Your Mitochondria Are Running the Show! (They’re not Just the “Powerhouse”)
Tracy’s Take
By Tracy Kanaczet
The mitochondria are not just the “powerhouse of the cell” like we learned in grade school.
They are essential to life and the foundation of health. They are a biological age clock and a center of cellular aging.
I’ve always been interested in the mitochondria. I have a master’s in exercise physiology and love the science of metabolism.
Fascinating Facts About Mitochondria
Each cell has thousands of mitochondria in them, but it depends on the energy demand of the tissue.
🥚 Ovaries (egg cells) have the most—about 100,000–600,000 mitochondria per cell
🧠 Cardiac muscle cells and neurons come next, with thousands per cell
🩸 Red blood cells have zero mitochondria because they need to carry oxygen throughout the body. They rely on glycolysis to function, which does not occur inside mitochondria
👉Did you know mitochondria have their own DNA? Crazy right?
We get our mitochondrial DNA from our mother, not our father!
A nucleus contains about 20,000 genes, but mitochondrial DNA only has 37 genes.
Mitochondria and Cell Death (Apoptosis)
It is up to the mitochondria to initiate cell death, called apoptosis.
They release cytochrome c, and once it crosses the mitochondrial membrane, there is no going back, the cell is committed to death.
This is a normal and necessary process in the body to remove damaged cells and maintain healthy tissue function.
Free Radicals and Mitochondrial Damage
Free radicals don’t damage the cell as much as we often think, because we make enough antioxidants that help neutralize them.
But they can damage mitochondrial DNA.
If mitochondrial DNA cannot repair itself fast enough, the mitochondria become dysfunctional. When this happens, they lose their ability to produce energy efficiently and may undergo apoptosis.
If dysfunctional mitochondria do not undergo apoptosis, several things can happen:
They can accumulate more mutations and potentially become cancerous
They can impair organ function
They may release signals that attract immune cells or drive chronic inflammation, contributing to diseases such as arthritis, atherosclerosis, or neurodegenerative disorders
They can become senescent cells (“zombie cells”), contributing to aging and conditions like Alzheimer’s disease or fibrosis
How to Help Your Mitochondria
There are several tools being studied to support mitochondrial health:
Elamipretide – helps strengthen the mitochondrial membrane by binding to cardiolipin. The electron transport chain (where cellular energy is made) is in the inner membrane, so strengthening it may improve function (Use code TRACY15 for 15% off)
MOTS-c – a signaling peptide related to mitochondrial communication and metabolism
5-Amino-1MQ – studied for metabolic and cellular energy pathways
Ubiquinol (CoQ10 active form) – big helper in the electron transport chain
Spermadine- helps cells shift to ‘cleanup state’ enhancing autophagy (cell cleanup) and mitophagy (mitochondria cleanup).
Quality Peptides Source
I personally use and recommend Biolongevity Labs because they meet high standards:
GMP-certified U.S. facility
Tested by three independent labs
High-purity, U.S.-compounded peptides
Verified batches with Certificates of Analysis (COAs)
Out of all the peptide companies out there, this is the one I trust most. Use my referral code TRACY15, to receive 15% off of your order.

🩶 Tracy’s Takeaways
Mitochondria are more than the “powerhouse of the cell”—they are central to energy, aging, and overall health
Each cell contains thousands of mitochondria (ovaries have the most; red blood cells have none)
Mitochondria have their own DNA, inherited from your mother, with only 37 genes compared to nuclear DNA’s ~20,000+
They regulate programmed cell death (apoptosis) through cytochrome c release
Mitochondrial damage from oxidative stress can lead to dysfunction, inflammation, aging, and disease
Supporting mitochondrial health is a growing focus in longevity science, using tools like CoQ10 (ubiquinol), spermadine, and peptides such as MOTS-c and elamipretide
