Ark Health vs Rivas Medical Weight Loss
The verdict
Ark Health takes it — 56.8/100 to 55.6/100, but only just.
Ark Health grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. Ark Health is a national direct-to-consumer telehealth platform with one of the widest menus in the directory — compounded semaglutide ($169/mo), tirzepatide ($249/mo) and oral semaglutide ($125/mo), plus… Rivas Medical Weight Loss is close behind and may still be the better fit — see the factor split below.
