Mitochondria Expert Reveals: Why Your Immune System Starts Failing in Your 40s (And How to Fix It)

80% of all autoimmune diseases occur in women, and no one can explain why. Cancer cells are always present in your body, but it's only when your T cells go into energy deficit that cancer starts overtaking the system. And here's what almost no one is talking about: the mitochondria in your immune cells are the reason MS, chronic fatigue, neurodegeneration, and even cancer progression happen when they happen.

In this episode, I sit down with Dr. Anurag Singh, MD, PhD immunologist and Chief Medical Officer of Timeline who spent 20 years studying mitochondria and screened 4000 compounds from pomegranates to discover one molecule that changes cellular aging. We break down immunometabolism, the emerging field linking immune health and metabolism, why your T regulatory cells are the CEOs of your immune system, how mitochondrial dysfunction in immune cells triggers autoimmune conditions, and why rejuvenating mitochondria can get your immune system in check to defeat cancer. We also cover NAD+ (and why NMN and NR supplements don't work the way people think), the creatine sweet spot for muscle quality (500mg-1g, not the 5g everyone's taking), why Parkinson's is linked to paraquat, a mitochondrial toxin used in fertilizers and dry cleaning and how AI is fast-tracking the discovery of next-generation molecules for neurodegeneration. This conversation completely shifted how I think about immune health, brain protection, and what's actually driving the diseases we fear most.
