (chicken bone broth) and fish (salmon oil), which may not be suitable for dogs with known chicken or fish allergies.
- Botanical and amino acid calming ingredients can affect dogs differently; some dogs may show more benefit than others, and very sensitive dogs should be monitored when starting any new calming product.
- Because it’s designed for long-term or regular use, it’s a good idea to check with your veterinarian, especially if your dog is on other medications or has chronic health conditions.

Top 5 Ingredients Explained
01
Magnolia
Magnolia (typically used as magnolia bark or standardized extracts) is included in some pet products as a botanical supplement for its bioactive compounds, such as magnolol and honokiol, which have antioxidant, anti-inflammatory and calming (anxiolytic) properties rather than serving as a nutrient source. It provides functional—not nutritional—benefits and has limited research in dogs and cats, so pet owners should consult a veterinarian because it can cause gastrointestinal upset, may interact with medications (including sedatives and drugs metabolized by liver enzymes), and is generally avoided in pregnant or nursing animals.
02
Ashwagandha
Ashwagandha is an herbal adaptogen sometimes added to pet foods and supplements to support stress resilience, calming, and general wellness via bioactive withanolides rather than as a macronutrient. Some studies and anecdotal reports suggest potential calming and anti-inflammatory benefits for dogs and cats, but evidence is limited, dosing is not well standardized, and owners should consult their veterinarian because it can cause gastrointestinal upset, interact with sedatives, thyroid or immune-modulating drugs, and is generally avoided in pregnant animals.
03
Chamomile
Chamomile is an herbal botanical commonly used in pet supplements, treats and topical preparations as a mild calming, anti‑inflammatory and digestive aid rather than a primary nutrient source, with flavonoids and terpenoids that can help soothe gastrointestinal upset, skin irritation and mild anxiety in dogs and cats. It is generally safe in small, properly formulated amounts but can trigger allergic reactions in animals sensitive to the Asteraceae family, may interact with blood‑thinning medications, and concentrated essential oils or extracts should be avoided without veterinary guidance.
04
Passiflora Incarnata
Passiflora incarnata (passionflower) is a botanical ingredient used in pet supplements and calming treats for its mild sedative and anxiolytic properties rather than as a nutrient; it contains flavonoids and alkaloids that are thought to influence nervous system activity in dogs and cats. While it may help reduce mild anxiety or promote relaxation, evidence in pets is limited and it should be used cautiously—avoid combining with other central nervous system depressants, and consult your veterinarian before use in pregnant or nursing animals or pets on medications due to potential interactions and dosing concerns.
05
L-Theanine
L‑Theanine is a naturally occurring amino acid commonly added to pet foods and supplements as a calming/functional ingredient to help reduce stress and promote relaxation without sedation. It has shown promise in dogs (and to a lesser extent cats) for easing situational anxiety and improving calmness, but effects can vary, proper dosing is important, and owners should consult their veterinarian—especially if the pet is on medications or has health conditions—because it is an adjunct to, not a replacement for, behavioral training or medical treatment.
