Frequently asked questions

What is Zero Crave Rx?

Zero Crave is a compounded medication that contains the active ingredients Bupropion, Naltrexone, and Methylcobalamin (Vitamin B12). This medication is designed to help with weight management and reduce food cravings.* This is considered an off-label medication for weight loss, and it is not FDA-approved.

How does Zero Crave Rx work?

Zero Crave contains Bupropion which is an antidepressant medication that has been shown to decrease appetite. Zero Crave also contains Naltrexone which is an opioid antagonist that may curb hunger and food cravings. Methylcobalamin (Vitamin B12) is added as a supplement since studies have linked low B12 levels to increased body fat and reduced metabolism. Altogether, people may find that their appetite is reduced and experience fewer food cravings.*
