The Science-Backed Bitter Compound That Mimics GLP-1 (No Injections Needed!)

The Science-Backed Bitter Compound That Mimics GLP-1 (No Injections Needed!)

Author: Dr. Kara Fitzgerald August 5, 2025 Duration: 53:06
I’ve been watching the science behind Calocurb evolve over the last year, and I have to say—this is one of the most exciting clinical tools I’ve seen emerge in the metabolic space in quite some time. A hops-derived compound that stimulates endogenous GLP-1, CCK, and PYY—without a prescription or injection? That’s a big deal, especially for patients struggling with appetite regulation, weight plateaus, or the aftermath of GLP-1 discontinuation.

In this episode, I sit down with Sarah Kennedy, founder of New Zealand-based Calocurb, to talk about the years of government-funded research that led to this discovery, the remarkable clinical outcomes they’ve seen so far, and how I’ve personally used it in my practice with excellent results. If you’re looking for science-backed, natural strategies to support appetite control, fasting, or GLP-1 transitions—this one’s worth a listen. ~DrKF
