Strong Choice
This is a thoughtfully formulated calming supplement that targets both the nervous system and the gut–brain axis using a combination of amino acids, herbs, magnesium, and a defined probiotic strain. It’s suitable for dogs and cats of any size when used alongside a complete and balanced diet. As with any supplement, individual response can vary, and it’s best used as one part of an overall stress-management plan rather than a stand-alone solution for more serious anxiety issues.

Strengths
- Multi-modal formula using GABA, L-theanine, L-tryptophan, and L-tyrosine to support neurotransmitter balance involved in relaxation and mood regulation.
- Includes several well-known calming botanicals (passion flower, valerian root, ashwagandha) at defined amounts, plus magnesium, which can support neuromuscular relaxation.
- Contains a specific probiotic strain (Lactobacillus paracasei LPC-37) at a clearly stated level of 3 billion CFU to support the gut–brain axis and digestive health.
- Powder format with chicken bone broth base makes it easier to mix with food, which can improve acceptance for many pets.
Considerations
- Contains chicken bone broth, so it is not appropriate for pets with confirmed chicken allergies or strict elimination diets.
- Herbal blends like valerian, passion flower, ginger, and ashwagandha may not be suitable for every pet, especially those on multiple medications or with liver disease, so veterinary guidance is recommended in those cases.
- This is a supplement, not a complete diet, so it should only be used in addition to a balanced dog or cat food rather than as a primary nutrition source.
- Calming supplements can vary in effectiveness between individuals; pets with significant anxiety or behavior concerns may still need a full behavior plan and veterinary/behaviorist support.

Top 5 Ingredients Explained
01
GABA
GABA (gamma‑aminobutyric acid) is an inhibitory neurotransmitter sometimes included in pet supplements or calming diets to help support relaxation and reduce stress‑related behaviors in dogs and cats, though it is not an essential nutrient or typical food ingredient. Oral GABA may have modest calming effects but has limited ability to cross the blood–brain barrier, evidence in companion animals is mixed, and owners should consult a veterinarian before use due to potential interactions with sedative or anticonvulsant medications and dosing considerations.
02
L-Tyrosine
L‑Tyrosine is a conditionally essential amino acid added to pet foods and supplements as a targeted amino acid source and precursor for neurotransmitters (dopamine, norepinephrine), thyroid hormones and pigment synthesis, supporting cognitive function and stress responses in dogs and cats. It is not a replacement for complete protein and should be used under veterinary guidance—particularly in animals with thyroid disease or on certain medications—since high supplemental doses can cause gastrointestinal upset or potential drug interactions.
03
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.
04
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.
05
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.
