Core Functions Energy Production:** Participates in the oxidative breakdown of carbohydrates, fats, and proteins, providing energy to cells and serving as a core support for the normal functioning of mitochondria. Cell and DNA Repair:** As a key substrate for PARP enzymes, it aids in DNA damage repair, reduces the risk of gene mutations, and maintains normal cellular function. Aging-Related Pathways:** Activates the Sirtuins longevity protein family, slowing down the cellular aging process and improving age-related functional decline (such as slowed metabolism, cognitive decline, and skin aging). Metabolic and Physiological Balance Support:** Maintains endocrine stability, enhances insulin sensitivity, helps regulate circadian rhythms, and improves sleep quality.
