In this episode with Mazen Karnaby, founder of Zenos Health, you'll hear how a pharmacist who spent 17 years filling prescriptions behind the counter ended up building one of the more rigorously formulated supplement lines on the market. You'll hear his full story, including a melanoma diagnosis that reframed his entire approach to health, get into the formulation details behind his most talked about products, from the creatine gummies people get genuinely addicted to, to UriZen for kidney and urinary tract support, VZen for the vaginal microbiome, and BeautyZen for skin and hair, and hear about Zenos Alive and the Zenos Health Summit, a new wellness festival and conference coming to Riyadh, Saudi Arabia in 2027.
Mazen Karnaby is a US trained pharmacist and the founder of Zenos Health. After a melanoma diagnosis several years ago, his focus shifted from reactive care toward prevention and long term resilience. He co-owns Cedra Pharmacy locations across California, Texas, and New York, and built Zenos Health around science backed formulations designed to take the guesswork out of supplementation.
