Mitochondrial Biogenesis

Urolithin A supplementation increases mitochondrial biogenesis markers such as NRF1, NRF2, and TFAM in muscle tissue. Increased mitochondrial count from cold-induced PGC-1α activation results in a higher metabolic rate, greater ATP capacity, and improved cellular oxygenation. Cold exposure produces a noticeable increase in daytime energy. The more mitochondria a cell contains, the more ATP it can produce. PGC-1α is a master regulator of mitochondrial production that is activated by cold stress, triggering the creation of new mitochondria inside cells. Urolithin A supports the creation of new mitochondria by activating PGC-1α. PGC-1α drives expression of genes needed for new mitochondria, replication machinery, and respiratory chain proteins. Cold exposure stimulates thyroid-stimulating hormone (TSH) and increases circulating T3, the active thyroid hormone that drives metabolic rate and thermogenesis. Fasting triggers mitophagy and mitochondrial renewal. Cold exposure activates mitochondria to generate heat and trains them to become more numerous and efficient over time. Polyphenols, plant-derived antioxidants, signal mitochondrial growth pathways. Mitochondrial biogenesis is relev…
