VetriScience's Max Veterinary Strength Calm and Confident chews step up from the brand's standard Composure line with a formula built around lemon balm extract, L-theanine and thiamine, aimed at supporting brain function in both cats and dogs, and its 4.2 star average across 201 reviews suggests a positive but still developing track record.
Owners of dogs with more persistent or intense stress responses who want a higher potency option from an established supplement brand, especially if a standard-strength chew hasn't been enough.

Overview
["This 45 count package is VetriScience's Max Veterinary Strength version of its Calm and Confident line, built around lemon balm extract, L-theanine and thiamine, with the brand describing it as supporting brain function in both cats and dogs rather than just easing situational stress.", "As a step-up formula, it's positioned for pets that need more support than a standard calming chew, though specific per-chew ingredient amounts aren't detailed in this listing, so owners should check the packaging or reach out to VetriScience directly for exact dosing.", 'At $49.43, this is the most expensive product in this roundup, reflecting its positioning as a max strength, veterinary grade option. With 201 reviews and a 4.2 star average, plus roughly 500 units bought in the past month, it has a smaller but positive track record so far.']

Performance notes
Lemon balm extract and L-theanine are both associated with calming, relaxed states, and thiamine (vitamin B1) is a common addition across this category for nervous system support. As a max strength formula, this is likely a higher concentration version of ingredients found in VetriScience's standard Composure chews, though exact amounts aren't published here.
What buyers say
With 201 reviews at a 4.2 star average and an estimated 500 units bought in the past month, this max strength option has a smaller but positive following, consistent with a premium step-up product rather than an entry-level best seller.
