“Mitophagy, a form of autophagy, is the selective degradation of mitochondria. It helps ensure that the body's cells are metabolically efficient, ultimately serving as a trigger for mitochondrial biogenesis, the process of producing new mitochondria.”

“Exercise also promotes mitophagy (the turnover of dysfunctional mitochondria, fostering cellular resilience) and autophagy (the removal of cellular debris and damaged components). Learn more about mitophagy in this clip featuring Dr. Guido Kroemer.”

“The highest concentrations of mitochondria in the body are found in the rods and cones of the eyes, where they support multiple aspects of vision. Findings from a new study indicate that viewing a red light restores mitochondrial function in the eyes of older adults.”

“DNP belongs to a class of compounds known as mitochondrial uncouplers. It enters mitochondria and essentially "short-circuits" the cell's means of producing energy; however, since it reacts to boost energy production, the net effect is an increase in energy output.”

“The pomegranate compound is transformed by gut microbes into a molecule called urolithin A which causes cells to clear away damaged mitochondria and recycle their defective components for energy.”

“In the BFR group, pressure cuffs were wrapped around the upper thighs and inflated to 120 mmHg for two minutes after each sprint. The comparison group rested without cuffs. Muscle biopsies were used to study the participants' mitochondria, the structures inside cells that produce most of the body's energy.”

“Every other day fasting primarily alters the gut microbiota composition to promote the generation of acetate and lactate and this increased mitochondrial density in adipose tissue. The higher mitochondrial density in white adipose tissue caused the "browning" of the fat which results in increased energy expenditure through non-shivering thermogenesis.”

“Mitophagy is a type of autophagy, an intracellular program involved in the disassembly and recycling of unnecessary or dysfunctional cellular components, that selectively targets mitochondria.”

“Other hormetic responses to cold exposure include increased production of PGC1-alpha, a protein that promotes mitochondrial biogenesis, the production of new, healthy mitochondria, and the activation of brown fat – a phenomenon once thought to occur only in newborns, but now known to occur in adults, especially after cold exposure.”
