KibbleLab Score
7.4 out of 10

Overall, this is a thoughtfully formulated calming supplement for cats that uses several well-known ingredients targeted at stress and mild anxiety. The combination of B1 (thiamine), ginger, chamomile, L‑theanine, and L‑tryptophan provides multiple pathways to support relaxation and may also help with stress-related tummy upset. It’s best suited for otherwise healthy cats who need a little extra help coping with events like travel, visitors, vet visits, or household changes.

Nutritional Perspective

KibbleLab Review

Strengths

  • Multiple calming ingredients (L‑theanine, L‑tryptophan, chamomile, thiamine) that are commonly used in veterinary behavior support products.
  • Includes ginger, which can be helpful for queasy stomachs in some cats, especially when stress and GI upset go together.
  • Powder format that mixes with food, which is often easier for cats than giving tablets or capsules.
  • Chicken-based flavoring can improve palatability for many cats, making it more likely they’ll accept it in their food.

Considerations

  • This is a supplement, not a complete and balanced diet, so it should only be used alongside a nutritionally complete cat food.
  • Contains chicken-based flavor and brewers yeast, which may not be appropriate for cats with chicken allergies or yeast sensitivities.
  • Calming supplements can support relaxation but usually work best in combination with behavior modification and environmental management, especially for more severe anxiety.

Top 5 Ingredients Explained

01
Thiamine
Thiamine (vitamin B1) is a water‑soluble vitamin commonly added to dog and cat foods to support carbohydrate metabolism and normal nervous and cardiovascular function. Because animals store little thiamine and it can be degraded by heat or destroyed by thiaminase in some raw fish, consistent dietary supply is essential—deficiency causes anorexia, lethargy, neurological signs and, in severe cases, seizures, so commercial diets are carefully fortified to meet species requirements.
02
Ginger
Ginger is commonly added to pet foods and treats as a natural flavoring and functional ingredient to support digestion and reduce mild nausea, with active compounds like gingerols providing modest anti-inflammatory and antioxidant effects. It can be beneficial for dogs (and occasionally cats) with motion sickness or stomach upset when used in small amounts, but high doses should be avoided and caution is advised for pets on anticoagulant medications, pregnant animals, or those with known sensitivities due to potential effects on clotting and occasional gastrointestinal irritation.
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
L-Tryptophan
L‑Tryptophan is an essential amino acid used in pet foods to meet amino acid needs and, when supplemented, to support production of neurotransmitters such as serotonin and melatonin. It is important for protein synthesis and may help with mood, sleep, or mild anxiety in some dogs and cats, but supplemental doses should be used under veterinary guidance since diet usually supplies adequate amounts and improperly manufactured supplements have on rare occasions caused adverse effects.
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.
