“Mitochondria are often called the "powerhouses" of cells, and their proper function is essential for sustaining energy balance and health. In a new study, researchers at the University of Cologne investigated whether the amino acid leucine can directly influence their activity.”

“It damages cellular components, such as lipids, proteins, mitochondria, and DNA, and is implicated in the pathogenesis of many chronic conditions, including cardiovascular disease, neurodegenerative disorders, type 2 diabetes, obesity, kidney dysfunction, and others.”

“Currently selected for this coming member's digest by team member Sofia D.”

“Short bursts of high-intensity exercise do not use mitochondria which means glucose is the only energy source for anaerobic exercise. This is an interesting study but still, a pilot trial and more data are needed before conclusions can be made.”

“Some of these strategies include periodic fasting, which serves as a sort of “housekeeping” function – ridding the body of senescent cells from time to time, and exercise, which acts as a hormetic factor – a low-level stressor that primes your body to respond more effectively to larger ones and may also be especially suited to tuning up the mitochondria…”

“Since nicotinamide mononucleotide is found in a variety of food sources such as vegetables, fruits, and meat, future studies will focus on understanding whether it also prevents age-related physiological decline in humans.”

“Impaired mitochondria can generate more reactive molecules that damage cells and further fuel inflammation. Cells help limit this damage through mitophagy, a cleanup process that removes and recycles defective mitochondria.”

“In a previous episode, entitled "Maximizing Your Mitochondria with Magnesium," we learned that 45% of the US population is deficient in magnesium and the important role magnesium plays in mitochondrial function and how this relates to exercise performance by ensuring your muscle cells have the highest oxidative capacity (ability to produce ATP or "energy") possible.”

“Reversing the Cardiac Effects of Sedentary Aging in Middle Age—A Randomized Controlled Trial - In sedentary middle-aged adults, 2 years of regular exercise improved heart function and reduced heart stiffness, potentially lowering future heart failure risk.”

“Another important way exercise delays muscle atrophy is through the induction of mitochondrial biogenesis which is the growth of new healthy mitochondria. The fact that urolithin A was able to induce biomarkers of both mitophagy and mitochondrial biogenesis is quite compelling.”
