Mitochondria, MitoQ & Midlife Energy: Dr. Siobhan Mitchell of MitoQ

In Episode 175 of the Fit Mother Project Podcast, Dr. A talks with neuroscientist and MitoQ Chief Science Officer Dr. Siobhan Mitchell about one of the most powerful — and overlooked — drivers of women’s health after 40: mitochondrial function. She shares how her grandmother’s Alzheimer’s diagnosis inspired her career and why the latest science points to mitochondria, oxidative stress, and “inflammaging” as core players in memory, energy, and healthy aging.

You’ll learn how exercise, smart intervals, fasting, MCT oils, CoQ10, vitamin C, and mitochondrial-targeted antioxidants like MitoQ can help your cells produce cleaner energy, recover faster, and better protect your brain, heart, and muscles. Dr. Mitchell also breaks down what human studies actually show about MitoQ and other mitochondrial supports like PQQ, NAC, and NAD boosters.

If you’re a busy mom or midlife woman who wants steady energy, clearer thinking, and stronger training results without burning out your system, this conversation will give you a science-backed roadmap.

Key Takeaways

• Mitochondria = powerhouses and “CEOs” of the cell
• Oxidative stress & “inflammaging” drive faster aging
• Balance matters: not too much, not too little mitochondrial activity
• Exercise (especially intervals) trains mitochondrial resilience
• Fasting & ketones trigger autophagy and longevity pathways
• MCTs (especially C8/C10) support ketones and brain function
• CoQ10 is essential but poorly delivered into mitochondria via standard supplements
• MitoQ = mitochondria-targeted CoQ10 derivative with human data
• Studies: better power output, recovery, and less exercise-induced DNA damage
• Vitamin C, magnesium, B12 often need supplement support with age
• NAC, PQQ, NAD boosters, and urolithin A: promising but mixed data
• No magic bullets: stack smart supplements on top of fundamentals
