What Are Sirtuins? The Science Behind Cellular Longevity

Sirtuins are a family of proteins involved in cellular regulation, stress responses, energy metabolism, and repair processes linked to aging. In this video, we explain what sirtuins are, how they function in the body, and why they are studied in relation to longevity, healthspan, and healthy aging. Full article: https://longevityinsights.co.uk/what-are-sirtuins/ In longevity science, sirtuins are often discussed because they help regulate pathways connected to mitochondrial function, inflammation, metabolic balance, and cellular maintenance. Researchers study sirtuins alongside biomarkers of aging and other longevity-related pathways such as NAD+ and AMPK to better understand how cells adapt to stress and maintain function over time. Understanding sirtuins can help clarify why they are considered relevant to biological aging, resilience, and long-term cellular health.
