Most people think fatigue, muscle loss, and brain fog are just part of aging, but these changes often reflect a deeper issue happening inside your cells. Declining mitochondrial function may be one of the main drivers behind reduced energy, slower recovery, and long-term health decline.
In this episode of Extend, I sit down with Dr. Anurag Singh, Chief Medical Officer at Timeline, to unpack the science behind urolithin A and how mitochondrial health impacts muscle, brain, and immune function. We explore how the gut microbiome influences this process, why most people don’t produce enough urolithin A naturally, and what clinical research shows about improving cellular function.
We break down how mitophagy works, why mitochondrial quality declines with age, and how this affects strength, endurance, cognition, and immune resilience. We also explore how supplementation, combined with strategies like creatine, magnesium, vitamin D, and NAD precursors, can support long-term performance and recovery.
✅ We also discuss:
➡️ What mitochondria actually do and why they matter.
➡️ Why most people don’t produce urolithin A naturally.
➡️ Mitophagy and cellular cleanup with aging.
➡️ Muscle strength, endurance, and recovery.
➡️ Brain health and cognitive performance.
➡️ Immune function and inflammation.
➡️ Clinical trial results across different populations.
➡️ How to think about dosing and supplementation.
➡️ Synergies with creatine, magnesium, and vitamin D.
➡️ NAD, NR, and NMN for mitochondrial support.

Personally, for Urolithin A, instead of paying $100 month on another supplement, I make a simple, delicious, highly nutritious dessert. Recipe: Grass only Whole milk, soaked chia seeds in milk, splash of pomegranate juice, vanilla extract, splash of balsamic vinegar, then toppers. On top, put walnuts, strawberries, and or raspberries. So, my microbiome is making Urolithin A/B/C/D, and it tastes good. I only eat/rotate nutrient dense meals designed for a healthy body and have phased out foods designed to get me to mindlessly eat or buy (no nutrition and detrimental to my health). Bye bye big food companies...

The claims regarding brain health, cancer, the speculation about Japan, and his statements on Parkinson’s are all much thinner on evidence than his confident tone suggests. And the bottom-line issue remains: the man is selling exactly what he’s pitching
