The revelation that mitochondria are actually primary melatonin production sites flips our understanding of this molecule's function. We've been treating it as a centralized hormone signal from the pineal gland, when in reality it's a decentralized cellular mechanism—each mitochondrion producing melatonin to protect itself during the oxidative stress of energy production.
This changes the therapeutic calculus completely. If mitochondrial melatonin production declines with age or metabolic dysfunction, supplementation isn't just about sleep hygiene—it's about restoring a fundamental cellular defense mechanism. The Warburg reversal you describe (forcing cancer cells back to oxidative phosphorylation) suggests that low-dose melatonin might function as a metabolic reset button, particularly for tissues with high energy demands.
I'm curious about the implications for mitochondrial diseases and neurodegenerative conditions where ATP production is already compromised. If melatonin production is energy-dependent, these populations might be caught in a vicious cycle: damaged mitochondria produce less melatonin, which further reduces their ability to protect themselves from oxidative damage. Has any research explored exogenous melatonin as a mitochondrial support strategy in these conditions?
You hit the nail on the head with the "centralized vs. decentralized" framing. It’s a design flaw in the system: once the engine (mitochondria) starts failing, it stops producing its own coolant (melatonin), which causes it to overheat and fail faster.
That vicious cycle is real, and the paper actually touches on exactly what you're asking about.
It cites a study (Suofu et al.) showing that melatonin synthesis is tightly linked to mitochondrial activity, specifically in the brain. When that production drops due to aging or disease, the system essentially eats itself.
But the good news is that the "manual override" seems to work. The review notes that exogenous melatonin didn't just act as an antioxidant; it actually restored respiratory physiology (specifically at Complex I and IV) and stimulated ATP production in neuronal mitochondria. It also fired up the SIRT3 pathway, which is basically the cleaning crew for mitochondrial stress.
So yes, the research suggests you can artificially break that loop. It’s not just acting as a hormone; it’s acting as a substitute for a broken metabolic part.
