UNCOUPLING/DNP

Giving young mice a microdose of 1mg DNP had some interesting effects on their health. Thats an insanely low dose. While I'm usually cautious with DNP, this dose seems safe.
(1mg= HED, not sure if i calculated the dosage right)

Benefits:

Lowered weight gain
Strongly increased oxygen consumption, especially in brain
Strongly decreased free radicals concentration (hydrogen peroxide)
Increases life span by about 7%

Here is a great review on microdose DNP (HED of 0.5-20mg). And some interesting excerpts from it:

They tested DNP for neuroprotective effects and as in the study above the microdose was the most effective. It wan an HED of about 6mg, but as they increased the dose it became less effective.

"..dosed 6-month old aged C57bl/6 mice for 7-days at 0.5, 1, 5 and 10 mg/kg (HED 2–45 mg/day) and then the cortex was measured for changes in BDNF expression. Interestingly, BDNF was induced ~2.5× in the cerebral cortex at 1 mg/kg, but in a hormetic-like fashion, in that, the peak dropped going from 5 to 10 mg/kg, suggesting “less is more..."

Next, I want to clarify the myth that uncoupling is bad because it lowers ATP and damages the electrons transport chain somehow.
There is a drop in ATP, but it's likely transient and almost certainly not drastic. Uncoupling leads to mitophagy and increased ETC speed, leading to more not less ATP production .

Some quotes:
"...at 3-days of dosing rats with DNP at 16 mg/kg (HED of 150 mg/day) there was no measurable change in intrahepatic ATP content (ATP pool)..."

"... might selectively push those already marginally functioning mitochondria into mitophagy to shift the global mitochondrial population towards better functioning high ATP producers and lower ROS producers..."

"It is essential to note, that mitochondrial chemical uncouplers are not inhibitors of the electron transport system, but enhancers [2]."

"..3-days of mitochondrial uncoupling, induced by low concentrations of dinitrophenol (10 and 50 μM) in cultured human HepG2 cells, that there is an adaptive effect in that DNP towards oxidative metabolism, with an upregulation of COXIV and ANT3 gene expression, two nuclear genes that encode mitochondrial proteins involved in oxidative phosphorylation [49]"

"So collectively, it is possible that the net outcome is a higher ATP pool through more efficient mitochondrial functioning under chronic DNP treatment, than could previously be generated without the uncoupler."

Low oxidate stress is a sign of longevity . And uncoupling is a very effective approach at preventing oxidative stress, before it even happens.

"While antioxidants attempt to neutralize ROSs after they have been made [33,34], uncouplers actually prevent overt ROS production [35,36], a potentially more effective point of intervention."

The doses mentioned above might translate relatively well to humans since the mechanisms are highly evolutionary conserved.

"Rarely does a mouse efficacious dose curve translate perfectly well to humans, but since mitochondria are extremely well evolutionarily conserved from mouse to humans, and the effect is non-genomic (not relying on the conservation of a protein or receptor from mouse to human), then the prediction of translation is excellent relative to other platforms."

Random, interesting studies
