Welcome to Vitamin Z

Hi there!

I created Vitamin Z to share my research on health and wellness, longevity and healthy aging, and ways to optimize cognitive, physical and emotional health.

My journey began when my late father, a cardiologist, was diagnosed with a brain tumor at a young age. Frustrated by the conventional healthcare system, I dove deep into the world of biomedical science.

I have interviewed hundreds of doctors and health system leaders to help my clients spot trends and opportunities in healthcare. I am an advisor to Noom, a digital health company helping millions live better longer, and a project leader at GLG, where I advise global business leaders on healthcare innovation.

My philosophy combines traditional western medicine with alternative approaches to health and wellness. I’ve worked with health leaders in China, India and Japan to get insights on Eastern practices like mindfulness, yoga, ayurveda. I’ve advised global healthcare leaders on how technology can transform healthcare using mobile health and digital therapeutics, diagnostics, telehealth and virtual care, medical data & analytics, and smart medical devices.
