Arc-1 vs Klarity Health
The verdict
Klarity Health takes it — 58.1/100 to 56.3/100, but only just.
Klarity Health grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. Klarity Health is a telehealth marketplace connecting patients to independent licensed providers for medical weight loss, including GLP-1 medications like semaglutide, tirzepatide, Wegovy, Zepbound,… Arc-1 is close behind and may still be the better fit — see the factor split below.
