Dr. Tamborlane

"As a clinician and clinical investigator concerned about better treatments for diabetes, the VIVI Cap will be of particular benefit for my patients who require insulin shots, as the vast majority of patients use insulin pens for their daily injections."

Dr. Diana Isaacs 

ADCES Diabetes Educator of the Year 2020

"Most people don't realize how fragile insulin is, and how to store it for it to work the most effectively. The VIVI Cap is an incredibly simple solution to ensure that insulin is safe to use and that none of it goes to waste"

Susan B. Sloane, CDE
