LONGEVITY with Nathalie Niddam

Today, I'm joined by Dr. Taz Bhatia, a trailblazing integrative medicine physician, entrepreneur, and leading voice in women's health and longevity. In our conversation, Dr. Taz opens up about how her personal health challenges as a conventionally-trained MD led her to explore nutrition, Chinese medicine, and Ayurveda, inspiring her to reimagine what it means to truly care for the whole person.

We also dive into the work of Countdown, a nonprofit accelerating mitochondrial science and medicine to improve how we prevent and treat disease. If you’re interested in women’s health, functional medicine, healthy aging, and cellular energy, this episode is packed with valuable insights.
