Our read

An exact tie: the veterinary-strength Composure Pro posts the same score as the standard Composure on every dimension. Pro layers L-tryptophan and more thiamine onto the same Suntheanine L-theanine, but our rubric scores both on that L-theanine, which sits below the studied dose either way, so the upgrade buys no rubric gain. Per-day cost is nearly identical because Pro doses half a chew for a small dog. In our view, the standard version is the value pick.

This verdict is our opinion under the PetScored rubric, not veterinary advice. The exact sub-scores are in the table below; each product’s source confidence and limitations stay on its own scorecard.

Composure Calming Chews

A calming chew scored on its disclosed L-theanine (the studied Suntheanine form); the C3 colostrum complex is not in our evidence library and at 21 mg the L-theanine is below the studied dose, so it lands Mixed.

Composure Pro

The veterinary-strength Composure, scored like the regular version on its disclosed Suntheanine L-theanine, with added L-tryptophan and a higher thiamine load; at 25 mg the L-theanine is still below the studied dose and the C3 colostrum complex is not in our evidence library, so despite the clinical-onset marketing it lands Mixed, the same band as the standard Composure.

Comparison scores use the same reconstructed score-event math as the supplement scorecards. Source confidence, unresolved gaps, evidence-library citations, and dose caveats remain attached to each individual scorecard.
